X-Axis Calibration Failed
I recently finished my MK3S+ kit and successfully printed the PRUSA logo. On my second print, the batman logo, there was an error during the print, and the print did not finish. It seemed like the extruder "got lost" in the X-axis direction. When I went to go re-calibrate, the X-axis calibration now fails. The extruder belt seems tight enough, and the extruder drive pulley is tight, also. What else can I check? I also did a factory reset. That did not fix the issue.

Do you mean it made a step?
Check your Motor roller is tight (both screws) or belt not jumping too loose or something caught in belt.
if you have checked for zip ties not hitting and ok, check Belt tension.
normal things like, Check cableing in einsy box.
did you align bearing during construction.
check backing plate has not been overtightened and pinching bearing as it gets warm from friction.
Check cables draging on x rails
Hope it helps

Congratulations on first print!
I would check to see if the X axis can move all the way left to home and all the way right without hitting anything, particularly the extruder wiring bundle hitting the frame or Einsy box.

RE: X-Axis Calibration Failed
Yes, the extruder can move all the way to the left and to the right without hitting anything. I noticed early during the very first calibration that the extruder cable comes very close to the Einsy box. What happens when the X-axis calibration fails is the extruder is in the middle and it will move to the left about an inch and then to the right about an inch and then to the left about an inch. At that point the X-axis calibration fails. The extruder does not even come close to moving the entire range.
RE: X-Axis Calibration Failed
Does the X axis move smoothly in both directions when moved by hand, with the printer in Idle State, or switched off!
sometimes the linear bearings jam on something!
Did you lubricate the linear bearings during assembly?
If not, NOW might be a good time!

RE: X-Axis Calibration Failed
Well, the extruder moves as smoothly as it did during the first successful print. I did not lubricate the bearings because the instructions said it was not necessary during the build of the kit. That being said, I will lubricate the bearings and see if that fixes the issue. Thanks.
RE: X-Axis Calibration Failed
You may find lubrication helps...
It's the simplest possibility barring zip tie collision. at the ends of travel, which is unlikely to be the issue here

Thanks for all the input. Lots of things to check.

Hi;
I found that On mine the Belt was initially to tight on the X-axis, and had failures, what is the current tension on your belts when you check it on ? the menu (LCD Menu --> Support --> Belt Status)
I found that if mine where between 260-275 seemed to have been the sweet spot.
One of the other issues for crashes was due to first layer issues where if a part slightly curled up the pinda would hit it and register a crash
