HobbyCNC driver board assembly

Electronics are progressing along and I gather some good footage for the instructional video that will accompany this build (albeit most likely following the build or at least lagging the progress here).

Nothing too alarming here other that if you open up the ‘kit’ for HobbyCNC and see that it truly is a kit… that might be a little alarming. There is a fair amount of soldering involved and so it would be advantageous to have a good soldering iron or station. Component placement is very straight forward. The only suggestion I had for the instructions was to better describe the placement of the three jumper headers. It talked about J1, J2, J3 & J4 but each header block is a set of those four jumpers and there is one block for each of the axis of the kit. Pretty straight forward but could provide a point of confusion.

I didn’t receive my transformer yet so I hooked up a 12VDC power supply temporarily to verify the wiring was correct as stated in the instructions. I measured 5.01V at the test point which is right on the money (acceptable range for the drivers was 5.0 to 5.2).

I’ll start with the preparation of the metal pieces for the gantry next…

LILCNC Project Begins

… and so it begins!  Over the course of the next few weeks I will hopefully complete my build of the open-source DIYLILCNC mill.  I’ve been ordering parts from the suppliers listed in the instructions and have received many of those.  During the course of the build I will be adding videos for each step along the way and with any luck I will have a fairly complete build on video.

A little background on me.  I have a degree in Electrical Engineering but have not been practicing for many years other than in the workshop and backyard.  I own a company that builds custom video conferencing solutions for healthcare as well as produce some media and online content.  I have a DIY’ers workshop with nothing fancy in the lines of tools but have a good selection of them to choose from and so hopefully that will not prove to be too big of a challenge in building this mill.

I want to first and foremost give credits where credit is due.  I’m merely one individual building the very slick and straight forward design by Taylor Hokanson and Chris Reilly.  They really get all the credit for the design and instructions associated with this mill.  The website for the mill is www.diylilcnc.org and I’ve purchased the laser cut parts for the mill directly from them.  But we’ll get into that a bit more later.

I hope this resource will prove to be beneficial for someone out there and will inspire others to take on this project.
