Title: Hi, Where can i get the wiring diagram to the board of a CNC 3040?
Post by: SirFinland on March 22, 2014, 07:57:20 AM

Hi,

I know this is the wrong place but I have to try...

Where can i get the wiring diagram to the board of a CNC 3040?

One compounent is dead...


Thanks!

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

There may be slight differences but I hope this helps.

Hi,

It didn't work.. I was spinning about 2min and 2000rpm and then it burns again.

thanx

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!!

I think the first thing you should do is check your GCode ;
Is your machine / Mach3 doing exactly what the GCode is telling it to do ?
If this is true then it is likely that your CAD/CAM software settings need changing.

Perhaps post your GCode file, then it can be checked here.

Hi,

I put my file here. When I start the mach3 I put the wood on to the cnc and the blade to the wood surface and then zero all the X Y Z axises and then start.. But then it will drill strait in to the wood about 8MM

Thanks man!!

GCode looks OK and it runs just fine here.

However, the first Z move is a G00 rapid up by 25.4mm – if your Z axis velocity / acceleration settings are set too high then the Z axis may be stalling / loosing steps during this move and then have lost correct position.
Try halving (reduce by 50%) your Z axis velocity and acceleration settings in motor tuning and then see if this makes a difference.

Hi,

Thanks for the help it helpt me! But now i have a Little problem...

Do you know what to do? The cnc3040 board is okay, and one day I was engraving and after 10 min when it was done so the spindle didn't stop, it keep runnig no difference if the spindle was on or off and the Emergency stop didn't work. So now when I put the Power on so the spindle is Always on and I can't change the speed on it.

What could be wrong?

Thanks!!

I would suspect that the IFR630 (or one of it’s control components) has become short circuit.

Please forgive me, I don't mean any disrespect, but better quality electronics may be the way forward.

Hi,

Yes I Would want to make it all better but when I don't have the wiring diagram for all the boards :( ( Just the on you gave me)

Wich part is it that is broken if it is? so i could get a better on...

And The YOC PW 3024 I made it better ;)

Thanks

I would check these components (circled red).

Hi,

Thanks....It Was okay for 2 weeks.... What kind of a better board can i look at on Ebay? Name? Sort? So i could get one that works 1-5 years... Not weeks...

Thanks!

Hi Finland,

I can't recommend anyone in particular but I think you should buy from those that offer support for their products and have a known track record.
Perhaps someone like CNC4PC http://www.cnc4pc.com/Store/osc/index.php may have a suitable product.
