General Mach Discussion / Re: Getting DRO values out of Mach3
« on: December 04, 2013, 07:01:22 PM »
Hi Rich and Gerry,
Thank you for your answers.
Rich: On not having the proper tuning on the steppers I can only say that they are the factory Tormach settings and they are apparently conservative. These "loosing position" issues happen mostly under no load and particularly when there is a tool change in the G-code. But it exhibits something similar under two different CAM programs.
I thought about upgrading to either a servo system or Tormach multiphase steppers, but the latter would still be open loop.
Gerry: I am aware of that board, probably I should ditch the existing hardware and go for it. I thought my idea would be simpler to implement.
Unfortunately you didn't know how to get the DRO values out, but I appreciate your help.
Thanks
Attila
