5 axis Post processos
(OP)
Hello. I have (i made) my own postprocessor, which is working well on any axies (when i mill something directly on any rotated axis). Now i started ti check how it is working when i'd like to mill a 3d surface, with a multi axis moving, but something wrong, and the tool is go to a wrong position. I am sure something is wrong in my post, but i didnt find yet.
Is this any special command what i must use in this milling type?

When using M128 or TCPM coordinates are relative to the part and not relative to the machine.
The coordinates need to be mom_mcs_goto instead of mom_pos.
Initital coordinate before you switch to M128 should be in machine coordinates.

The rapids will need some adjustment too in multi-axis mode because xy z sequencing will in some cases damage the part.

I found the basic problem. If i just make a save without any modification from my "basic" post, my newer post builder modify almost every command and prompt in the post, thats why it's started to be wrong. :(
