Perfect! Thanks - I may experiment with the quieter option. My wife will approve.

Sorry, my confusion is showing. I have the original red RAMPS 1.4 board with the driver modules embedded. If I'm going to get the BIGTREETECH SKR 1.4, the site gives me those options listed above for the different driver modules to include. So my question boils down to: which of those listed driver ...

Ah - understood. The hardware driver module attached to the board is not linked to a specific stepper motor. I was coming at this from a computer angle where the software driver must match the hardware or things don't work. Which is true in this case, but I get to pick the hardware driver side when ...

How do I know which stepper driver is correct for the default motors? Looking at Configuration_adv.h, I don't have the TMC26X enabled, so is it the A4988? I do find references throughout the code to the TMC26xx. I suppose I need to learn a little more about my specific setup.

Thanks guys - I should have noticed the wiring from the power supply. Seems weird that it hasn't been a major problem to date, although I guess I WAS pushing several prints through back-to-back for some Mom presents. Usually I start a print mid-afternoon and it finishes overnight, then the printer h...

My trusty 3DP-12 finally had a meltdown on the control board. I hit a thermal runaway error, and while diagnosing why the hotend fan was dead, I found that the power supply wire into the control board was completely melted through (see the picture). Everything is original(!) and it's been running fi...
