It's a PIC microprocessor based circuit designed as an addition to an existing industrial controller to slightly modify the program sequence and timing.

I had not tried this before, OK it's a very simple circuit but it still needed a circuit board.
Isolation routing is simple, easy and is just like engraving I don't know why I didn't try it sooner - it sure beats ferric chloride for simple one off jobs.

I did not use a dedicated PCB program, instead I created the layout as a bitmap then outlined it as a vector image, exported it as an HPGL plot file then converted it to GCode. Quite easy really.

Well done Ed.

CNC Cookbook changes it's pages regularly and it's links change. I had been unable to find the cube making link as well.

SmoothStepper USB / Re: Smoothstepper disconnect safety concerns

I just can't resist putting my spoke in again on this thread.

No matter how unlikely, sudden and unexpected, power outages will and do occur at the most inappropriate moments. The design of all machines must be able to handle a sudden power disconnection in a controlled and safe manner. The ultimate and effective emergency stop will disconnect all power to the machine instantly. In other words - if for some unlikely reason the software polled e-stop has no effect on a runaway machine then pull the power.

No problem guys, I am thoroughly enjoying the information sharing. Keep it up.

Cubes rule !

Nice set-up Vince.

It seems that your wife is a lot more understanding than mine.

Yup ! - it's all Marcel's fault. I have bad dreams about cubes. I just want to get back to the wood routing.

SmoothStepper USB / Re: SS DISCONNECT SAFETY CONCERNS

« on: January 19, 2009, 12:33:36 PM »

I am in full agreement with Jeff here. I have had the SS for some time and it is an excellent product. OK I use the E-Stop function but my real Emergency Stop disconnects power to all functions of the machine instantly. SS has not killed a man as the thread title states (in the event that I am wrong then prove it !).

Brilliant work (well produced video as well).
