Tweaking a Fadal
I have 2 Fadals. One 60 by 30 with box ways, and one 40 by 20 with linear ways(boxZ). Both still have the original cnc88hs control, with hs "jokingly" referring to high speed.
These machines were considered high speed in their day, but not now, by any stretch.
If anyone has any input on how to tweak these machines to get the fastest and most accurate cutting feedrate out of them with whatever M and G codes are available, please let me know.
I have been pretty much using them at feedrates of about 70-80ipm for finishing using M91 and no G8 or G9 programmed in. (However, I believe G8 is a default at startup anyway). I just don't like the banging resulting from the use of M92, and my service rep says it's better without it due to the stress to the bearing mounts.
