Hi, After lot of struggling to cnc machine a board designed in Eagle, finally succeeded with a test board (many thanks to all forums on the internet).
Now switching to a board I am going to use, which has 7 of LM7809 to supply power for hobby servo motors, I'm faced with the problem of having vias' and parts and holes in different drill sizes.
If I attach a drill bit of my vias' size - which is 0.6mm - and load the g-code file to Mach3, it will attempt to drill all, i.e. vias, components' pads, holes and will break the drill bit of 0.6mm.
I need to be able to get either of these done: 1. Some how command eagle to make all vias and pads etc. drill sizes equal (to 1mm I need) before auto-routing (I have ground plane defined too), or 2. Get separate g-code file for separate drilling layers (like for vias, pads, holes), but I didn't find an option so that I could choose g-code related to a layer (in pcb-gcode ulp).
Could anyone help with some ideas what better/easier to do please?
