Voron 0 + Duet 3 Mini
-
I'm just wondering,if someone has a config.g to get the required esteps as reference. I'm just configuring my V0.1.
-
@danjunior Which extruder exactly?
-
@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......
-
@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).

@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

I have a box full of V2.4 parts waiting for the Misumi extrusions to be built.

Hi, i´ve already my V0.1 running. It was the mini afterburner. I´ve just calibrated the extruder...started with 400 ... ended up with 780.
Till now there was nothing melted. I´m using the LDO 36STH20-1004. Running with 900mA
What i had now is that my Duet Board doesn´t like to stay without cooling behind the panels. That socks really.
I´ve to design now a cooling fan for it. Really bad on this little thing with no space.
