Re: Dolly MK52 upgrade

Yeah - I saw that - but there are not really a lot of choices out there. Unfortunately, prusa3d MK2.5 upgrade for $199 is not available until later December as of today?

Re: Dolly MK52 upgrade

MrBoub - thanks for the answer - about the TMCs - I could not cool them down even with a 80mm fan and low current stetting around 600mA(x/y) and 800(z) - they were always giving me temperature errors and I lost quite a few prints. Lower current setting would let the steppers stall - From what I was ...

Dolly MK52 upgrade

Hi Guy's, quick - "or not so quick" - question - I build the "dolly" clone and was thinking of upgrading to a MK52 + spring steel sheet. Here are a few questions: My clone is exactly Tom's dolly clone - Ramps1.4, A4988 drivers (X,Y,Z (single driver for 2 motors), etc.) (I was upgrading to the TMC213...

Re: Dolly: Problems printing PETG

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.

Re: Dolly: Problems printing PETG

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

DOLLY: TMC2130 Upgrade and Z_PROBE?

In the youtube video Tom is connecting the Z driver to the Z_MIN_ENDSTOP where the Z_PROBE used to be - does that make sense at all? Shouldn't we rather still use the Z_PROBE for autobedleveling?
