A toolpath that I have carved several times in the past will make the Y axis move a little bit at the time towards the front every step down creating a gradient on the back wall, I stop the carve and send the router to the XY I zeroed before and it has also moved to the front, I re-home the machine and then it goes to where it was originally zeroed in XY. I have tried everything from updating to the latest Gsender, changing speed and acceleration to the Longboard settings, re assembling the X and Y lead screws making sure every coupler is tight, marking the couplers and motor shafts to see if there is movement, I replaced the anti-backlash nuts on the Y axis too. I have tune the machine following every tutorial and video there is, every part, it is still doing the same.
The carve is the back of a guitar neck placed along the X axis, making several back to the front movements of about 3 inches going back and forth on the Y axis, so I also decreased the speed and stepover and it is still doing the same, I did not have this issue before, now I have the SLB but that could be just a coincidence.
I switched to the SLB mostly due to homing issues with the regular Long board, the SLB was sent as a replacement. Everything is great with the SLB however, it’s been almost 2 weeks that I have not been able to resolve this issue, I’ve been exchanging e-mails with Jason from Sienci and most of the fixes I tried are the ones he recommended, I also posted in the Facebook group. There is a little bit of a sound on the X axis when coming to a stop or when starting the movement, it almost goes away when tightening the anti-backlash nut but if it’s too tight it starts wobbling the X lead screw so I ordered new nuts for the X and Z, of course they made it to the US with UPS quickly but now the went back to Canada for whatever reason. However that is on the X axis which, other than that sound, it feels properly tensioned and tight, so I don’t know if replacing the X anti-backlash will do anything since the issue is on the Y. Also I found weird that both sides of the Y axis are even and squared after they lost zero moving towards the front, which now makes me think it could somehow be the X axis or a software or firmware issue with the SLB, other option was Fusion somehow changed and it’s pushing the Longmill to its limits, I updated Fusion, lowered the speeds and stepover, still doing the same.
Any help is appreciated!

I’ve moved your post to a category where it will get more attention.
