Hi Everyone,
OK, I can reach the 10mm2/s , but at 9mm2/s there are occasionally problems. At 10mm2/s I can hear the extruder spring click every 4 seconds and there are small gaps in the print. The result sound pretty good for me.
I'm a bit confused. The extruder have always problems when printing the first Layer of a large surface. (0.3mm initial layer thickness, 20mm/s bottom layer speed, PLA at 115oC). The extruder spring clicks and I don't get a regular surface. The building plate leveling looks OK for me.
I thought the extruder is not strong enough to handle that - but after the test I would say it should. Any Ideas?
