This post is a review on my experience with upgrading my standard K40 to an aftermarket Controlboard. I had used a standard K40 for about 5 years until it died one me, and with the newly purchased one having issues, I decided to go aftermarket and not deal with the Chinese “support” I was getting from eBay
After posting on here for help, @Paul_de_Groot was kind enough to offer me one of his test boards (http://awesome.tech/) to see how I went with performing the upgrade myself.
The physical upgrade was very easy, only one extra wire to install (used an old CPU fan cable as it had the right female socket) an Endstop sensor flag and rotating the Endstop sensor. Everything else plugged directly into the board, no fuss!
Connection to PC is via USB (micro – same as Samsung phones) and the software used is Inkscape + extensions within Inkscape (both Raster engraving and cutting) - http://awesome.tech/using-the-gerbil-plugins/.
I mainly use my K40 for engraving woodwork, which I have not been doing much of recently, so have only now just gotten around to really getting stuck into playing with the setup and getting to know the new process and controls.
All in all I can say it has been a very easy process, Paul has been great with helping me out with all my questions (I work in IT but have 0 experience in anything like this, GRBL, GCode and CNC type stuff in general) and although I am still playing around with the fine tuning of settings, can say that the amount of extra control and detail I can get now is amazing! There is plenty of information available for beginners like me at awesome.tech and GitHub (https://github.com/paulusjacobus/grbl/wiki/Configuring-Gerbil-Grbl-v1.1e)
Attached some pics of my most recent tests
Again, massive thanks to @Paul_de_Groot for helping me out, so glad I went this route!
