Hi everyone! In this part I'll finish the assembling of the homemade CNC machine. Subscribe to the channel and put your thumbs up! Enjoy the watching! 3D models for NC machine:www.thingivers... / goryashchiyeklyuchi
thanks for showing this low tech approach but this still wastes resources, you also can 3d print or mill wax molds to make uhpgc concrete parts with unidirectional fiber reinforcement and place it in the floor instead making a table, and also you can make a concrete mold to make rack and pinion with fiber reinforced recycled PET plastic
For those machines I always have the question how the SW works. Which program do you use, do you write it on your own (which would be quite hard i assume)? Do you use a raspberry pi or is it some kind of PLC (because you are obviously have a PC attached)? Would be amazing to get an insight of how the software can work or is working in this project...
I saw that they were using Mach3 to control it. The controller board is premade and comes with drivers for Mach3. They're pretty cheap but often require a parallel port. Software goes: CAD -> CAM -> Mach3. CAD to design the parts, CAM to create the toolpaths and turn them into gcode, and Mach3 to read the gcode and send it to the router. CAD and CAM could be done in something like Fusion 360 on a separate pc, so this computer is just here to run Mach3.
The best thing to use is an arduino and download grbl on to it, use easel software to control it I’ve built a few and it’s easy doing it that way, if u need any help let me know and I will send you my number and I will help through the whole thing
Some clever ideas! I like the trusses. I will use this design on my gantry cross-member. Square tubing on a diagonal as the main-rails for bearings? I dont know, its their weakest orientation. Also as the gantry travels to the middle of the span, the rails are going to sag. This is why professional units support the bearing rails along the table edges (which you have provided with STRONG truss frames, then didnt use them to support the most critical and largest load. Sometimes its best to bounce your ideas off of a willing friend before building (or showing) an idea.
