      Recently bought the c-beam kit. In my attempt to assemble it I discovered that one of my precision shims in the wheel kit is NOT a precision shim! How do I go about getting a replacement so I can continue my build?
      1. Mark Carew
        Mark Carew
        Hello jrclarke sounds like you may have a defective shim. Its rare but does happen from time to time. The best thing to do is contact the Part Store Team and they will take care to get you up and running right away. [email protected]
        Thank you

      Hi! I just assembled my new CBeam machine. I have the steppers wired to a Tinyg and now I think I'm reading there's no more TGFX? I actually have no idea what I'm doing, What I should be looking for as far as (a program to run the machine)? I would rather not run CHillipepper because I don't often have a reliable connection. I'm at the beginning. Could you please steer me in the direction of progress?
      1. Mark Carew
        Mark Carew
        Hello, I have not tried the Tinyg but I would think that you could use it with any grbl control software like grbl panel . Please have a look at the Software section of the build - https://www.youtube.com/watch?v=HVR8pABCHXI&feature=youtu.be&t=4152
        You should find everything you need in the Files Tab of this build for software as well. Hope this helps

      Hello I am a virgin in CNC builds and have one question of many on my first build, can I hook two steppers to one driver for my y axes? so what board would I need a 3 or 4 axes? All of this is getting a little over whelming for me.

        Its really not complicated at all, once you dive in it will all begin to make sense and next thing you know you will be designing your own machine :) Be sure to use the forums to post questions as this will help others that come along later with the same questions. Have fun with your Builds!

      Hello Mark, I would like to make or buy a cheap XY stage for my microscope. I have not played with stepper motor before. What is your suggestion? thank you
      1. Mark Carew
        Mark Carew
        Since there is no real load on the system I would say that you could go belt drive but lead screw with an anti-backlash nut block would be nice as well. Really I think you will have to take a look though the great Builds here on OpenBuilds and try to decide what will work best for your application. Wish I could be more help but I think it will come down to personal preference on this one,

      What is the advantage of having a 24 v power supply over 12v?
      1. Mark Carew
        Mark Carew
        A 24V supply will charge the stepper coils more quickly and give a little better over all performance.

      Hi Mark! I just assembled the c beam kit and I had problems with some parts.
      the spindle mount is not threaded properly for the screws and one of the lock collars has the same issue with the screw.

      Mark this is all new. I found you on you tube with c-beam, great video and I know it took lots of work payed off you found me. I'm very hand on and mechanically inclined. This will be my first build and first set up to learn in and outs of CNC. My question is, can I build the c- beam cheaper if I piece it together with your parts store or just buy your bundle kit?

      Mark - I see you provided parts list for SolidWorks. It didn't have the 8mm Acme Lead 1040mm and 540 mm screws. Wondering if you had them?

      In your page for the OX you have instructions for a Spoiler board. In the instructions it talks about Hold Down clamps that will be available in the store. Have you added this item to the store yet? I did not see it when I was looking.

        Hello Brett, Yes we have plans to offer these but at this time do not have them complete. We apologize for the inconvenience and hope to have them available soon.

      Mark, I am going to build a large C-Beam based CNC Router. I want to use a 750 mm X axis with a 1500 mm Y using 2 C Beam spaced 80 mm between the 2. I need help with the best way to locate the NEMA 23 motors. I would like to use an ACME on the Z with at least 6" of cutting height. I need help with this design and all the parts required .
      1. Mark Carew

        I think the best thing for us is recommend is that you start a build here.
        Here on OpenBuilds®, you will have access to valuable feedback from many like minded individuals and Builders as well as resources and tools that can't be found anywhere else.

        Thank you

      Hi Mark: Is the (CNC xPro V2 Controller Stepper Driver) a good replacement for the electrics that came with the Plll?
      Its still working ok but failer may be around the corner.
      thanks bobada
      1. Mark Carew

        Yes Bob I think the xPRO would work great for the PIII

      Hi Mark. I am looking to buy a CNC bundle and think that the OX fits my build size requirements the most. I was hoping for a build size of 2' x 3'. Do you have a parts list for the OX able to handle that build size? I really like the C Beam machine as well and wonder what is the largest size you seen one built. I am looking to mill Aluminum hopefully up to 1" thick.

      Hi Mark
      I'm very interested in buying "V-Slot™ Linear Actuator Bundle (Lead Screw)".
      Do you have skp files or any other CAD of this bundle. I hope I can purchase it by this week.
      Thanks!

        Besides, if I make an order today, how fast can I receive it.?
        Seems it will release on Nov 20 but I want to get it as quick as possible.

        Thank you very much!
        Also, do you have some components similar to 80/20 that can support this bundle and make it like a gantry crane?
        Or does this lead crew actuator match 80/20 T-slot aluminum.
        Thank you again Mark

      Hey Mark...Do you know when the 1500mm 20X80 will be back in stock? I want to build a 2X4 machine, but may have to downsize as I am anxious to get things ordered and it looks like 1000mm is the longest in stock

      Thanks

        Hello @leversole Looks like these will be back on the Part Store in or round about two weeks, Thank you and all the best with your Build!

      I am interested in building a long arm robotic quilting frame. The sewing head weighs 47 pounds so I need a strong large frame. I am interested in your C extrusions but need some specs on the deflection for a 3 meter length. I only see 1500 mm is the largest rail but I am willing to piece it. Thanks for any advice.

        Hello @Joe Neill
        Thank you for contacting us.
        At this time we have not completed testing on the C-Beam actuators but we are working to have them done as soon as possible. You can look at the deflection values of V-Slot 20x80 that may help to get you closer.

      Hi Mark.

      A couple questions. I cant find the drawings for the roller wheels. Also I live in the Philippines and shipping/import duties is very expensive here.

      I have a source of Bosch style aluminum profile, will that work without changing the build plate dimensions? Also Is it possible to make the build plates from 12mm acrylic?

      I have a homemade router but it is not very good to cut aluminum with.
