Currently running three unipolar Nema23 Motors on a Marchant Dice Router the size that was suggeted is 190 oz and that is what I am using. They are rated for 6.75V 1.5A. Their ID is 23HS8603. They appear to be a Motion King product. I have them set at Mach3 tuning of 250, 100, 6 and Y/Z are running fine but can loose steps here and there. The break out board is Stepperworld FET-3 Dynamo and is now responding quite well to the set up as far as power though heat is still and issue (more from the FET's on board than the resistors, serious cooling blades on them:D). So my question is how do I up the speed? As Kevin states that 190 oz is the max you should use on his machine.
Buy better unpolar motors (like the broad spectum torque holding of unipolar)?
Go to a chopper board for the BOB? This being to hopefully get better signal quality from the board.
Any suggestions would be helpful. As now that it is running to a degree would like to get it to the point where it can cut and do work.
