Specification | Value |
---|---|
Bed size (X/Y) | 48 x 48" Usable size needs to be verified. |
Height (Z) | Needs to be tested and verified. |
Spindle rating | 2.2 kW |
Max spindle speed | 24,000 RPM |
Collet size | ER20 |
Max feedrate (non-cutting) | About 200 IPM tried so far. Impossible to know, but would be good to publicly record a "known safe" travel speed for rapids to avoid mishaps due to assumptions. |
Host software |
For LinuxCNC workflow LinuxCNC 2.7.8 running on Debian 7.9 |
Electronic platforms |
For LinuxCNC workflow MESA 5i25 + 7i76, with HobbyCNC Chopper Driver (rev1) |
Stepper motors | Bipolar NEMA 23s with 425 oz-in of torque |
Dual Y axis motors | Yes |

CAD/CAM workflow notes | General information about CAD and CAM packages, with important specific notes on speeds and feeds and preparing designs for LinuxCNC |
End mills overview and usage | High-level overview of end mill characteristics, with recommendations for which end mills to use for different materials and strategies. |
Running a job (#1): machine setup and checks | How to make sure the machine is ready to use. Includes basic preventative maintenance and making sure that the mobile control station is all connected and powered up. |
Running a job (#2): securing workpieces to the spoilboard | Methods for properly (and improperly) attaching workpieces to the spoilboard. |
Running a job (#3): loading, preparing and running Gcode with LinuxCNC | How to operate the host machine software in order to interact with the machine. Manual positioning using jogging, loading and running G-code, and more. |
