M569 settings not work with external driver(tmc2208)

seraser

Hi.

I have a ramps board adapted to duet because for only one driver for dual extrusion do not need a expansion board.

The problem is I cant set values for stealchop in P5 see:

In config.g

M569 P5 S1 R0 D3 ; E1 Drive 5 goes forwards

Console output after reboot

M569 P5: Drive 5 runs forwards, active low enable, step timing fast

Parameter Dnnn do not take effect

Tmc2208 work but with bad condition to much over extrusion and I want set other parameters.

Firmware 2.04RC3

Thank you.

If I understand your question correctly...

This external TMC2208, what wires are connected from the Duet? Power? Step/Dir? Anything else?

Setting any internal registers in a TMCxxxx driver requires either SPI or serial UART. Duet uses SPI. Is SPI connect from the Duet to the external TMC2208? If not, then those parameters will never work.

@Danal

Yes, step, dir and enable.

So thank you, I think I cant connect via spi so no option to work.

Danal

No option to change defaults. You might wish to use a TMC that accepts jumpers for configuration, like the 2103, for an external.

Ok, I will order TMC2130, thank you.

That won't help, if it's a Duet WiFi or Ethernet then the only type of smart driver supported in the standard firmware build is TMC2660.

@dc42 Ok, no dual extrusion for me, arggg, because I have double Z in three printers with duetwifi.

Thank you.

External. From the Duet, only Step/Dir/Enable via the expansion port. All other options set by jumpers local to the external chip.

Obviously, can not use Duet config commands to set options.... other than that, it should work???

that is what the duex2 and duex5 is for.
