Here two pictures of the "Robust" version with extra powerful and hopefully cooler Extruder stepper and 4020 Fan. This is within my Qidi-Max Testmachine where I test if heater, fans etc. are working as they should before shipping.
If this extra Nm are required is up to you. At least it just "cut" ABS Filament on the BMG drive gear when I forgot to heat the hotend (so it def. was not able to move the ABS forward) without any clicking. But obviously if you do this you might simply destroy the plastic gears so don't try it - I had luck using a pretty "soft" ABS.
