For machine control, the PicoMite with BASIC is extremely capable.
I was troubleshooting the highly regarded Heidenhain TNC151 (CNC) on a Bridgeport Interact-4. I have all the documentation and Gemini provided further details.
Long-story-short, I came to realize that a single PicoMite RP2350 can easily outperform this entire controller, including HMI, without breaking a sweat.
I then researched a Trumpf laser (BIG) that features the Siemens 840D (very popular).
Same thing
Both CNCs run their PID loops at 4ms (250Hz). We can achieve 1ms (1KHz) on the PicoMite. I am not too comfortable with the CPU load when running more than four axes (4 PIDs) but at 2ms (500Hz) we have lots of spare power.
The trajectory planners run much slower which is nothing for the PicoMite.
Aaaannnnnd....We have an onboard code editor
Mind blowing
