If you have proper EXCELLON drillfile format cut and paste that code in
left column, after that see to it that you have correct input parameters
for the EXCELLON file and then GENERATE G-CODE.
There are NO C chars in the generated G-code

I should have mentioned the beam axle was installed in 1849, not sure
if the bearing bronzes have ever been replaced on the beam axle. In my

Don't over look grease also. Pressurized oil is probably the best,
however a lot of machines simply have zerk fittings to grease slides.
I think a lot of that depends on the speed that the bearing operates at.

oil should be oozing out from slideways, if not old oil can be clogged
