Hey All -

I think I'm going crazy - I can't get my Y axis to show any changes when I save distance travel adjustments. The data will save and write to the adjustments screen but with the actual movement of the axis nothing changes, it keep repeating the error. The X axis works fine and I was able to make all the corrections I needed but the Y axis wont actually save my changes.

I have enabled screw comp in the motor config screen and I have done the standard process. (thinking about this after I wrote everything - I wonder if the file doesnt say "Y" but the screen does and that is causing my issues - will check tomorrow)

I dont have any images today but I may get some tomorrow.

Also at one point I did have an issue with travel limits not matching - I dont remember if it was for Y or X. I went into the CNC-__.tab file and removed all the extra travel I didnt need.

I have a feeling this issue is caused by some backend file not being correct - but IDK

any thoughts ?

I have a video uploading to youtube right now that I'll put the link here once its complete - but what I have found is that if I put the correction value in the next row down it'll work .... as in

if you are working on 0.0 > 0.5 instead of putting the variance in the row for 0.5 put it in 1 and it will impact 0.5.

The video has 1 hour ish remaining

will do tomorrow

here is the vid

thanks for posting the video, i'll take a look at the video later today, in the meantime please post a report.zip so we can see and use your setup.
how much backlash does this machine have on each axis?
have you seen uwe's and alan's setup / test videos? on this thread

the backlash isnt great - I am using lead screws vs ball screws - but I dont think hardware is my issue - as the software fields are not responding only for one axis.

see my report attached

But overall i have sorta moved on by just shifting down my compensation to the next interval and it will change the prior interval ( hopefully the video makes sense )

Yeah i watched all the vids on how to do this - my x axis is complete its more of why do i have to put my 0 to 0.5 compensation in the 1.5in section to get it to impact the .5 compensation. everything is shifted down one rown to have an impact on the row above

ok thanks for the report, we'll investigate.

leadscrews..ugh...time to put some cnc ballscrews in that machine!
