thanks jazz will try this tomorrow not a fan of the play station control but thats what it came with
thanks Geoff

You don't have to use the PS controller it's just another method of operating the machine for jogging etc, rather than using the keyboard. It could be disconnected and just use the keyboard to jog etc.

morning Jazz hope you are well
i disabled the ps controller with no change
next i bypassed the es now i can move the machine but the homing switch normally light up when i tried to home they are not working i ran a simple prog it ran ok put spindle will not run even tried mdi
thanks Geoff

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



Edit: Opp's didn't see Clive beat me to it, same as what he said...Lol

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:
