Rhynier,

I purchased the same Wantai kit that you seem to have. I really like it (nice packaged drivers) minus the lack of documentation and support. I seem to be having heat issues with my motors/drivers as during a longer running job, the motors and drivers are very hot to the touch and the different depth passes begin to shift.

What power settings are you using with your drivers, and have you had any issues like this?

Not exactly a stepper driver, but this may be a new option since it's getting harder to find computers with parallel ports: Using a Beaglebone Black as an embedded controller.

Bart has a good writeup of the board and his adapter: http://www.buildlog.net/blog/2013/09/cn ... eaglebone/

I ordered a Beaglebone from http://www.adafruit.com/products/703 and a parallel port breakout from http://www.ebay.ca/itm/DB25-Parallel-Po ... 183&_uhb=1 to do a breadboard setup. I'm going to try getting my Shapeoko running with it, connected to one of the eBay TB6560 boards. Total cost will be under $200 for everything if it works out.

I was also reading about connecting a tablet with USB to control the beaglebone through ssh. I have a Google Nexus 7.

Be sure to post how it works. It looks to have a lot of promise. Much more so than the RaspPI. Has a lot more IO too. Its pretty easy to run up against the limits of the parallel port.

Why do you need USB on the tablet?

From what I read, you can control the Beaglebone over USB or a network connection via ssh. I was planning to use USB to make it a standalone system, no wifi required.

Ok. But if you use WiFi, its wireless. :)

Its using HippoRemote on iOS to create a custom keyboard that connects to the LinuxCNC machine via VNC. There should be a similar app for Android. Its a pretty neat setup.

That is awesome. I have a wifi dongle from my raspberry pi, might give that a shot.
