Hi jossa,
Yes JP33 Pins 5,6, and 7 are the KSTEP Analog Output pins.
Apply KFLOP's +5V to JP33 pin 5.
(That would be the 5v found on JP33 pin 25? or does it have to come from kflop?)
Apply KFLOP's GND to JP33 pin 7 and also Spindle CN17 GND
(also JP33 pin 26?)
Then JP33 Pin 6 will be a 0-5V signal that you can connect to the Spindle CN17 "Input".
Configure KMotionCNC | Tool Setup | M3-M9 | S = Exec Prog Thread=2 Var=1 <>\C Programs\KSTEP\KMotionCNC\Spindle_S_KStep.c
(that is a prewriten program in a DIR on my computer, where do i load that after configuring it?)
Check with a Voltmeter (DC Volts) to JP33 Pin6. Commanding in KMotionCNC MDI S100 should read about 1.0V, S250 should read about 2.5V, S400 should read about 4.0V. etc.
Yes there are two "Relay" driver outputs on KSTEP that can be used to "switch" the +5V signals like Start/Stop and For/Rev to GND. Try connecting the Spindle Signals to the Relay + and the Relay - to GND.
Toggling the Relay Driver IO (KFLOP IO 0 and 1) as described here under Relay Driver Outputs should activate the signals:
Using KStep
(ok i see.. that is a low amp "Relay".. i will try to get a answer from the factory about the logic, and hopfuly i can use that, if not this is my last option.. what should i ask them about the logic circuits? voltage levels and anything else?)
HTH
