@jonathanbrent if it's a Duet 3 board then you could also look at M917.

@dc42 Thank you, that makes sense!

@SpeedyDad
Maybe this helps:

; Drives ........

Makes sense. Thanks!

Replaced the stop switch and have not been able to reproduce the problem on demand as of yet.. Finished the current project without issues. Started the printer today and homed Y .. slowed half way to the switch but after that, could not reproduce it again. Will see what happens. I do not believe I have found root cause but will be a while until I use it again, so If you want to close this, that is fine, will just post any updates if the issue returns.
Thanks

@Miss-Rebekah If you are shutting off the VIN supply then the undervoltage warning is to be expected. I cant remember which firmware version that introduced the warnings.

@NIKwithoutaC said in Remote Mount Thermocouple Daughterboard?:

I have asked them in the past if they offer parts to convert the printer to allow the Duet to control the bed and I was told that they do not.

I know that they use an external controller for the larger printers, is that also the case here?

This worked! It was the homing issue G92. Thank you!

@Lachlan the backlight inverter can be replaced though it is a tricky soldering job; see https://docs.duet3d.com/en/User_manual/Troubleshooting/Parts#paneldue-tft-panel-backlight-inverter-ic

@droftarts thanks for the help.

@trulm said in Scanning Z Probe giving erratic Z values:

but when I start the G29 or G32, all points of the mesh are on 0.0mm deviation.

Can you explain more what you mean by this?

@semi55 said in Duet 6XD power peripherals through 5_EXT_IN:

Can I connect an external 5V power supply to the 5V_EXT_IN pin (with no jumpers on the 5V section) to give enough current to power the LEDs and the servos

Or should I power these devices directly from the external 5V power supply?

Yes, you can do either of these. Use the +5V pin on the 5V_EXT_IN connector. See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview#h-5v

or is this pin only for controlling an external power supply with an SSR?

No, that's the 'pson' pin, though it is on the same header.

Ian

@guitartoys Thanks for posting. What Duet are you connecting it to? Can you take a picture of both ends of your cable in situ, and post it?

Ian

@3DPotter as Jay says, you would need to compile your own firmware to do that. The pins used are defined in file src/Config/Pins_DuetNG.h. A further possible complication is that the current code assumes that all step pins are on Port D, so if you swap a step pin with another pin that is not on Port D then a code change would be needed too.

@stellator Normally, the 'X' stepper is back right on a CoreXY, and the 'Y' stepper is back left. I think you have these the wrong way around.

I think it should be:
Motor XY - 'Y' motor - 1 goes to Duet2Wifi E0-Stepper (driver 3)
Motor XY - 'Y' motor - 2 goes to Duet2Wifi Y-Stepper (driver 1)
Motor XY 3 - 'X' motor - goes to Duet2Wifi E1-Stepper (driver 4)
Motor XY 4 - 'X' motor - goes to Duet2Wifi X-Stepper (driver 0)

So your M584 should be

M584 X0.0:0.4 Y0.1:0.3 Z0.5:0.6:0.7 ; set axis mapping

Then check the direction of movement for the motors, using https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_coreXY#testing-motor-movement, reversing the pairs of motors' direction as necessary.

Edit: I don't think it's 4WD problem, so long as the pairs of motors are working in the same direction as each other. Though it may be easier to get it working in 2WD first!

Ian

@dc42 very true, very true.

@Caveman-0 So would you able to find out is it the power supply or the board? Since I am having issues with Over-voltage and causing board to shut down. And hence wondering if it is the board that I need to replace or the power supply.

@CNCsimon

Thank you for your help

Was a pleasure … 🤓

@Amagatth Please create a new thread and include as much detailed information as possible. You can reference this thread if you think it's relevant.

@janjoh I use a simple macro to turn on and off the leds...

Definition in config.g

; LEDS M950 P1 C"e1heat" Q500 ;use heater 1 outupt for LED M42 P1 S1

macro LED ON/OFF

if state.gpOut[1].pwm == 1 M42 P1 S0 else M42 P1 S1
