Z axis out by 2mm mach3 or fusion360 problem?

[JAZZCNC]

Sounds like it's your Cam (G-code) but unfortunately, I don't use F360 so can't help.
However, if you want to check your moving correct amounts regard steps per then Zero the work Coordinate then goto MDI type G0 Z10 (or any amount you prefer) then measure to see if it moved this amount. Then G0 Z0 and it should go back exactly to point you touch off at.

If this works then it's your Code.

Thanks for replying mate, I tried all that before I posted lol, I'm assuming it's a 360 issue but I have been trying for a few days now with no look, stressful is not the word ��

Hi Richard youtube is your best mate with this, there are also lots of tutorials there also. hope this helps

[Richardtweed]

Yes I have learned heaps from YouTube but I am struggling to find a video on this matter

Then it's not Mach3 which answers half your question.! . . . There is one other possibility.? Check you don't have a tool height offset set in tool table.

can you make a simple program such as a 50mm square part, face it off and post the code so we can see what fusion is producing

[Richardtweed]

I will do that now as I'm still trying to fix it, its driving me crazy. I have played about with the hights in fusion 360 with no look. Mach 3 is showing it to be 2mm above the zero so it knows where the end mill is at least.

I ran a test piece and it cut everything fine so a copied the hights I used in 360 that were pre-set and used them on the work I am having issues with and it still started cutting 2mm above the z axis zero height which has frustrated me even further, the readout on mach3 knows it is cutting +2mm
