When securing the other side, we must make sure that the two sliding blocks are on the same position on the X axis. I repeated this process for the other side as well.

Therefore, in the STL download files, I also included two versions of the shaft couplers and the mounting brackets to mach these dimensions. Here I’m suggesting to use 5mm because these dimensions are more common and can be easily found. Note: In the video I’m using 6mm bearing as well as threaded rod and GT2 pulleys.

Here’s a list of all main components used in this CNC machine. Now it already allow to simply and predictably create GCODE for parts like that (below).See also Best Budget Friendly 3D Printers for Beginners and Hobbyists Assembling the CNCĪnyway, now I have all the materials ready so I can start assembling the machine. Its good idea to make separate routes for inner cut, outer cut and side cuts, then select them in willing order and make GCODE for CNC.

To generate GCODE, you need to select route (or number of routes in needed order) and execute 'MakeGCODE' command. Route - Set of objects above, selected in proper order. Move - Something like path, but offset (X, Z) from point (usually from path endpoint). Rotation - rotate table by given degreeĥ.

Exit - same as enter, but reverse directionĤ. Enter - Move to entry point on safe height and then enter pathģ. Path - Cut movement by curve-curve and point-curveĢ. Simulation is very simple to implement, but this feature just interesting and really not very usefull.ġ. Also I'm not satisfied with workflow, user experience, and algo for path generation, so thats a reasons for me to create my own set of tools for hotwire. I know NiCr workbench and it 'dead' not only because it not works under current FreeCAD versions, it not fits my needs like handle 5-th axis (rotary table), wire on/off, and dynamic wire power management.
