Title:

Inverting the Z axis for g-code

Text:

Ok, been working on getting my first run out of Fusion, through the F360 Boxzy post processor, into the Boxzy Interface, and out to a finished part on the plate. The problem i’m finding is that the Z in the gcode is coming out as negative integers but my configuration is set with Z-down being positive. There has to be a way to switch this somewhere in the chain from CAM to control, right? Right? I’ve seen this same question asked in several forums with zero reply, so either I’m asking the impossible or this is so bloody simple that I should figure it out? Tell me it isn’t that.
 
Thanks!
 
=== Update (12/25/2018) ===
I’ve finally found the time to come back around to this. My WCS isn’t the issue, it’s that my Z axis on my printer is backwards. Here’s a crapload of screen shots to prove it out to you so that hopefully I can get the right answer and have this machine working how it should.
 
Here’s the a shot of the CAM (I originally had the work WCS in the position you recommended prior to posting my question, so I decided to try the opposite this time ) -

These are two shots of the simulation show solid tool paths for the part-

And last here is the first bunch of g-code. Please note the z axis-

When sent to the printer, the z axis moved away from the router instead of towards it.
 
So I switched the WCS BACK to the original one that I ran before asking this question - pic of the CAM set up, identical toolpaths as before except with the adjusted wcs and adjusted heights in the toolpaths themselves-

Heres the g-code for this run -

These were the post process parameters on both posts -

Aaaaaaaand, finally, here’s my manual control showing that my z axis is backwards and I don’t have a handy button on my interface that switches it like I’ve seen in other photos

Help would be appreciated, this is killing me
