this is a project i started so i could try to learn 3d modelling and pcb manufacture

I still know very little about either

here is a diy pendant you can make at home

would be cool to see the modifications people could do. I'm not sure what to do with the 2 potentiometers

the 3d print files and pcb gerber/bom/pnp files are in the repo. i have 4 extra working pcb's if anyone wants to try this i can probably send them to you.

not sure if i'm going to continue development with this but seems to work well

easy to install in mach 4 with self installer .exe program. includes a mach 4 wizard for pendant io status

the installer program will overwrite inputs 51-63 in the mach4 input config. it will also overwrite MPG #11 in the mach4 config

use the latest release of mach 4 or else

two separate firmwares (bluetooth or modbus)

ah crap. reupload assembly video: https://www.youtube.com/watch?v=5fpQ3xS1Tu8

wouldn't recommend to use something like this, due to safety. i've only tested on desktop cnc

added some beefy 18650 battery cells. clocked it in standby mode...about 21 hours, from 4.2 volts to 3.8. reversed the programming port and new MPG Bottom case .stl file to fit. added a lower screen bracket and battery cells .stl file. magnets won't hold this version up.

Looks good, i'm planning to do something similar, but using an arduino for keyboard emulation and to connect the pots
