Extrusion stops too early

[mentaluproar]

Retraction, coast and wipe are all at zero and I still keep getting prints like this. I cannot figure out what I’m doing wrong. https://imgur.com/gallery/4jTyD

Attach the factory file for that part to a post....and someone will take a look at your settings.

File menu.....Save Factory File.

tada!

I can't comment on temperature....as I'm not used to ABS as a material. But......why have you got tall vertical sections with a single perimeter and absolutely no infill?

I would change to 2 perimeters at least and add an infill of around 25%. And up the Outline Overlap setting (in Infill tab) to 75%. That should stop the vertical walls being ripped apart by the total lack of substance and support!

I’ve done that before and it made no difference. Doing it this way let’s me try different settings to fix it without wasting filament and time.

I was using a wider nozzle too, the the layer heights can be taller. I normally use PETG but I had ABS loaded and it had the same issue so I didn’t bother changing it.

Speeds: 150 mm/s but adjusting speeds below 10 sec / layer 10%, that makes no sense. For this object the print speed will be mostly 15 mm/s. Set it to 40 - 60 mm/s and deactivate the adjusting option.

Temperature 260 °
If you are using a hotend with PFTE-tube, it will be gone. PFTE is impatient to more than 250 °.
If not, the temperature melts the material and this will clogging the tube.
ABS needs 240 - 245 ° max.

Layer Height 0,25 mm is very ambitious for a 0.40 mm nozzle. Try out 0.15 mm.

The nozzle can't find a way backwards when you use only 1 perimeter. That will interrupt the layers print to go for a new start point.
I don't know what happens with a activated retraction but a zero distance and +0,20 mm restart

Cooling:
ABS normally needs NO cooling but the times of strong warping are over. I print it with 10 - 15% cooling but important, do NOT blow directly to only one point. The cooling must be like opening a window but without any cross ventilation.

I'm trying those settings now. So far, the infill does not look healthy.

[mentaluproar]

Well, it's better, but still really screwy.

I do not know the proper temperature of PETG.

I think the problem is that the speed is too fast.
There is a possibility that the molded object is thermally collapsed because the movement speed of XY is too fast, the extrusion of the filament can not be made in time or the cooling time is insufficient.

Prepare small test parts and print at extremely slow speed. Is quality going up? If quality is bad, there are other problems.
If print quality is good, you can gradually increase the speed.

My default printing speed is 50 mm / s and the outline is 24%.

This is ABS still
