Faling continieus PLA stream

Post by Ramaisdrama »

Hey,

Friday I got my own working felix 2.0 at home and from that moment on I'm trying to print. When I'm printing the test 40x10 nothing is wrong, bud when I print larger objects I get the following problem.
At the start the printer and print are just fine, but after between 15 and 30 minutes the printer loses its grip on the PLA. I can hear the extruder wheel lose grip. The flow of PLA is then interrupted and I get gaps on the print. The longer the printer is working the bigger the problem gets.
I have tried to ingress the tension to the point the PLA can't go further, and that can't be the solution. I have also tried to play with the hot end temperature from 190 to 205 with no effect on the problem.
I had the problem with the PLA delivered with the printer and also with the PLA that I bought from a other company.

I don't think the extruder is blocked becose the smaller prints are just great, and when I extrude manually its seams like now problems. At this point I don't think something is wrong with te printer bud that I do something wrong. What's the best step for my to try now?

It sounds like extruder feed stepper motor stalling briefly, is it getting warm? the extruder Stepper driver may need adjustment.

..from the assembly manual for felix 2
"Over time the stepper drivers may become too hot. There is a self protection mechanism in the chip which will temporarily turn the chip off to cool itself down. It will protect itself, but this is off course unwanted behavior as it will give intermittent movement during printing"

yes you may be right there, also maybe check your connections for an intermittent connection.

@seaton:
The problem is solved, it was not to match power butt to few. When I view at the electronics with the manual, I observed the it was already lower then the manual. So the motor did not get enough power.
I now think that whit larger objects the system gets hotter, the head warps en the motor needs more power.

Thank you Seaton, I probably would not look at the power adjustment me self without your advice.
