I'm getting layer shifting on the y axis. Sometimes it will do ~100 layers just fine, other times every 3rd layer or so seems to miss steps and get offset from the ones underneath it. I've checked the pulley lead screws are tight and the belt is properly tensioned. Do I need to adjust the stepper driver? How much and which way? The motor for the carriage seems underpowered.

Hello people, I was having terrible problems with temperatures fluctuations and my prints didn't start when using octoprint because the temperature was too unstable. Recently I found a simple fix using a 10v1000uf capacitor in the board 5v pins. Now take a look at my temps after this change: They are pretty stable!!! and finally started to print from octoprint. You can do this really quick and for cheap, I found this information in the following video (method 2): https://www.youtube.com/watch?v=qCtL0Yd_w0I I hope this helps people from the thread "Printing stops" and others reporting different issues.
Trimpot adjustment to send more power to the Y-Axis (Hotend Axis) should solve the issue if you think it's under powered. Whilst powered off you can remove the stepper and turn the trimpot clockwise slightly to increase the current being sent tot that motor.
Also check that the carriage wheels are not clamped onto the beam too tightly.
I've done both these things, I'm still having the same problem though. Any other ideas?
I think the motor driver was messed up and may have led to damage to the stepper motor. I've ordered replacements and will update when possible
@Makertech, The problem got progressively worse until the axis quit moving all together. The machine won't even home now. I've replaced both the motor and the driver and nothing has changed. I checked the wiring and connections. What should I look at next, I'm getting upset that I paid so much and have had it for so long and I still can't get it working. I've put money into it after purchasing just for the problems to stack up to uselessness. I may need a new electronics board... would that be the likely issue at this point? If so, how should I REQUEST a replacement? At this point I shouldn't have to pay for more replacement parts
