Please have a look visually on it to respool in such a case and fix it. Lines might slip off or are wounded unevenly. Sometimes spools are not properly set up. It can happen if a drive unwinds in an uncontrolled way so we have to wind up the whole line again. It quickly happens that a lines is not correctly mounted anymore. Before printing check all 6 lines at the ABC frame anchor points another time. We risk to destroy the lines on sharp edges and we ignore the calibration we did before spending a lot of time. If one or more lines do not correctly seat in their bearing grooves we might get into big trouble because this will modify the line length(s) (anchor positions). To have a smooth and easy way to let the effector "fly" to the ground you can use /opt/sms_modes/sms_zdown.sh script Use a permanent marker to draw a dot on the screw. Tightening is turning against clock direction, losening the opposite way. If we tighten grinding will be to heavy, if too lose the filament is not pulled correctly. We use 5 rounds to fix the filament string.
REPETIER SERVER REQUIRING ACTIVATION FREE
allow the dangling filament string to have some free windings above extruder for the first layer.So no chance to deal with 20 kg spools right now. There is not active filament feed system present yet which is required to support the guiding. If you do not respect weight limitation it you will get failing prints. I also tested 1kg, 2.3kg and 4.5kg spools which work well without any doubt. if you use massive spools note that the printer cannot pull material from spools which have more than 6 kg of total weight (tested with a 8.5 kg roll of Redline Filament with 1045 grams of raw spool weight).This is much better than using the inner mounting hole of the spool
Use construction where filament roll is kept on two shafts which can rotate freely. If the extruder is fine you must be able to easily push filament through the complete hotend until it leaves the nozzle.Ĭheck that the filament spool can move with ease on it's mounting platform (roller frame). Then we have to unscrew the assembly to remove old filament pieces and small flakes maybe. In this case it is not possible to push filament through the heated hotend - wether by hand nor by using extrude command. The Aero Extruder sometimes fails to extrude filament because it is clogged. Use some old cloth to the grab old filament when hotend is hot enough. Cleaning also gently helps to better calibrate the nozzle. Otherwise unneccesary fumes from old sticky PLA might get into air. Clean the hotendīefore you print please check if the nozzle is clean. Hardware pre-flight checks (filament guiding and extruder)
