TMC Config does not seam to match register #4

Open Cncninja opened 3 years ago

Cncninja commented 3 years ago

I have a skr1.4 turbo LPC1769 board running the latest build as of 10/31/21. I have TMC-2160 drivers installed. and jumpers in spi mode. IOsender auto recognizes them and added the Trimatic tab and I can see the driver status so everything seems to be configured corectly. in the LPC Grblhal build TMC5160 is defined.

The issue I have is the steppers are loud and choppy/vibrate. completely different from when I use them with other firmware. it appears that the Rsence and some other configurations are not being applied correctly. based on the TMC status screen also if i jog and re-poll the tmc's the settings seem to change I have attached the Grblhal trimatic build config and the TMC screen from IOsender. I don't see a few of the lines populated and the values seem off from what I see online for 5160's I think it has to do with the rsense value not showing. tmc config setings image Thank you for your help

TMC2160 and TMC5160 has the same register structure?

R_SENSE is the same as Marlin(?), 75 milliohm = 0.075 ohm.

Humm, then I'm not sure what's wrong, do the values look correct?

Assuming the 5160 and 2160 register layouts are the same:

do the values look correct?

I believe so.

Have you tried to set the hybrid threshold with M913? It can also be compiled in by changing PWM_THRESHOLD_VELOCITY in trinamic.h. Other parameters can be changed there as well.

Setting a higher motor currents helps? This is done by $-settings per axis.

Note that most of the default values in tmc5160.h is overridden by settings in trinamic.h and $-settings. The settings in tmc5160.h is mainly aimed at those who want to use the low level API directly.
