Just taken delivery of:
XYZ TC 320 LTY Siemens 828D Lathe
Siemens 828D TE61
NCU Software V4.05 SP6 HF02
XZ+YC live head lathe

Had the training on Shopturn, impressed, very capable.

As with all conversationals very quickly hit a job which needs more customisation, time to get back into the ISO

Lots of PDFs for simple XY stuff but struggling to find documentation to get me started on the fundamentals for the C axis control - the header code to activate and home C particularly, example code etc. (on my Fanuc I activate C with G28?)

Current job is 3 open slots from the end of a tube - go to X depth off the end of the tube, G1 to Z length, rapid out, C to next position, repeat.

Cheers, Sean
 
try this, how the 840d is done but should be very similar

Cheers, the unfamiliar bits are the Siemens codes - SETMS SPOS - do these have iso equivalents or do I have to learn the Siemens? Sean
