Trying to get a better first layer. It seemed obvious that "First Layer Settings" is where this might happen. However I am seeing some weird behavior.
First, if I change "First Layer Height" to, say 50%, what I get is a thinner first layer AND I also get about half the extrusion thickness printed. In other words, instead of the lines being smooshed they are thin little hair-sized lines that don't touch each other.
I tried leaving "First Layer Height" alone and only changing "First Layer Width" to 125%.
The preview window shows the lines smooshed together as one would expect. However, the machine is printing thicker lines farther apart from each other. So, it looks like the actual G-code has lines that are 125% wider but also spaced 125% farther apart (or something like that)...which means the infill consists of a bunch of thicker lines that don't bond to each other.
"First Layer Speed" seems to work as advertised. I don't actually know if it is affecting anything else as the other two settings seem to. I have it set to 20% and that seems to be what I am getting.
Are these known bugs?
If not, how do these settings work?
How do I smoosh down the first layer, get the first layer infill lines to bond to each other if not with these settings?
I found the "Global G-Code Offsets" in the G-Code tab. I can use that to drop down the first layer. However, this drops down the entire part by whatever value I put into the "Z-Axis" field. Which means that my part becomes that much thinner.
Color me confused.
Thanks for your help.
