Hello John and thank you so much for your reply. This is becoming a more of a quest or a mission to make this thing work properly, but at this point I am seriously thinking of ditching the Motor and Controller and either going back to the Hanging Dolly and Flexi-Shaft or splashing out even more money on a different Spindle Motor set-up.
The kit came from (You guessed!) Fleebay on
http://www.ebay.co.uk/itm/400W-CNC-Spindle-Motor-Kits-PWM-Speed-Controller-400W-Motor-With-Mount-Bracket-/221360481671?pt=UK_BOI_Metalworking_Milling_Welding_Metalworking_Supplies_ET&hash=item338a1ce587I must confess, the Motor is quite impressive, very quite at 6,000 to 8,000 RPM with very little run-out.
The specs on the PWM Controller are:
Support AC and DC input
DC Input : DC 15-160V
AC Input : 12-110V input
Support Current :10 A
PWM input : level 3.5-12V VPP
Frequency :1K-10KHZ(Particularly suitable for MACH3 spindle speed control.)
The Breakout Board is what was supplied with the Mill, which I have modified to take opto-couplers for the limits, e-stops and a touch pad. Pin1 from the LPT port as in the drawing from a kind person on CNC Zone is fed directly to the Speed Controller.
The Power supply is a 48v 10A SMPSU with enough power to blow your hat off.
As I said in the very beginning, it works fine I just cannot get it to marry up with the spindle speeds on the DROs its not a matter of being out a 1,000RPM or so, it is running about 75 80% out.
I really appreciate any help that anyone can throw at me; I cannot believe I am the only Muppet on the Planet to have bought one of these .
One slight caveat with the drawing I have posted is that if memory serves me the pulse train on the Pin 1 is negative going to where pin 2 on the ‘MOTO’ Port is High (5v) In the drawing Pin 2 goes to deck.
