Layer shift and jumping belts
Maybe I'm getting closer to the problem, or maybe not. During a print job, I heard a noise that sounded like the belt hitting the side wall. I then discovered that there is a teacher shift. This is not the first time this has happened and has happened before.
I can reproduce the error pattern by first starting a Y test, then an X test and then phase stepping. Basically, it's just that the head is far forward and to the left and it wants to move at that moment. After further testing, I also noticed that if I control the printer Auto Home and then manually and move X completely to the left and Y completely to the front, the error image also appears. For example, if I set Y to -9 and then X to -8 (i.e. XY fully extended), then I can also provoke a deflecting belt. Once this has happened, I can produce it again by going back to Auto Home.
Checked Motors
Checked the Belt tension already (84 HZ)
Reset the Firmware and installed the new 6.0.3
Has anyone experienced a similar phenomenon?I can't get any further with belt tuning.
