(This topic disappears right after I submit. Just trying again)
Just finished the build and run some tests to check if axies move properly. But steppers start creating a high pitch noise and locks down. There I saw several posts regarding this issue but none of them is with the Ramps configuration. Let me summarize the issue:
Those alligator clips might not be passing high current from the power supply very well. Current draw from the motors could cause voltage drop, which if it is low enough causes the arduino to lose its mind.
Check the voltage on the ramps side when the condition occurs, or just wire it better and see if it fixes it.
Maybe it’s just an optical illusion from your camera but from the top down pic of your machine the bottom right corner looks way out of square. If it’s truly that out of whack it wouldn’t surprise me that your motors get them selves into a bind.
I noticed that too, but earlier in this post he says he’s able to move both both x and y so I chalked it up to an optical illusion. It’s when he runs any 3rd axis (after moving the other 2) that the lockup occurs, is my understanding.
Yikes that's not good. Practically, running excessively high current can push the stepper drivers into thermal shutdown, which can be catastrophic if you are running a powerful tool.
Go through the steps to set your motor current properly.
