I'm interested to hear what everyone has there Mach 3 Settings at. I did a search and see some old posts. Seems like it would all be figured out by now.
My machine is a turnkey mill, which I have been fiddling with to get it right. Everything is better, but seems like I could get better results. What makes me think this? Glad you asked. I have a cnc4pc speed controller for my VFD and when I went to tune it, I noticed it was already turned all the way up. The instructions also mentioned a setting way lower in mach 3. So something must be different on my machine config. No way would cnc4pc create something that is maxed from the start.
What made this all come to light, was that I had x axis moves that faulted all the time. This cost me a ton of money. Finally, Tommy and I went over the configs and changed SOMETHING to 10 from 15. Problem gone, but everything was out of wack. Basically Spindle speeds were messed up and didn't reflect proper speeds. I had to set all the pulleys again and that still does make sense to me.
Here are my config settings, please post yours. Any helpful comments as well could go a long way. Does anybody know a way to get faster/reliable rapid speeds? I can't get more than 130 ipm. Sounds fast until you have code generated for high speed machining.
