Not sure this is the right forum for this post, so if someone could point me in the right direction for the Denford Orac / Mach 3 spindle calibration posts would be greatly appreciated!!
I need to know how to set the indexing and calibration for a Denford Orac Metalworking Lathe that i've converted to CNC controllable on Mach 3 with use of a DIY CNC PCIcard system bought online.
I have the X and Z axis working correctly, but need the spindle to work, so to be able to use it to its primary function!!
As i understand it, mach 3 sends data to the spindle, the spindle interprets it and sends the signal back to Mach 3 as the new values. At present it is not performing the right values as im telling mach 3 etc. (although probably more complicated than that)
So i want to know how to calibrate the spindle, so that 1 rev at 50rpm is as i tell it.
My understanding and knowledge of Mach3 is limited, so please explain things as idiotproof as possible please!!
Thanks very much
