Working on my first cnc project. Made it in foam first to verify and test my workflow and tool paths. I need to optimize the code as this took 9hrs on the machine. And I didn’t even do all the county lines.
Trying out Aspire.
@Nicholas_Lanham have you used any of the 3d caving patterns? the version I have does not have them.
9 hours? I know I’m spoiled, but that seems really really high. What was your feed?
Unless you stood over it, that is nine free hours (no labour cost ) but I would also want to get it down a bit 
@Peter_Fouche I did watch it. I had beer so that was a plus.
I get antsy when I have to cut below 700ipm…
@Joseph_Fitzgerald I honestly don’t know what my speed/feed was. it was my first cut/project. I just fired it up and then adjusted the speed that seemed like my machine could handle. I think I settled on 400. My system is setup for mm, so I’m assuming it was 400mm/min. that seems kinda slow though… I’ll have to perform some test before I do the final piece. It’s all new to me. haha
That puts you around 15ipm. You built the machine? Could be inches, depends on what you were doing. 15 would probably burn that foam. Keep us updated
@Joseph_Fitzgerald yes, I built it. cobble pieces together from many places. it is my version of the Openbuilds OX.
I used a 90deg v-bit for the carving and a 1/4" 4 flute down cut bit to cut it out.
I am using a Dewalt 661 as the spindle so I don’t know spindle speed.
