backplot a and or b values

[motor-vater]

My question of the week. Is there a way to get backplot to display the rotational values like it does with X,Y,Z?

 

 

[JParis]

There is not, no,

[Chally72]

Just to expand a bit- that requires knowledge of the machine/post, and is outside of the scope of backplot.

No, there is no way to do that Pete.

Let me explain...

No, that is too long, let me sum up...

********************************

Mastercam is a "toolpath-centric" CAM Software. That means there is no "kinematic knowledge" of the machine's capabilities.

All 3-Axis Operations are "Toolplane Based". This means there is no rotation information present at the NCI Data level.

All Operation are output with a Toolplane Matrix (9 variables, 3 variables for the endpoint of each Unit Vector). This Toolplane Matrix is compared to the WCS Matrix (by MP.DLL, based on Post Settings (rotaxtyp$)). MP.DLL then uses Vector Math to calculate the Rotary Angles.

This Rotary Calculation is only done inside the Post. This means the Mastercam System has no idea:

1. What particular machine you will run this job on.
2. No idea of the stroke limits of the machine.
3. No idea of what the actual kinematic configuration is, so any given "machine mode" must be activated using a method like "Misc Values", to send a flag variable to the Post to indicate "what mode is active".
4. The "Machine Simulation" included with Mastercam is generic, which means that it also runs off NCI data, and the machine moves do not correspond to the moves in your Posted Code. There is a new(er) option that is available, where an authorized Post Developer can "hook up" your Post to a given Machine Sim module. This is a "per post" deal, and the revenues are shared with Moduleworks (required).
