Hi Joe,
I already had Dolphin for lathe and mill, but was only using it for the cnc router. I got it to do the usual turning, profiling, grooving stuff, and with the revised PP, also single-point threading and rigid tapping. (Note that I mainly use CamBam for most 2.5D stuff on the router, as I really like it.) My experience was that the evaluation version of Dolphin worked the same as the licensed version, except for the expiry period, so the issue may be something else?
Attached for your information and use is the latest PP file for Linuxcnc lathe I got from Dolphin. Note that I have changed the file type from .ppr to .txt, so that I could upload it to the forum. You will need to change it back to .ppr to use it.
Cheers, Steve.
