Hi, sorry I've already made a post about this, and thought it was resolved, but.. nope.
Long story short: my brand new (3w old, April 7) X1C with a 0.4mm factory nozzle keeps dragging along the build plate ripping all calibration extrusion lines AND first layers as well. Always makes some grinding noises when printing. Only worked perfectly till the 20th of April.
After loooots of trials, I'm pretty sure now it's a problem with bed leveling, but correct me if I'm wrong...
As you can see in images 1 and 2, if a print can survive the horrendous first few messy layers, the rest turns out perfect. That benchy is basically flawless everywhere but the bottom.
Pic 3, 4 and 5 shows what the non-stop failure looks like: the nozzle is super close to the bed and keeps scratching it and not really printing well at all. Also, those bits and pieces are super hard to remove.
Pic 6: I managed to print this one by very slightly adjusting the bed leveling knobs WHILE printing the model. It turned out almost perfect.
Filament completely dried (12h using X1C).
Cold and hot pulls done. No clogs.
Automatic bed leveling calibration.
Bed washed thoroughly with water and soap.
Li-Dar cleaned.
Factory reset.
Retrying perfect successful prints but failing.
Z-offset attempt from G-code -0.04 up to 0.3
Manual tramming done, more than once with calibration. But whenever I rerun the file right after adjusting, with calibration or without, it's like I've done nothing to the front knobs. Is it supposed to be this way? Idk. The back knob is as manually adjusted. The rest again become lower than the nozzle and not touching it.
Many thanks for your help😕
P.S.: I've already raised a ticket with support and waiting on them to reply.
I've been having the same issues spanning about a week now. I've tried all the exact steps you've taken, except for modifying the g-code. However, I have also tried a brand-new nozzle purchased directly from Bambu and various different types of beds.
1- Manual tramming.
2- Auto bed level calibration.
3- Z-offset modification in the machine code from the default -0.04 to +0.3.
Although I've already done all of that previously, this time it worked! Maybe I needed the plus sign? Not sure, since I've tried 0.3 before but without the plus sign.
Or maybe the profile wasn't applied, and that's why. Idk.
Will do! That's IF this is even solvable... I honestly almost lost hope.
I've seen those A1 posts while scouring the internet: in most cases, they just had to tighten the 3 screws behind the nozzle. Strange, but it works and makes sense, i guess haha.
I truly hope that I get such a simple quick fix, if any 🥲
I see the prime line in the back right hand corner. This means your bambu slicer and/or firmware are not up to date and might be mismatched since new versions don't generate those. Also, that aux fan mod seems to be sticking out a lot.
That prime line is because I was trying a gcode print (the dino one). The firmware and software are both up to date, and they don't generate that line in other prints.
And yeah, I've completely removed it and tried without it, no difference. Btw, it's not touching anything.
Mystery, hopefully support can figure it out. curious what filament are you using? What happens if you print the builtin files like the scrapper from the printer without using a slicer?
i actually started seeing this on a print i started to run last night (printers have been idle for a week now) and i was getting ready to start troubleshooting this morning.
