Hi Tom
Thank you so much for your help and patience , with me on this project .
I was starting to doubt whether using a Kflop/Kstep/kanalog set up to retrofit a CNC mill would be possible for some one with no programming experience and limited Electronic knowledge.
But we have succeeded,, with huge amounts of understanding from you.
i now have 3 closed loop axis's repeatable to 0.004mm over 50mm and a working spindle
all the original front panel overlay buttons work for their original functions . Fwd and Rev buttons originally ramped up the speed as well as turned on the spindle ( i have some digital potentiometers around here somewhere, so that could be a project for my retirement :-) )
thank you so much for all your help
