Hello,
I just recently got my mill some what up and running. I'm in the process of running some parts to test how everything is work. I have run in to a problem with feed holding while in an arc move. If I feed hold in an arc move and try to cycle start to continue the cut the cutter ends up moves in random directions. Mostly it seems to takes off in the + Z and -Y and -X directions. I thought that this may only be related to doing a helix move but it also does it on a basic 2D profile arc.
When this happens I get and "Radius to end of arc differs from radius to start" error. From what I have read this error seems to happen the most if you Mach and your cam software are not post arcs the same way. INC vc ABS. I have checked and have both systems setup as INC I also have my code output a G91.1.
This is with the latest lock-down (.66) version of Mach3. My system consist of ESS using the latest lock-down plugin (10hd2), PMDX-126, PMDX-107. This system is on my knee mill.
I have spent some time browsing the forums and the yahoo group and have seen some post about this problem but none of them have a solution and they are quite old.
What I find some what odd is I also have Mach on my router and I can feed hold and continue any time I want on it with no problems. On difference is the router is a PP system and not and ESS system.
Any suggests other then trying to run my knee mill as a PP system with out the ESS?
Thanks
