Just wondering , i was told this is correct by the tech departments, and i disagree. Was hoping someone here can share a video showing the same thing or what it suppose to be doing.
the above is the extruder motor first extrude then retract , for what ever reason mine extrudes when i tell it to retract. (it use to push the filament out from extruder.
the above is just showing what the motor does when connected to the extruder , watch how it extrudes even when “retracting”
Is this normal??? cause the tech people say so. (never did this when it was new is 2 months old)
I don’t believe that’s normal, retract is just that. FWIW, my K1C does extrude a bit when you press extract, then it backs up and indeed extracts. I don’t get any clicking, that screams out to me that something’s wrong!
The only time I’ve gotten that kind of behavior is when I had a filament jam. However, it still tried to extrude, just couldn’t move the filament, so it was clicking.
Yeah, its weird i retract and and it dumps alot out and goes not as you see above. But before it did exactly what you described. Still fighting with their tech support, printer dont print much presently. as not retracting causes a lot of issues.
BUT thank you for letting me know i am not going nuts and something is wrong, after tech telling me its working as intended for the past 2 weeks now. Hope for a fix , exchange, or refund. so much for their flagship machine.
I was able to see your video finally and yes it is not retracting as it should. I did notice that after you pressed retract it did started extracting right away when it should wait for the nozzle temp to build up to 230C.
Have you done any mods or changed anything that might affect it…?
Try a factory reset…and then reload the latest firmware. See if that helps…
It will start right away if you set the nozzle temperature first. When I’m changing filament, I set the nozzle temperature and then do my retract and extract until I get a good flow. It speeds the process since the nozzle doesn’t start cooling while I’m loading new filament. Also, I like to have it sit with the nozzle at temperature for a couple minutes before I start trying to extract. I hurried the process once ended up with a filament jam that I had to clear.
Heh, well it started right away as it was already hot from previous tests we did before i filmed it.
no mods, its only 2 months old and i only got to use it for maybe 5 weeks before this issue started. With the tech support (i still think its just ai constantly saying did i check if its clogged) i have factory reset, rolled back the version. Have taken it apart to check for clog, tried different filaments, I have a buddy who been doing 3d printers for years, (i have about 3 years of experience) and we both think its something with the motor control board. But “tech support” still asks is it clogged? we sent machine logs recently, only to have them say we have to do it again for reasons. We have asked for some 3rd party affiliate for repair, or replacement machine, but am getting closer to demanding refund.
Yep, that’s usually when I’m changing filament, to change colors. When I printed my little Jeeps, I had five total colors to print. Black, brown, white, and two shades of green. I’d print a plate or two of one color, then swap filament for the next color.
Its meant to extrude before it retracts, the reason it does it this way is to allow for the new printers and the upgrades coming for the k1 series printers, that will have a cutter in the hot end. So the cutter will cut the filament and then extrude what is left in the nozzle, thats what is coming out. However it not meant to make the clicking sounds, so there might be a problem there.
