If you want to ship it to me, I'll take a shot at repairing those traces.

I have a tiny soldering tip and a stereo microscope and some REALLY small gauge wire.

I live in Massachusetts, but I doubt postage is going to be very expensive for this small and light part.

Let me know if you want to try this and I'll PM you my address.

Just to be clear: if you connect the laser PWM input to the Laser/VFD output on the Duet, and configure a fan using M106 F0 C"out9", then you can control the laser using M106 P0 Sxx commands. Correct?

If that is the case, then you should be able to use M452 C"out9" (provided the out9 pin is free when you do that), and then control the laser using the S parameter on G1 move commands. Note, the laser will only be on during G1 movement commands, for safety.

Since it is a release candidate, you would need to add the unstable repository to your pi using these steps

If you're not comfortable with that, you can wait until 3.01 is finalized which shouldn't be too long now.

Most spindle controller accept 0-10V inputs, so to drive them you need a 5V PWM to 0-10V converter. They are available on eBay and Amazon. Duet 3 v1.0 provides an output labelled LASER/VFD (which shares a control pin with OUT9) with a 5V signal level for this purpose.

Duet 3 doesn't have wifi, and to get access point functionality with the rPi you need to configure the rPi with hostapd.
