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

[PAULRO]

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

Ok well first makes sure Spindle is OFF. Type M5 in MDI. Check Continuity again.
If still got continiuty then Change active state (NO Tick) and Check continuity again. It should drop Off. Type M3 and it should give continiuty again.
If it does you are working correctly.

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

Ok Great now next step is to test on VFD.

So first set VFD PD002 = 0. We are just testing ON/OFF for now so control speed on the VFD Key pad.

Set PD001 = 1 Then Connect wires Back to Relay contacts and M3/M5 should start and Stop VFD.

DO NOT TRY Controlling speed yet.!!

[PAULRO]

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:
Pulley #1
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.!

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!

[PAULRO]

hi Neale, how do you control the 12 volt psu dropping out and the 5 volt kicking in?

[Neale]

I have a 2-way centre-off switch mounted on my control box which has an old pc power supply in it. That gives me both +5 and +12 selected via the switch - purely manual operation. My new machine (under construction for rather too long now) will use gcode switching via the motion control card; I'm not sure yet whether to stick to 5V or to add a manual override to give a short 12V burst at the start of a session or when first pushing water through the system. Once the pipes are full, the system is balanced and it doesn't need much to keep the water circulating (from a bucket at the side of the bench - never gets very warm but I'm not working the spindle very hard).
