Hi Andrea, right now I'm on the TMC2208's in the original Motherboard (GT2560 V3.0) They use R110-type current sensing resistors (0.11 Ohm ): - 1A-drives: 8*1 A *0.11 Ohm = 0.88 V - 1.68A-drive: 8*1.68 A *0.11 Ohm = 1.48 V and I don't see issues yet. But I really only did some test-prints for calibr...

Okay guys, I'm back... :roll: I ended up not changing the voltage on the standard A4988's yet, even though some of the steppers got really hot and sometimes I had repeatable step-skipping on SOME prints. I had to keep the printer close around me, as there were quite a lot of fails - especially with ...

Hi, I'm new to 3D-printing and bought myself an A20M some weeks ago. Today I wanted to tune the stepper drivers, but I got a little confused by this thread as my voltage settings should apparently be totally different. Supply voltage is supposed to be 5 V. It uses the A4988ET chips, so I Max Driver ...
