Frustrating: Check X Axis Length Error  

Frustrating: Check X Axis Length Error

Hi All!

I know this topic has been hashed and rehashed many times and believe me I have read all of the posts and followed some of the advice that worked for others including breaking down the extruder assembly and reassembling, carefully rerunning the wires and placement of the zip ties. I even replaced the X axis rods and bearings. The extruder glides like it is on ice,sans belt. Unfortunately, none of that has fixed my problem and I am tending to think it may be hardware related; this is where I could really use some insight from the experts here on what pieces of HW could also throw off the "check x axis length" message or other things to try.

During a self test the x axis does move back and forth but not the full length without stopping on the error message.

Additionally, this all began when the filament that was fed from the dryer box became tangled and pulled the box off of the shelf, which is slightly higher and to the left side of the printer. When I walked into the room where I do my printing, I found the dryer box on the ground and the printer stopped on the error mentioned. Visually I could see no damage or scuffing on the printer or the box, so I am not sure that the printer was hit, but at some point there had to be significant tension on the x access bars and gears as the extruder attempted to continue pulling filament until it crashed.

Additionally, I have tried a belt test which moves back and forth but fails on the same error. I have also tried to test the filament sensor and it too fails.

I am really feeling out of options and could use the help of the experts here in trying to fix my printer. Other tests? Parts? Steps?

Many thanks in advance for your time in reading this.

Best Regards,

Mike
