Z Height in CNC Simulate goes through workarea

Hello Fusion Team,


I am a novice in CAM design with fusion 360, I own a genmitsu 6050PROVerXL that I still have not got to run with fusion 360. One of the issues I'm finding is that during simulation of a new project I simulate the operation and for whatever reason the CNC goes -700 below the Z axis travel even though in Kinematics I've told it that the max range is -115mm. I've had it on one project work like a charm and when I try it on the next I get this issue, I don't know how to solve this.

Not sure which aspects of my settings people want to see, but I imagine this may have something of interest. I have the bottom height at -1mm because I want it to cut all the way through and it wasn't going that at 0.

my x and Y settings are like this and have no problem

In the machine builder the z axis seems to be fine, I know for a fact I did not ask the CNC to go -761mm below the work bed.

Please help me find an answer, when I did it with another design I didn't have this problem but another being "Z-overtravel" which I didn't understand, but looked like the design would work when I tested it on my CNC without a drill bit. Only issue i had there is that the machine was cutting in the air, I probed it from the material I wanted to cut not the MDF board it was sitting on which I'm guessing is the problem.

It looks like you don't have your machine/setup defined correctly.  Would you be able to share your Fusion file here?

No Problem, please find it enclosed below. 

Just mind you this is nothing other than a test carve for ABS plastic sheet being 3.5mm thick, It could be any shape or object within 80x80mm space. Trying to find out the best settings to carve into ABS.

Hey Seth,


have you had any luck? do the settings I have on the f3d file actually transfer over to you? including how my machine is set?

I should also mention when exporting files back when it worked I had issues with the safe retracts and home positioning. For whatever reason whether I choose G28 or G53 it shoots the z axis to the hard limit switch and causes the cut to fail. I've had to get around this through selecting clearance height, but hoped maybe you would find something interesting whilst trying. to find the other bug.


Here as well in case you need it is the manuals specifications page. 

Again, thank you very much for taking the time, you're saving me big time with my job.
