Hi, thanks all for the information
My Problem, i make a hot melt glue dispensing machine up to now the customer has been happy with using the PC keyboard and mouse but as some expert wants more out of the machineand has concluded that the machine would produce more if the operator only has to press buttons, cant argue the point..
So i think this is what i need to do, bear in mind its a 2 axis glue mache=ine with instead of spindle start, stindle start operates a relay to switch a valve to dispense glue.
Buttons required 4,
Cycle start Port 1, Pin 12, OEM Trig 1 set to1000
Cycle Stop Port 1, Pin 13, OEM Trig 2 set to 1003
Reset  Port 1, Pin 15, OEM Trig 3 set to 1021
E-Stop set up as normal on Port 1, Pin 10.

Can anyone confirm this, that i have the correct codes for the latest lockdown version of mach3.
The buttons are momentary press/release

Thanks to all

Look forward to anyones help, Thanks in advance

Hi, thanks for getting back so quickly.

Following my last post i got into my workshop and checked over my wiring i found 1 x motor shield faulty and not going to ground, also found limit cable not grounded with a break in the shield, very small wires.

Made up new motor shielded cable and fitted it.
Next soldered a piece of wire to the faulty limit shield and run it to ground.

Have run a few programes to try, all worked ok so i will tidy up the wiring when i`m at it next and retry the router. Monday i should think.

Will be away at our holiday getaway in Mid Wales on the coast for a few days to check the place out following the extremely wet and windy winter in the UK, wetest on record.

Thanks for your help, very much appreciated.
Best wishes

Hi, i have tested the EStop switch circuit and it is working ok as NC with the limits switched off in Mach. Have run a test program and the router runs ok.

Activated the limits and result as below.

So i have just run a short program and it stops with a limit switch activation tried a few times same result without an actual limit actuated.
The limits are wired in series and are NC.
The limit cables are shielded and the shield grounded to the bob.

So i guess its onto another problem

Best wishes.

Hi,
Bob is wired to port 1 and pin 10.
Out from pin 10 to one side of the switch then from the other side of the switch to the ground of the bob. This ground shared with another ground.

The cable is twin core shielded.
I have tried grounding the shield to the steel enclosure through the plug, also grounded it direct to the bob and also grounded it to the earth terminal inside the case all gave same result.

I built the controller from components i picked up in a few places. I have built a controller before, a few years ago exactly the same and it was fine, but i droped out of the cnc thing due to health problems, back fighting fit now so at cnc again. I`m in the UK so its evening now, i`ll try and take a few pics tomorrow
Best wishes.

Hi Again,
My e stop has 2 x sets of contacts, one for NO (green) and one for NC (red),  wiring connected to NC. IT is not making any difference if i untick active low makes no difference Estop request still on.
I am only using the e stop to stop the machine in Mach.
New machine and controller.
Regards Billybob.

Hi, thanks for your reply.
Limits are in series and NC config ticked for active low
E Stop now changed to NC config ticked for active low

On screen E Stop flashing on Message External E Stop Requested
Tried debounce at 1000> 500 no change

Cannot get off E Stop to run the machine.
