Hi From MidCoast Maine

The fun of Maine in the winter... temp when I got up this morning was about -5 F and while I was getting set up to do some test printing I heard running water. yep it had warmed up enough to thaw pipes that had frozen and broken in about 6 area of the basement plumbers are here now replacing the broken pipes (actually in 2 cases copper pipe fittings that had pulled apart in heating system lines) so between that and the mess my time for printing will be rather restricted today...

pipes broke in the same area about 10 years ago but I thought we had fixed it but that break was in another line it has been down to -27 f several times over the last 10 years with no problems.... ah enough venting.

I thought Ohio was bad in the Winter, you have us beat by a mile!

You can lessen the "zits" by slowing down the outer loop speed, if your slicer lets you do that independently from the other inner loops. (KISSlicer does.) Try 25mm/sec. Coincidentally, that's also an ideal retract/prime speed.

Also printing perimeters from inside -> out helps manage surface artifacts. However, dimensional accuracy is better printing outside -> in. Since I need BOTH nice looking and dimensionally accurate parts, I print inside -> out and compensate for the dimension in either the model or in how I slice the part (i.e. tweak the extrusion width in KISS so it does not equal the nozzle diameter). Slowing down with inside -> out also improves dimensional accuracy so I find that I don't have to do much tweaking on many parts.
