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

« on: November 09, 2009, 05:02:09 AM »

Ok Cool what pin is ground ?

I am running at the moment all good but still would like to get to the bottom of this.
Can the optos be easily replace on the G540 probably should go and ask on the Gecko forum but before I do that I thought I would just ask 

Thanks Willy

All limits are in series NO I think switch stops the ground signal getting through always have problems with remembering the NO NC thing lol.

I tried that little Progy four top left were all all red the rest green does that mean the parallel ports fine?

When I set off the limit I get nothing on the original pin on the new one it goes green  

How do you have your limits/etc wired? You should have them wired between Pins 1-4 (inputs) and Pin 12 (DC Common) on the G540. You do not apply any voltage, i.e. 24/48V, to these pins. It sounds like you may have messed up a few of the opto-isolators on the inputs (better than your PC though.) Give Gecko a call, they can repair it for you and they are very generous.

Yep that's how I set it up the only wires I changed were the moved were the wires from + and ground.
I just changed the limits to the next position (2) thinking that if it dies well cant lose anything really I just have to be careful.
But the limits work on this position, I am a bit puzzled why this would happen?

I am all the way over in Aussie land so to get it back to Gecko is a pain and I have jobs lined up for the router cant afford the down time at the moment.

Any other thoughts guys why this would happen?

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

Hi Timothy,

Thanks for that gave it a shot but I am still getting nothing will walk away from it for a couple of days and try again I think I am missing something not sure what though maybe some settings on the VFD that I have missed.


Bloody aggravated that's for sure

Hi Timothy,

I have a Manual if that helps page 19 shows the Analogue as well as other inputs its a Sunfar C300 VFD (chinese VFD  )
I hope you can make some sense of it I am going to have another play in the morning when I get a chance.

Thanks Sean

Hi Timothy thanks for the reply I was getting worried that no one has done this so far.

Are you just talking about turning the VFD on and off straight from the G540 0utput or using an external relay?

I am also lost on the Mach set-up should I be using PWM or Step.
If you have the time can you explain how you have it set up I have lost direction and confused myself to a standpoint  .

Thanks for trying to help

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

here's a more lengthy WMV of the changer in action:

Hey bloy,

Can you tell me what speed your running your router at I was looking at this system but when I sent them an email Fred no more then 10k RPM do you have any issues with it running at high speeds I have a spindle capable of doing 24k and would love to have an ATC set up.

Thanks Willy

General Mach Discussion / Re: Xylotex and C11 Issue

I think single ended shielding of all signal and stepper cables is the key - at least, it worked for me.

Woody.

The interesting thing was Woody is that without any wires going to the Bob and just 13 0r 15 pins jumpered to the 5v made out of a small piece of soldering wire and it still sends a signal  disconnect the Xylotex board and it stops no signals at all coming through the Bob.

So to me it looks like the Xylotex is sending the signals no other explanation for it really.

Well a little further and I think I have solved the Limit switch problem I just wired all the switches up in series onto pin 10 on the bob an hour has passed with no problems 

I would think that it would should have worked the way I set it up to start with each switch on its own pin and it doesn't explain those stray signals but hey I guess I still have a number of pins left for something else.
