    Wow @Peter Van Der Walt and @Alex Chambers ,, this was super helpful,, I over looked this in the beginning,, I got to the page , I homed the machine which I had done from the beginning , from the homed spot the machine is away from the X and Y locations a few MM, I then jogged to the extreme x and y travel and recorded the DRO,, how do I change these values?
    I turned off the soft limits and air cut the job it never seemed to go into a dangerous location,, so I was able to cut the job then enabled the soft limits I know this is not the fix, but it got me over a hurdle,, Thanks

    A lot of people have used ball screws on their OpenBuilds machines. I can't say for sure the LEAD 1010 was one of them, but it uses the same x gantry plates. Any modification to the Y could me applied with minor modifications. Check out the builds section of the forum.

    I just purchased some 1/8" and 1/4" dia. compression mills. Has anyone used these on their Lead 1010? Are we able to cut 18mm (3/4") baltic birch ply in one pass with our machines or is a stock Lead not strong enough? Some hobby machine operators do an initial pass at a depth just beyond the upcut-tip and finish off with 2 or 3 more passes. What are some successful strategies you're all using with compression mills and BB ply and the Lead 1010 specifically?

    I have a workbee which is basically the same machine. I run 1/4" compression bits through 3/4" ply in 3 roughing passes at 100 in/min leaving .025" for a finish pass at 40 in/min. Dial on the Dewalt is set to 3.5. I've found the finish pass is the key to having very little clean up off the machine since I prefer to ramp into the stock instead of plunge. Ramp angle is 2 degrees.

    I did an upgrade to 16mm ball screws and HGH15 linear rails on a LEAD 1515. I’m very happy with the results.

    Questions before I buy one of these..

    Why on the High Z mod is the Z axis Flipped from the regular version?
    Can it be installed the original way.. I dont understand the need for all that additional useless travel.. Or atleast it appears to have 3/4 of the total travel out of the work area..unless there was a sale on 2ft long drill bills?

    2nd.. its 2020 link the accounts on your site to the forums, feels like 1999 having to create a different account for the same website.

    The whole idea of the high Z is to give the additional travel for the Z axis, and it will require very long bit to use the entire travel of the axis. If you don’t need that much travel, then save your money and just do the normal LEAD kit. The only one that has the same functionality of the Hight Z mod built in is the 1515, which needs the extra strength because of the longer X axis. I do prefer the extra Z, even if I only use it 5-10% of the time. But, that’s just my $.02.

    It isn't useless travel if you are engraving on thicker work stock or boxes. If you read the product description, it is for:
    I built a rotary lathe using the High Zmod kit. I flipped the z around so the whole Cbeam goes up and down. But, you need to join the two levels of cbeam gantry plates to be sure they are locked together and move in tandem. Here is the post LEAD Lathe

    I also sent one of these plates to a gentleman in Texas who wanted to do the same thing you are asking about.

    Hi- Putting together my 40x60 lead machines and ran into a couple snags. One I had a very hard time putting on the brass compression nut.I had to file the end of the lead screw and finally go it on. I noticed a couple of new pieces of lead screw I have has a more finished end and the nuts go on easily. Issue two is I had a very hard time getting the lead screw through the plastic nuts. One was fine and the other was very tight and I had to use a wrench on the compression nut to get it through. I am a distributer and have had these for a few years maybe the spec has changed? If they are initially tight will they wear in? On the other side I am going to run a short piece of leas screw in and out chucked in my drill. does anyone use any lubrication on the lead screw? Thanks

    Where did these leadscrews come from? Different supplier, or OpenBuildsPartstore? Same for the leadnuts and tension nuts - different vendors may not mix as well as genuine parts

    The 1540 I did not buy from Open build because they didn't carry it when I started this project. Everything else is from Openbuild.

    That would explain the incompatible fitment, our parts' tolerances are matched to ensure good fitment with other components. Any parts that come from a different source would be of a slightly different spec/tolerance/fitment/finish.
    Replacing them with our screws (which have a slightly smaller OD to ensure good fit inside the bearings, leadnuts and tension nuts) will resolve all your issues. Continuing to force an oversized screw through all the other components will cause more damage to all the parts and cost more in the long run

    Thanks that is a sound plan. I will order up a couple new lead screws. My machine has sort of evolved it will be a 40x60 with the high package. I will have to post pictures went it goes together. Best Regards Bill Sterling

    Heya guys, machine is working some time now, and wanted to access the eccentric spacers on the gantries to adjust the preload on wheels after some time of usage. Any tips on how to easy access those when the machine is fully assembled?

    Hi!
    I'm a new Lead 1010 CNC owner. Today I've finished the building and electronics. Now the machine is moving and go home correctly.
    The problem is that I've tried hello world job and at 5 seconds an error occurs: error:9
    I don't know how to solve.
    Thanks in advance!

    No spindle yet. Shielded wires and xtension limits with EMI filter.
    I think it's a software configuration error because when it starts a job, first z axis hits z limit and error 1 flashes a second and then error 9 in the screen. My seller send me different motors and I had to reverse y and x axis motors. Maybe is this the reason?

    Thanks again.

    Where is the kit from?

    Where is the gcode from? Fusion? Did you set the Z start/end height to -10 (0 will hit switch)

    Ok guys. It was my fault... I didn't set 0 point before start the job. It works fine! Hello world job done!
    Thanks!

    Hi Again,

    I saw a post on the last page somone requesting if the Lead 1010 has a full model for Fusion..
    I would love a copy if someone has one.

    Id like to be able to run stress analysis on it, as I plan on buying a lead 1010 with Highz mod because it has a larger area then I require and would like to mock up and test double xlarge y axis and play around with beefing up x axis.
    I dont want to just wing it and over engineer it adding alot of undue weight.
    Plus an official model would have all correct screws and nuts to provide correct analysis.

    Thanks.

    Anyone know some search terms I could use to find differences between a raise/lower zaxis gantry verse the typical single axis?
    I am wondering if it would provide more rigidity.

    Also wondering about the possibility of both, depending on the type of cut..
    Like how could I have a high z gantry that raises and lowers.. but also a single zaxis that could also raise and lower..
    If possible does any software accomendate a type of telescoping axis?
    To be honest.. I just think telescoping as a broad term covers the fuction it would be performing and may not be an accurate discription.

    Thanks.

    I have seen builds where the entire X axis moves up and down, with the Z gantry fixed. That would give you possible the best of both? You would need 2 Z axis motors, but I’m not sure how much flex you’d get from that. Haven’t heard anyone say anything about it other then some pictures.

    You could always just not mount the X axis as high as it can go. Just mount it as high as you will need it. You will probably find you will not need to beef it up. I am rebuilding my current CNC machine based on my version of the High Z mod and I am making it so the entire X axis can he easily mounted either up high for 3D carves or down low for sheet goods. Up high there will be end stops to ensure the two sides are at the same height and down low it will rest on 1-2-3 blocks while being fastened to ensure they are the same height.

    Netechsys,
    I looked at that idea, its were I got telescoping term... but as it is, they seem very expensive.. the telecoping actuators that is.

    Giarc,
    That is an interesting concept.. I am wondering if you meant that one of your Y axis supports is floating.. I have considered that approach, but it is taking me down a more PLC path and not a simple driver board configuration..
    If I could decide on stops and pauses combined with radial arm locks, as I would assume round bars would make for the best open ended solution, I might be able to persue that course..
    Thats all assuming more operator interaction and less automation..
    But it could be a solution.

    Nothing is floating. It is like the LEAD High Z but with custom plates that hold the two X axis beams together on each end. The plates would be loosened to be raised or lowered. It will not be a super simple thing, but simple enough. It would only be raised to the highest spot (as pictured) when I am cutting very thick things like foam, which is a rarity.

    I like this idea, Giarc, should have thought of it before I built my machine. May do a conversion one day to facilitate it (only MAY! :D)
    How about two or three indexing holes to have a preset height. It could simplify setup every time you change height.

    I had thought of that and even designed the plates for it. In the end I chose the easier method. I can rest it on 1-2-3 blocks on the rails which gives me those 3 different heights plus the highest point. I could even make different sized spacers, but I figured the 123 blocks would be easiest and the most accurate.
