Long moves with no printing but no retraction either

[Dale Eason]

I am using mattercontrol slicer and sometimes it will do a long non-printing move but it does not command a retraction. The extruder leaks a little during the move and can leave a little trail or a small glob at the landing spot. When it does use retraction it works just fine. I have turned retraction on everywhere I could find it. I also tried cura and it does the same Is there a retraction setting I may have missed? Do I need to adjust something so that my extruder does not leak? I',m printing SeeMeCNC ABS at 229 commanded but the extruder usually reports around 227 while actually printing.

Is there a setting to just turn on the layer fan for bridging in any of the slicers that come with mattercontrol?

Hey Dale,

A little bit of ooze just before the prints starts is pretty normal. Since I always print with a brim, it never affects the actual print.

Mattercontrol has a bridging fan speed setting under Filament -> Cooling. Just select the Advanced settings to see it.

Just to be clear I'm not talking about before it prints. It is printing and moving from one location to another with a long move but sometimes the slicer does not command a retract for various reasons. In this case the ooz can build op on the landing site.

I know about the bridging fan speed setting and have it set to 100% but my layer fan did not come on. It does come on if I turn it on manually with the Mattercontrol control widgets. So I know it can come on. However I did have max fan speed set to 0 in the fillament cooling advanced settings so I have changed that and will give that a try.
