I am using Solidworks to design my parts and I have the add-in MasterCAM for Solidworks to build my tool-paths and output my g-code. I've tried adding in the MasterCAM X8 post-processor for Mach3 to output my files. I recently saw something about using the update.dll in C-hooks to update the post-processor and I haven't tried this yet. I will be trying it tonight , but I wanted to get this out there to see if anyone knew of a way to get the output for MasterCAM for Solidworks formatted properly. I have noticed that when Mach3 reviews the code in loading that it hangs on what is probably the first IJ command and I wanted to also know if Mach 3 doesn't do IJ interpolation. I've out-put as a standard FANUC post format, and I still have this problem. Could I remedy this by setting all my output to incremental? Just throwing out ideas. Hopefully someone on here knows how to get the correct post-processor for MasterCAM for SW working and I can solve this issue. Thanks. http://msk-door.ru/mastino-line-3/
