Need Post Processor for Mitsubishi EDM
Over the last two weeks I was able to dredge up 12 Mitsubishi EDM Post Processors for FeatureCAM. Since none of them specifically called out the W21FAS-2 Mitsubishi EDM machine, so I loaded each one separately and ran posts for a 4 axis taper project I cannot cut accurately ... even though the model and its sim look perfect in FeatureCAM.

=============================================
I was fortunate to finally get connected with an experienced Mitsubishi wire guy and he immediately pointed out that the U/V coordinates in the above posts are not "modal" and the post processor MUST output U/V parameters on every line even if there is no action in that plane. Each of the posts above violate that point in at least one line.
Since the geometry of my model and its simulation output are precisely on the money, but the Mitsubishi EDM controller check display didn't match, either the post processor was wrong or the Mits was misinterpreting the Gcode.
I gave my geometry to him and asked if he would gen the Gcode for the Mits since his shop used a lot of them for decades.
The code he produced, using another CAM software package, had U/V taper commands in every line AND displayed correctly on the Mits controller screen.

Besides displaying properly on the Mits EDM controller screen, his Gcode cut the model perfectly.
I really would like to chat with anyone using FeatureCAM that successfully can cut standard or 4thAxis Tapers to learn what post processor they use.
Best regards,
Bruce
