Voron 0 + Duet 3 Mini

PaulHew

@fma I am building another V0 but the V0.1
I have been toying with the SKR, cheaper if you get it shipped from China, but I think after seeing this post has made up my mind, Duet Mini !
Just need to look at the backpack for the SKR and LRS-100 and move the heatsets so the Duet mini can be mounted on the Underneath.

I am also thinking about WiFi Version, but would have to hook in with a USB to set the WiFi connection up each time, wherever I might take it.
Decisions decisions!

Already have a 220V heater so will keep that as part of the build.

@paulhew Forgot to say that I will use a 24V heat bed. I don' like having LV here, as this printer will be used by children...

The cult of Voron seems to catch significant momentum recently, with vendors offerings kits and products that target vorons (LDO frames, Fsyetc Spider, Funssor metal parts, etc).

I am working on my V2.4 sourcing, most parts already arrived, black Misumi extrusions will take a little bit longer to arrive.

So far Klipper seems to be recommended and most common firmware and Spyder seems to be the upcoming recommended controller.

Next they will expand, I think, to desktop CNC machines but yet to be seen.

Do you have room for the larger power supply? I heard that the V0 design is very tight.

As I drop the Bowden extruder and the Rpi, yes, no problem. The Duet3 Mini fits behind the Z axis, and the power supply fits below.
And a 120x120mm heatbed does not need a lot of current...

@fma Is there an available mount for the Mini that fits on the 15x15
I looked in voron users but I cannot find one.

@paulhew I don't own a Duet 3 Mini yet, so didn't look for a mount. But I was thinking to make holes in the rear panel, and mount the Duet with spacers...

It has the same hole spacing as the Maestro, so if there is a mount for that it should work.

PaulHew

@phaedrux Friend just designed one for me.

He is good with F360
Just need to buy the board.

PaulHew

@phaedrux Sorry, my manners. That is good info, thank you. I will look for it so I can share.

That's a skill that worth the learning time IMO.

DanJunior

I'm just wondering,if someone has a config.g to get the required esteps as reference. I'm just configuring my V0.1.

Phaedrux

@danjunior Which extruder exactly?

PaulHew

@phaedrux The V0.1 is a DirectDrive unit, BMG internals and the LDO Pancake stepper.

Mine V0.1 is offline at the moment as I am going to have to rebuild the DD unit

even at 350ma it cooked again.
The rating is suitable for High Temp applications..... So I and possibly like others think that it is suitable for an enclosure, which it is
What I did not realise that the motor will heat itself up also, more than any of the OMC's I have been running with no problems @80% of their rating.

Slightly disappointed that this info is not displayed clearly when looking at general info on the motor......

oliof

@paulhew depending on your microsteps, it'll be 345 or 690 steps/mm on the LDO pancake stepper meant for the Orbiter.

This is what I have on my V0.1 + Duet 3 Mini 5+, with OMC steppers. No guarantees it's correct, still tuning in and adjusting, but it's printing things reasonably so should be a good starting point at least. Also, critique welcome

@keyz182 What OMC have you got on the Extruder?

I am interested
I pray you do not suffer my fate where the LDO motor destroyed my DD plastics.
I was running 800ma, later to find that was too high and should be about 350ish

That's the one. Yeah, it's a bit high, as I said, still tuning. Put probably a roll of filament through at that amperage though and so far it looks fine (had the extruder disassembled yesterday).

PaulHew

@keyz182 Thanks for the info.
Going to steal some of your config!

My LDO even @450ma was hot enough to burn my fingers.

Might get one of those steppers, not trusting the LDO at the moment....

Thanks again
