Did you put loctite on the grub screws??
If you put your belt too tight and the screw cant get into the lock nut and only in the plastic can cause this. I had it happen on my X axis.
Probably this one. Hang a bell from the bottom of the gantry like the Harley guys do from their bikes LOL
looks around to make sure Ryan isn’t listening … I might have forgotten to Loctited the Y axis 
When it loosens, the belt is pretty floppy. I have been tightening it only to the point where it doesn’t flop around, but not so much that it makes a sound when plucked. I am going to reprint the adjustable belt holder for that side today. The non-rail belt has not budged, so it’s likely the print.
As if the machine doesn’t make enough noise as it is! 
LOL It happens! Easy enough to add and worth it for sure!
Hopefully I explained myself ok in the first post. Is the screw able to get into the block enough to get to the M5 lock nut inside? There is a locknut inside correct?? If both of those are a yes then the belt shouldn’t be getting any looser than how you set it.
LOL
I would double check your wire connection to the far stepper. Sounds like it is a bad connection.
Yes, both of those are true. But I think I saw somewhere else on the forum that it could just be that it printed with a slot that’s a little too big so the belt slips a little. I can’t count how many times I’ve removed and reinstalled it, so that obviously isn’t helping.
that is very possible
I don’t know if this is actually relevant, and I think you already knew… As a new user of the Jackpot, some stray trailing spaces in my config.yaml file on one of the drivers section, caused the Z1 stepper to move faster than the Z2 stepper.
I have been following that thread. I’ll add checking the config file to my list. The only counter to that is that I’ve been completing cuts without problems until recently, which would suggest that the config is ok.
Status update: not finished with my whole checklist, so the LowRider is still on the bench.
Next up:
WAIT, we are supposed to do that? I need to recheck the guide. I did NOT Do that 
looks like I have some work ahead of me
I would double check this… this type of code can be frustrating especially if you aren’t in “coding” mode
Definitely a recommended step. The X and Y steppers are a bit of a pain to get at after everything is assembled, but it’s not as bad as it seems.
I am in coding mode most days for my job (often Python, sometimes Node.js). I strongly dislike YAML, specifically for how finicky it is with empty spaces.
Thread locker is not required but really advisable. Grub screws having gotten loose are the cause of issues way more than you might expect…
I used blue Loctite on anything that was metal to metal (not on Nylon nuts). I wasn’t taking any chances.
It requires a special applicator, but I hear that the white loctite is really good…
Idk if we are talking about special applicators I hear brown is better

I don’t even know what that is… 
Back on the ground!
Starting an air cut was successful - no weird skewing due to mismatched motor movements. I didn’t have time to try an actual cut, but I’m ready for it.
Also, I found the belt issue:
The Y min end loop had slipped inside the holder. I replaced the holder and stuck the cut end of a zip tie in the loop, which should keep the belt from slipping into its holder again.
I did encounter a new weird issue. When WLED powers up, the brightness starts cycling from low to high on repeat. I can change the brightness manually, but it goes right back to cycling. I can’t find a setting to explain why it’s doing that, so I’ll have to dig into the documentation to see if I can find something there. This behavior was not present before I put the gantry up on the workbench a few days ago. Odd.
Edit: a thought occurred to me. I set up some buttons with presets on the short press and double press. Perhaps it has to do with that.
Very possible.
Mine are doing crazy things every once in a while but I’m pretty sure its because I never went back and added the extra ground that Ryan said is needed. Was too ready to get it running LOL
I have, at least, done this. I’ll rearrange the button presets and see what happens.
Rearranging the button settings worked. I put the three presets I want all on one button and disabled the other. I thought I was going to use more than three, but changed my mind.
