That line for instance codes for a circular path in the ZX plane, beyond the current capabilities of the Maslow.

Thank you blurf! Changing to grbl helped but new problem popped ;-(( Many messages like “Oops, calculation cause error… send G1 instead… bla bla bla” But more important - Z is wrong. I am trying to cut profiles from 3mm MDF. Within Fusion all looks good: simulation is OK. Z in gcode is Z0.6 ??? If I only solved this Z issue I should be fine. I also tried to download Maslow post but how to instal it !!! I am running Mac version of Fusion - all tutorials are on Win platform ;-(( Under OS X there are no option to point to custom post) Is there any free gcode program which accepts dxf and generate gcode acceptable by Maslow without errors? (FreeCAD accepts only graphics) ---

Is your Z all + in the g-code? Could that be the point of origin? > [@Fusion 360 confusion](https://forums.maslowcnc.com/t/fusion-360-confusion/3565/4): > > Fusion does have some issues. It can be a bit buggy, and I have fights with it sometimes when I’m laying out a sketch. The way it sketches reference other elements is a little tricky. Then again, I prefer Creo, which (I feel) handles external references much more gracefully. Sketchup makes me shudder though. I’m sure the modern version is better than when I messed around with it, but I really don’t like the interface myself. Each to their own. Anyways, onto the code! So some interesting thin… ---

Would you mind changing the title to reflect the actual issue? (mac-\>fusion360) That will make it easier to find for others with the same issues. I was wondering how you run F360 under Linux 🙂 ---

To make it clear: I am running Fusion360 on Mac OS X High Sierrra 10.13 on separate machine. MiniMac is converted to dedicated Linux station and runs GroundControl 1.13. Both machines are on the same wifi network and file exchange is not an issue. Linux see shared folders on Mac. I will contact Fusion guys to solve loading Maslow post into Mac version of Fusion CAM. As blurf suggested, I am using grbl post for now and it is working fine (with couple of unsupported commands ignored by GC). Fusion CAM is complicated but once I figured it out it is quite good - smooth workflow from design to parts, to gcode within Fusion is priceless. Working in the same environment gives you consistent units, consistent orientation and so on. It would be great to have Maslow post in Fusion library - at the end simpler gcode and less chance for screwup. (We should have it here [Post Library for Autodesk Fusion 360 | Autodesk Fusion 360](https://cam.autodesk.com/hsmposts) ) Thank you Gero for tip with Point of origin 😉 ---

I’m glad to hear that progress is happening! > [@TomD](#): > > Many messages like “Oops, calculation cause error… send G1 instead… bla bla bla” Those messages are a bother - they mean that the program that made the gcode used many tiny imprecise arcs to make a curved cut. Software precision limits would cause the Maslow to cut these wrong, sometimes very wrong. The firmware looks for those and changes the, from tiny arcs to tiny straight lines. The difference shouldn’t be visible in the finished cut. The message is the firmware telling that it has changed the command it received. ---

In Fusion360, I believe the ‘smoothing’ option in the 2D Contour menu will help prevent this by tieing in the small arcs into a smoother, longer, curve… hope this helps,
