@bearer thanks for the knowledgeable response and helpful link. Very good to be aware of going forward.

Also, the Duet3 has its jumper on internal 5V enable so the SBC is powering itself and the Duet is getting power from VIN

@dc42, that would be great but if it isn't quick don't worry about it. We have other workarounds to the issue and while what you proposed is the most elegant solution, it isn't necessary yet. In the future it may become more important though.
@chrishamm thanks for the suggestion, I will keep that in mind as we are currently using the DSF for some other functions.

@bearer Unfortunately, I can't although this would be a good work-around that requires little firmware alteration.

Hello all, I have a quick question. I was trying to debug my Duet3 earlier as I wasn't getting a response from the board. The issue is fixed now but I ended up plugging in the USB on my Duet3 to my computer to get a COM connection while VIN was connected to 24V power. I was wondering after the fact, was this safe for the board, or did I potentially fry something? I was looking at the getting started page for the Duet3 and it has a small section about this but the wording was a little vague.

Thanks for your time.

@jay_s_uk oh that is really interesting! Thanks for the idea.

@bearer the pump is a ViscoTec extruder, it is a screw type pump. Thanks for the thoughts!

Thanks both for your suggestions! I am slowly making progress. That repo is actually what I am using to develop a solution and am getting close. I am a little confused as to some of the matrix operations but I should be able to replicate it nonetheless.

@seraser glad you finally compiled it! Sorry I didn’t respond in time.

Hello everyone, my company is working with printing thermoset resins out of a mixing extruder. Since the resin is time-reactive, once X amount of time passes, the static mixing tip clogs.

I was wondering if there is a way to implement a process control so the printer knows to purge the mixing tip every X seconds since the last extrusion. This way G-code doesn't need to be post-processed to add purges from simulating the g-code.

Now that I am thinking about it, the DSF would potentially let me stream G-Code to the printer and the python program streaming the G-Code could take care of this?

Thanks for your responses,

Best,
Garth
