I’ve been struggling for two or three days now trying to get the filament to feed properly. The prints say it all, but the less obvious stuff speaks volumes. I mark my filament about ever 5mm and start extruding. You can very clearly see that it doesn’t feed, and when it does it has spots where it doesn’t feed. I’ve cleaned out the teeth on the feed gear. I’ve done my best to make sure everything is aligned. I’ve gone as far as using the 2nd hand filament feeder model listed in the stickied threads (mind you that thing doesn’t work at all, but thank god I pre-printed it). I don’t know what to do. Please help.

我也有挤出机的问题。在几厘米的适当挤出后研磨长丝，然后再次挤出。这将解释为什么您的灯丝不断地送入。

来自Witheriverse的市场灯笼送料器正在为我工​​作，但我不得不更换圆形的PLA垫圈，坐在轴承和步进电机表面之间用m3坚果。然后拧紧M3螺钉，该螺钉将轴承保持在螺母上并拧紧另一个，挤压灯丝，同时挤出，直到挤出机开始点击。找到挤出机接近klick并逆时针转动1/4的斑点。

拧紧保持轴承的m3螺丝对螺母的看法很重要，因为其他M3螺钉将力施加到除挤出机齿轮（偏移）的其他地方。这导致动量使得更短的M3螺钉倾斜。您可以通过用螺母正确拧紧它来减少可能的倾斜角度。（我希望这是可以理解的:slight_smile:)

< p >问题是,我只有这个打印机for about a month. I shouldn’t have to completely replace parts on the printer with second-hand\aftermarket parts to get it to run. It’s not old enough to need replacement parts already.

@Stefan_Muenchen do you have a photo?

Still not right but much improved. The filament does not line up correctly with the nozzle. I can feed filament through the feeder section wihtout much resistance. Once the filament enters the nozzle, it gets very tight fast. I ended up drilling through the feeder section top and bottom holes and super gluing the feeder tubing and nozzle tubing (inside of the feeder tubing) in the top and bottom of the feeder section. What I think is happening is that there is just too much play for the filament to move around after some use, that it can just pop off to the side of the bearing that is supposed to be pressing it against the feeder gear. I’m also finding that the filament feeder section cannot be tightened down. I had left it loosely threaded. I feel like the feeder section really should have been made out of metal instead of half HDPE and half PLA - if they’re not going to make those models public, which would have been the solution to all my problems I think.

That print failed. Sort of expected. I’ve never successfully printed without rafts on this printer. Trying again with rafts.

I had the same problem.

I tracked my issue down to the nozzle.

You should change the nozzle and see if the problem is fixed.

I did noticed the nozzle heater had a over temperature transient at warm up which could be a firmware bug and the actual source of the problem.

A reset and the heater temperature is behaving correctly again.

I had the same problem. In my case I could fix it with合适的丝状. I did some research regarding the right kind and alas it worked. I hope you find a solution!
