You beat your mid aug date. Great news! Way to go!

Hi,

The G540 is ready and is available for sale starting tomorrow. I have attached the G540 MANUAL.pdf for those who want to look at it.

Mariss

In the manual, it looks like your suggested wiring diagram has two wires switched, pos #6 and #10.

[rgoldner]

Mariss, congratulations on getting the G540 out. It appears that the wiring diagram is wrong in respect to the wiring of the E-stop switch. The text says pin 6 and the diagram shows pin 10.

Actually, I just added the G540 to the website. It is for sale right now for $299 with the manual up on the site as well. Enjoy!

Oh jeez.. You are right. That's what happens when I hurry. I'm correcting right now. Thanks.

OMG! THE 540! Will be buying this week!!!!!

In the manual you suggest using a N.O. switch for E-stop. I always thought that an N.C. switch is safer as a broken or loose wire would cause an E-stop. Using a N.O. switch a broken wire will result in E-stop not being available.

Hi Guys,

Could we just use a Inverting Buffer so we can still use the E-Stop as a normally closed switch?

Just an idea.

YEE HAW!!!!:cheers:

Glad to see your hard work has paid off, Mariss. The only problem I can see is that it will probably be another week before I can afford to get one. Now that it is finally here I will be trying my best to get one as soon as possible though. Can't wait.

Hi Al,

For EStop, you would probably be better of with a small N/C relay using the contacts to close the stop.

Then connect all your estop switches in series so that they activate the relay coil keeping the contacts open.

That way if any switch opens, or the wiring fails the relay will close activating the G540 ESTOP.

BTW, your estop setup should do more than just signal the G540. You should also considered removing the AC power. It all depends on what machine is being controlled and what damage it can do. :-)

Cheers,

Peter.

Hi Peter,

I have designed my E-Stop circuits to deactivate the transformer output before it goes to the diodes by using a relay.

My E-Stops are the standard DPDT type, so I can do it that way. Your suggestion about using a relay makes sense. The inverting Buffer would be useless if power were lost.

Thanks for the heads up,

Al

I am guessing that you actually can wire the Estop in normally closed mode.

The G540 inputs most likely are passive so you just ignore the diagram since its only a suggestion.

Al suggested a buffer however no additional device is needed.

Marris can you confirm this?

Nice to see you are making progress, maybe the $39.00 G251 will ship in a few more days.

Let us know if you need a cake for the celebration.

OK, the pdf has been updated.

Mariss, love the manual...Very simple and straight forward. Look for a purchase from me at the end of the week! Amazing

rgoldner,

A lot of these issues will be addressed in the next revision. We had to get off the dime and get this sucker out there.:-) We are also looking at providing the 4 mating male solder-cup DB9 connectors and metalized plastic backshells (Digikey 109MEA-ND and 909GME-ND respectively) with each G540. That should make motor cable fabrication easier for users.

Mariss

[CROSSHATCH]

Oh for sure! But you provided the part number which is great! Thanks!

There was talk about including "Mach3 closed loop spindle control to work" via PWM to an optocoupler. Are you still looking at including this in the next revision of the G540? I'll wait for that if it is going to be included next time round. Thanks again for a great product and sharing the design process.

any news?

i also have not been following this thread for about a week, where are people ordering their 540's?

edit- right from the d*mn website...


i fail sorry

[jalessi]

Is there a .XML file for the G540 availible for download?
