HelloI've been working for a while on retrofitting a “small” Mecanumeric / Charlyrobot milling machine (the second one is the real manufacturer but they merged) at my work.
I work in a fablab in a high school in France. This machine has been at the school for many years, and originally ran on a Windows XP PC with specific software.The motherboard in the machine had a number of problems which I won't go into now, including a slightly scratched tool sensor.....I suggested modernizing it, making it more upgradeable and easier to repair.
So I had a few items purchased, including drivers and a Mesa 7i96S card. I reverse-engineered the wiring and managed to implement it pretty much as I wanted. The control panel was made from MDF using the big CNC machine, an Arduino using the great
Arduino Connector
project and a salvaged industrial touchscreen. I've added the ability for LinuxCNC to detect the opening of the cover to prevent the execution of a program. And to deal with minor oversights, I've added a relay to activate and deactivate the vacuum cleaner.
Finally, I've designed a small, unpretentious tool probe (which I can show if you're interested) with a microswitch and 3D printing.
