Hi, I hope you can help me. Buy a dms dp5 printer. I put it into operation. The axes and the hot end work well and the extruder also works well. The problem I have is that the filament does not reach the hot end. I never printed anything so it can not be stuck filament. What I can do? I am looking forward to your response. thank you very much Attachments:

Is the extruder turning, is it hot?
It's a long way from the extruder motor to the hot end, maybe you haven't pushed enough. When the machine gets hot you can squeeze the lever on the extruder and manually push the filament by hand just to see if any comes out.
You can also run the motor via the control by pushing the control knob in once and turning to "Prepare" -> "Move axis" -> "Move 1mm" -> "Extruder" and turn the knob until you start seeing filament.

I've done this before. remove your bowden tube from the hot end(you have to pull a little slack through your extruder) and pull out the end of your filament out of the hot end. Cut the tip at a 45 degree angle, and push it into the hot end with your hand. There is a little lip where the heat break meets the nozzle and filament likes to get stuck right there. Wiggle and jiggle until it slips in there and you can push filament out the nozzle. Make sure your hot end is up to temp. Then after its extruding, you can push through your excess to re attach the bowden tube. I do this every time I swap filament on stock. Once it's in all the way, it's all set until you swap filament

Hi, thank you very much for the answers.
I think the problem is in the heatbreak or the heatsink because the filament does not reach the hot end. never printed because I just bought it. probe introducing a rod of 1.75 and does not reach the hot end. I should disarm and notice what does not allow the entry of the filament to the hot end, right?

If the filament gets stuck on the inside edge of the heat break it may cause the filament at the hobbed wheel to wear down so the wheel just spins and the filament does not move. Have a look at the photo, if the filament becomes worn down at the red arrow you will need to cut it like 3dprintingmeathead describes and reinsert it back into the machine. If everything is working like you say it is then at some point the filament has to start coming out. Attachments:
