Back to Where it Began 06/02/2010
We have not reached the point where this all started. November 3rd of 2008 I posted a video of the HobbyCNC pro board I built driving a stepper motor I found on ebay. It was the first check marks I got to put on the wall of my CNC list. Here is that video for reference.
The next day I fried the board and that was that. I took several months of trying to figure out what I was doing. What went wrong. Where to go from there. I eventually decided to start on the table since I couldnt destroy it so fast. Now, almost two years later I present you with the latest in Steve-O tech. Straight out of the hot plate, with the solder still solidifying (not really), a single RepRap stepper driver v2.3 driving that same stepper motor.
Here is the inside scoop on my choice of the RepRap driver board. Stepper motors are pretty high dollar. As they should be. the driver boards for them are high dollar as well. When I killed the HobbyCNC board it was going to be close to a hundred dollars to replace it. No way to fix it. Now schematics. Nothing. I figured it shouldnt be that way. So I set out in search for a replacement that was open source to I could test, repair, or modify the circuit. It also needed to be strong enough to handle the motors I currently had. The RepRap design turned out to fit the bill and I went with that. Ed over at EdsLifeDaily seems to have found a similar solution. with that said, there are tons of solutions out there for this same problem. Even more if you know how to design your own circuits. Feel free to contact me if you have any questions, need some direction, or just plain want to share your project with me.
So whats next? Well I still have to finish the table. It still needs a drive system. I also need to come up with a way to get drawings to g-code and then to the arduino. I may have stated it in the past but a friend of mine has volunteered to help out with finishing this up and no0w that I have a working stepper drive we can move on to the next check mark.
