A10M - NO FILAMENT COMING OUT HOT END - NO GLOGGING

[Manu.B]

Dear fellow A10M users,

I have an issue with my A10M : No filament going out of the hot end. It's not clogged because I have cleaned it and finally changed it by a new one with the exact same issue.

I also changed the PTFE by new ones and check the connectors too. Everything seems to be alright.

I suspect both extruders not pushing enough the filament. I have adjusted the screws and cleaned the gears. It was working with under extrusion for a while. Now it’s not working again. I have planned to install metallic ones instead of the original plastic one.

Some help would much appreciated
Thanks in advance

Hi, Is your extruder motor working properly? Is the gap between the idler and the gear too large?

The 2 motors seems to work correctly. I also see the gears turning when the motors are working.
To check the space between the gear and the idle how do I do ? I need to disassemble the mechanism ?

Thanks

I have changed the 2 extrudeurs and its working better. I had to update the firmware to reverse the motors. I also need to adjust the step/MMS

I had also to change the Steps/mm from 340 to 100 due to the change of extrudeurs gears dimensions. It's really better now !!!
The issue seems to be the poor quality of the extrudeurs provided with the A10M....

Titan extruder is only solution to get stable printing quality for A10M. And dual drive too, of course. A10M need too much force when compared with single colour hotend.

You need to tight spring in driver. Turn screw to left by few turns.

My levers (both) are broken after few months, but I was print week before all levers that I was found for Titan extruder because I was see some crack when I was change spring. Now I have stronger spring (8mmx14mm) which work better than original and is really CHEAP.

(I was buy springs in many sizes about, but these are OK - maybe it fits to original lever too, description size is bad!). Titan springs are not needed anyway, they are often weak.

Hmm, see that item does not exist... I have 60 springs only, for few time it will be OK.

So parameters 8mm outer dia, 1.2mm wire, about 15mm length. Like standard-wide 20mm extruder springs, but shorter.
