Hi,
I'm trying to print PETG (eSun) on my Dolly using 245C/60C - Towards the end of the print it seems the filament starts curling up when working on the rectangular columns (ref Fusion 360 view) - Does anyone know why this is happening?

btw/ I upgraded the hotend to a E3D All-metal v6 HotEnd (the cheap China version broke) and upgraded the motor drivers to TMC2130 drivers.

I'm just looking more carefully at the printed part and it looks the hotend is smashed into the part - maybe a Slir3r problem??

Slow down the print by requiring a minimum layer time?

I found the problem - the TMC2130 driver of the Z-Axis was bad - I replaced it with initial A4988 driver and now it prints fine.
