Plus side, I do have enough spare 2130s to do the same on my resurrected da vinci! So there is a positive!

which voltage has your printer?
12V or 24V?

the tmc2130 doesn't work well with 12V

Works fine with 12V. Just need to tune it properly.

so i accidentally got some TMC2130s V1.0 for free (amazon screw-up) and also had bought a GT2560 Geeetech board and FML man, what a pain this drivers are...am coming from a CR10S swapping the old board for this one (I probable regret doing it now) but I like to tinker with stuff but clearly went over my head on this one...I mean i dont mind the soldering and electronics but for the love of god why would anyone put pinouts on a board that dont go anywhere electronically?? I thought this was mostly plug and play into the socket, what a fool I was....
anyways, am going to follow toms video and try one driver at least and see how far i go....
does anyone know if getting 0.9 step motors is a worth move from 1.8 step motors? my goal is silent n faster printing...

First as you are saying you got TMC2130v1.0 I assume you have either Fysetc ones. I they would have at least cloned it 1:1 from the original watterott desing would have prevented my a lot of headache getting People to explain what is the issue with misconfigured CFG solder bridged, missing thermal breaktrough and so on.
Concerning a Change from 1.8° to 0.9° stepper Motors, this is in the first place not a question of the TMC Drivers ist a question of your underlying Hardware and Firmware. On a 8bit board with 0.9° stepper Motors and usual 16 teeth GT2 belts your limiting yourself in Terms of printspeed / steprates quite fast.
At 80mm/s will be the theoretical Maximum you will be able to run without the Firmware falling into dual or quad stepping. So Either think of a 32bit board or a splitted Hardware Firmware solution like klippe Firmware where the heavy load runs on a RPi and the Controller only doing the step pulsing

Hi Dave,

The 2130s don't seem to be too quiet if you tell them to go 10mm. I thought I'd done something wrong when I first installed them. They are much quieter when actually printing. Also, bring the current down as much as you can.

Oh hi Stefan,
I apparently didn't get a notification for this reply of yours! You're right: the drivers are a lot quieter when doing regular print moves. I'll tune the currents today or tomorrow and see how low I can go before the motors skip etc.
What current do you run your drivers at?

Hi Dave,

My drivers are set pretty low: 650mA.

Hi Stefan, thanks!
I'll try that out. Now they're 700 but let's see what happens with 50 less :-)
Do you use 650 on the Z as well?

Hi Dave,

I still use an A4988 on z. Just converted x & y.

Hi Stefan,
OK! A new, weird issue that I need to investigate the next days: First, my steps per mm on the Z were half the amount that they needed to be, which caused my first 2 test prints to fail after a few layers (obviously I noticed something was wrong and stopped the machine).
After I then doubled the amount of steps, now I start the print, it extrudes a bit, everything like always, homing works and stuff, but then the move that would bring the extruder to the center on the bed and "down" to the bed, somehow makes the Z motors do a loud noise, they don't rotate and then it starts the print basically 10mm above the bed.
Retried a few times, always the same issue.
Also, the LCD sometimes shows gibberish but I don't think this is related.
