@griff “AS” to positive as well sir.
The max speeds and feeds on the TAS will largely depend on your machine and setup ridgidity. I run close to 2000sfm on 1/4 and 2300sfm on 3/8s with microdrop ensuring lubrication and heat management. Usually run a minimum of ipm of 150-175 and 1.7-2.4 on the modded s3. Manufacturer recommends a 3 thou chip but we cant go that hard lol.
On a stock s3 I’ll keep it at 75ish ipm and 1.3-1.7 thou chipload to keep chatter under control.
@WillAdams imo it would be more effective adding a 5th bearing support to counteract leverage. I know I’ve had quite a bit of luck with that method. Thinking about trying a different style linear rail.
Im trying to get an electrician in here today to measure voltage and amp draw.
