A photo of the inside of the controller box and a photo of the dead component would help identify which board you have.

Check D4, R3 and R4 are OK also check solder joints D4 – R3/R4 – IFR630.

Hi,

The wiring diagram said that it is a 100 ohm resistor but it burnt right away...

Did I something wrong or was it the diagram for this board?

Thanks!

There are many possibilities ;

If either R3 or R4 had expired then too much current would flow in the opto isolator circuit. Likewise if the capacitor C9 was faulty there would be similar consequences. There is always the possibility that the opto isolator EL817 is at fault but then – that’s the joy’s of fault-finding. :)

Hi,

It works now but when I'm trying to do something with the cnc so it will drill straight down about 8mm, but i should only go about 3-4 mm..
But after the first 8mm then it will do the 3-4 mm as it should do.

Why so?

Is it the Board or some settings?

Thanks!!
