Thread: Let the fun begin !!! ???
i have relay 1( OUTPUT 1)
set to pin 16, active LO. ( ticked) ( all other relays disabled. )
TERMINALS on relay
N.O CONTACT =FOR on VFD
COMMON= DCM on VFD

RELAY 1 is on . i metered accross the N.O contact and common and have continuity.

On the side topic of pumps - I use a similar Whale pump. I use 12V to run it for a few seconds to purge bubbles more quickly, but I then run it on 5V. Seems to circulate enough water to keep the spindle cool, and I have run it like that for quite a few 5-6hr sessions continuously with no apparent ill effects.
Good luck with the Mach3/BOB issues!

that's O.K. Relay turns on/off using M3/M5. i had to change active lo setting to set it correct way .

that's fine, M3/M5 starts and stops spindle
Ok great.!! . . . Now we can turn to speed control. But we are not going to connect any wires yet and stay with the meter.
First make sure Spindle output is enabled in Motor outputs and setup correctly. It should be set to:
Step pin = pin14
Step Port =1
Step Low active = No tick.
Next Spindle Setup. Go to Spindle control and select:
Use Spindle motor output = Ticked
PWM Control =Ticked
PWMbase Freq = 50%
MinimumPWM = 5%
Next go to menu Config/ Spindle pulleys:
Minimum Speed = 0
Maximum Speed = 24000
Ratio = 1
Now set meter to DC volts. Put Positive Probe to FIV and Negative Probe to GND on XP24. ( You will need 10V from VFD connected to 10V on XP24 but leave ACM & VI disconnected)
With Spindle off (M5) you should have 0v on meter. Check this first before doing any thing.
If Ok and 0V then type M3 S12000 in MDI and you should read a voltage around 5v try this and let me know.!

0.0 volts with M5 , as expected.
0.03 volts with M3 S12000
