MaslowCNC
Regarding the Maslow CNC, I'm still supposed to cut a new sled for it, but I think people can start using it if they like
I'm not very familiar with CNC workflows, I mostly just followed the setup instructions to get it to the point it is now. The firmware on the arduino is up to date as of yesterday and shouldn't need to be touched for now. The program that is used to control the machine is called Ground Control
http://maslowcommunitygarden.org/GroundControl.html?instructions=true
That link has the instructions for installing it and link to the user guide.
We don't have a dedicated machine for the Maslow CNC so I did the testing and calibration on my laptop. To share the results of the calibration, According to a note on the Maslow forums: *"groundcontrol.ini’ is the file you need. It is found in your home directory. The serial connection and the path to the .nc file will probably be different on a different PC*, but everything else will be the same." (edited)
Our machine has the z-axis installed, but you may want to double check that the zero point for it is correct. It looks like we load gcode files into ground control, so that file would need to be generated by other means.
Here is a link to the Maslow github: https://github.com/MaslowCNC
Please feel free to start using the machine. the caveat is that it the final sled should improve the accuracy of the machine once it is installed. The directions for the final sled are toward the bottom of this page: http://maslowcommunitygarden.org/Maslow-Ring-System.html?instructions=true (edited) The manual and wrenches for the rounter are in the orange/black nylon bag under the machine. There is also a vacuum attachment for the router in there.
Here is the groundcontrol.ini file from my laptop (returns added for wiki formatting)
