Can you do a dry run watch for binding?? The couplings are also easy to strip. Also hard to catch if you don’t mark them.
May even double check step motor plugs for a good connection.
Do dry runs till you figure out what’s up . Go to a scrap piece of material fire the torch to make a pierce hole zero out . Jog around the table return to zero fire the torch to see how far off you are and which direction.
disconnected both Y motors tested & the x axis binds…
reconnected both Y motors and disconnected X and tested, Y axis binds…
My machine was ordered in Sept 2022 & assembled in Nov 2022. I have mostly been cutting with the standard consumables at 48-129ipm I work mostly with 1/8 & thicker.
I never had any issues until I started pushing the machine faster for the fun cut consumables & thinner sheets… although I have cut a few small signs at 225ipm & standard consumables previously with out issue.
If it’s the X axis, check the two bolts that hold the lead nut bracket. If they are loose, you will lose motion on X direction changes. It could also cause binding, because the lead nut is not aligned with the screw
I don’t know if this is of any value, but jogging at high speed is not likely to show up the imperfections of movement. I would suggest jogging at no faster than 50 ipm and for the z axis, really slow. You are looking for any inconsistencies.
Agreed with you asking for more help from langmuir.
Certainly could be some electronic interference. That is a chapter I have not had experience with.
