Looking for help on build
Hi all I have a issue with an CNC controller I am trying to use https://www.nvcnc.net/smc4-4-16a16b.html
Got via eBay and is driving a router table from same source.
6040 Desktop CNC Router Engraver Milling Machine 3-Axis
Issue I have is I can drive via the manual buttons but will not run though a DXF file
Have had the DRO scrolling but no drive to the motors
I am assuming I have to set some thing up first but not clear in the book
Also has anyone using this controller that has a DXF that works in it so can test what is the issue?
Thanks for any help John
The first few lines set some parameters and are machine specific, there are many different flavors of g code just as there are many different machines. For example, your machine has 3 axis, is would not understand a command to rotate the A axis which does not exist.
then there is one “M3 S15000” which turns the spindle on at 15,000 rpm
Followed by “G0 X0.001 Y0.001 Z0.050” which tells the machine to move all 3 axis to a specific location.
There are specific software programs to convert drawings, like dxf, to g code. They are called CAM software
Some are very simple and cheap or free, others are more complex and not so cheap.
I use V-carve pro from Vectric.
After I have created or imported my drawing, I then tell V-carve to generate the tool path. Then I tell it to save the tool path at which point I have to select the specific machine I am saving it for so V-carve can generate the specific g code file for that specific machine.
Do some searching for CAM software tutorials and you will get the idea.
