Hey guys. About a month ago i was finally able to get my printer to a good working state - or so i thought. I started printing smaller things without issue, now I’m beginning to push the boundaries a bit and print bigger. The issue is, I’m starting to get later shifting. The shifts always occur in the Y axis, where I’m using a Nema 23 geared down with a 3:1 reduction, which drives a shaft and two g2 belts to slide a gantry (I can post photos if needed).
At first, I thought this was a mechanical issue. My print head sits very close to the build plate (only a couple mm higher than the lowest tip of the nozzle), so I thought some portion may be catching, but the Nema 23 is pretty tough, and I have to apply quite a bit of force to cause the gantry to shift (and even when I do that, the belts slip before the motor skips).
Most recently, I’ve decided that maybe the motor is getting too hot and is not behaving optimally, but I can’t imagine it’s getting that hot without causing any damage or permanent flex to the ABS mount it’s bolted to. Plus, I’m only running it at 1000 - 1200 mA (the motor is rated for 2 or 3 amp max, I believe). I would increase the current, but as I’ve said already, the belts slip before the motor stalls, so I don’t think adding MORE torque would really do anything.
Does anyone have any ideas? I’m lost and it’s starting to get frustrating because all I want to do is print big! Haha.
Thank you in advanced for any and all help (and I apologize for the super long write up)

Got it! My machine is now running 3.0. I had to revert back to 1.19, but the second time around I was able to successfully update everything. Time to update my config file and start playing around. Love the new WebControl design, btw!

Thank you everyone for your help!
