Re: How to use "First Layer Settings"?

Sorry. Width changes the spacing. So, if you had lines that did not touch and you change the First Layer Width parameter both the extruded width and the spacing between lines increases. BTW, this is not displayed at all in the preview window. Regardless of the width setting the traces are the same s...

Re: How to use "First Layer Settings"?

OK, I'll go through some of these points and see what results I get. For reference, I am printing using a 0.8 mm nozzle. My z home position is set to somewhere between 0.10 and 0.15 mm using feeler gauges, not paper. My z-home limit switch is repeatable within about 0.0025 mm (0.0001 in). Finally, I...

Re: How to use "First Layer Settings"?

I've been using 100% but the results have not been consistent. My build plate is ridiculously flat for a 3D printer (I machined it flat on my Haas VF-2 industrial CNC mill)...so that's not the problem. There's some math voodoo happening somewhere that I don't yet understand. Not sure I understand go...

Re: How to use "First Layer Settings"?

When you reduce first layer height below 100% it also reduces the extrusion multiplier I believe. Use the global offsets to get more squish. I usually have my first layer height at 100-120% depending so to compensate for a bed that isn't perfectly flat in all areas. When you increase the first laye...

How to use "First Layer Settings"?

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. I...

Process, Profiles, Printers, Tuning, how to?

I am working with several printers. A few of them are the same model, however, a couple have different size nozzles and the other is setup to print ABS exclusively (enclosure, etc.). I am trying to understand how to use Process and Profiles in the context of running these machines as well as tuning ...
