Hi!
I am having a problem after changing operating system on my computer that is used for running my CNC. Before installing Windows 7 32 bit I had an 32 bit XP installed. Program used for running the machine is Mach 3. So i decided to install a Windows 7 on this computer. I also reinstalled Mach 3 and copied Mach3Mill settings file into the Mach directory so all the settings will be the same as before. Everything work but my motors are having problems. They are lagging and loosing steps. One of motors didn't even want to turn. I was experimenting a little bit and I changed the values for step pulse and dir pulse from 0 to 5 and suddenly motor started working. But all three motors are still lagging and loosing steps. What could be wrong? Is it the Windows 7? Because everything is the same except the operating system.
Thank you for your answers.
Boris

Talked to a friend that is in the "know". He said mach3 does not like Win 7. He said "too much added junk on that OS. " He said Mach 3 likes XP and you should stick with that. You know if it ant broke, don't fix it. Good luck, Scott.
