Filament change very difficult, tips?

Postby Korni » Thu Jul 19, 2018 4:53 pm

Hello,


I find the change of the filament on the Pro2 + very difficult .... because the Pneumatic connector / fitting are very unfortunate (difficult to access / visible).
I hardly get the filament inside the filament guide tube and first I have to pull out the filament guide tube to push the filament through the Pneumatic connector / fitting and then put the filament guide tube on again.
The Pneumatic connector / fitting (inside) in the printer is difficult for me to see (slight visual impairment) and therefore with every filament change an immense effort, also have the filament guide tube's already suffered from the permanent pull out.

Do you have any tips / tricks to facilitate this?
Danke

I don't have a pro2, so at the upper black deck interface, I assume it has the same pushfit connectors as the previous N series because this part of the frame is universal. I think your problem is your guide tubes are too short. The fix on mine is #1 upgrading to Capricorn brand super slippery PTFE based guide tubes for less friction and also making them longer so they not just extend through the top deck and pushfit, but actually extend down to the side of the spool it's feeding from. By having a longer tube- no more hunting to load the end as you described.

Jetguy has is right. On my Pro2 the tubes extend about 10mm below the inside top edge of the filament door frame. I just feed the filament into those and it's already on its way to the extruders.

With the original PTFE tube guides, or even longer ones?
The original ones seem to me like Jetguy writes, but too short?!

Mine arrived with the longer tubes in place as well as an extra set of tubes. All stock for me.

Oh, did you have the kit that included the gloves, feeler gauge, cleaning rods, etc. ? That box had an extra set of tubes in it for me.

No extra tubes, no 8mm socket wrench. Other pieces, yes.
