So...who's got an extra can of chip smoke?

[millerized]

Let the smoke out of the cheapie 5 axis board. Who's got a can of replacement smoke near me?

Somehow I forgot I made the Z-- limit connector in my cabinet have something to do with 110V and a relay. When I hooked in the pair of limit switches to check operation...the smoke port popped and all the smoke and orange light came out.

Just got the bloody thing working this morning...even after the 60V power supply started putting out 30V last night and I had to order another one. Fine, I'll check them with the 36Volt PS... This morning, after a few minutes of final wiring, I got the motors to turn and finalized the ports config. Soon as I started checking the final parts before I started building the table....the smoke came out.

Ordered 4 replacements off eBay, should be in next week. Sigh...I wish I kept that case of canned smoke.
Guess I'll keep that door closed for a few days...just in case the smoke wants to put itself back where it came from.

So, you have a beautiful control box, everything mounted and wired beautifully... and a cheapo 5 axis board?!

It's what I started out with.
Just built the rest of the box around it.
There's room right up next to the VFD for the 'real' one.
(tax return is here Wednesday, not sure which direction the MC will go...either ethernet or USB, but not cheapie 5 axis. They're destined for another project)
$1200 worth of steel will be ordered as well...lots to do before the controller gets mounted.

Took out a few traces under the terminal strips.
Probably solder in a few wires and it'd be like new...
$20 anyone? :-)

at least it looks like the board was opto-isolated.

i just ran out of canned smoke, after testing an old computer PSU (it wasn't a good one...)

Scary part, is it was still controlling a few items after it smoked. I could still toggle the spindle on/off and move 1 of the 3 axis. Pretty solid board in that regard.

imagine if it wasn't opto-isolated!

when i get things built/bought and so on, i was thinking of building my own breakout board. (electronics is my major hobby) nothing too special, but clearly i will want opto-isolation (was going to anyway).

I like your setup, with even the computer built into the control box. looks clean and tidy.
