CNC Hat for Raspberry

Post by techdesk » Mon Apr 22, 2019 10:13 am

We need to know
1. What speed can we expect (200khz,400khz or 500khz) from this CNC hat?
2. Can we connect our 542 and 860 microstepping drivers so that we can use larger stepper motors?
Can we stack these hats to allow more than 4 stepper motors? :?:
Regards to all

GRBL is rated up to 30khz...

Yes.. We have an external driver board that allows you to use the green screw connector as signal pins.

No, GRBL(Firmware) needs a serial connection to listen for commands. The RPI only provides one serial port.
Other hats can however be stacked under the CNC hat..
