M569 for choosing stealth chop is not working
-
If I do send
M569 P0 S0 D3
via console, I get the error message:
Error: M569: Driver 0 does not support mode 'stealthChop'
But the docs clearly say that the DUET uses TMC2660 and lists TMC2660 as stealth chop capable. Am I missing something?
Im running the latest firmwares with a DUET + DUEX5:
Firmwarename: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Elektronik: Duet WiFi 1.02 or later + DueX5
Firmware Version: 2.02(RTOS) (2018-12-24b1)
WiFi Server Version: 1.22
Web Interface Version: 1.22.6 -
Stealth chop is for the TMC2224 drivers on the Duet Maestro.
The TMC2660 drivers on the Duet 2 do not have stealth chop capability.
-
ah, thx for clarifying. Then, the docu is a bit misleading
Dnn (firmware 2.0 and later, only applies to TMC2660 and TMC22xx stepper drivers) Driver mode: 0=constant off time, 1=random off time, 2=spread cycle, 3=stealthChop or stealthChop2. The default is spreadCycle for TMC2660 drivers and stealthChop2 for TMC22xx. In stealthChop mode the drivers will switch over to spreadCycle automatically at high speeds, see the V parameter.
-
I updated the docs to clarify that mode 3 only applies to the TMC22xx drivers.

@nhof OK, 22xx is not 2208 with external adapte, so I think no support for 2208
Thank you

Duet Maestro supports two external TMC2208 or TMC2224 drivers. Duet WiFi and Ethernet only support TMC2660 and dumb step/direction/enable drivers.

Ok, thank you, but is strange, to much over extrusion with defaults settings.

Are the microstepping jumpers set correctly for x16 ? Have you set the correct steps/mm ?
-
Ohh, you are right, maybe my jumpers, three inserted and I now think only two are needed for TMC2208, I will check.
Thank you.
