Hi folks
I have a simple chinese 6040 router table and I use small manually interchangeable bits - as I mainly cut small scale wood pieces. I design the work in Fusion 360 and spit out the code from the CAM section.
Im having a problem with changing tools - and getting errors in z heights in the cut.
I typically split my code into per tool blocks. My basic process is as follows:
With the bit back at x-0, y=0, I change the bit manually - and then Set the z height of the bit - using the slipping a sheet of paper under the bit end method ...
I then click ref all home to zero the new z value - and check that z value is 0 as I toggle the machine coords button. If either isn't I use the zero z button. .. I then region the tool path .. and then I continue the cut ..
Trouble is something is going wrong and Im getting errors of in the overall z value - sometimes as much as 4-5 mm out. Whilst I set the dimenesions of my tools in Fusion 360 Im assuming that it thinks every tool gets zeroed before use - i.e. that the error is in how Im using Mach 3 - not the CAM package.
Any ideas what Im doing wrong? Would much appreciate your assistance.
Cheers
Keith
