I purchased a cohesion 3d board for my laser and I’am extremely happy with it. My neighbor wants to sell his Chinese cnc machine`to me because he has become frustrated with it. Does anyone know what kind of upgrade board these guys are using for a cnc router table?
The Cohesion3D laserboard is also a good board to use for a CNC router. It will work very well.
Heard that Duet WiFi is a good controller for routers also. I would go visit the CNC router forums. You will get better info there about controlling a router. Lots of things to consider. Cad/Cam toolpathing, post processing of the tool path GCode for different controllers, Mach 3, Mach 4, etc. they are a bit of a different animal.
The LaserBoard can indeed be used for CNC. The primary considerations are:
- Motor size and whether you can use the internal drivers or need external ones
- How to control the spindle
- Homing sensors
Tell me more and I’ll tell you more
The Spindle can easily be controlled with one of you pwm outputs. Most if not all Variable Frequency Drives (VFDs) can be operated with a remote DC voltage, normally 0-10 Vdc. You can purchase a simple PWM to voltage converter like this one to make the link
