Hopefully this one is quick. I used Estlcam to do a simple speaker mounting bracket and the elipse for the 6x9 and the outer rim cam out with “flat spots” where either the g-code didn’t tell theachine to arc, or the machine didn’t calculate the arc right.
Here’s a picture. I generated the tool path from a fusion360 dxf export of a sketch I drew up.
Any thoughts as to why these weren’t cut with arcs and instead had a linear move?
So you made a drawing with something, right? I know tinkercad does that.
Does marlin support arcs?
Anyway, it just looks like your arcs were broken into a series of straight line segments either by your cad or cam. I would suspect the dxf file first before estlecam or the machine.
Yes, Marlin supports arcs.
I think I figured it out… My “G” command was at the end of the line instead of the beginning. Maybe that caused the issue?
here’s a couple lines from the code:
X55.0252 Y63.1808 Z-8.0000 I52.5789 J68.6434 F2100 S24000 G2
X55.0252 Y63.1808 Z-12.0000 F480 S24000 G1
Haven’t seen that one before. If most of those commands were ignored, then one was good for some reason, then that is what you would get.
Do you have the gcode output set to Marlin?
I was fooling around with the order of commands that Estlcam output and accidentally put the “G” commands at the end of the line. Marlin didn’t output any errors strangely enough.
I might try it with a marker and the correct order sometime later and let you know the results.
My son-in-law is currently having exactly that problem with printing - I think the answer lies somewhere in a Fusion export setting (he’s exporting to .obj).
If you find it please let me know!
Did you look at the resolution you are exporting the files?
Here are a couple pictures that shows the difference in triangle count.
