Hi Guys:
Sorry, I only just caught this thread. You dont need anything after a G41, the currrent tool will be used, You can use the P to sepcify a diamter, or a D to specify a tool to get the diamter from.
Radius comp has had alot of work done to it lately, it was buggy on some file before. Take note there are two modes, the original mode is selected in the config/ports&Pins/mill options, or you can select advanced comp. Advanced comp is easier to use, it does have as many rules to using it, but it was buggy for soem file types, depended alot on the moves. Always simulate a comp program offline first to be sure it isnt opne with trouble. Send me any tap files that are a problem, its how I fix the comp, I keep tweaking it to recognise that code..
Thanks
Art
