Explain this picture please

[HereinCS]

I'm curious about this picture. The DIN plug I assume is for the motor, the parallel to the computer, is that a vga plug? What are the serial ports for?

What are the three power sockets for? hopefully they are not sourcing voltage?

The heart of this controller is a Gecko 540. The serial ports are the stepper motor power connection points. The parallel (25 pin) is the interface to the computer. I couldn't tell you what the VGA port would be for aside from digital inputs like limit switches and such. The power cable sockets are most likely relay switched 110V outlets for coolant, vacuum or spindle power to be controlled by the computer. At least that;s my guess.

built on the 4 axis G450

25PIN goes to the computer

The 4 other connectors goto the motors

Power sockets May just be extra power for something, Router maybe?

If they are power outputs they are the wrong type and dangerous, Power source should always be female sockets.

Good catch Al. That's insane. A closer look at the internals makes it looks like these are hardwired in parallel with the line voltage. Grabbing that the wrong way would certainly wake you up.

If that is a commercially sold product it won't get a UL or CSA sticker for sure!

The outlets (or some of them at least) are probably relay controlled from the G540. I've seen that box for sale somewhere. If the original poster would post a link, someone could probably interpret the specs more easily.

What's not to love?? Dangerous exposed voltages with no labels... Perfect!

Yours for only $600 at Kelinginc... I can't find any info that says what the sockets are for however....

At least there's a disclaimer:


** You agree that
we are not liable
for any personal
injury or
damage to your
property in
connection with
the controller to
your units !!!! **

The above is the wiring diagram for the g540. 50vdc is the max voltage to the X Y&Z axis. You'll get bit harder from a 2 wire telephone line (60vdc) at the same amperage.

I agree that the ABS controller box is a bad idea. I would prefer an Aluminum cover on a steel chassis with at least 2 fans to maintain the internal temperature under 50c when running. I've also grounded it to the foundation. The back cover on the Grizzly G0463 is big enough to house everything including the PS. I'm working on exactly that. I'll have pictures later. Maybe

I'll grant you that Kelings documentation is crap at best but at least they try. If you have a litigious nature, you have no business doing business with China. There is a reason they put that disclaimer on the website. The entitlement mentality in the USA is what has killed innovation, experimentation and economic growth. That's why we don't make much of anything new in this country anymore.

The issue is not the G540 connectors - it's the power line connectors which would have 120VAC on them.

[Al_The_Man]

Its not the Chinese that have to be worried, it is the importer and distributer here that will be liable, personally I would be a little nervous distributing electrical equipment in the US without UL/CSA sticker, especially when it is used mainly in a non-industrial, domestic environment.
That disclaimer is not worth the 'paper' it is written on. IMO.
