On my Handibot I typically cut HDPE at 3 inches per second with an 1/8" bit. I take light passes, usually around .04-.08. I have the router cranked up to about 75%. On my large CNC machine (full-size ShopBot) I cut HDPE at 4.5 IPS, .25 depth per pass at 18k RPM.
Thanks Eric, for the rapid reply. I will try those numbers on my Handibot. I think I had mine set at too fast a spindle RPM and feed rate too slow. Regards, Wazza
Good luck! Also try a single flute upcut bit like this: www.amazon.com/LMT-Onsrud-63-610-Uncoated-Diameter/dp/B001VY3664/ref=sr_1_1?s=hi&ie=UTF8&qid=1499288912&sr=1-1&keywords=onsrud+upcut
You've got to keep a good chipload going. I'd say go 3 inches per second with a 1/8" bit doing 1/16" passes with the the router at 75% speed and you should see good results.
I use SketchUp to design, and then I use Vectric VCarve/Aspire to make the milling files. Vectric software runs on Windows, and I'm running a virtual machine with windows installed to do that.
I am using my handibot for a similar application and need the same code that you use for the zeroing and the 1in move from z zero. I hate to ask but is this code something you would share?
Great mods Eric, has given me some ideas for my own work. you don't happen to have the link for the T-track do you?
Hi Eric,
Can you tell me about the cutter you are using on this HDPE, as well as speeds and feeds?
Many thanks
Wazza

Hi. What kind of software are you using on the mac?

I can share the code with you for sure. Head over to the Handibot forums and ask there. I'll post it.
