Re: My pursuit of the perfect Electronics Enclosure

And I was told the 3D PDFs weren't working for quite a few people, so, here's pretty pictures... My biggest problem with some of this is mounting the main control board (the big blue one) - It is a Chinese 5 axis CNC controller, that only has the 4 mounting holes on the board. the heaviest component...

My pursuit of the perfect Electronics Enclosure

So I was daydreaming, and got a handful of connectors and misc electronics parts from work, which made me think I needed something to put them in. So I jumped the shark and decided to design the perfect "industrial" Shapeoko control package with the electronics that I pretty much already have. I am ...

Re: -VDC, GND and 0V...ack!

Looks good now. Minor suggestion: I'd put the spindle switch on the input of the SuperPID. Generally speaking, triacs and other solid-state switches don't like to have their load connected and disconnected while under power -- so no switches on the output circuits. That was going to be one of my ne...

Re: Candle Molding?

What type of candles? Columns, no problem. But anything more intricate you could always mill a positive and then make a Silicon or Resin mold to pour into. She wants to do large chess pieces and such. I was planning on molding the halves - do a positive in SolidWorks, toss it into a cube, and subtr...

Re: -VDC, GND and 0V...ack!

Ah! Ok.

My latest diagram as posted above should be correct then.

It doesn't show the DC relay connection side as I will be using a Teensy++2.0 for the PC interface for my control panel and for those two relays.

Re: -VDC, GND and 0V...ack!

I haven't checked the AC part of your diagram, but the DC part is a bit wrong. On the power supply, V+ and V- are the terminals between which is supplies 24 V. They're not labelled 0V and +24V, or GND and V+, because they're floating. Neither V+ nor V- is connected to the frame of the supply (and t...

-VDC, GND and 0V...ack!

I attached my power interconnect diagram I worked up today. CNC Electronics Interconnect Diagram.19FEB13.pdf I am trying to figure out if it is safe to tie the VDC GND, and VDC 0V to the AC GND by adding a few more blocks to the terminal strip, versus stacking all the grounds/0V to the power supply ...

Re: Ideas for enclosure chassis...

So, because I wanted something clean with a full control panel, I've jumped the shark a little bit and decided to go with a rackmount solution. Going with a 12U rack, with four major components - 4U PC Rackmount (going to take it out of the midtower case and move it over - its an older PC and is per...
