General Mach Discussion / Power Supply upgrade 24-48 G540 the Bad Pins?

« on: November 06, 2009, 10:32:50 PM »

Ok this maybe my bad feel to abuse me if you think I need it.  

Last week upgrade my power supply on the Router from a 24v Power supply from the old xylotex kit to a 48V 8.3A Switching Power Supply.

All I did was change the wiring over from one power supply to the new 48v PS.

What happened was my limits and Z-plate were set off so disable them didn't have the time to stuff around I then pushed up the kernal speed and had a play with them and checked to see what speeds I could get with the new power supply was a very happy little chappy with that side of things.

So today I get back into fault finding mode enable the pins on the Limits etc and the Diag screen limits are lit up......
I changed back to the old power supply still pin 10 and 13 no go nothing Diag screen limits are lit up press limits and nothing at all.

I then changed my limits over to pin 11 and it works fine back to 10 and yep cant be seen.
Did the same for pin 12 all good on that one
Then 13 that I had my Z plate on  it was dead as well.

So what would have caused this?

I thought the G540 was set up to handle a 48v PS or have I just blown the pins on the computer why did this happen have I missed something in the G540 manual?

I am not going to hook up the limits etc to the other pins unill I work out what the problem is.

Any help would be appreciated so can get to the bottom of this.

Thanks Willy

General Mach Discussion / G540 and VFD SPindle

« on: July 02, 2009, 11:32:45 PM »

Gday people.

Has anyone hooked up their G540 to a VFD, I have wired it up as per Mariss directions but am a little lost after that what I need to do.

Try:

VS to G540 VFD + supply.
VC to G540 VFD out
GND to G540 VFD ground.

Mariss

Anyway what do I do from this point on in Mach I have done a fair amount of searching cant find much besides my own posts via google  .
I have gone through the videos but just getting more confused and am hoping someone else has hooked one up or can point me in the right direction.

Thanks Willy

General Mach Discussion / Xylotex and C11 Issue

« on: February 19, 2009, 05:11:16 PM »

Hi Guys,

I am having a bit of an issue with false triggers I have set up my C11 rev 5.4 and xylotex. I have added four limit switches separate on four of the pins 10,11,12,13 all normally closed (powered up switch turns them off) they all work fine I can see them in Mach diagnostic screen on and off no problems no false triggers all good.

I then added the connected xylotex ribbon from the c11 back to the xylotex and powered up and I get a false trigger on pin 13 after a period of time I changed Debounce to 2000 still the same thing and I can also see it triggering on the Diag screen in mach.

So I thought maybe a faulty switch so I wired the pin jumpered 13 to the 5v and it still triggered and you can see in in Mach3 Diag screen, maybe pin 13 is faulty so I change to pin 15 I still get limit triggers as well but I cant see them on the Mach Diag screen.

So I am a little puzzled 

I don't think its noise as if I power up both the C11 and the Xylotex and don't connect both boards with the ribbon cable I don't get any Limit triggers.
When I do connect the C11 and the Xylotex via the ribbon cable I then get triggers.

all I can think of is that the Xylotex board is sending back a false trigger through its own pins thus the C11 is sending the signal on as it should thus causing the trigger.

I don't quite understand what could be causing it besides the Xylotex doing it but then I am probably wrong lol, can I disable the pins on the Xylotex board?

I will also add my XML file just in case I have done something wrong.
