Note: If you wanted to use LinuxCNC (a Linux distro) instead, you would need to boot up the PC to Linux. Note that this document does not cover LinuxCNC at this time. It is not configured and you are on your own on that one. | |||
Also: we are working on an Arduino interface running GRBL, which will allow you to run other front end programs. As of this writing (Aug 28, 2021), this is a work-in-progress. | |||
The ER11 collet we currently have only accepts 1/8' bit shank. Maximum spindle speed is 13,500 RPM. The speed is controlled via a dial knob. As Mach3 can read and adjust spindle speed, but this feature is not currently implemented. | The ER11 collet we currently have only accepts 1/8' bit shank. Maximum spindle speed is 13,500 RPM.

All old limit switches got replaced, soft limit settings in Mach3 are in place. Please keep soft limits on. | All old limit switches got replaced, soft limit settings in Mach3 are in place. Please keep soft limits on. | ||

After calibration, we tested the machine with 2D Milling operation (Nested square pocket) and 3D Milling operation (Dome shape) and it churned out shapes nicely.

I suggest that you keep the speed & feed rate conservative (i.e make it slow) and see how this machine plays with various materials, both wood and soft metal. I have no idea whether or not we can mill Aluminium chunk with this little bugger without wearing it out *prematurely* but I'm not an expert on this so your opinions are more than welcomed. | I suggest that you keep the speed & feed rate conservative (i.e make it slow) and see how this machine plays with various materials, both wood and soft metal.

The machine runs on Mach3, the same software previously used on Tormac. Anyone who knows how to use the Tormac, or know what you are doing, or can hit E-Stop fast enough, or well, is curious enough and want to play with it, are welcome to use the machine. | The machine runs on Mach3, the same software previously used on Tormac.

While noise is not much of an issue, this machine can generate lots of fine sawdust so you need to stand at the machine, pointing the shop-vac hose right at the spindle to minimize the dust. I think a machine of this size and weight, an enclosed box for it is manageable. | While noise is not much of an issue, this machine can generate lots of fine sawdust so you need to stand at the machine, pointing the shop-vac hose right at the spindle to minimize the dust.

* | |||
*02/29/2020: Bought 2" x 5/16 stove bolts to replace M4 on hold down clamps. | |||
*03/03/2020: Replaced (added to inventory?) shorter bolts to hold down clamp. Ground heads down to allow them to pass the Allen head screws holding bed down. | |||
*03/07/2020: Updated GRUB config to remember last boot OS | |||
*03/10/2020: fabricated and installed registration strip out of acrylic. Aligned with bed to be parallel with x axis. See [[:file:141-registrationstrip.jpg|'''Picture of Registration Strip''']] | |||
*03/28/2021: Configured Desktop Shortcut to automatically run the profile "Mach3Mill (Metric)". Also added a "No Profile" shortcut if you want to select your own version. | |||
*03/28/2021: Configured Spinal On/Off. Use F5 to turn on/off, or click on the Manual Speed Control. | |||
