connecting external stepper driver (MKS TB6600)
-
Hello,
I want to connect an external stepper driver via the duet 2 wifi expansion slot... I've read a few threads and the dozuki page, and I just want to make sure I understood how to do it before I do it !You can find the pin layout of the MKS TB6600 on this page
Here is how I would do it right now, but I'm very not shure !
To run the Z axis from the E2 pins on the expansion board, I would need to connect :
E2_EN to EN
E2_DIR to DIR
E2_STEP to CLK
E2_STOP to GNDAfter connecing everything I would need to use the M584 commande to remap the Z driver (currently number 2) to driver number 5 (E2 driver)
I hope this is it, but if not, do you have any advice ?
Thanks a lot

OK,
So I tried it and... didn't work ! Was to be expected I guess.
Trying to find a solution ! -
I'm doing that for testing at the moment. I believe that the outputs of the logic board are 3.3v and the tb6600 needs 5v so I'm using the breakout daughter board for level shifting. I also believe the tb6600 enable pins work enabled low so you might want to disconnect the enabled pins and see if it works. I believe that the breakout board inverts the logic output so that may be why my setup works...

ok, found the solution, tried with enabled pin in and out didn't work, but tried something rather simple after seeing this dozuki page ( I don't know how I missed it before ! )... rather than connecting the TB6600 GND to the E2_STOP, I connected it directly to the GND on pin number 2... works perfectly now !
so the correct pin layout for me was :
E2_EN to EN
E2_DIR to DIR
E2_STEP to CLK
GND to GNDand for the mode selection on the TB6600 :
M1 ON
M2 ON
M3 OFF
TQ OFF ( AUTO )I'm so happy this finally works !
<Thanks @CNCModeller
