ACORN - REAL-TIME feed rate adjustment from spindle RPM

Post by ALVARO »

Hello!

getting ready to convert to ACORN from my mach3 kASUGA knee mill conversion-


is it possible with Acorn to sense spindle RPM and then adjust feedrate acordingly (with some math)?

thank you!

Feed per revolution!
If you have an encoder on the spindle it works like a charm!

Yes. Parameter 78 can be configured to either wait for the spindle to each programmed speed before axes move and/or adjust the axes feedrate up/down as the spindle slows or speeds up due to load conditions
