Thank you for the explanation.

Is there anything you do not know about Centroid ?

AFAIK, the spindle on/off is currently controlled by a relay in the SB control box. It looks like the docs show rotation direction is controlled with relays...which is sub-optimal. I will absolutely investigate with those two M codes and report back. Thanks for that. Unfortunately, it may be a coup...

Would gearing the motors to spin faster be a good solution?

Cheers,

If the motor is only vibrating at very low speed, gearing would avoid this low speed on the motor, so it will run smooth while cutting with the same feedrate it is now vibrating.

It works with threading also

But why is G10 on the lathe different than on the mill ?

Mill : G10 P980 R1
Lathe : G10 P1980 R1

Even single axis Acorn is full CNC. If the axis is konfigured ok, you can set Z 0 for the lowest point and use MDI with G1 Z0.5 F200 to drive exactly 0.5 above the lowest point. Since Acorn is with one encoder port ist is possible to connect a scale. I am only not sure if ultimate is required for cl...

Yes they are cheaper on Ali, but not with next day delivery on purchase or in case of guarantee...

Nice, I hope this will be implemented in the mill version also

Test on my lathe

D14 1.4404 steel ap0.5mm F0.25mm S2500 min-1, turned down to 12mm, Z0 140mm in front of the chuck

SSV with 1.5s +-200 rpm

I would say a significant improvement compared to turning without SSV.

I am using JMC AC Servos for axis and spindle, they work very well. Uwe Where is your preferred place to buy these? Do they have a decent programming software and documentation ? How is the auto tuning? Currently have some ethercat delta B3A servos. I like that they have STO and allow me to use aco...
