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

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?

[William]

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?

[Bobertino]

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.
