When I push the print button in the Repetier program the printer (K8400) will start.
After a few seconds the printer stops completely for about half a second/second.
And start again to print the object. No more stops again.
What’s happening, I checked the cables etc.
Since I don’t know anything about which printer you have or what kind of computer you are using this is just a pure guess.
At the top of the screen in the software there is a button “Show Filament” try clicking this to turn it off.
Some video cards can not deal with the graphics and cause the printer to stop for a short time and then start.
Sometimes it will post an error in the log area other times it will not.
Thank you for the reaction. I have changed the filament setting in the Repetier program and the printing was succesfull.
No stops during the printing.
It is still remarkable stops during printing because over the last year there was not such a problem.
First I printed a object again with disable show filament in the Repetier program.
In the meanwhile still using the computer for browsing the internet.
After 10 minutes the printer stops running and start again. The picture shows what happend.
The brim (first layers) was already printed see point A.
The printer starts again removing the start to point B.
As you suggested it seems to be that maybe the videocard will affect the software/printing.
I changed my videocard two month ago.
After this printing was killed I’ll print the same object but wthout any
use of my computer. The object was succesfull printed. So maybe the videocard.
Once again just a guess.
Are you watch the temp of the extruder?
Mine was doing that and I noticed the temp was dropping the printer would stop when the temp came back up the printer would start again.
Check the wires to the heating element make sure they are tight.
While you are in there you should check all of the wires and make sure they are tight.
The skipping steps maybe a loose screw on one of the pulleys.
Well It could be a problem with the Z axis as it could be dropping a bit causing an under-extruded layer. Some people have had there stepper motors over heat causing similar issues. Or could need a good clean and grease.
Is the problem only on this model? Have you looked at the model in X-ray mode to see if there are any issues shown in red?
230deg seems quite low for ABS, I don’t print with ABS but its normally printed around 250 - 260 from what I have seen.
The PTFE coupler needs to be very straight or it will not sit flat against the nozzle. this can cause a few issues. I would suggest that you head over to 3D Solex and replace it with a High Temp coupler that is more suited for ABS.
