Controller Board

6x CNC Controller v1.2

Machine Description

Gantry router XYZY, hardwired to DRV8825 drivers on Nema17s. Proximity end stops and a Makita r700 router.
Just temp testing before I commit to larger motors and drivers. The cnc is currently working on a Mega5x GRBL in the same config.

Grbl 3.7 [FluidNC v3.7.17 (wifi) '$' for help]

User Interface Software

WebUI and FluidTerm

What happened?

I started with the 6x_xyyz_pwm.yaml config example, battled for some time to get the end stops to function correctly, but got that sorted. I then proceeded to connect the drivers so I could test movement and ultimately a homing run but this is when I hit a wall.
I was not able to get the motors enabled or moving - they are getting signal as they do lock up but they are not moving at all.
Nor does any of the motor LEDs light up when I jog X or send a movement and other commands: $ME, $MD, G0 X10, G28

This is my first attempt at fluidnc and a config file, so when I couldn't get it to move I uploaded the default 6x_default.yaml file renamed it to config.yaml and rebooted, thinking it might be some config I have wrong. I tried the IO_test.nc file with the drivers disconnected (didn't want my dual Y to cause issues if they move wrong) but the same result. I see the io4, 12, 14 and 15 LEDs light up but none of the motor ones.

Debug output:
[MSG:INFO: GCode Comment...IO Test Begin]

[MSG:/sd/io_test.nc file job succeeded]

I've added my initial config.yaml - the one currently on the board is the 6x_default.yaml renamed.
I'm confident I've not messed up the wiring, as it works fine when I hook the mega back up.

Are you sure you are using the correct config file.

It says config.yaml, but you mentioned a different one.

Be careful with those stepstick drivers. The controller was not designed for them and any miswire can break the I2SO chips.

The disable pins are not correct. See this and send a photo of your setup

I'm sure about the config file - renamed it from original example files on git.
Wiring: I just connected ena, stp, dir and neg to the stepstics - the rest I wire directly from powersupply and then to the steppers.

As for the disable pin, my initial config file was using a shared pin: I2SO.0 - which is motor1's in the example config files.
I tried the 6x_default.yaml file which I renamed to config.yaml which still uses the individual disable pins, still no joy.
I'll take a picture of the setup when I can.
