The way they did the 3rd option Gcode was use a standard lathe CAM and draw the 2 paths on different layers and post them as 2 passes.  then he loads the Gcode in  Excell takes the second toolpass and copies  the profile axis column to a new column and moves it down to match the same offset amount as the 2 tools are offset.  He said that  a precise match up with both profiles is not essential as you are taking a rather large cut each time. Just get it close.

He also said the Cam manf wanted a small fortune to do a special post so this is what they use now.

The machines with auto loader run 24/7 only stopping for tool changes or  breaks down.

 Learn something new every day, (;-) TP 

IT's as easy as that and it could easily be made into a VB program in Excell...
ment to write something like this but then saw someone beat me to it ;-)

A little bit more fancy then?

How fancy can you get with a fan?

at least a bit more curvature...

Yep!  I didn't like it and plan to make another one.

A little bit more fancy then?

backlash is a bitch!

even when i'm machining ALU at a speed of 200 mm/min with a step depth of 5mm and a stepover of 0.5mm (10mm flatendmill) you will see a significant difference between the different steps you take...

anyway, will need to make a more solid machine to put the servos onto with ballscrews and the whole lot...

will try to put something together to keep the leadscrews from trashing themselves and the crossslide.

General Mach Discussion / Re: Question for anyone with 'enable/disable' capable servo drives

« on: March 18, 2010, 08:24:11 AM »

am i right if i say you talk about the communication between mach -3 and the servo controllers.

i think the original question is about the servo controller on its own, ie will the hard/software on the controller do anything if the encoders are changed during disable and the drive is then put back to enable. lets assume mach3 isn't connected at that moment so no extra pulses can be transmitted...

simpson please correct me if i'm wrong...
