Collisions During First Solid Layers
Hi,
I'm having a problem with my 3D printer detecting a Y axis collision repeatedly during a print. I have many printers and they all have phantom collisions occasionally, but I'm farming this part right now and it's always happening at this z height on this printer with this file. This specific height is when it's printing the first layer of solid infill/the first top shell layer. It detects a collision with the sparse infill when it's bridging over it.
It's ALWAYS a Y axis collision and happens several times on the same layer. The same file and same filament prints fine on other printers.
It seems like this could be caused by worn out bearing and rod. It could also be the motor overheating. It could be overextruding or the speed could be too high, but that seems a little less likely given that the gcode prints fine on other printers.
Replacing the motor or the bearings and rods requires tearing down the printer and rebuilding it and changing the slicer settings for this printer requires slicing differently for this one printer than the 5 others, so none of these solutions are easy. Is there any way to tell which of these solutions is likely to work so I know which I should pursue first?
My immediate next steps are testing different files to see if they always stop at the same z height or at whichever height the infill changes to solid and cleaning the rod and applying new grease.
