I really hope the Invention contest makes a comeback.Also, are there any plans to do another 3D printing contest?
I used the demo version of Mach3, which is free. The demo version has a 50 line g-code limit, which was enough to make some drawings.The best free CNC software is emc2 on linux.
Can't wait to try this out for halloween! The eyes look really cool.
If that were the case, then the third axis would have to move the other two. lm not sure if the axis could move all that weight.
Attached is one example of a CD drive data sheet. I assume that the first 10 pins control the linear slide. Different CD drives might have different data sheets, so I recommend searching for the specific datasheet for your CD drive.img source: http://akashkumar4u.blogspot.ca/2013/05/cddvd-motor-driver-hack-to-run-its-own.html
But the motor that drives the sled is a stepper. Surely there has to be a stepper driver on the cd's board then.
Whenever i took the sled out of the CD drive, I always ended up damaging the pcb. I couldn't successfully remove both the pcb and sled from the cd drive.I would be interested to see if this project can be done with cd drive boards. I'm not sure if a CD drive board can be manipulated in the same way as the floppy drive board though.
Thanks for the tip!
What's wrong with your Mach3 calibration?

Sorry about that. Dunno what happened to the code. I uploaded it again.
