I was expecting to make changes to this device but I wasn't expecting it to happen so soon. I've now made 3 of these devices at peoples requests. I was thinking about how it connects in to the leetro controller and I realised if I connected to the original controller I could duplicate the signals coming from that too. This would allow me to adjust the Z controls using the PAD03 panel the same as before. I can also draw power from the leetro controller so even if the device isn't connected to the PC the whole thing still works.

Lasercut 5.3 has a bit of a slack way of dealing with the z control, you nudge it up and down a bit until it's in the right place according to the height tool. The amount depends on how long you hold the button for. One of our customers wanted to be a bit more specific about how much the Z axis moves, that way they could make 5 passes on their material and drop the Z axis by 1mm each time. So I made them a custom Z axis controller, this one connects to the PC and allows you to send specific mm commands to the Laser cutter. The PC end is a simple interface that allows you to send 0.1, 1 and 10mm commands to the controller, but it also allows you to send a custom distance. (software bundle here)
The PC controller actually detects when the USB serial port of the Arduino is attached and removed and it opens and closes the serial port appropriately, this means you can leave the program open all the time. The laser cutter, softdog dongle and Z controller could also all be attached to the same USB hub so you only need 1 wire running to the laptop while cutting.

After Donkey Kong, Pacman and Lunar Lander we were having a discussion about which other games could be turned in physical versions. So about 6 months ago an idea was forming in my head, more recently I've managed to get all the pieces into the right place to make it happen and my physical version of space invaders was born.
I've document the whole project over on the sharks blog because I've used a Whitetooth laser cutter, a rotary attachment and a break in board.
So you can check out the whole project here
