Sure it is possible:



But not with G112, you have to use CAM or for such simple shapes a spreadsheet.

Uwe

Do you have a manual from the servo driver?

Uwe

I think it is possible to build a SSV function in the PLC...

Uwe

Without the g-code file it is difficult to help you...

Uwe

I do not think it is a software problem since my lathe is turning without visible steps.

I would try to use sharp inserts and play with U W in G70.

Uwe

My lathe is with XZCY axis, no problem for Acorn6 Lathe ultimate version.

At the moment G2/3 is not running in XY plane, but short vector linear moves will work to mill arcs.

Intercon is only for 2 axis, you have to use CAD/CAM or handcode

Uwe

Not sure what you want, the machine on the pic do not have a real Y axis.

But with a C-axis you could interpolate a Y-axis.

C-Axis will be the third axis on a lathe.

I have made a PP for fusion to do this on a lathe with Centroid CNC

Could also be a problem with rigidity tunning... I use 1 turn/2.5mm on my machines to keep the servo rpm higher = more power while cutting and they run butter smooth, no vibrations. I tune rigidity till they jitter and then back off the settings a little bit till they run smooth and hold a position ...

Looks like this is tied together with your analogue out problems

Uwe

For the spindle a KBSI-240D will do the job.
