Hi all. I have a xyz ct65lyt running siemans 828d. I'm trying to find a m code to use the hydraulic tailstock to advance to position with a live center. Tried many m codes but nothing moves. Any help would be appreciated
Thanks Brian

Under what conditions are you trying to run the M code ?
Are you wanting to advance the quill or tailstock body ?

You may not be able to move either with spindle turning

If via program... it may need to be advanced to a set position before any run command can be executed. Or it may need an addition M code to ignore an alarm condition (ie limit or pressure switch triggered before a spindle start can occur).

I don't know the codes, we use Shopturn to program a DMG lathe which controls the tailstock body positioning.

Sorted. Tried for a long time using G and M codes to no avail. Then found in shop turn there is a cycle which is very easy.
