      The Archon Revision 2.0

      Hello Everyone!:) If you like it!!! please vote!!! it only takes a minute thanks

      here is the link....
      http://bit.ly/PowerPackVote


      This is my first build post ever here on Openbuilds.com and I want to take the opportunity to say how amazed I am at the amount of talented people there are here at Openbuilds. I will try really hard to be as thorough and methodical in my approach to describe my setup process and my theories behind the choices I made to make this Gargantuan of a machine a real possibility!!! I will do my best, step by step, to describe the build process. thank you Makerparts.ca for being one of the only trusted Canadian distributor's "that I know of" of Openbuilds gear here in Ontario helping builders and hobbyist's alike to stay inspired and build awesome stuff. and course thank you to all that have inspired me here on Openbuilds.com and also thank you to Openbuilds and its co-founders for not only providing the tools and materials that builders need in order to make all of this happen, but also providing a solid platform and ideology for its business model and helping makers alike stay connected by building a community of like minded individuals that ultimately share the same passion. to build things new and old, to build things never once possible and build them better. and last but not least I want to thank my family for keeping me motivated and making sure I didn't pull all the hair out of my head.:banghead::blackeye: My beautiful girlfriend for standing beside me through the toughest of times, and of course Bentlee the dog, who I could always count on to remind me that eating and drinking was important and that no matter how fixated and focused I was flexing my brain muscles, it was important to still use the washroom. :rolleyes:

      so in the words of some sage like advice from some Merlin likeness of a man that may or may not have existed at some time or other,:ROFL: these are the words that kept me focused on my goal. :thumbsup:

      "Necessity is the mother of all invention".....so without further adieu here I go!!!;)

      STEP 1 SOURCE ALL THE PARTS!!!


      Probably the hardest part of this whole process was sourcing all the parts, and establishing what exactly I needed in order to complete this build. I first established that I wanted this to be a big machine with a huge cutting capacity roughtly 10'X5' machine, in order to accommodate full sheets of 4'X8' sheets of plywood. because it became apparent to me that some of my customers and potential markets where limited to what I could physically cut with my Smaller Cartesian machine and second I was tired of not being able to nest a full sheet of material, to cut down on material waste and not having to cut down an important workshop material I use for my customers with a skilsaw in order to fit the raw materials onto the machine was paramount.:D and three, I wanted to include some un-traditional adaptations to this build so that my power transmission could exist in a more relaxed sense with less likeliness for the belts I chose to prematurally fail, Why did I choose Belts??? and also why did I name it the Archon? well all good questions. I know that belts may have not been the best solution for such a large machine, but I wanted to try something new and I wanted to challenge what is so far thought as possible in regards to this machine variation's limitations. second I believe that belting solution's offers the user greater motor step quality because of tight tolerances of the belting and how well the pulleys and belt interact with one another. So I knew for sure it had to be super strong laterally and bi-laterally because I knew I really wanted to try some Nema 34 monsters running in tandem for the Y-axis to offload the strain in the longest direction. It's the one direction you really don't want your machine to struggle or strain with because of the long traverses it takes in both Y- and Y+, so I needed motors capable of travelling long distances and with enough torque not to get tired to encourage misteps in both directions. So obviously I was overwhelmed at the many possibilities so I went to the drawing boards and started planning.
      I really liked the Ox Idea that has been floating around on openbuilds and the net, but there was no known solution's on line in regards to supporting the Nema 34 class motors, so I had some hard decision's to make. so I drew up some basic sketchup files as to how I wanted all the plates to be, and designed all my plates around the Nema 34 platform. o_O I didnt know what I was getting myself into until it was too late lol :nailbite: Wow What a journey its been. I had a machine barely capable of cutting aluminum, it was obviously possible for me to cut out the parts I needed on this machine but the quality would have suffered and all of the mounting hole's in my plates had to be super precise. so I got in contact with Chris Laidlaw from Blue Ox solution's to help me bring my design elements to life. So I sent him what I had for overall dimensions and final formats for most of the plates and asked him if he would ever so kindly cut for me the Ox style plates I desperately needed in order to accommodate the Nema 34 Behemoths I wanted to employ in this build. :cool: Thank you very Much Mr. Laidlaw :p you probably don't realize how pivotal and crucial you where to the success of this build, thank you for all your help and efforts, especially in trying to help me find my possibly lost or stolen parts ordered back in Late October and which I did not receive until the week before Christmas or the start of the holiday season to be politically correct. My beloved plates spent a good portion of there life laid over and buried under millions of parcels at a border crossing customs office in B.C Canada for almost 2 months!!!:zipit: I was obviously sick with anticipation and starting to loose hope whether or not this Monstrosity build was such a good idea?! but Chris's gentle approach in addressing the situation lol :ROFL:, reassured me that he had contacted Canadian Officials, and that my parcel was still on route, but it was layed over at a beaver dam, and the moose and RCMP officer in charge of delivering my parcel was stuck at a river crossing waiting to board the next canoe to my location deeply nestled in the Canadian Shield. as you can see Chris had a great sense of humour and helped to keep me positive about the whole situation. Thanks again;)


      Oh yah before I forget I named this contraption the ARCHON because they are tough to axe-down in Starcraft II, and well If could spend more time playing that game, I definitely would, OK talk to you guys later, I'm going to go ladder up on SC2!!!!!!! .......:cry: Man do I ever love this game.lol:p:D;)

      I won't go into full details here in this section as to the exact parts list because I have included it in the below section of this build thread. but I knew for sure I needed 3x Nema 34 motors, 1x Nema 23 motor for the Z axis, A C beam actuator kit "cause I liked it", at least 50' to 60' feet of 3GT belting, pulleys, delrin wheels, lots of different sized lengths of M5 bolts, nylock nuts, aluminum spacers and washers, power transmission couplings, more on that later. and a boat load of structural aluminum, provided to me from Openbuilds/Makerparts. and so far this is only the structural aspect of my machine, not including yet all the wiring, proximity sensors, main power source, VFD inverter for the spindle, Air cooled high torque high speed spindle, motor drivers, and controller, liquid oil sprayer for metal cuts. and possibly some new CAD and CAM software to help me with design and roughing and finishing cuts!!!! mostly wood and Aluminum, Yah I know what your thinking lol, Exausting....right? :cool::p which brings us to the next part of the equation,

      STEP 2 FRAMING THE TABLE FOR THE BEAST!!!!

      The Structural Process wasn't as straight forward as I wanted it to be, but usually none of the projects I tend to take on are, So I went to the drawing board.
      So since this was going to be a really big machine. I needed an actual table for it to sit one for its useful life. So I planned and Engineered a large format wooden table using structural timbre. 2x4' and 3x4 sheathing for the top, as well as a storage shelf located underneath. nothing super over the top but of course since our climates where I live are so very much extreme in overall fluctuations in outdoor temperature, I had to pay close attention to the warp in my wood. the last thing I wanted was a table that was obviously off kilter, I didn't want this off-balance issue to become a transferred issue to the ARCHON. so I paid close attention to my level guide and tried the best I could to make sure that the foundation was alot more like marble than sand, symbolically speaking. :thumbsup: also I used some big I think 3" swivel casters for the feet, to allow the table to move as freely as it could In my workshop/dungeon lol :troll: "Uruk we need more logs for pit's of sauron", "trying to be funny, but anyways the table turned out well.
      The first time I sheathed the top of the table I wasn't using my thinking cap and I was trying to use scraps around the workshop so that I didnt have to spend anymore CHA-CHING than I had too, I like to try my best at using scraps when I can to save on costs, and not to waste, Cause I like to live by that old fashioned point of view, "waste not want not" and I like to be mindful of our Canadian Caniferous forests" and all the little creatures that live and scurry in and out of it. "Enters In Rush the Canadian Band" playing the trees. :D I know that American's Love Rush, even though they are from Toronto. anyway's not to get too sidetracked. I re-sheathed the table using tongue and groove 3/4" plywood and the table turned out beautiful and flat, and level.
      take a peak at some of the pictures you will notice a square gap in between two pieces of top sheathing, this was done on purpose because I am thinking I want to employ some wood vise clamps underneath the table some how so that I can possibly engrave on materials on there sides rather than just there faces. :ROFL: I actually had to lift the ARCHON off of the table using rope I had in the shop/basement/dungeon/man cave. I had to lift it up from the beam rafters. I was petrified at this, my first attempt at the sheathing was horrible and the machine was way of balance, so I hit the high speed dirt and did the unthinkable. I doubled up a bunch of rope, trying to remember some knotting skills I learnt back in beavers/scouts and got to it. :confused:

      20180117_081125.jpg 20180201_124132.jpg 20180201_124143.jpg 20180201_235322.jpg 20180201_124154.jpg

      So I managed to balance the frame well enough in the air, as you can see I was already a good portion of the way through the build when I decided to make a change to the top sheathing, but I honestly believe it was necessary and it had to be done if I didn't want more headaches later on in the build. so there are of course some "spoiler alerts" early on in this build but I mean who likes suspense anyways?! So there you have it for the "tables table."

      STEP 3 FRAMING THE ACTUAL BEAST!!!!

      I framed the ARCHON with:
      4x C-beam 1000mm long Aluminum beam extrusions
      4x 20x80 1000mm long Aluminum beam extrusions
      6x 20x40 1000mm long Aluminum beam extrusions
      3x 20x60 1000mm long Aluminum beam extrusions
      4x 40x40 1000mm long Aluminum beam extrusions

      I combined on both sides the C-beam and 20x80 beam to make up the two Y travel ways.
      I used the 20x40 rail for rib support. I used the 20x60 rails for end ribbing support and last but not least I bunched the 40x40 rail to make a super beam 80x80 rail for the X travel way. I used basic end joiners for the initial fitting of all these components, but then later realized it was important to make myself my own end joiners to help stiffen the frame. I needed all the strength and stiffness I could get so I over engineered many aspects of this build in hopes that it would encourage the machine to become more rigid and less prone to sagging and especially in the Y traverse. I milled out some cool looking end plates and side end plates to replace the aluminum joiners. using my small cartesian machine, I only ended up cutting out the perimeter shape fully through using only my small cartesian and some WD-40 for lubricant. I didnt mill out the holes I just allowed my machine to plot the holes on the plates by marking the points with shallow cuts and then used my drill press to finish the job all the way through. I used some 1/8" thickness aluminum to join together the C beams and 20x80 rail using nothing but 15mm 5m bolts and the accompanying t-nuts to hold it all together. to my surprise this joining method worked very well and I do not see any potential sagging as of yet in the centre of the Y beams fingers crossed this will be the only thing I will have to do to make sure that the Y travel does not become compromised over time by weight, friction and gravity pushing down on them by the weight of the X travel way and the Nema 34's
      I of course spend a great deal of time threading the holes of the aluminum extrusions by hand with a typical tap and dye kit. using lubricant to aid in the shaping. all in all I sourced most of my aluminum from a great local metal fabrication shop that has been family owned and operated by some amazing people here in my small town. I have much respect for the business owner, and him and his family have been an integral part in shaping the economy and business sectors in my area for a very long time. and in spite of the ongoing and recent economic downturn that is hitting many north american sectors both in the states and in the Canadian north him and his family have pushed through and stayed strong. I really appreciate the help thank you, your help was integral.
      In regards to the shaping and polishing of the brackets I designed for myself I didn't do anything special to them, I just hit them hard with a flap disc to take away the scratches and dents and buffed away most of the old oxide layer no polishing. I made holes in two of the Y end brackets to hopefully allow some fancy Proximity sensors. I am still not sure but the holes are there just in case. the plates I made for ends are also 3/8 structural aluminum nice and thick and hecka-strong!!!! I love working with aluminum.

      20180117_080915.jpg

      20180117_080923.jpg 20180117_080928.jpg 20180117_080939.jpg 20180117_080951.jpg 20180117_081009.jpg 20180117_081017.jpg 20180117_081026.jpg

      I also made sure to drill some over-sized holes into the end brackets to accommodate the wiring.
      not much else to say really. It took awhile to get a handle on how I wanted to fashion everything together. and there was definitely a bunch of trial and error and it definitely took longer than expected, tapping the holes took a long while and fastening everything together one m5 bolt at a time took much patience. but overall it got finished and that's the main thing. ;):D oh yah one more thing I fastened the table to the table using 2 hole and three hole brackets using some construction zinc screws and making sure while doing this that the ARCHON was nice and square and now there is barely any play in the Y although I am going to be experimenting with some square supports underneath all four ends of the Y beam to see if this strengthens the center where both sections meet to make the overall length of the table. fingers crossed.

      STEP 4 POWER TRANSMISSION AND PLATES!!!!


      This was obviously going to be the hardest part of the compounded equation. How do I drive this thing??? well it was obvious to me that I wanted to employ belts so I did research on the different sizes and pitches of belting I had already had some experience with 2GT belting but realized it had some draw backs being only 6mm length and being overall smaller in size and strength. so I opted for the next best thing I chose to use some 3GT belting 9mm width and used the pulleys and idler wheels to accommodate them. I found a pattern in assembling this and just followed it the whole way through. also I knew early on I wanted to have two belts on either side of the Y traverses running in synchronicity at the same time helping each other pull the weight of this mammoth. I knew there where going to be some timing issues to allow the belts to work in perfect harmony but I was planning on using threadlock on all the couplings and pulleys so that they stay as mirrored objects to themselves, so that the belts are all dopplegangers to themselves. I also used some Love-joy couplings regular sintered L-050 couplings with the spiders in between. I used the 0.50" and the 0.25" couplings together with the flex shaft spider in between and married it all together using loctite threadlocker. also in this equation where two very small engineered bracket ends that I fastened to the top middle of the Y stiffener plates to allow the 0.25 steel rod to pass through and marry all the components together. I used a course threaded dye 0.25" to make the end threaded, so to pass through and used a 0.25" nylock nut to keep everything nice and tight. The whole process was tricky but it was definitely manageable and turned out great. I have files of all the plates that I have included to go along with this build at the bottom of the page, there is no sense in me describing every single step I used, because I am starting to realize I wouldn't have had the patience or the energy to be a writer. and I understand that pictures tell a thousand words. so please forgive me for not being as thorough as I would like to be. but I don't want to veer anyone of path, and make for a very boring and dull book. lol so to speak. I want to say thanks again to Blue Ox solution's for your help and a huge shout out to len1007 ebay member for all the awesome electrical component ideas!!!! thanks.:rolleyes:
      I fastened the stiffener plate and Y plates together using 100mm long M5 Metric black oxide bolts. and used a combination of aluminum spacers and washers to get all the pulleys and idler wheels to line up straight in conjunction with the 9mm belts. as you can see I am still waiting on lots of components for this build like all of the belting. here I have only one belt connected at this time, because I am still waiting on all the length I need in the mail. I really wanted to get this whole build straightened out to have all kinds of finished pictures for the openbuilds "POWER PACK GIVEAWAY" but sadly I wont have all the components necessary to have any fully complete pictures but I will post them as soon as I get all the pieces put together. I am still waiting on longer 120mm m5 bolts to finish assembling the X gantry to the X Rail and belting. I should have enough wheels pulleys and idlers to finish setting up the X gantry.
      Also if you take a look, I have a picture that shows how I have the plates running on the belly of the Y rails. all I needed to use was three extreme delrin wheels underneath spaced apart equally using aluminum spacers and these Y plates are rock solid!!!!! I was super happy with this part of my build.

      STEP 5 CONCLUSION AND FINAL THOUGHTS

      So basically all that is left to do now with this build is power it using the power of flowing electrons!!!

      All joking aside lol to fully finish this build I will most definitely need a solid power supply, solid motor drivers, all the wiring and a nice interface controller between the machine and the host computer. I would like to try my hand at some fully fledged 3d nesting cad and cam software like Mach 3/4 and also get into milling more aluminum. I am thinking of including a nice oil jet sprinkler on the head of the z axis, to keep the cutting piece nice and cool and create less friction for my spindle of choices carbide bits. a new spindle with a VFD and pendant would be very nice since I have been using regular router spindles to great success, but am very limited to the rather slow RPM's and torque. also a bunch of cable carriers would be an asset as well, cause i dont feel like hanging all the wiring from the ceiling with zip ties lol jj
      To conclude this build I would like to say thank you to open builds for offering some kick-butt building supplies and materials. and also I would like to thank the online community for all of the much needed inspiration and ideas!!! truly Openbuilds would not be as great, if it were not for the huge support of its members!!!

      My next builds are going to include an ACRO system, because I am intrigued at this laser business, also I would love to play with a mini-mill for PCB Milling purposes, or one similar, and I would really love to make a larger than normal 3d printer based heavily on TEVO black widow format with nema 23's instead of 17's possibly with an updated MOBO in the shape of a smoothieboard perhaps? :D

      anyways thank you for allowing me to share with you guy's and gal's my build and thank you in advance for the chance at the awesome POWER PACK SURGE GIVEAWAY!!!!! :)

      1. Special Notes

        The one thing I could not buy even if I had the money was patience. this project/experiment has been a large investment of time and money and patience. so breathing and knowing when to walk away and clear my head was a must. this has been one of the most complicated projects of my life and it allowed me to test my strengths in solving compounded problems by being forced to establish a methodical approach to solving the apparent mechanical and power transmission challenges apparent in any build "especially this one." and I am happy to be almost complete, Fingers crossed it will work as expected.
