Problems with UPET Material....

Recommended Posts

>i put layer 0.3 because when i do 0.2 there is not coming enough material out off the nozzle

With a 0.3 layer you are asking the printer to output more material, not less, than with a 0.2 layer.

So if you have underextrusion, not enough material at 0.2, it will be worse at 0.3, not better.

Try 0.1, and/or print slower, this might help.

Hello all,

XT have given very good result fo me so far on most of the prints.

Only on a very challenging print when the nozzle has to go from different place very often without printing much in between the retractions make the filament to worn out and flatten down. At one point the filament cannot be driven forward anymore. Actually I tend to increase retraction length to reduce stringing, which may cause the issue.

The best thing to do then is to change the material, unload it, cut the 0.7 m which is corrupted (with indentation marks) and then re-introduce it to start with a "fresh" filament.

It worked perfectly well for me.

May be the pressure on the feeder notched wheel is not correctly adjusted for UPET.

I print at 50 mm/s with 0.1mm layer, 240 deg C, 110% flow.

Regards

Ludovic

The print you are trying to do is a very difficult one, especially on that scale.

If you are still working out the details for printing with UPET, I would suggest you use an easier model with less retraction etc.

With bigger surfaces it is easier for you to detect if you are closing in on the ideal settings.
