thanks for the link i had already created a spreadsheet that converted the Y to A and then scaled it to degrees.

i was wondering really if there was a function i mach at did it as it is half way there as it does carry out radius feed comp.

I thought there could be something like Cycle800, triore, or tilted working plane that would map it on the controls.

I am thinking of ways to machine on the outside of a ring/diameter using a rotary axis.

1, Take XYZ path substitute A for Y then reconfigure the motor to rotate based on the circumference of the machined diameter.
2, Run machine with the A configure as in Y and rotate based on the circumference of the machined diameter.
3, Scale the Y axis into degrees by a factor given the circumference of the machined diameter.
4, convert the Y values in degrees by Y /  circumference of the machined diameter * 360.

Or is there another way?

Gent's and ladies

I have been using mach for many years but just using the base co-ordinantes without using G54 or G28 commands, I don't see the need to run them on this machine as i don't have multiple setup on the machine and no repeatable tooling for length.

anyway i have switch to a different cam which uses g28 and g54 and i have a lathe setup and mill setup on the same machine.

When i exit and save fixture and reload it now does not remember the position.

Or is it just showing the g53 and not the g54 wcs?

thanks matt

Thanks Hood,

once again i found out a new thing about mach, i thought it would select the last installed not add it to a list that you can select from but remains hidden unless you know exactly what you are looking for.

I have reloaded mach from scratch by deleting the config xml's and set up the machine again. This has sorted out the axis doubling and backlash is working.

however it appears that when jogging the backlash com is not applied. Is this correct?

i also think the issue before was that the new plugin was not being applied as i don't let mach ask me each time what to device to use as a pulse stream.

by the DRO's the scaling factors state 1.0

Sorry, i did not make it that clear, the DRO's move to x20 y20 when i have g1 x10 y10 i was not talking about the real world position which would be dependent on the steps

the steps could be wrong but when i use MDI and request x10 y10 g1 f100 it positions it to x20 y20 which makes me think that it is in diameter not radius. i will post the xml latter.

i cannot get the SS to work with back comp, do you have to come out of constant move mode?
