Re: mach3 wont reset keeps saying external emg stop requested
Ok regards the PS controller that's about what I expected because it's just software driven and your problem is hardwired. So, unfortunately, you are going to have to do a bit of detective work and start tracing wires.
Now because the Home SW doesn't work and Spindle won't start I'm thinking your problem could be the BOB(breakout board) and it's I/O (input/outputs).
Looking at the pictures I'm pretty sure this breakout board needs a separate voltage source for the I/O to work. The pictures also show 2 PSU, the smaller one will be the low voltage for this and the relays, etc, the large one for the drives. So first check you are getting power out of the smaller PSU, it's probably 12 or 24Vdc.
and that it's getting to the breakout board.
To be honest I'm quite confident your problem lies here with the voltage to the I/O but if you are getting voltage to the BOB then I'd 99% say your BOB is dead. But it's always worth tracing wires for damage or loose connections.
After this I can't be much more help without being infront of the machine.
EDIT: The two middle connectors on this block is were you need to test for voltage. 3rd from end near USB is Gnd and 4th is Vcc.

hi Jazz
is the BOB, in my second picture the board in the middle i noticed today there is a red led lit up
sorry but what is PSU i have a multimeter so i can check voltages

PSU = power supply. Also check if you have 5V as it seems you have a usb providing that and some usb's don't supply enough current.
As Jazz says you need to supply the bob with two sources on power ie 5V and another somewhere about 12-24V where Jazz indicated on the picture
Edit: do you actually have a 5v power supply in there because if you do you don't need the USB cable connected

Yes Geoff, PSU = power supply unit. It will be the small one in this picture and test the V++ V-- highlighted in pic. The PSU will probably have sticker telling you the voltage Output. 12 or 24Vdc

I have the same board matey.
Do you have a 12v-24v supply in there?
These boards limits, probe, spindle and e stop are supplied seperately on these to keep the inputs isolated on the 5v.
You need a 12v-24v to supply all of the above.
It's on the right in the picture:

Re: mach3 wont reset keeps saying external emg stop requested
morning all
on the two psu s there is a green led on the larger unit it is lit up on the smaller unit it is not, does this mean the unit is dead ?
thanks Geoff

Geoff. Do you have a DVM ? a meter to test the voltage AC and DC . If so can you check what voltage you are getting from each PSU on the DC terminals.
The smaller PSU should be putting out about 12-24V if it is not doing so then you need to check if it is getting 230V AC on the input. There may be a loose connection or a fuse blown.

hi Clive
yes i have dvm i assume L N are 240 volt but how do i check the v- v+ do i put the black probe on v- and red on v+ sorry im not up on electronics
thanks Geoff

Ok, then you have found the source of your problem. If the small PSU as a fuse checks this, also check wires are not loose(do this with power off). If not fuse or wires then it's dead.
To replace you will need to find what power output it was giving you. The BOB will take between 12-24Vdc but it could also have been powering things like relays so it's important to know the output and replace with the same size. Looking at the relays in the box I'd guess it's 12Vdc because they look like Automotive relays which will be 12Vdc.
