Author Topic: Wrong toolpaths appear in Mach3 during running ESS with plugin installed  (Read 1365 times)

Hello everybody,

In the old day of using parallel port for Mach3, I found no problem in running all G-codes that were produced from Mastercam X5, these included all kind of 3d pocket, contouring, etc, etc.

Lately, I go to ESS, problem occurs in pocket machining. Firstly, the toolpath generates and are viewed all okay in Mastercam. However, when the output G-code file is brought to Mach3, some additional wrong toothpaths appear (purple color lines of first attachment). The Mach3 version is 3.043.062 and plugin version is ESS_Mach3_160630_u4f1b as recommended. When switching back to parallel port, those errors no longer appears. In another toolhpath of pocket parallel profile, the error message of 'radius to the end of arc...' appears as well (second attachment). These errors only occur in pocket machining profile, no problem are found for contouring, drilling, 2d contouring and etc.

I don't think the happening should be blamed to the postprocessor as it was used well for some time in parallel port environment. Also, I downloaded the recommended processor for the Mastercam from Mach3 website for use but it doesn't help in correcting those mistakes.

Can somebody help to give advice?

Looks like you have discovered the Crop Circles  :)
Goto   Config. / General Config.   and change the IJ Mode   then Regen. the Toolpath.

Ideally all Gcode files should contain the G90.1 or G91.1 as appropriate.

KEEP SAFE !

It's in the second column to the right of Distance Mode.
