I've been working with a modix big 60 and my company wanted to double the output in the same floor space for medium and small parts. It's a little bit of a Frankenstein's monster, but its working great!
I got a duplicate gantry and made some aluminum parts to lock the gantries to the same axis. The first test were some classic benchys. They actually came out at a great quality, even the slave gantry!

Here is the config file adjustment! I created a third tool that runs both of the extruders and heats them up to the same temperatures.

Lastly, I had to create a cura profile that would work. Basically, I created a third tool in cura and cut the y-axis in half for the offset of the second tool head.

The machine thinks it is only creating one object, but actually outputting two!

Let me know what you think!

@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

@dc42
I was able to get a port that connected and YAT got past the error.
I have connected, changed the gateway and subnet.
I was able to access the duet panel controls.
So this aspect of my projects I can say is solved!

Thank you very much!

@t3p3tony
Yes!
I can still select to print a single item with the primary or secondary extruder.
And its a much less expensive adaptation than buying an entire printer for idex, and not having all of the bugs that a "new" idex type of system has currently.

Thank you @Phaedrux

It was my duet 3 and duet 2 's default gateway that was not set to the network gateway!

Not sure if the windows command should be included in the getting connected section.

But I did need to use Command Prompt -> ipconfig/all command to identify the correct network subnet and default gateway.

Thanks again

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!

@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

G31 P500 X0 Y0 Z0.7 ; set Z probe trigger value, offset and trigger height
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.
