how can I get out the PTFE TUBE of the ISOLATOR GUIDE?
I think the PTFE TUBE is not cut very good at the first time.
So my print will stop after one hour while no filament is transported any more.
Only klicking by the filament motor.
So I want to make a new try. But I’m not possible to get out the old PTFE TUBE of the ISOLATOR GUIDE.
Can someone explain how to do this?
Thanks a lot…
By the way: This hotend is one of the worst I’ve ever seen.
So bad for this printer…
Till now I regret to have bought this printer. Only problems.

Only klicking by the filament motor.[/quote]Your nozzle is probably clogged. If you measured it correctly, the PTFE tube is seldom the culprit.
Print at 190° for PLA and 220° max for ABS. Higher temperatures will clog the nozzle eventually.
To remove the PTFE tube, push it from above with a small screw driver or better a hex wrench (tilt it a bit to get it pushing on the upper edge of the tube). You’ll certainly damage it doing so.
Sorry for late answer.
But after writing this thread, I got out the PTFE tube. It was a little bit tricky but it worked.
Of course my nozzle is clogged!
My nozzle is blocked till I have this printer. It is now 15 months ago, I bought it.
Frst prints where really good. But after 3 months I went in problems. Nothing helped.
So I bought ne spare parts to set up a complete new hotend.
Same shit!!
Everyone here in the forum said: Only use Velleman Filament. So I bought it. Nothing!
Same shit. After short printing time - nozzle blocked.
Then I was printing with 190°. Nothing!
Same shit. After short printing time - nozzle blocked.
So, what can I do?
I will try to setup up the hotend completely new!
I had one of the first printers sold. I have a clogged nozzle from time to time but its doesn’t happen very often. And I still have the same PEEK and PTFE tubes. I replaced the nozzle because it was wearing off.
Apart from lower temperatures and retraction, lower the flow to 75%. Don’t use infills above 60% (most of the time 30% is enough).
I’m using E-sun filament and I’m very happy with it. Always got perfect prints with it.
It’s very important to keep your filament dry (especially PLA).
Also a clogged nozzle only once in a while, say three times a year. I am using Real PLA and PETG. One in the left and the other in the right nozzle so I don’t have to change between types of filament. Sometimes I use ABS in the PETG nozzle and then by hand, I push much more filament through the nozzle as it would by the loading command, to clean the nozzle.
A clicking extruder can also be caused by to little space between bed and nozzle, but that’s mostly only for the first layer.
A second reason can be that the Peek is not centered exactly under the tube fitting hole. I discovered that it does not center automatically and this can cause filament friction.
And by the way, this week my Isolator Peek broke spontaneously right above the nozzle screw-thread. I think the peek material becomes less strong with the permanent heath.
Made a ticket for this…
