Bear Bondtech X-Axis won't calibrate.
Forgive me if this isn't the correct place for this question, but seeing there were other questions about the Bear upgrade, I'm hoping to find some help. I installed the Bondtech upgrade to my full Bear upgrade some time ago. I had a couple parts that had cracked and the bearing were making noise so I reprinted everything and got it back together and printing. But because I change things on all 3 axis, I wanted to run through the calibration again. I know special firmware is needed because of differences in the sizes to the original parts, and I had done it in the past. Only this time, I cannot get it to pass the X-Axis calibration. I have tried several different versions of firmware that are suppose to have the changes needed, but they all fail on the X-Axis. I have checked and double checked that there is nothing interfering with the X-Axis movement. I'm not sure what to do next to get the printer working again.
