If this is a stepper system, which I suspect that it is given you’re not seeing a “drive fault” on the screen then it sounds like you’ve lost power to your stepper motors.
Open the control box and you’ll see TWO large power supplies side by side (they’re the two biggest components in the box…
If the E stop is NOT pressed, and the machine is NOT in a reset state and they have no power that’s your issue. If they had no power the controller would let you “jog” (numbers would change on screen) but the machine wouldn’t move. You wouldn’t get an error because the controller doesn’t know you don’t have power to the motors.
If this is the case I bet it’s a matter of a loose wire. Again, making sure that the machine is not in a reset state and the E stop isn’t pressed, if those supplies aren’t on go ahead and get in there and wiggle some wires around to see if you can find a loose connection. If you do, you’ll likely get those supplies to light right back up.
Once you’ve identified the loose connection (if that’s it) power everything down and address the loose wire, fire it back up and test.
Just be careful while you’re in there… those main power supplies are fed by line voltage (110/220) and the rest is DC 24/48 volts. It’s safe in there, but just be mindful.
It seems power getting in here but not out….no emergency …if this indeed is a bad part what can I replace it with.? if I order on I ll get in 3weeks so I need a solution to get going.
Ok rechecked that relay is passing power….now the 2MW 480 both are getting power but the dc ok lights are not on…..is there an internal fuse? on those?
I still got my Mach4 power supply I think they are the same.
Ok some update I connected one I had from my Mach4 box and it lights up so it seems both went out at the same time….
now how do I remove the Centroid power supply?
the ones in Mach4 cabinet..there is a small lever below you can pull…breaker style.
What are you guys using for voltage protection?
I have a voltage regulator on it but I am guessing a ups might be better?
if yes which one would you recommend?
Tnx!
update
So I swapped both power supplies and the machine is back up and running
I did not run it yet but It moves and all the drives lights up once the relay is activated.
attached pics…I removed the white box because it seem to lead to nowhere and apparently is it for the brake?
Also from the SP/THC connector I am left with 2 wires orange and black should these be connected to somewhere…I do not remember I took pics but it was not visible.
Glad you got it working.. however I’m not convinced that those power supplies are bad… it takes some pretty extreme circumstances to kill those.
I’d pop them back in the Mach control. If they light up when you power the box then that wasn’t actually your problem.
What I suspect is that you actually had a loose wire that wasn’t closing that contactor and by replacing those power supplies you may have disturbed that wire into a place and that turned them back on…
And yes that small power supply is for the Z brake. I would put that back in in case you ever upgrade to a brake in the future.
