Prolight 2000 WinMe and motor speed control

Hi Rob and Others
I want to get Win-Me working for the PROLIGHT instead of DOS
do you run from a desktop shortcut
and what setting do you have been along time ago (15 years)

everything is working good with the prolight
I found out why I have a loss of power under load
after I called intelitek and minarik (PCM21000A the speed control board)
DC motor magnets get weaker from use and time
also speed control needed adjustment there is 5 pots on the board
tested the volts from motor wires when running max speed
adjusted the SIG ADJ and IR COMP
it works almost as it should

SIG ADJ is max speed volts (Was 10v low adjusted to 90V)
MIN SPD only works in manual mode (Did not adjust)
MAX SPD only works in manual mode (Did not adjust)
TORQUE or current limit factory set at 120% of maximum drive current (Did not adjust)
IR COMP to maintain set speed as the load changes (adjusted THIS WAS IT now works)

and the motor pulleys are stock 40G motor - 30G spindle the belt 70G pitch .200" XL (they measure grooves)
ordered new motor pulley 36G and belt from SDP 5400 to 4800 RPM
I will have to adjust the speed file in PLM2000 folder (SPINDLE.MAP).

Megclay, your ME settings are the same as mine. It has worked out fine for me. The test of the memory management is to load a really large NC file. I have loaded 35,000 lines without splitting. Another RcGroups member reminded me to check the brushes on my motor, and servo's. Haven't got to it yet.

Thanks Rob
I will try the large file trick
I ordered new brushes and installed them
my old ones are still new
maybe .02 shorter
