General Mach Discussion / Post processor for new CAM system
« on: August 26, 2009, 08:39:07 AM »
Hi, I hope you can help me. I am creating a post processor to suit the Mach3 for a new CAM system to the market, SharpCam:  http://www.sharpcam.co.uk/

We have a technology that sits on top of the post that allows the user to configure simple properties to suit there machine. This means that one post can cover many machines that have subtle differences.

For example a see from the documentation that arc centres can be specified in to ways, incremental or absolute. This is a good candidate for a configurable property. The user can just selected their choice from a drop down box.

I have a few question that I hope some of you guru's would possibly be so kind to help me with!


This is by no means an exhaustive list:

1.   I note the G43 expects tool length offsets to be positive. G44 for negative offsets. Should a choice be given for both? Is it common for users to use G44.
2.   Should an M6 be output regardless of the machine, I note on the ‘General Logic Configuration’ dialog that the ‘Tool Change’ group box seems to cater for all scenarios even if the machine is not fitted with an ATC.
3.   Can a tool be pre selected?
4.   Do an M6 always return the Z axis to the ATC position or retract and stop for a manual tool Change?

Thank you very much for your time.
