Hey Everyone,

I have been doing a bit of reading on Non Planar 3D Printing and thought it would be fun to give it a crack. Currently it is only a Linux based version of Slic3r that has the functionality so I followed some instructions of how to set up and build the Linux version in Windows 10 built in Linux Environment and quickly set up the slicer. I don’t have a profile for Slic3r as I usually use cura so there is a wee bit of tuning to do. I am very impressed with the outcome. Here is video

Even with the air pump part cooling I still had issues with it almost hitting the part so I turned it away.

I agree with @deckingman

Whilst all of the other counters would be nice to have, as a mvp, run hours and axis travel distance would be more than sufficient.

My understanding is it is not about the ac shorting to the dc circuit but more a potential difference building up between the dc rail and ground. Although you are measuring the output of the dc rail to its own 0v pin giving you 12 or 24v (what ever your power supply is rated to), due to the fact it is not grounded to earth, its has the ability to actually be a lot higher than that with respect to ground. It could be 30v or even higher. If for example the dc circuit is isolated from ground but then touches, that is when it becomes a problem. Sensitive electronics such as sensors etc do not like it.

That is my understanding of it. I am not a sparkie, but am in the pumping and irrigation industry where we have sensors (loop powered pressure and transducers etcm) on 24v power supplies that a) do silly things because of it or b) blow up in rare situations. By binding the 0v to ground it avoids these issues.

Correct me if I am wrong but I believe that is what our sparkie said the reasoning behind it.

Kind Regards,

Sam

@dc42 Jeepers, these sausage fingers will struggle with that. Might have to ask a mate. It is hard to see where the upper connection point is from that photo

I am currently upgrading my printer to run and print at much higher speeds. When I am needing to whip up a prototype, I don’t see why it needs to take 30 hours to do so have been spending a bit of time working on it. I am running the EXP1HCL boards on my x and y. I am running them at 48v and I have had the printer running at 1m/s and 30k acceleration. I have not yet printed at that speed as I have had to remake some parts, in particular the x axis gantry as the aluminium I used was too light and cause no end of grief with bed levelling. I am just waiting on LDO to bring out their high speed steppers with encoders so I can make use of the closed loop functions of the HCL board. I am pretty pleased with it. I also have the orbiter 2 and a magnum+ hotend.

I had the same issue with mine. The auto install through dwc failed and I had to update via bossa to get it working again

Cheers

@NitroFreak And from this thread

https://forum.duet3d.com/topic/11005/news-on-duet-3-release/2

David has said that the Duet 2 will still remain the mainstream board will minor development.

The magnetic filament sensor requires at least 2.03

Yeah I have no idea why that line was in there. I copied the restart on power fail from somewhere and it must have been in there. Oh well I am really happy you guys have sorted it for me. I was starting to get a bit deflated.

@dc42 is this something that you think you can connect into existing tool boards going forward, or will we need to buy a new tool board

@JoergS5 I am very interested in your progress so far. I am about to build a mini mill and will at some stage get a 4th and 5th axis so if you need help testing let me know. I will most definitely be 3-4 months off getting it done as funds don’t allow it at the moment so the project is being drip fed

@Exerqtor I have to agree. I have a few people who run klipper and the screen does make me a bit jealous.

@o_lampe https://youprintin3d.de use to do one. Maybe ask them and see if they can still do them as I can not find them on their website. They were a v6 heatsink that was watercooled

@dc42 ah bugger. It’s just where I currently have the two boards mounted is inside an electrical part off the side of the printer meaning they would need to be about 650-700mm long. I guess I could move the boards. Just a bit worried about heat as I will be heating the chamber at some stage

@dc42 ah bugger. That might be a pain. If I was to use shielded ribbon cable would that work? I see you can buy it, which I never knew about

@dc42 awesome thank you. Are they any better than the quadrature encoders I currently have. I believe they are 2000cpr

Simone has already done a write up on how to set them up.

There is a speed output pin which is pin PG.

Hey Everyone,

What’s the maximum recommended length for the ribbon cable?

Cheers
Sam

@oliof missed that. Thanks for pointing that out

What does Odrive use for their brushless motor control? I believe looking at the docs for them and Duet, they are going to be supporting Odrive
