Question about Duet2Maestro external drive module

How to bypass uart and connect high current driver
-
You could try picking up the step and direction signals from the connector for the 2-driver daughter board. The signal levels are 3.3V.

Hello, if I don’t use the onboard TMC2224, but use STEP and DIR on the board to connect 5 external drives, what should I do?
Thank you -
@Veti said in Question about Duet2Maestro external drive module:
the duet maestro does not support the 2209.
only the 2224.And the 2208, which is the same as the 2224 with a different pinout. It may be possible to get TMC2209 drivers working too, but stall detection would not be available.

The maximum number of STEP and DIR signal pairs you can pick up is 2.

If this is the case with an external drive module, how do I set it up?
Sorry for my bad English, translation software used -
You will need to common the grounds too.
We've never tried using external drivers with the Duet Maestro, but if it works at all, I don't think it will need any setting up apart from the usual steps/mm with M92.

Excuse me
E2 and E3 external drive modules can work, but X_Y_Z_E0_E1 external drive modules cannot work.
Please help me -

what do you mean by that? you want to replace the internal drivers?
-
I want to replace the TMC2224 on the motherboard with other drive modules
-
you want to desolder the onboard drivers?
at that stage it might be easier to get a skr board and run the lpc port of rrf on it
-
@Veti I don't know, can you tell me?
-
-
@Veti Thank you my friend
-
-
why would you want to use a drv8825 instead of a tmc driver?
-
@Veti I want to use a big drive to drive a big motor, not just DRV8825
-
the duet 3 can drive up to 6.3A
-
The price of DUET3 is beyond my ability.
I like DUET2MAESTRO very much, but TMC2224 is not what I want, I want more flexible drive support -
it makes no sense to buy a maestro and replace the drivers.
one of these ports with the port makes more sense.
