@bearer its all inside a case dangit... lol

Good morning... So yesterday as I was toying with ending gcode etc I think i wanted to try out the sleep command.
Woke up this morning after a print had finished and cant connect to my duet. Powered it off, back on again, nothing.
Is this normal behavior? Just curious as to why suddenly ive lost wifi access to it.
3.1 fw version , duet wifi board.
thanks

well, the default is turds that seemed to have resolved it. keep u posted.

not sure how 4000 got put in there.. but that would explain why this thing when asked to move up 5mm goes up lets see about 10x that haha

whats odd though is the nozzle is perfect when z is at 0. its only after the print starts does it raise up. Its like the gcode from the slicer is telling it to move up.
But here is the first bit of gcode.

I know its exactly -3 to where I need to print.
So can i just modify that G92 Z0 to be G92 Z-3?

thank you kindly for the help

@Phaedrux i was missing the M501 printing happily away now..
The only outstanding issue now is the fact that my printer automatically goes up 3mm (default) before it starts printing. So its air printing.

i can mod the Z offset in slicer settings, but id rather add it to firmware.
Should be fairly easy, but I am not smart in these ways haha
thanks for the 501 help

Ok, i went ahead and rebuilt it.
Everything wrks except the bed heater.
its a slow bed heater, so its throwing a fault.
Ive tuned it, and made this change.
Still happening though... any ideas?
thanks

Yeah, i was afraid of that... I just have a problem knowing all the right stuff for the configurator...
The config I have there is mostly a copy/paste (to some extent) of my version 2 config.. so yeah clearly something is amiss.

So, I have a quick (hopefully) question.

I just replaced a thought to be bad duet board with a new one. Finally got the FW upgraded and am on 3.x.

I moved over some of the stuff from my old config.g and the axis are working great.
Everything is homing, times are good.

However, when i try to heat up the bed, or the hotend, I have the bed at
-273.1 and the heater 1 basically MIA.

I am 99.9% sure I wired everything exactly the same as before. I am happy to provide any details to assist you in assisting me.
thank you all...
Here is a copy of my config.g

thank you

So I am running a duet wifi (and I love it) but I have considered adding ABL to my setup. Just curious is bl touch seems to be the best option?
I have a modded CR 10 which includes a Nova hot end with a duet board. Otherwise its fairly stock (i guess a new extruder too).
Just curious which kit to buy, or what I need to buy. It seems there are TONS of links on amazon to large kits, small kits, etc... Ive never bought a bl touch, so Im not sure how much of said kit I would need???
Thank you guys/gals.

so yeah, i think that fixed the issue... Ive been printing most of the day now without issue... Im doing retraction testing now...

I think i have it resolved... THINK.
I have a line of code M106 P1 B0 X0.6 S0.3 I0 F100 H1 T120 C"Hotend" ; Set fan 1 (extruder fan) value, PWM signal inversion and frequency. Thermostatic control is turned ON

basically that turns on the fan when the hotend gets to 120C.
However that S.03 only runs it at a slow speed. Changing the S.03 to S1 made a HUGE difference.
Before I shot with a laser thermometer the heat sink at nearly 60 degrees C.
After the change to the fan speed, 27 C.

Was just some confusion with my friend (inventor of nova) on different models of fan I got vs some others. Simple mixup. Ill report back on whether this is the fix for sure. but 1 hour in to a PLA print it appears to be the case.

Retraction didnt seem to make a difference... 0 retraction or 5mm. no difference.

This is a picture of the issue in a nut shell. so I can manually push filament through, but as soon as I stop. then start a real print, its like the extruder itself cant push the filament through. Could I need a new gear? How likely is that?
You can see a bulge right there too, i THINK that is a ring inside the bowden fitting on the top of my hot end. if so, the heat is WAY higher than it should be.

THoughts?

So its happened with multiple PLA filaments
2 different PETG filaments as well.
It has not yet happened on ABS, but i think thats more likely because I havent tried printing anything large with it yet. ABS prints have all been small.
It MAY be heat creep. I will try a larger ABS print now to see what happens.

I dont have any pics of failed prints, but i know all the answers.
Part fan is a BAF https://store.3dpassion.com/collections/store/products/baf
The fan blows directly on the part and I suppose the hot end as well... However the hotend maintains its temps just fine... Its a great hotend in that regard. I have even ramped PLA up to 220c to see if it was potentially cooling pre maturely, but no... it still occured.

WHen it skips (the first few times) it was about layer 20 of a large print, and it basically just skipped back, and missed a tiny stretch of extrusion. Yes, inconsistent extrusion. Eventually after a little while of this behavior it just clogs or stops extruding...

Hobbed gear slipped on the filament. Not making any odd noises except for when it skips.

I am friends with the creator of Nova. we are working on it. Trying some diff things... kinda stuck at the moment.

Too much retraction would be how much? I had it set at .6mm, and 2mm (because it oozed a bit much with .6). Doesnt seem to be too much retraction... too low retraction causes major oozing... I guess I could try VERY low retraction .5 for example and lower the temp a bunch on the Hot End to control the oozing.

Part fan has no impact. Its happened in layers 1, 2, 3 before cooling fan, or at layer 20 when the fan is on.

Never heard of the cup of water test.

Layer height .2 .5 mm nozzle, speeds vary from 20 - 100mm/s mostly 40-60 during this time where its happening. Speed up , slow down doesnt seem to impact things. Gear is not loose (ill double check tho).

I am more than willing to swap the CR10 extruder, IF i know its the cause.

I thought it might be a gap between my hot end and the PTFE fitting not being tight, but I remedied that and it still skips... Im really confused as to why this would be happening...
Any help would be appreciated.
thank you

So My extruder (stock cr10) has been skipping at layer 19 roughly of a duet wifi CR10 case i am trying to print. Up until then, not a single skip.
Ok, I thought maybe a model issue or something...

New model, sliced it up, and it started skipping in layer 1 this time. I am so freaking frustrated... Happens on PETG, or PLA, so I assume anything.

I am running a Nova Hot end, hence the fast speeds on X Y. The hotend is extremely capable of 200mm/s easy.
Regardless of that, when these issues are occuring I am printing less than 100mm/s or even slower..

the Y was just moving opposite when I homed it... so i reversed it..
we shall see prints are looking good though.

And yes, the bed is all the way back against endstop, and X is left, so 0 0 is front left
