I LOOOOOOOOOOOOVE my new X1 Carbon. I have printed so many things. I have been trying to print cover plates for my vents and due to the excessive heat at the vents, I am printing the covers with PC Flame retardant.
Each print starts out nicely after I entered all the proper settings and environmentals like no fan for certain items as cool down will cause warping.
Regardless what I try, I always end up with warped covers. Anything above 4mm in height gets screwed up.
I have tried a corner clamp from thingiverse, but both popped off and the force seems to be way too high from the warping.
Questions:
any ideas on how to prevent this warping? I read all the best practices with heated chamber, etc and if I open my door for more than 1 minute you can see the warping occur. Leaving the door closed results in bad prints for anything above 4 to 5 mm. Suggestions?
I tried to use a glass bed, but I don’t know the settings. Yes, you can click ignore on the missing identification, but the print doesn’t stick even with glue or Magigo which is THE recommendation for PC-FR. Any guidance? As it was hard to find a 255x255 glass bed see here Amazon.com
Can you give us some more insights about your printer settings?
Chamber fan running? → Should be off
Aux fan running? → Should be off
How much part cooling fan? → as little as possible as much as needed
Bed temperature? → max. Temperature the Bambu can give you
For PC you need a high chamber temperature and a high bed temperature, no fans running apart from part cooling fan - but only as much as needed.
Also, PC doesn’t like it to be printed too fast. I print PC with max. 100mm/s.
The easiest way to reduce the speed without fiddling with the speed settings is to reduce the max volumetric speed in the filament settings. With a 0.4 Nozzle 100mm/s is around 8mm3/s.
Right now, I am trying a different approach. I modified the STL file for an existing clamp and I made is low enough for the printer nozzle to go over it as long as I don’t print all the way to the edge.
It seems to work right now. The print is not finished yet but it looks promising as those clamps hold the magnetic plate in place and this avoid warping.
