[BUG] Mega Pro very loud Z-Stepper

[CraftoHohenvels]

Bug Description

My Mega Pro's z-Stepper is really loud when this fw is installed. I can't tell what causes this exactly, but it is this fw for sure. (Before installing it it was silent and after flashing the original fw it is silent again)

Steps to Reproduce

1. Download the firmware
2. Flash the firmware using OctoPrint Firmware Flasher
3. Move the head on the z-Axis

Expected behavior: sound silent as before and after

Actual behavior: The steppers sound a lot louder

You link the TMC flavor of the firmware and compare against “original“... 🤔 Did you actually replaced the stepper drivers? And if yes, which drivers?

Honestly I have no idea how the original FW “sounds“, moved to different FW after 1 or 2 prints years ago, but at least I cannot remember any significant difference. My Mega P with factory drivers runs just fine with the non-TMC flavor.

My bad, I linked the wrong fw, it is actually the one without TMC. I corrected the link in the original message.

The printer itself is bone stock
