Similar issue to the fan problem...
If I try to print with the only the 2nd tool, it will heat up and extrudes plastic, but the 1st tool will make the movements.... Thanks for the help!

I just noticed, that both tools have X and U listed... Shouldn't the tools only have the Axis they will be on? But that is the Axis offset...

I can move all the tools manually from DWC or the PanelDue. My homeall.g also works for all axis.

Phaedrux

Do you get any errors sending M98 P"config.g" ?

Phaedrux

See here for tool configuration. I think your first tool should only have X and not U.

Yes.

That would indicate you've got an G1 S1 in your homing files where it should be G1 H1.

If I would like to have independent Z motors on a IDEX Cortesian printer for auto bed tramming, would DUET 3 EXPANSION BOARD 3HC, be the correct expansion board to get, or is there another, possibly better option? Is there anything else I would need to make it work?

That's one possibility. You should connect the 3 Z motors to the main board. Probably best to also connect X, Y and U moors to the main board, and the E motors to the expansion board.

Another possibility is to use two tool boards, This may be the best solution if your extruders are direct drive and you can accommodate the tool boards in the print carriages.

BlueDust

@dc42
This is the printer/kit I built.
https://www.ratrig.com/3d-printing-cnc/3d-printer-kits/all-3d-printer-kits/rat-rig-v-cast.html

I only really need one tool board for one extruder, but not sure how I would mount it to the carriage. If I did that, I could see getting two, one for each hotend.... If I did that, wouldn't I need the DUET 3 TOOL DISTRIBUTION BOARD, and then 2x DUET 3 TOOLBOARD 1LC?

BlueDust

@Phaedrux
I rearranged the tool gcode to make it easier to understand in config.g, and that error is gone.
I didn't see a G1 and an S1.... So not sure what it was complaining about.

The tool distribution board isn't essential, but it makes the CAN and power wiring to the tool boards easier.

BlueDust

@dc42
Are you saying I could wire in two, DUET 3 TOOLBOARD 1LCs directly into the Duet3 (without a Distribution Board)?
When reviewing the instructions, it looked like I could only wire one directly to the Duet 3 at a time.

Probably one of the homing files.

BlueDust

@Phaedrux
I attached my configs. I may have fixed it and not noticed it before you you replied to look into the homing files...

Still not sure why I can't print with the 2nd tool. (extruder will extrude, but temp may not turn on, and it will not move. As I started with the default code from the Configurator, and it doesn't look exactly the same as the code shown in the Wiki, I am not sure if I screwed something up, or just not sure/able to find what the problem is.

deployprobe.g config-override.g bed.g tpre1.g tpre0.g tpost1.g tpost0.g tfree1.g tfree0.g stop.g sleep.g retractprobe.g resurrect-prologue.g resume.g pause.g
homey.g homex.g homeu.g homeall.g config.g homez.g

Thanks!

Phaedrux

What slicer are you using?
How are your tools configured there?
Can you post a sample of the gcode being used?
Are you able to manually change tools successfully?

BlueDust

@Phaedrux
I have tried ideaMaker and S3d, but still new to this and have been concentrating on the Duet3 config.
I have tried a few times and cannot for sure say what file did what when I tried to print (or whether it was S3d or iM). The best attempt I had, tool0 was printing fine, and tool1 was extruding plastic, like it thought it was printing but was not moving and still in it's home position off the bed.
I will try to print a dual/copy print again, and share the gcode.
While printing, I have been able to change tools and get tool1 to start printing in place of tool0, but as it wasn't up to temp yet, I watched it pretend to extrude for a minute and canceled the print. When I pick tool1, tool0 will go into stand by, always seems finicky as temps were not set before hand (as the tool was disabled). I haven't tried to make tool1 active before a print to see if it can follow their and complete it successfully. Once I am done with this print/test (trying to fix some quality issues), I will try it.

Thanks!

@Phaedrux

I am still in the middle of printing parts (family project) but plan to get back to testing IDEX tonight.

@dc42
To keep wiring simple, I am now thinking about buying DUET 3 TOOL DISTRIBUTION BOARD and 2x DUET 3 TOOLBOARD 1LC. Is the CAN bus cable a standard RJ-11 telephone wire? Anything I should be concerned about if I make my own cable? Pins/wire order? (same order on both sides - straight through, or crossover, still looking in Wiki... )? Not sure if the boards come with cables...

Thanks!

Phaedrux

I think the G1 S error was from pause.g

;Duet IDEX example Code
M83 ; relative extrusion
G1 E-2 F3600 ; retract 2mm
G91 ; relative movement
G1 Z2 F500 ; raise head 2mm
G90 ; absolute movement
G1 S2 X-52 U352 F6000 ; park both heads

That last line should have H2

Same thing in your tool change files. They are using S2 instead of H2.

Phaedrux

Just to verify, are your tools motor and heaters defined correctly?

M563 P0 S"LeftExtruder" D0 H1 F0:1
G10 P0 X0 Y0 Z0                                    ; set tool 0 axis offsets
G10 P0 R0 S0                                       ; set initial tool 0 active and standby temperatures to 0C

M563 P1 X3 S"RightExtruder" D1 H0 F2:3 
G10 P1 U0 Y0 Z0
G10 P1 R0 S0

Drive 0 and heater 1 are paired and drive 1 and heater 0 are paired.

Otherwise I can't see anything glaring with your config files, though I'm not an IDEX user, so I'm not the best judge.

BlueDust

@Phaedrux

Thanks!
That code was copied directly from the Duet Wiki. I will fix it.
Thank you!

BlueDust

@Phaedrux

Yes. It is correct. When I manually move tool1 (right carriage), it moves. Also if I manually tell it to heat up, turn on part fans, (hotend fan turns on at 40c), and extrudes plastic, it does.

One thing I do not understand, is that if I have to setup a 3rd tool to have IDEX work and print in mirror, or copy (maybe a 4th tool?) modes? Or do I just set that up in the Slicer?
I had assumed, that was optiontional, where I could setup the Duet3 to always print in copy/mirror, or setup the slicer/Gcode for the model I am printing to do it as needed. And when I say to do this in the slicer, I don't mean add code in the beginning of the file. I mean to just tell the slicer to print mirror or copy, and then enable the 2nd tool (with settings for it's temp and when the cooling fan kicks in).
I am starting to assume my assumption was wrong.
Thanks!
