UMO+ not retracting during travel moves?

Recommended Posts

Hey guys, I have a weird problem with my UMO+.

For some reason, it seems to be retracting during some moves, but not others. For example, if it goes over an open spot, it retracts, but doesn't retract during travel moves over existing material.

Settings:

Layer height: 0.1mm

Initial layer height: 0.3mm

Print temp: 190c

Build plate temp: 60c

Enable retraction is checked

Retract at layer change is checked

Retraction distance: 10mm

Retraction speed: 35mm/s

Retraction extra prime amount: 3mm³

These are the only settings I have enabled within Cura's advanced settings.

Any ideas?

OK, so further tests seem to favor faster travel speeds.

At first. I had it set to 100mm/s, and setting it to 150mm/s has improved things a bit.

Also, I found one of the belts to be loose, and a belt pulley not even tightened down. Woops! Will test further with increased travel speeds. I might even try a lower nozzle temp.

Seems like a faster travel speed means the filament doesn't have a chance to ooze out before it gets to the next spot.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
