Prusa Mini+ X-axis test is failing
I have just finished my assembly of my Prusa Mini+. The guidelines were extremely clear and well organized, really well done! Thank you for that!
Though, during my first calibration run I get a failure on the X-axis.
I did some research on the forums and I checked the following already:
- The belt on the X-axis is not too tense. I did several runs with varying stiffness, no difference.
- I cannot see any wires between the print head and the Z-axis.
- There is enough slack on the wires leading to the print head. The head can reach all the way to the end.
- I hear a small 'tud' when the print head reaches the beginning of the X-axis (touching the Z-axis) and the far-end of the X-axis. But I assume that is normal. It does not sound strange or out of place, at least.
- It looks like the X-axis is straight and in-line, like it's supposed to be.
What I see happening when the test is running:
- The print-head moves three times from the start to the far-end.
- Every cycle I hear the motor speeding up a bit, I think that is intended and part of the test cycle.
- After the third run, when the print head reaches the beginning again, the error is shown.
What else can I do to try and troubleshoot this issue?
OK, I think I found the problem. I disassembled the print head again and I think the drive build was not inserted far enough.Maybe the length was a bit too long, for the test to succeed.
The X-axis test succeeds now! But now the Z-axis test fails! 🤡
Time for some more troubleshooting then
OK, Z-axis is also succeeding now. I had the same issue as here: https://forum.prusaprinters.org/forum/assembly-and-first-prints-troubleshooting/prusa-mini-calibration-z-axis-fail/
(Some bolts fixed too hard)
