Q: Start Kress 1050 with Gecko540?

[Trulsen]

That sounds pretty good! :D

Could one of you help me and link to needed parts from ebay?

I have this combo: 3 Axis Electronics Kit | CNCRouterParts, so my power supply is 48V. I do not need to control speed of my spindle. At least not for now :-) Want to keep it simple, but it is very nice to start/stop from Mach3 :)

This would be what you want. IACS 2 Channel Relay Board 2CH 10A 3V 5V 9V 12V 24V 36V 48V Finder HUIKE SPDT | eBay

This will give you 2x 10A relays so you could use either output 1 to switch both channels at same time, say for instance switching vacuum on at same time. . . . OR . . . Have 1 output on each channel and individually control each relay. This instance would be used say for turning on a coolant pump before or after the spindle.

If you buy the 48V supply voltage then you can run it from the PSU which powers the Gecko.

The other option is to just buy individual 48Vdc 10A relays for about £5 each but the above option is much neater IMO.

Lots of cheaper ones available, e.g:

2-Channel Relay Module Optocoupler Expansion Board Single-chip Control #T1K | eBay

But as Jazz said, as the gecko can source 1A on the outputs you could connect a relay directly and save a negligible amount of money over the above one!

Edit: Here's some cheap 48V relays:

Lots of ways to do it...

Bloody hell how do they make that and deliver it for £1.62.!!! . . . Unbelievable.!!!

Just noticed thou it's 12V and to eliminate another PSU 48V is best.!! . . . I know before you say it Jon he could still buy 12V supply for less than one I posted but my option is much neater and was just a quick search on Ebay to give the guy an idea.

Thank you guys :-)

How should I then wire my Kress? I guess only the ON/OFF switch shall be connected to the relay and two cables from the Gecko to switch the relay On or Off?

First the Gecko G540 manual shows how to wire it's outputs to Relay coils. Then all you do is break either the Live and Neutral or just one of them depending if your Relay has 1 or 2 poles of the power cable to Kress.
