@droftarts Yes!

That did work to get the probe to function!
I just need to setup the z probe routine for bed leveling.

I am running into a different error, trying to have multiple z axis motors.
Only one of them is functioning. Driver 2 with a jumper on the ZB segment.
Then trying to pair the driver 6 and 7 to the Z axis.

Is this correct? When I jog after M564 H0, I only have one drive moving.

@droftarts !

Attached a picture of the wiring of the board, when all plugged in and the BLTouch.

White = Z Probe in
Black = GND
Green = yellow = E2_PWM
RED = 5V AUX
Blue = GND

@droftarts Thank you.

When I plug in the Probe to PWM1 I get an over voltage error. The screen goes white. I unplug it, of course I don't want things to fry.

@infiniteloop
I was referring to this page on the documentation.

Hello,

I am setting up a duet 2 and BL Touch. But having some trouble. I tried looking at previous forum posts, but I am not getting the same results or understanding.

I have this in the config file.

; Endstops
M574 X1 P"xstop" S1 ; configure X axis endstop
M574 Y1 P"ystop" S1 ; configure Y axis endstop
M574 Z1 S2 ; configure Z axis endstop

; Probes

M950 S0 C"duex.pwm1" ; Duet 2 WiFi/Ethernet + DueX2/5
M558 P9 C"^zprobe.in" H5 F120 T6000 ; configure BLTouch probe via slot #0

But I don't understand when it says "First, you need to allocate an unused heater expansion channel to reconfigure as the servo control for the BLTouch."
Am I using H5 in my case?

When I plug in black and white into the Z Probe GND and Z_PROBE_IN. Then the other wires into PWM1 it gives me a voltage overload warning.

Any help appreciated! Thanks

@dc42 Thank you for the info!

I will try that first.

Thank you

Hello, I have a custom built machine for work that is running off a duet 2 ethernet and duex expansion. Nema 23 motors. I can send the config file if needed.

I am getting a random error code 1 in the middle of prints.

I am using cura as a slicer. Please let me know what this error code is? Advice?

Thank you

@droftarts

I even tried to shut off the Bed as an active heater so it wouldn't try to use any voltage in sensing the bed. It cancels everytime even at 240 deg C.

@mrehorstdmd I am using a DC psu for the motherboards.
And I am using the attached terminals for the 24V output to the bed heater.

@droftarts Yes. I am using a 50W 24V heater. The PT100 sensors work well and I have the config setup to have a pt100 as the active sensor for each of the extruders.

@jay_s_uk The bed i'm only trying to max at 100 C.
But that still has trouble reaching 90 +.

The hotends are setup as.. nema17 motor, bondtech bmg direct drive extruder with a mosquito magnum hotend with the high temp heater and pt100 temp sensor.

Hello.

I am setting up a duet 2 ethernet and duet 5 board for a 3D printer build. It has Nema 23 stepper motors driving ball screws on the x (600mm), y and y' (300mm0, and two z (500mm) axis. Dual extruder with BL touch, BMG direct drives to mosquito high temp hotends.

I did my best to spec out what is needed based on the motherboard outputs. But I am having the following issues.

The power supply used is a 24V 50A psu, but the temperature tuning is not able to achieve the temperature that is required. 250 deg C. So the autotuning keeps canceling itself. For both hotends and for the bed heater. The bed heater is 24V 400W.

Why is this happening? I have tried making M307 have a long dead time so it can reach temp, but still is not working.

Any help is appreciated!

Hello,

I am building a custom 3D printer for work.

It has a duet 2 ethernet and duex 5 expansion. Moving nema 23 stepper motors on a gantry in Y Y' X and two Z motors moving the bed.

The issue I am having is that it seems that the duet 2 cannot handle the heated bed that i have selected based on the documentation. The bed is a Keenovo 300mm x 600mm at 24V 400W of power draw. It cannot heat up fast enough to reach temperature and faults out even during a tuning phase. There is also a voltage drop when the bed heater is active.

Did I select the wrong spec bed? I believe I need to now try to use an extra power supply and SSR to manage the bed. Can I monitor and control the bed heat using DWC?

Does anyone have any pictures or setup information. Other than the docs page?
https://docs.duet3d.com/User_manual/Connecting_hardware/Heaters_bed

Any help would be great! Thanks

@T3P3Tony
I think I figured it out!

I was changing the M307 setup in the config.g file.

But I forgot that the config override contained heater settings aswell. So those would eliminate the correct tuning of the config file.

I have updated the config override and it is remaining stable at printing temp.

Thanks, still learning, again

Hello,

I had this issue before, I thought it was solved, but it is still ongoing.

I have a small printer. With heated bed (24V), Bondtech drive and Mosquito magnum extruder, 24V heatsink fan. (24 V heater with pt100 temp sensor and pt100 daughterboard).

I have tuned both heaters. The bed heater will stay consistent at temperature that was set.
However the extruder will go beyond the set temperature by almost 10 deg F.

What could be the cause of this?

config.g

Thank you

@T3P3Tony I have them uploaded. But I know they are not functioning properly for the endstop I want to use.

How would you write a probe macro for this situation?

Sorry, I don't have that much experience working with the reprap language for duet.

@T3P3Tony
I have a Z endstop at the top of my gantry head and a stationary endstop on the spoilboard 20+mm higher. I want the tool to touch that endstop and set the new Z height. Based on whatever tool I have setup.

Even with the M558 P5 C"io5.in" H180 F700 T1000 only, I am not getting any response from the endstop to trigger the Z movement to stop.

Hello,

Posted on CNC page but I haven't gotten any reply.
https://forum.duet3d.com/topic/31780/z-probe-setup-for-cnc

Anyone know how to do this?

I want to setup a stationary endstop switch as a z probe for tool height setting. On duet 3 6xd

Anything helps. Thanks

Thank you for the advice!

I feel dumb, but I forgot to switch my new power supply to 110V for US.

So it would drop voltage when operating, expecting 220 input.

Retuning heaters now.

Should be a resolved issue! Thanks again!
