I’m concerned that I am wearing out my welcome, but here goes again.
I’ve read and re-read the instructions and posts here on how tight the delrin wheels should be. On the X axis, all seems to be well. But, on the Y, I seem to have a problem. I am setting the wheels so that I can barely turn them by hand. I make sure that I lift up a bit on the X gantry to take all the weight off them so that I know that the amount of tightness is all based on the position of the off-centre nuts.
When I first set the machine up, I am guessing that one side was too tight, as the machine pulled the X gantry out of square, then stalled. I removed the drive screws, re-set everything, and managed to get a small project completed.
I am still concerned that the wheels are a bit tight, judging only by the sound of the Y axis movement, so I tried slacking them off a bit, but when I did this, the bottom wheels hit the two centre mounting feet.
Is there some magic to all this, or am I simply over complicating a simple issue?
