Need Help!- Processing Problem Rhinocam1 to Mach 3

Rhinocam1/Mach 3 Post-processing problem

--------------------------------------------------------------------------------

Hi,
Apologies for asking what is probably a pretty lame question, but I am a newbie using Rhinocam.

My frustration is, when I post-process my finished part, in this case a simple block ready for 2 1/2 axis profiling, the G code generated using Rhinocam1, when loaded into Mach 3, produces a different output size.

For example the length of block in Rhinocam1 measures 24mm (approx. 1") but when it loads into Mach 3 the G-code produced makes a block 190mm (approx. 7 1/2") long.

Has anyone had this experience before or more to the point what have I missed or doing wrong?

Thanks in advance for your assistance.

The first thing that springs to mind is you have your steps per rev set incorrectly.

You should have tested your machine first hopefully so that from the MDI you put in a very long travel command and check that it has moved that amount accurately.

This needs to be done for every axis.

If you haven't i suggest you start reading the Mach3 forum there are masses of tips you will find it hard going at first but its the only way to learn from others mistakes.

Phil,
Thanks mate for your reply. All I can say is dah!. That's what it will be. I did mess about with the motor tuning early this morning, some 18 hours ago. It's now 12.45 am here in OZ and my frustration is doing my head in.

I think on that note I will stumble off to get some shut eye and continue (refreshed) after re-setting the motor profiles.

Thanks again Phil.


Cheers
Phil
