excellent thermal performance using integrated heat sinksįinally I wanted to design a friendly cable management strategy for the CNC Cube.My goal is to develop a GRBL controller with the following features. I plan on prototyping the various component circuits separately and then when I have everything working I will integrate the designs into a single PCB. Controlling the XYZ axis is relatively easy but designing a 300W spindle speed control will take a bit of work.
#Grbl controller 0.7 code#
I have started to port GRBL () to an LPC1347 ARM processor but the code is not fully functional quite yet. I am also developing electronics to control the machine. I didn’t have any specifications for the spindle so I needed to measure the part to allow me to design the YZ axis I ordered an inexpensive 200W spindle motor to use with the machine and now that the part has arrived I can finalize the Z axis mounting design. My preliminary design results are very encouraging and while there are a few issues I am confident that I can come up with a workable design. The entire machine is designed in Inkscape and is made from 6mm MDF. The mechanical connectors include a threaded T-nuts and using nuts and bolts in a laser cut slot to clamp the frame together. The preliminary work consists of defining a cutting pattern for tongue and groove joints that provide a tight friction fit along with a set of mechanical connectors that I could use as part of the construction. This is also an experiment in making a 3 axis CNC machine using a laser cutter. I decided to make a small PCB milling machine so that I could panellize the PCB boards I design.
