Need Help!- MPC03 Problem / Patchboard P68

[fliegeregge]

Hi all,

i am working with a CX-1260 Laser machine 80W and LAsercut 5.0 with
MPC03 Card.

It worked very well since 3 years. Some Tube changing, some software crashes... the small things , ya know...

But today - PROBLEMS - !!

The motors didnt work anymore !

Checklist:

Driver/Software/Dog - OK
MPC03 Card: The green LED No. 4 is on, if I move the head with the software the LEDs go on as they should. Card semms ok and no errors in software (driver).
But the head didnt move !

Then i checked the P68 Patchboard inside the machine. ALL LEDs are off !
I try to move the head over the control board - nothing happens.
No movement, no LEDs.
5V ok.

Now checking the power supply if there is mistake.


ANY IDEA ???? Please Help.

Hi again,

maybe someone is familiar with that kind of trouble.

First the things that are checked and ok.

-Cant move the head by hand. The motors are "on break" and OK. I have to switch off the machine then they are free. OK.

-LED D1,D2,D3,D4 on PCI Card MPC03 are on/off as they should be when moving X/Y axis in the software.

-Laser can be fired with the Test-Button.

-No error message from software - Software/Card Driver ok.

-Green Lights and voltage on the drivers (the black boxes).

-Chip 26LS31 changed twice on the MPC03 Board. All ok.


Now the bad stuff.

-The Motors (X-, and Y-axis) dont move.

-All lights on the P68-LV Breakout-Board are OFF.

-I can NOT move the head. Wether by pushing the buttons on machine nor by software.



More information for troubleshooting.

If i push a move-button on the machine the corresponding wires on the left side of the P68-LV Board says 4.88V.

But nothing happens with the motors.

The Power-LED and ALL axis lamps on the P68 are OFF.

The Multimeter says 4.88V between pin 1 and 2 on the P68-LV board.

The fan of the big main power-supply is working.

There is another big "High-Voltage" Device above the P68. It show a green LED and its fan is also working.

There is a smaller "High-Voltage" Device with lots of holes in the cover. The green LED inside is OFF.

Any Idea ????? Urgent ! Winter is coming !!

Many thanks !

I think you need to replace P68-LV
