tool change motor only spins in 1 direction
-
I have a LDO 14:1 motor attached to the 10 CONN LCD port on my duet2. there are GND, 3.3V, DIR, STEP, and EN pin used. I did not connect the STOP pin.
on the external driver board, it is set to 4x microstep. and the current is 0.58A
when I home U axis, it will go to min just fine. however, that's the only direction it would go. even if I jog it +10 (any positive direction), it will turn the same amount of movement in the negative direction. jogging -10 would turn 10 in the negative direction as expected. I can't figure it out. Below is my config for the U axis.
M569 P10 S0 ; physical drive 10 CONN LCD #10 (tool changer)
M584 U10 ; set drive mapping U axis as CONN LCD #10 tool changer.
M92 U30.578
M566 U50
M203 u15000
M201 U800;current and microstep manually set on external stepper driver breakout board and A4988 driver to 1/4 microstepping and .580A
M208 U0:5000 ; axis limits
M574 U2 S1 "P^e0stop" ; config active high endstop for low/high on U via pin e0stop
-
perhaps it is a symptom of a bad connection on the DIR wire. i'll check when I get home.

Post full config.g please. Firmware version?

here it is. there is a lot that is still in the works so it might be a bit messy

Can you send M98 P"config.g" and report any errors?
Can you also send M584, M350, M92 by themselves and compare what they report with what you expect?
Also I note that you aren't defining most of the required values for U. M566, <203, M201, M906

@phaedrux
M66, M203,M201 are all defined for U
M906 and M350 are not because I am using the A4988 driver with an external board.m98 p"config.g"

I think you have a line wrap problem.

i was looking at that too and wonder whats going on as well. it doesnt seem to be related but ill have to look into it. i have physical drive 5 on the duex5 assigned as the extruder for tool 0 right now.
as for the tool change motor direction, it was a bad connection on the DIR wire. i swapped it out for a new one and all is fine.
thank you phaedrux!
