If visualizing the machine orthoganal to the X-axis/staring down the Y-axis I have 5mm of drift from right-to-left-front-to-back (wrt the center of the Y-plate smack dab in the middle of the X-axis). This is over 2580mm. Upon returning to home, it ends up right where it started. My machine is square (ish) and I just want to see if this drift is normal for others and why most have some sort of routed or tacked-on wheel track. All printed parts ordered from V1. I can upload pictures later if needed - or do you all think this is normal drift and I should just route in some tracks?
I also have a weird issue with the right Y-stepper. I jog forward (y) any distance and park the axis for 10s or longer and when trying to jog back it sounds like the stepper on the right is energizing for the very first time. This is not always an issue but sometimes it causes missed steps. I have yet to investigate what currents are making it to the steppers (using mini-rambo purchased from v1) and have not updated the firmware/eeprom to disable stepper timeout (although this shouldn’t be an issue at 10s). The belts are tensioned equally on each side. The pulleys are tensioned fine, not binding, and are in line with the toothed gear. The grub screws are tight. Any thoughts on how to track this issue down?
