Oh, OK, I see. I know what you mean to an extent, I don't have a lathe yet  . I work at a pretty large plant with 9 large twin spindle Okumas V55 and larger and 3 twin doosans, same size. They don't see the need for a cam package. I do and the programmer certainly does, but they make the rules. I hope Lazycam will mature to what you want. I know those guys are busy as bees right now. I have no idea the cost, but feature cam looks pretty good for lathes. I wish I could say Lazycam will be done soon, but I don't know. They have a lot of irons in the fire right now.

Some day I should have a look at the fanuc style turn cycles.... They are a real pain in the butt and I can't see getting to it anytime soon ;(

I do have most of the code that I need from Lcam.... Hmmm....  if there were time that is all we need now!

Dear friends,
I'm new in the discussion. I write from Italy and I use Mach3 version R.1.83.
I have a strange problem using slow feed rate (actually >50 and <150 mm/min).
I was afraid of high feed rate but then problem is on the contrary.
As "destructive test", I've tested my machine at 1500 mm/min with hard acceleration, jogging and working and everything is OK! No missing steps.
As I feed at 100 mm/min then motors begin jerking very evidently (even vibrating forward and backward for a while)
I have tried everything:
new powerfull power supply, shielded cables, new computer (but the computer are PIII 650/1000 WIN 2000 newly installed, driver test really shows picks higher than the suggested), new printer cable, every possible suggestion found in the forum (backslash, slow acceleration, pulse width, I suspected even wrong GCode) but nothing.
Same problems even with the newest limited version of Mach3 downloadable from the site...
Any suggestion?
Many thanks in advance

Antonio
