Welcome to the SeeMeCNC Community

For the most part my prints are coming out well, but i am having problems recently regarding supports. They are coming out like a tangled mess, mainly on fine printed layers of .100 mm. Any ideas what could be causing this and what I should change setting wise. I know i have some retraction issues to work out still. Could that be the problem.

Here are my settings: (Using Matter Control)

Layer Height: .1 mm
First Layer: .3
Perimeters: 5
Top & Bottom Layers: 5
Infill: 30%
Speed 30 mm/s

Support Type: Lines
Amount: 45 Degrees
Pattern Spacing: 2.5 mm
Interface Layers: 0
x & Y Distance: 1 mm
z gap: 1 layer
Support Material extrusion .6


Here are some pics:

It looks to me like your Z zero point is off a bit. The first layers shouldn't have that big of a gap between filament tracks. The support may not be sticking to the bed.

Along with what Gene said, it also looks like your extrusion percentage for supports is at 60% (or .6) which could potentially be under-extrusion for your supports, but that's really just a guess.

I appreciate the help guys. Gene... do you think it needs to be adjusted lower or higher? I calibrated it using a feeler gauge to the same specs that SeeMeCNC does their Orion machines at factory. With that being said, seeing as it is still by feel it could be off. I am also using a Buildtak surface and re-calibrated it after putting it on, so I initially thought it may be that the Buildtak doesn't let first layer smoosh quite as easily as the glass bed does.

It's too high.

Ok thanks. I will recalibrate it again. it is probably my horizontal radius setting so i will adjust everything again and see if that fixes it.

I appreciate the help.

No, it's your Z-zero point.

Ok my bad. I was thinking backwards... but if I adjust my Zero point then I will also have to adjust my horizontal radius after, correct?

Nope. The z zero point basically tells the machine that when it hits the end stop switches, it's exactly nnn.nn from the surface of the bed.
