Twin turret lathe configuration

Actually this machine will do the very same movement in a mirrored fashion on the Z W axes. But will use two tools so need to set up two compensation points.

So im thinking on writing a wrapper, which will simply negate the W axis, but it might not be hard to copy the XZ Params and turn them into X->U -- Z->(-W)

The tool offset table in Linuxcnc has separate columns for each axis. So if you are always using the same pairs of tools together then you can simply have the Z offset in the Z column and the W offset in the W column. (If tool 3 in the Z is always used with tool 3 in the W.) If the pairs of tools are not always the same then you will need to use a separate tool position for each, one tool with the Z offset in the Z column (and no W) and the other tool with the W (in the W column but no Z), then add the two tool offsets using G43.2. The same for X and U if needed.

Is this a railway wheel lathe as was discussed a while ago?

Yes, it is a railway wheel lathe. Just didn't know how it is called, and approached the problem on a more generic way.

Thanks for the link, I will read it out.
