Hi, sorry no plans for any digitizing!

4/5 axis probably about a year.

Hi Hood, there is no time limit for the demo, the only restriction is that no Nc code is generated

Cheers for all your help!

Thanks guys,

I will give the user a choice to pre select both ways!

Hood, yes we do plan on a Lathe version, but we want to develop the milling until it is more mature before we do.

One last question, is rigid tapping available?

Hi, thanks for the replies.

It looks like G44 is not that common, does anyone use this? Should I add this property for the sake of completeness?

Quote
Normally preselect isn't done but a user can if they wish write a custom macro. As the M call will be dependant on what the user decides to call the macro  then probably best not to have that option, unless however you can add an option for the user to input the M number. It will be in the format of M***P(Toolnumber here)

If I use M***P(Toolnumber) and allow a number to be specified is P the only letter that can be used?

Quote
The M6 macro will determine what happens here.

I guess then I should add the option the return the head to the tool change position in case the M6 macro does not do this?
Would you typically expect to see a G28/G30 Z0?
Is G91 in conjunction with needed as per Fanuc?

Thanks for your help

General Mach Discussion / Post processor for new CAM system

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.
