I want to be able to change the M6 Instruction to M3. I have been over this like a nasty rash and I cannot find where it is hiding.

Secondly my CamBam is producing Arc data to 16 decimal places i.e. 2.0133627727628013 is there a way to limit this to 5 or 6 places. I'm convinces this is what is making my UGS take a wobble.

Look at the documentation under Postprocessor
https://cambamcnc.com/doc/1.0/cam/post-processor.html

Options - Number Format
A hash character (#) denotes an optional digit place holder and a 0 character denotes a digit that is always displayed, adding padding zeros if required.

My setting is 0.00##
This means that two decimal places are always output and two more only when they are needed.
If you always want to output 6 decimal places you write 0.000000. All decimal places that are not used are output as 0, but they are always output.

If you write 0.00####, two decimal places are always output, but up to 6 decimal places are output if necessary


M6 to M3
M3 is usually the specification for clockwise spindle.
The M6 is in the postprocessor in the tool change macro.

You can open the macro under tool change and enter M3 instead of M6.
The postprocessor must then be saved. To do this, you should use your own name so as not to lose the original postprocessor.

It is very important that you not only change the M6 to M3 but also change the command for spindle clockwise from M3 to the command you want.
Otherwise there will be a conflict between the two commands

That's Magic ! Thank you so much. Cured my nagging M6 issues. Having said that I still don't seem to be to reduce the number of trailing decimal places in my settings. (I'm probably in the wrong place !)



When I view my settings files I still have


Am I in the wrong place? Is there a global setting for all coordinates ?

You seem averse to reading to the manual, Ralf posted a link to information regarding those settings.

Sorry, I misunderstood you.
The number format in the postprocessor only controls how many decimal places are generated in the G-code output.

This has no influence on the decimal places displayed in the program.
Due to the limitations of current computer technology, we expect an accuracy of up to 15 digits in calculations, in a range of ±10²⁰ to ±10^-20. This limitation is found in all modern CAD products.
Cambam calculates this precisely and also displays these decimal places.
Otherwise, several calculations would result in inaccuracies when rounding up and down, which would quickly exceed the precision of a machine.

I know of no way to reduce the display of decimal places in CamBam.
