I bought the assembled version of the Prusa core one+ (gen 2). Got through the setup and calibration until hitting a (literal) snag when attempting to calibrate the filament sensors.
The assembled printer is supposed to come with a bit of orange PLA filament already loaded, sticking out of the end near the spool holder. I can see the orange filament in the PTFE tube, but the bit that’s supposed to stick out seems to have snapped off. Telling the printer to unload the filament doesn’t do anything.
I’m coming from a BambuLab A1 Mini, so I’m very much in the printing side of the hobby and not the printer side of the hobby, and I get a bit lost when the first step seems to be to completely disassemble the business end of the printer.
You can look through the assembly manual for the kit version, and find that the black 3d printed elbow that attaches the Bowden tube to the top of the hot end just slides right on. So you might need to undo a tie or two but it should be easy to pop that off and get the filament out.
Update 2: I was able to get the PTFE tube out of the side sensor but I tore the collet out as well and it went flying. Against all odds I was able to find it, but now I have to see if I can reinsert it.
update: It looks like I need to detach the tube from the front sensor and I can’t do that without removing the side panel which is riveted to the frame.
I’m not sure exactly what you’re saying but you certainly don’t need to drill out rivets to get to it.
I assume you’re talking about the sensor at the start of the tube. Assembly of that one is step 7.19 through 7.21, and attaching the body panel on that side is step 7.40 (maybe look back as early as 7.35 for the prep work).
You might also try talking to Prusa support.
Thanks. Will take a look after I’ve had a full night’s sleep.
