I'm getting PS 5421 ILLEGAL COMMAND IN G43.4/G43.5 in O0999 which had an operation before the concerned block. However I posted the selected operation separately in O0998 and I worked just fine. I'm unable to figure out what the problem is as the codes are similar.

Is there a setting that can be changed to post spindle direction(M03) after every speed(S####) command?

The direction command is only output on the start of the toolpathz(for eg S#### M03), if there's a speed change mid operation mastercam just outputs (S####). How can I have S#### M03 everytime.

I'm trying to create an engraving toolpath using curve 5 axis, curve type is selected as surface edge, tool axis control is surface and tip control is on projected curve. It is able to generate valid tool path for most of the letters however for some letters such as T it is not generating correct toolpath. how can I fix it. I have tried using 3D curve as curve type and it didn't work as well.
