Ignorance: Lack of knowledge. There are a lot of things I am ignorant of and will admit to but I know how to fix it.
You listen too much to your internal engineers. There appears to be the classic NIH syndrome.
You don't know much about MACH or it's capabilities. I agree about WINCNC and Flashcut (since I have sold retrofits to customers that own both those systems). They were just never crafted with plasma in mind.
MACH3 HAS THC FUNCTIONS BUILT INTO THE CORE ENGINE. If you would like I will direct you to the MACH3 Manual section on THC. Also the entire front of our 46 page manual covers MACH3 and THC operation.
I won't argue the technicalities of stepper VS servos. It would take a small book and on other lists it has been gone over many times. I have years of experience with both. It never was the source of rancor anyway. You made the statement that MACH only worked with steppers and I corrected you on that mis-statement.
So for the record. Is your servo loop closed in the software (where positional errors are sensed and corrected) rather than the driver electronics, and if so how in heck do you get loop response of multiple motors on a serial link?
I have been involved in Electronics (EE since 1973) and spent time in power design and power control (including motor drives and switching power supplies) and then software design and later systems integration and IT. I fixed CNC controls back when they used paper tape. I have been doing CNC plasma cutting since 2001 (when my dot-com job left me "available".)
You need to go back and read more closely about what I said about closed loop. I agree that encoders on steppers using conventional loop gain feedback techniques is lame but it can (and has) been done correctly.
You are spouting marketing stuff and it has little basis in reality. If you really want to get in a feature VS cost debate then let's do it. Your machine running your THC and software VS the MACH3/SheetCAM/Mp1000 combo.
List every feature you can think of and the cost of your solution and I can respond in kind. I know...let's do a comparison chart. If you want I'll even construct the chart.
Forgive me for not responding to the growth rate, and other red herring arguments. They have little to do with the core issues. I'm not a business rookie either but this is not the venue to discuss business 101.
