TMC5160

[boucz]

Hi
Is the bug with grbl-esp32 and TMC5160 still present in FluidNC? I would like to use stealthchop but with higher Amps than allowed with TMC2130. (I do not have the drivers for now)
Thanks !

[bdring]

I assume so, but there may be few things we could try to fix it in FluidNC. I could create a test branch with the changes, but there is no guarantee it will be fixed.

[boucz]

Ok, a friend will let me play with his 3d printer drivers. I will try to run some tests this we :)

[bdring]

OK, test the main branch first. Run some gcode through a full range of current levels.

I will create a new branch for you to compare it with. That will take a day or 2.

[bdring]

I think it is fixed. Try the Trinamic branch.

[boucz]

I just try the trinamic branch and the bug is still here (running 1A, holding 0.75A) using coolstep as well as stealthchop mode.

What is happening exactly.

[boucz]

Motors (random position) stops working but the gcode continue.
First time it was the x axes, the second time with lower current the y axis stops when running the same gcode (spindle running without bit speed and acceleration very conservative)

[bdring]

It might be a problem we cannot fix in firmware.

[boucz]

maybe, i'll run it with my tmc2130 to be sure.

[atlaste]

Can you please double and triple-check that you have the right branch? https://github.com/bdring/FluidNC/tree/Trinamic is the right one, not to be confused with the TMCsomething branch. You can spot it in the TrinamicSPI class with all the if's if you look for 5160 and 2130. The boot message of Fluidnc should also dump the version with the git tag.

[bdring]

FWIW: It has been pushed to main already.

[boucz]

Ok, you were right, I did swap the TMC5160 with another (thanks for 3d printer to have so much drivers :)) and no more problems.
Did another test using the faulty driver on another axe and I had the same problem on this axe.
with "good" drivers, I've been able to run 3 gcodes without problem.
Even tried last Devt from this night without problem, it seems that the problem is gone :)
thanks a lot !

Great. Thanks for the help and patience as we iron out the wrinkles in beta mode. Here is a link to our Discord server.
