Hi Mark, I'm attaching the ini file. It's definitely not perfect, but a replacement spindle arrived this week and the machine has been cutting at 20% faster rates than on the Philips due to the possibility of using feeds above 1500. The parts look good and I hope tool life will be better as well, since I replaced all the plunges with fancy entry strategies.
Previously, out of the 18000 rpm available on the little Elte spindle I was using around 14000 due to the feedrate cap. Now it's working at full speed, and feedrates have gone from 1500 to 1890 mm/min. In reality, the feeds in helical cuts are ca. 500, but my parts are mostly straight and the increased cutting speed is actually used most of the time.
I'm mentioning all this to let you know that I'm actually using this config and it works. So it's not a situation where I'm a backseat driver goading you into doing something risky. If the service tech I've been in contact with actually comes to inspect the mill I will ask him about the tuning and post his opinions as well. He is well acquainted with the subject. A retired machine tool electronics specialist whom I know and bothered over the phone on this subject suggested that I should find manuals for the Siemens Sinumerik 810 control online and try their method. I haven't tried that yet due to lack of time, but if the Philips has decent info on tuning but the gains are dervied instead of entered manually, chances are some other controller with a good manual could provide good targets to shoot for that can be more easily applied to LinuxCNC.
