X-Axis motor calibration issue - pulley loose
Similar to a question already posted, but the answer did not help my situation:
I recently finished putting my kit together and ran through the self-test on 3.0.9. I had to make an adjustment to the X-Axis motor/belt. Initially the motor would make a kind of loud "surging" sound and the printhead carriage would not move. I turned the unit off and tried moving the carriage along the X-Axis with my hand, but it was locked tight and would not move. The belt was very tight from when I assembled it. I experimented with loosening the belt and eventually got it to a point where I could manually move the carriage. At this point the self test passed.
Tonight I was going to move on to calibration, but decided to upgrade firmware to 3.0.10 and re-run the self test to be sure. After doing so, the test is now failing again on the X-Axis test, this time on the "pulley loose" condition. I tried tightening the belt a bit again, but even tightening it by just a single "tooth" gets me back to a point where the carriage won't move again. Is there something other than the belt tightness I need to be looking at? Looking for some suggestions on how to proceed.
Is this a good question?
