Fysetc TMC 2130 v1.0 in standalone/stealthchop mode on RAMPS 1.4?
Hi all, Just a simple question really. I've built my 3D printer with A4988 drivers on a RAMPS 1.4 board but would like to make my X and Y axes a little quieter, so I spotted some v1.0 Fysetc TMC 2130...

Are you mixing up TMC2100 and TMC2130 infos? AFAIK the 2130 is configured by SPI and the 2100 relies on cfg pin config.

My experience with TMC2100 is: stealthchop isn't suited for 3d printing, better use spreadcycle. It's still way more silent than A4988 ( 24V PSU recommended )

I want to change from the good old noisy A4988 to the supposedly quieter MKS LV8729. So I disconnected my steppers, replaced the stepper drivers, set vref/current, connected the steppers again,...

I have similar LV8728MR drivers and I have to invert the enable signal in firmware. Maybe that's also the case for your drivers?

That seems to have done the trick. They work fine now, although not quite as silent as I have hoped, even with 1/128 microstepping. Still a major improvement compared to the A4988s. Thank you!

Just some additional info, since this is the first result when googling this driver: You may have to invert the enable pin signal if you are switching from A4988s, at least that's what I had to do to...

Interesting, that the Vref potmeter still has a meaning, although you've set the current by SPI in FW. I guess SPI wasn't connected?
