Tetralite
Yeah, I am getting this, I got the file of the prop to imported fairly well, but it looks like that file had some problems.
Can you send me one of your files so I can play with it, the dime one would be cool.
Have you decieded on a price?

Thanks

What format does mach 3 store the file as?
Artcam pro wants an ASCII G-Code toolpath format.
Is it compatible?
Thanks

I am looking at buying  probe for use with mach 3. Does the probe only need a single contact?
Thanks

How does a servo drive that is 2 wire know what direction and speed?
I have been reading the yaskawa manual and the speed input terminals description says:
2. is at SG 0V. The rated forward ratation is given at +/- 6V.

Does this mean that 0V to -6V is 0-100% speed one direction and 0V to +6V is 0-100% speed the other direction?
I would just hook it up and play with it but I really dont want to let the smoke out of the boards on my new mill.
Thanks

I thought Mach 3 joged untill the switch cleared.
If your switch is bouncing it would probably cause this as other have stated.
Just my 2 cents.

Thanks,
I am familiar with stepper motors but my knowledge in servos is limited.
Can you explain how a servo drive works?
From reading the pixe datasheet, it looks like it wants a encoder input and the PID control lives in the pixe.
Does the servo drive only control the speed of the motors?
From looking at the yaskawa manual it has a tachometer input to the servo drive, So is the speed control closed loop also?
Also the speed reference input is 0 to +-6 for the yaskawa servopack, the output is jumper selectable on the pixe to -10 to 10 and -5 to 5, Are the voltages adjustable between these ranges?
Sorry for the million question.
Thanks for your help.

Hello,
Can someone give me some details on what a "pixie" is and how I can get one.
I have a Matsuura that has Yaskawa servo amps and I want to drive it with mach 3 and a breakout board.
Thanks for all your help.
