Hi friends, is there A20T firmware with 3D touch and TMC2208 support?

Hi,we do not have the corresponding firmware, you can directly exchange the wire sequence as shown in the figure.

I would like to upgrade to TMC2208, but have BlTouch.

Are you saying that if we swap the wires it will be supported?

Do you know when we will have a firmware with TMC2208 and 3DTouch support?

Hi,the firmware has nothing to do with the driver, you can still use the firmware that supports 3Dtouch.

I have installed TMC2209 https://www.amazon.co.uk/dp/B082FBLH62/ ... _at_prodpg

I'm trying to tune the VREF and all I get is 4.88v. Potentiometer makes no difference on output.

I know it could be a defective product, but I would be surprised if 5 of them are defective.

Any suggestions on what might be the problem?

Hi,can't adjust the voltage?

Correct. I can't adjust the voltage.

My guess is that the VREF pin hasn't been wired correctly, I found someone else with the same problem.

They probably work fine, but I have no way to adjust them without the VREF pin working.

I'm going to return them and get a different brand.
