After a tremendous quantum leap in knowledge and a huge learning curve I am almost ready to put my efforts to work in drilling lots of PCB's. I am using the Nesting Wizard which Mr Hood pointed me to. I have created several Nest routines which will hopefully drill six boards per pass then I need to change the bit to go over the same six drilling the larger holes. - I am really pleased with my efforts but once again I need a little help.
The feed-rate at which the bits drill needs to differ, so in my wisdom (or folly!) I created my nested routine for the 1.3mm holes as:
Y34.2000X11.7560F200
Z-2.5000F100
Z-6.4000F25
Z3.0000F200
M99
The logic being to drop the bit 2.5mm at 100% rate (I think this is called the plunge rate) then drill at 25% then withdraw at full rate. Well to me it sounds good, but it doesn't bleedin well work. What the Hell am I doing wrong?
Secondly, is there any way to have Mach3 inform me that a tool change is needed? I have put M6 T(n) onto the top of each Nested Routine. The T(n) in this instance is Tool 3 being a 1.3mm bit.
Once again all help and comments are appreciated (apart from abuse and violence !)
