is CN still writing the code even though it says there is a problem? if it is, you can scroll through the program and look for a message in brackets saying that there is a problem. that will tell you if it is a problem with a tool diameter or whatnot. should narrow down the problem.

Mark,


make sure that you have .5, .375, and .25 bits set up at the router.
For some reason router has a problem with the G-code if there is no tools with that exact diametar.
The same thing was happening to me and as i would scrole down to the part of the code with the problem it would say that the tool with diameter of .375 is nat set up in tooling.

Tim,

As the other gentlemen have stated in this posting, it is likely that there is not a tool of specific dia. setup in Tooling or Pocket Tool setup of Control Nesting. A couple general things to keep in mind when tooling your machine up for Control Nesting are as follows:

#1 - To cut Dado operations, C.N. must have a tool which can cut dado within two passes (down and back), also, the machine must be able to compensate slightly for tool being used when routing dado (ex: tool can not be exact dia. as dado, typ. .001\"-.002\" is enough undersize).

#2 - Plunge Drill type operations require that there be a tool setup which has a dia. (recorded in tool manager of machine <F10, F9, F2> that matches exactly same size of designed hole (in ecab or dxf file).

#3 - When defining d#p# in pokcet layer name (dxf files) for tool to be used in pocketing operation, be sure the exact dia. value is recorded in Pocket Tool Setup, under SETTINGS of C.N.

#4 - It is a good that when setting up Tooling for C.N., and checking the option Interpolate, that the Max Interoplate Dia. be no more than twice the dia. of the cutter setup for this tooling op. (this will eliminate leaving a plug while cutting circle). If perhaps there is a hole in need of interpolation, and there is not a tool with a large enough Max Interpolate dia., C.N. will fall through and select the Pocket tool Setup tool for the cut.

These are just some basic notes which can be helpful. I hope this has been helpful.
