Nice job you're doing zmajmr! That 220 looks like a great machine.
I have the older (v10) Dolphin program and had problems with Mach3 post-processing too. Fortunately, Andre over in the Dolphin forum here in the CNC zone is very helpful in these matters. http://www.cnczone.com/forums/dolphin-cadcam/ Hopefully they have a post that will work for you.
Just looking at your video, I think I saw that your downloaded version is v13 and the post you chose is v11. I don't think that will work.
ps: You're doing great with Dolphin...it took me a long, long time to get as far as you. I'm old & the light bulb is getting dimmer & dimmer.![]()
