Hey all,
I'm running a stock Prusa Mendel with a custom extruder, and my bushings keep loosening. They remain attached to the x-axis, however they no longer grip the smooth rod tightly.
I'm suspecting that this is due to the temperature of the heated bed (Printing ABS on Kapton so I'm heating the bed to 120 C) but I'm wondering if anyone else has seen similar issues.
My extruder barrel may be too short causing the x axis to get closer to the heated bed than in other setups... but short of switching to linear bearings (for which I've yet to find a good supplier in Canada) I may try using ABS bushings instead of PLA.
Has anyone else seen anything similar?
Many thanks!
Jesse
