Crashes : X vs Y and internal enclosure spool holder
I just put my printer in an enclosure (the prusa box). I installed the internal spool holder, which does a U-turn of the filament in a teflon tube (see image at the end)
I noticed that I had a significant amount of Y crashes reported by the printer. I inspected the Y axis carefully, did self tests, checked belt tension : everything seemed fine.
In a specific print that was causing more of these crashes, I watched carefully and could observe the events. It seems that when the extruder moves fast to the right (when jumping from one position to the other) the filament friction in the teflon tube is too high and causes the crash on the X axis. I'm 99% sure of this, it always happened when moving fast to the right and thus pulling too quick on the filament. This caused a few loud noises (belt jumping?) and at the exact same time Y axis crash counter increments, and the axes do they extents recalibration and print resumes.
1) Why is the system detecting this as a Y crash? It is definitely X
2) Is there any recommendation for these spool mounts with turns in a teflon tube? The turns are not sharp, and tube is not pinched, I inspected all. But there definitely is some friction in the tube.
Thanks!
RE: Crashes : X vs Y and internal enclosure spool holder
I don't have a Prusabox, so can't speak from any experience. Just from the picture this feels like an awkward placement of the spool. Certainly significant bend. I'd prefer feeding my Mk3's from the top in a straight line. Having said that, I'm feeding my Minis with a similarly bent tube with no issues, so I suspect this may not be the culprit. Maybe some obstruction on the x-axis?
