Robotpark MF-70 CNC Kit is a kit produced by Robotpark to convert manual micro milling machine Proxxon MF-70 to a computer controlled 3-axis CNC milling machine. The kit includes stainless steel motor mounts to connect the stepper motors to the hand wheel, one NEMA 23 stepper motor for each axis, a boxed electronic control board for computer communication and a 24V 5A power adapter.
By using RobotPark MF-70 CNC Kit, you can perform all milling processes that Proxxon MF-70 micro milling machine can handle, easier and faster. In addition you can perform milling processes which cannot be performed by hand. You can even produce your own printed circuit boards.
The CNC milling machine created using Robotpark MF-70 CNC Conversion Kit uses an open source CNC motion control interface called grbl. By using grbl control of your machine is handled fast and smoothly.
Setting up Robotpark MF-70 CNC Kit is pretty easy and straightforward. The motor mounts to connect steppers to the hand wheels are shipped assembled. You only need to mount the steppers and connect their wires to the electronic controller board and power the machine. After connecting the boxed control board to the computer via USB, you are ready to go. A comprehensive guide for setting up Robotpark MF-70 CNC Kit can be found here.
After the setup, using Robotpark MF-70 CNC Kit is also very easy. All you have to do is to use a program of your choice to send CNC commands called “G-Code” to your machine over serial port. RobotPark recommends Universal G-Code Sender. You can download the free software here. By using Universal G-Code Sender, you can send G-Code lines one by one or send a long G-Code program depending on your choice. You can also control your CNC machine manually by keyboard commands via the software.
Note: The kit does not contain Proxxon MF-70 micro milling machine.
