PROXXON MF70 MILL CNC CONVERSION
So, for the software I am going to assume some knowledge of downloading and installing software on a PC/Laptop.
If you're really stuck just ask for help.
You need to download and install three packages.
The first is the Arduino IDE to talk to and upload the GRBL software to the Arduino.
Get it here and follow the instructions to connect to the Arduino Uno.
Next download the GRBL installer from here https://github.com/P...hive/master.zip unzip the folder and move to 'Documents/Arduino/Libraries'
Start the Arduino IDE and connect to the UNO.
Under 'File' - 'Examples' scroll down until you see GRBL and select GRBLtoARDUINO
(if you don't see it goto 'Skecth' - 'Import Library' - 'Add Library' and Select GRBL from 'Documents/Arduino/Libraries')
Click on the 'Upload' (right arrow) button. The GRBL code should compile and upload to the Arduino Uno.
Next Download and install USG Platform (Universal G-Code Platform) from here http://winder.github...bsite/download/
Start the UGS (ugsplatform64.exe)
Select the COM port the Arduino is connected to and click on the 'Connect' icon.
You should get the status of the GRBL in the console window of the UGS followed by 'ok'.
If you get this far now is the time to plug-in the steppers (power off first) and try moving them with the 'Jog Controller' of the UGS.
but first you need to set the steps/mm for the three steppers.
The Proxxon MF70 has 1mm/turn on all axes and the steppers have 200 step/revolution, we need to set the step/mm to 200.
At the bottom of the console window in the 'commands' line type
We also want to limit the speed of the feeds so to start set them all to 50
Now try the Jog Controller.
Set the 'XY Step' and Z step to 1
clicking on the X,Y and Z buttons should now move the steppers 1 revolution and if connected to the MF70 move the table/height by 1mm.
You now need to generate some G-Code and load it from a file in UGS.
I use Fusion360 (free to download from https://www.autodesk...360/free-trial)as it has a GRBL driver in the CAM to generate the G-code in the correct format for the GRBL interface.
Download the free trail and register for non-commercial use to extend usage.
Lots of tutorials on YouTube. Or you can use your favorite CAD/CAM.
Good luck, and if you get stuck just ask.
I'll try and upload some screen shots later with a video of the system in operation.
