Flexible filaments are commonly used where preventing impact damage is key, such as in phone and other electrical casings. First try a "cold pull". Seems this tube is getting too hot, causing the PLA to soften and expand. The layer height has a significant impact on 3D printing. For instance PLA printing at 210 degC gives a high risk on filament jams. With standard filament, brass nozzles can hold up pretty well, but after a few hundred hours of printing, or from scraping on the build plate, a change can be in order. Most 3D printers include a shortcut of PTFE tubing leading in the hot end, even those with direct drive extruders. We recommend branded Capricorn tubing for the best results. Use a heated bed at a lower temperature, of between 30-50C, and an extruder temperature of between 235 and 250C, with 240C+ often working best. filament not extruding In this case, the motor controllers usually have a thermal cutout which causes the controller to stop working until the temperature goes down. Some filaments do just clog - I have some older colorfab filaments that I just use to print The procedure to follow is rather simple: If the needle method didnt work, try the cold pull. Enough friction and the extruder wont have enough torque to push the filament through enough for it to pass through the nozzle. A poor quality filament and involuntary contaminants lurking inside the material can accumulate and clog directly inside the nozzle at random intervals. The dirt and debris can also melt then stick to the inside of the hotend and nozzle further cranking up friction. Or a failed motor. o and I cleaned the nozzle few times even tho wasnt dirty. Failure to do so can cause the cooled part of the extruder to become hot, and the filament will soften or melt too early, causing jamming. 2) Spread a thin layer of glue on your print surface (regular paper glue stick should work fine). The filament is heating up to a sufficient temperature for it to melt enough to extrude and pass through the hotend as required. Damaged, Dirty, or Poor Quality Filament. A broken wire on a stepper can easily destroy a driver chip by creating high voltage spikes as the stepper is connected and disconnected (the same damage can occur if you manually disconnect or reconnect a stepper motor while the printer is powered-up). For flexible filaments on Bowden machines, its not recommended to go faster than 20mm/sec. WebIf the printer is not extruding enough, the extruder may be clogged.
