Let the fun begin !!! ???

[PAULRO]

my pump stopped running so i went out to get another ,this time i bought a WHALE 12VDC SUBMERSIBLE TYPE. it can only operate for 15mins max. at a time so
i will have to set a relay ...
anyway, i tried as suggested Jazz and still no joy. I set PD001=1, PD002=1, disconnected the wires to relay 1 ( run/stop) and tested with meter , i then tried to trigger the relays alternating between M3 and M5 on the MDI window but the condition of relays never changed. however i can go to outputs tab and toggle the relays on/off and will get a result. this BOB came with a MACH 3 PROFILE to be downloaded from the ZAPP website http://www.zappautomation.co.uk/elec...board-236.html
this should be unzipped and placed in the MACH 3 folder . i should then use the MACH 3 loader to select the profile but when i do nothing works . if i use the MACH 3 loader to select the profile i had set up ( GARAGE PROFILE ) i'm able to operate the motors , etc. but have no joy with the relays , pwm .

I am not going to interfere with what Dean is trying to get you to do as this is a very difficult situation when working from afar.
.
Please don't take this the wrong way But you are not helping yourself and muddying the water when you bring things up that are nothing to do with this problem. So try and work methodically step by small step and give clear answers to the questions asked of you. Just straight bullet points are easier to follow.
.
As a matter of interest when you use M3,M5 do you hear a click from the relay? ..Clive

I set PD001=1, PD002=1, disconnected the wires to relay 1 ( run/stop) and tested with meter , i then tried to trigger the relays alternating between M3 and M5 on the MDI window but the condition of relays never changed. however i can go to outputs tab and toggle the relays on/off and will get a result.

How did you toggle it with the active state or the Enable.?

The output Active state is not a Switch for toggling any thing On/OFF. It's a Logic condition that needs to be set so things can work correctly.
The enable is just that.!! . .Your turning the output off. So if the relay changes state then you probably have the Wrong Active Logic set and relay is coming on straight away and by disabling the Output it gets turned off.!

Set Active LO(unticked) and try M3/M5 again if relay doesn't change state(or Click) Set it HI(ticked) and try M3/M5 again.

Don't go Chopping and changing settings all over the place as it really makes finding faults difficult. Only make one change then Test.

i toggled the active state of the relays to see if mach3 could change the state of the relay from a non responsive state . i have them set back now to the folowing the run relay 1 is on constantly because of active high setting. if i input M3 the spindle will run at 250-300rpm . M5 stops the spindle again. the only relay to change state is the PWM dependant relay 3

[JAZZCNC]

Paul your not listening properly because if you'd done as I suggested then the spindle wouldn't start at all. And the speed would be controlled from the VFD using what ever speed you set.

You need to take a few steps back and deal with one problem at a time. Stop changing settings willy nilly because this makes the Job of helping so much harder. All this does is waste yours and my time by chasing false issues. I need you to only change one thing at a time then report what happens.

First all you need to do is get Relay #1 working. Forget #2 & #3 we don't need them so you can turn them off on the BOB and disable them in Mach3.

Straight away I see that you have the Wrong Pin number set for Relay #1. It should be Pin 16 not 14.
Pin 14 is for the PWM Speed control which I believe is working fine just needs setting up for correct speeds which can be done later. NOT NOW.!!

So to re cap Tell me which terminals your connecting to on the Relay.
Set Output #1 = pin16 Active LO.
Turn off the Enable for Outputs #2, #3.


Next the relay will have 3 terminals which are you connecting to.?

[PAULRO]

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.

[JAZZCNC]

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.

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!
