6 pack built in esp, motors don't move

[Kevycnc]

I have a 6 pack controller that I have gone over the wiring multiple times. Had a friend also look at it. to confirm. I seem to have everything hooked up correctly. I can Enable and disable the motors with commands. However if I try to jog any, they all lock up and of course nothing moves. This was purchased on Tindie order 442504. Hoping I can get assistance with the correct config to start.

One other weird thing I noticed on the board. I have 3 axis wired up. But for some reason the ENA led on what would be Motor 5 (Ena I2SO.16 from the pinout on the wiki) is always lit when the controller is powered on.

Thanks.

I do suspect most of its because of my config file as I have struggled with it and tried a few while making changes to suit. I see one alarm mentioned at the end. I try to clear prior to jogging. Should note I currently have no limit switches set up.

• What stepper motor drivers are you using?
• How are your jumper configured?

If you only use i2so numbers less than 16 the controller is not actively setting the higher i2so number values.

[Kevycnc]

HI, the stepper drivers are DM556T for Y axis, DM542T for X and Z axis. I am unclear what you mean about the jumper configuration. I will attach some pictures. Edit: I did try unhooking the ENA signal as some suggested, but then the Motor enable and disable commands stopped working, so I put it back for now.

[bdring]

That is not technically a 6 Pack. It is a 6x which does not have the plug in modules. No jumpers to worry about on this controller.

• Do the step LEDs light dimly when you try to move?
• Try changing the pulse_ms to 8 or 12.

[Kevycnc]

Hi, apologies for the confusion on the board type. The step LED's do show dim when trying to move. Other motor LED's go off until what I assume is the command completing, I tried to change the Pulse_us setting to 12 and then 8 ( I didn't see a pulse_ms in the file). At 8 it seemed the Step LED's were brighter when trying to move, but still no success. The appropriate step LED dimly lights, however it appears all motors lock whenever I send a jog command. Even though I only attempt to jog one axis at a time.

Appreciate the help on this.

[bdring]

If the correct step LEDs glow during the motion, the controller is setup right.

The signal that goes to the LED also goes to the driver.

Are you sure the driver switches are right?

[bdring]

All motors lock during any motion.

Many people will set idle_ms: 255 to keep motors locked at all times. This prevents drift between moves. You can always unlock with $MD or $MD=<axes>

[Kevycnc]

Hi, that makes sense on the motors locking up. I have went through the driver switches, rechecked motor and controller wiring and all seems good. Lights all proper when sending commands or trying to jog, except for the one that's not even in use. I am still concerned why there is the one random LED lit all the time on the motor 5 ENA led. Is this a problem?

Currently my motor drives are set to proper current for each motor. And they are set to microstep 4 which is 800 steps/rev. I changed my Yaml file in an attempt to get things moving. Im am a total noob at this Yaml so it could be something in my setup so far. I know on Tindie it was offered to have a file setup based on some information sent. I didn't do it at the time as I wasn't sure yet. I don't mid learning and trying, but wondering if I am fighting against it as well.

Thanks again.

[Kevycnc]

Success! I'm an idiot. It was a driver setting/switch. For future reference for anyone who missed it like me, they were set to 24V and I completely missed the switch to 5V. So now I believe I can adjust the yaml file to get it where I need.

I am still wondering about the random LED that's lit. Perhaps a bad LED?

Thanks for the assistance.

[bdring]

I think the LED might turn off if you use anything in the 16-31 range. Try adding this or change the number to the actual offending LED pin number.

user_outputs:
  digital0_pin: i2so.16

[bdring]

The LEDs actually helped a lot here, because we knew the problem was outside the controller.
