@keyz182 Thank you

@keyz182 Thank you. I am clearly very much a newbie in this! I think I understand it now. Assuming I am reading everything and looking at the diagram correctly...

1. the H1 Duet Header on the board plugs in to the matching pins on the expansion port on the duet3d.
2. The board does not require a V_IN as there is 5V from Pin 1 on the H1 header.
3. PWM from CN1 goes to the laser driver (thinking of a NEJE https://neje.shop/collections/laser-module/products/neje-a40630-laser-engraver-cutter-module-kits-fac-7-5w-output) and there will be nothing on Pin 1 V_IN in CN1
4. The NEJE laser would be powered by the 12V power supply that comes with the laser.

It will probably be a few weeks before the NEJE arrives. So, fingers crossed!

@smoothquark Sorry for resurrecting this old thread. I bought a board from @keyz182 (thank you very much) but never got around to using it. I had been too busy with other things and left aside my Ox CNC and any thoughts of a laser attachment until recently. Getting back to it now, but I cannot remember how to connect the board. Do I just plug in the header to the expansion pins and ignore CN2 or do I have to use a separate 5V for the V_IN/GND on CN2? Also, my duet runs on 24V V_IN with 2 24V fans always on. So, I suppose the PWN Fans and Heater3 would be on 24V? Will this be a problem?
Thank you and apologies once again.

Thank you. My parts should be arriving today and assuming all is well, I shall be ordering the duet3D soon...

Hi! Please pardon my newbieness (if there is such a word). I have been trawling through the wiki and forum but have not quite found the info a need. Apologies if I have missed it somewhere...

I have ordered some parts to build a ooznest ox but without the controller as yet, as I am planning to get a Duet3D. It has 4x Nema 2.8 motors for a dual-Y axis CNC build. My main use will be light CNC and laser (probably max 5W laser diode) and hope to add some 3D printing at a later date, bearing in mind that the current gantry does not allow much travel in the z-axis. It may be that I might build a separate 3D printer, but would like to use the same controller and swap cables etc. I am planning on using Fusion360 for the CNC and 3D and inkscape for the laser generating gCode.

I am getting confused with the wiring for the laser and CNC and unfortunately, the wiki is not idiot-proof enough for me. As far as the steppers are concerned, my understanding is that X goes to X, Y left to Y, Y right to E0 and Z to Z1, Which leaves E1 free later on for the 3D printer functionality. I am planning to get a 24V 350W PSU initially.

Questions:

1. I guess it is not possible to have both Y's wired either serial or parallel?
2. The wiki on the laser talks about a H1 header? Where is the H1 header? Am I missing something obvious?
3. How do I control the laser (No. 2) and CNC. I thought I could use E1 as implied by the gcode docs, but is this not the case?
4. I was thinking of getting a 48V 400W air-cooled spindle for the CNC function - can I still have this running off the high current heated bed output, wired up to a 48V PSU (bearing in mind correct wiring). I am assuming 24V 350W would be sufficient to run a 5 - 8 W diode laser?
5. If I were to use a 48V PSU for the spindle as above, can I use that to run two 24V heating pads wired in series, as I do not think the 24V 350W PSU will be sufficient to run a 40x30 heating pad (~500W at 0.4W/cm3)

What I would really like is keep the stepper connectors fixed, and swap out cables easily depending on whether I am using the laser, CNC or 3D printer and switch on the extra power supply accordingly.

Once again, apologies if this is all covered somewhere...

@keyz182 said in Duet3D wifi for 3D printing and laser cutting/engraving:

Also, if anyone in the UK wants one of those boards mentioned on the wiki, I've got 9 of them spare - JLBPCB had 10 for $2 if ordering through EasyEDA, so I ordered extra components too.
I can send them assembled or unassembled (none are assembled currently).

Hi! I have just registered on this forum, and yes, I would like an assembled board please.
