Out of square issue

Hey David,

how did you check for rectangularity? I find using a bar gauge for a first check for identical diagonals is very useful. When you adjust the rails then, it is good to loosen the eight bolts that attach the X axis to the two Y sliders a bit, then do the squaring of the rails with the bar gauge, and then tighten the X axis bolts again.

@Aiph5u

did you first check your machine for rectangularity, like → described here .

After you ensured that both diagonals are perfectly equal, then you can do the following:

1. Shut down the CNC controller.
2. Disconnect both Y stepper motors from the controller.
3. Loosen slightly the four bolts on the top of every Y carriage that attach the X rail to them.
4. Move both Y carriages towards front until they both touch the front end.
5. Retighten the eight bolts.
6. Restart the controller.

Which controller do you have, Buildbotics-derived Onefinity Original Series, or Elite Masso G3 Touch?

By the way, when mounting the Onefinity CNC to a table top, I always suggest not to use the wood screws that come with it, but bolts instead, or better bolts in sleeves (e.g. brass) with bolts in it. Their diameter would need to be exactly 8 mm:
