PICStep clone with Eagle files

[PsyKotyk]

Just a final follow up. I tried using some different crystals I found at the local Computer Recyclers (2 for $3 yay!), and things started working perfectly. I must have been using some non-parallel cut x-tals. These ones were in the tall can instead of the short one.

The resistor in series with OSC2 can be ommitted completely, so either jumper it, or edit the schematic/layout, or just cover the gap with a sharpie if using toner x-fer.

I had a successful test at 52V (the stepper was certainly moving quickly), but when I touched the heatsink to check the temperature, I felt a definite surge of voltage. I thought the heatsink was supposed to be GND?

Anyone tried liquid cooling for their heatsinks?

when i get my HF mill up and running i was gonna run some copper waterblocks to get it setup and to help w/ cooling.
but i keep smoking my xylotex board, so i gotta get some diffrent motors to try.

I thought I would share a couple pictures of My PICStep Controller.

I am a fan of pcb milling and cut one of PsyKotyk's boards except I put the 5V reg back on the board as my system needs it there.

I am running a tripple stack NEMA 23 stepper at 2.8A so need the big heatsink.

Thanks Alan for the code to make this run.

Here is my version of Alan's board Have a working board. Works great.

I am salvaging 20mhz crystals off of old 10meg ISA network cards. so far I have not had any that did not work.

Hi all. I have all the components to build 3-4 boards for my new CNC machine. Would anyone be willing to knock out the PCB's for me? I am happy to pay for them, and I know that I can buy the PicStep boards (probably the same price or cheaper) but I would rather work with Open Source works. The project looks great, I hope I can be part of it.

Which version? I'd be willing to as I've finally got my pcb cycle pretty well tuned. Plus I could add the code to my website.

PMINMO,

Thanks so much. I would like to use PsyKotyk's latest board revision. Using a external 5V regulated powersupply is not a probelm for my setup. You can contact me directly at jc (at) xephius (dot) com. I look forward to working with you.

Hi,

I just got my CNC router finished as of Sunday night and I'm already looking at modifications, such as new driver boards. I was looking at your set of gcode files. Could you elaborate a little on how you would go about setting up a board for routing, registration points, which NC files to use and in which order. Size of router bits and drill sizes etc. Hopefully, with a little bit of explaination and if I look at things long enough then it will begin to make sense.
