complete disaster upon coming home…
came home to this after a print.
heated up the head…got some off but the hardening plastic had wripped off the nozzle locks and broke the plastic…er…fork things in grey on one side as it kept squirting out the filament. Im not happy to say the least.
im trying to contact bambu…it wants the log files…i go to where it says clik the log file in question…and thier site says its not a log file.
Anyone able to help?
Bambu has good videos and instructions to follow in that situation.
Get a quality 1mm hex wrench! The one that comes with the machine is garbage.
It’s not too difficult but it takes patience and time.
Unfortunate that you [seem] to have broken the filament cooling fan (the grey “fork thing”). The fortunate thing is that replacement parts and consumables (like the cutter blade) for the extruder are inexpensive. Your time spent
Prepare to spend a few hours with potential for frustration in the disassembly and reassembly job but think of it as time well spent as the next time–inevitable–it will go FAR more quickly.
These blobs occur early in the printing process when the object is just a few layers thick. If these critical layers do not adhere then a section lifts slightly and gets caught on the extruder while it is still small enough to be caught and held as the extrusion turns to the blob that ate the head.
Also be very cautious when attempting to print a number of identical items simultaneously. The conditions that form a highly effective adhesion layer.
Clean the build sheet scrupulously and be certain to rinse, rinse, rinse!
yea…its gonna be a nightmare repair. Bamu is sending me an entire new hotend so i can fix it but my skills in this area are horrible. My buddy i work with is into filment printers and ive asked him if he has the skills as he builds electronic stuff too.
Now for the learning moment: This almost always happens when your print becomes dislodged from the surface early on in the print, then because it weighs so little, it literally rides around on the hotend, growing.
Mitigation 1) Check the printer at like 15mins into a job. You can rescue this real easily if you havent squirted too much plastic. 2) Check your build plate cleaning/glue regimen. I like: Hot water, dish soap, scrub with NOT the same one you use for dishes, dry with clean non-lint cloth. Renew with isopropyl->wipe->hairspray every 5 or so prints. Dont touch it with fingers or elbows (Or if you’re an idiot with ham fists like me: I just assume the outer 2cm of plate is dangerously dirty, unless I have cleaned it right beforehand)
This is the true reason why people are so careful about clean plates!
