I've been running my 3D router with a fixed speed spindle motor and set the speed in the tool section at 3000rpm. Everything worked well.
I'm now using a 3phase motor controlled by a VFD and this works OK using the tool stting window up to 10000rpm. My spindle can run up to 18000 revs but when i input this I get the title message, "Spin too large; check machine ID file".
I can't find the file to change!
I'm using LinuxCNC as a controller and with the exception of this speed issue it works great with SolidCAM.
I can change the gcode manually to give me 18000 rpm but that defeats the object.
Help please.
