Cannot reach max current (TMC2209) #14

Open paukstelis opened 3 weeks ago

paukstelis commented 3 weeks ago

In older builds I could set the max run current for TCM2209 ([PLUGIN:Trinamic v0.16]) to 2000 mA:

Send: M122

Recv:                       X       Z       A       B

With latest version, I can only set max current up to a certain point. That point is dependent on the hold current. If I set hold current to 100%, then I can get current up to 1767, at which point I can decrease the hold current again. If I don't set that hold current to 100%, I start to get out-of-range errors earlier when trying to set run current.

This seems to still exist. I verified that I've pulled the latest.
