Attachment 3855
This picture shows you using pin 7 & 8 to get a voltage
So you cannot use pin 8 to turn on the relay
Phil
Just to clarify, do you have an additional relay for controlling the spindle on/off?
i was wondering about the "8" being there
i normally use pin 1 for the speed signal and pin 14 for the spindle go.
Pin 7 should be getting used to produce the voltage, via the Step terminal on the V3, and Pin 8 should be controlling the relay on the V3 via the Dir terminal.
You should then be using another pin to another relay to turn the spindle on/off.
i'm sure there's an enable on the gemini, you can use the second relay to control it.
one point worth mentioning, the control of the contactors is 240v mains. This can cause a lot of noise, so it may be worthwhile having a low power relay that is switched by the v3 relay sited by the contactors to switch the contactor.
This way you don't have mains on the v3 board.
this was the aim, i am gonna sort out another relay to turn the spindle on/off.
ive got a mulitmeter zapping out the relay contacts NC and C, its showing closed circuit, when i press "spindle" the BOB lights do something but should the relay switch over to NO and C? this creating an open circuit and the multimeter show nothing at all
they way to check is:
put your meter on continuity and the neg lead on the c connection and the pos on the nc and the buzzer should sound. Then get mach to switch the spindle on and the connection will be broke and the buzzer will go off. With the spindle off move the pos lead to the no connection and the buzzer will be off, then activate the spindle and the buzzer should sound.
If you've not yet got an extra relay, how are you connected the v3 relay?
Are you connecting it so the spindle only works in one direction (i.e. only applying power to one side of the contactor) when active, or as a changeover so there's always power to one of the contactor coils?
If you're going for the one direction, then you need to assign the Relay output # to whatever pin you have the v3 dir terminal connected to, then set the dir pin in Motor Outputs to something that's not being used.
If you're going for the permanent live option, then you'll need to disable the spindle relays, and set Spindle dir to whatever pin you have the v3 dir terminal connected to. Then to activate the relay for testing, either tell mach to start the spindle in reverse, or tick Dir Low Active for the spindle and start it forward.
For now, i just want it going in reverse..Quote:

the DIR on spindle V3 board is on pin 8, so i need to set the Spindle Dir pin to 8? and for the motor output it needs to be something like 14 (not being used/connected)Quote:

In that case, you need to set the relay output # to pin 8, and set the Spindle Dir pin to something that's not being used.Quote:

You can't use the Spindle direction pin to switch the power on/off, as Mach keeps 'dir' pins at their last set state, until that axis changes direction again. I.e. if you set it so Dir goes active when forward is selected, it will remain active, until you issue a reverse command.
Hi all,
Sorry to interject but I have a question about the mechanics of the Boxford TCL 125. I am sure somebody here must be able to answer it and it would let me get on with my conversion if I did get an answer. I posted the question at http://www.mycncuk.com/forums/showth...screw-bearings
Thanks in advance for any input

So an update...
Couldnt be bothered using Computer command to turn the spindle as it wasnt going as i wanted.. so i put it back on the manual switches on the front! works a treat! i have also kept the 0-10v for speed control on a pot..
Gonna tidy up a few things on the machine then its gonna be up for sale, as im in dire need of a Mill!
Stu
All wiring tidied, everything working fine.
Will post pictures later
P.s.
Now for sale in classifieds (or swap for mill/router)
