dspMC/IP Motion Controller / MPG - Hardware - Softlimit

« on: May 18, 2011, 04:20:14 PM »

 With DSPMC the problem is:
 MPG mode, Software Limits do not work, leaving the axes collide mechanically. Only in this situation.

 If someone can help me ..Thanks

G91 and other problems.

 Please I need help on some issues.

 I am using the latest versions of MACH3 XX.43.22 and some earlier and noticed the following.
 1. When we work on the G91 there is information that is not possible to stop and return the program REVERSE MODE.OK? Is it possible that someone's day?

 2. When in G91 and STOP program for cleaning up a torch or something and made ​​a command "RUN FRON HERE", the axes will move exactly twice the requested coordinates on the line where we start running. Seems to me that the versions of MACH2 did not.
 Is that correct?
 3. What can I do to my FEED HOLD or PAUSE is faster, ie, immediately stop the axes. I have a long delay until the axle stop.
 Attached the gcode I'm working on my Oxycorte.
 The deceleration of the axes are between 0.5 sec per axis.

 Such cases occur with either the SS or PP.

 With DSPMC the problem is:
 MPG mode, Software Limits do not work, leaving the axes collide mechanically. Only in this situation.

 If someone can help me ..Thanks

General Mach Discussion / Difference between STEP and DIR

« on: August 18, 2008, 08:29:01 PM »

I need help.
I am using the MACH3 3,041 in all reversals of direction (in any axis), but only for a sense (+), when the signal from the DIR has to go down, my servo motor account 1 pulse to the wrong side, then again from the right side, losing 2 pulses, which in my case = 0.002 by the pulse = 0.004mm in total.
When I turn the output STEP and DIR to perfect it, but the step can not pass a certain frequency, or at least when greater frequency, (high speed), my driver not to recognize.
I use Servo Drives Panasonic and a Bob C11G of CNC4PC - Duncan.
My driver has inputs with opto.
I already tried the following:
. Increase the time of "STEP" until 20us, not resolved, the system is held in high speeds.
. Increase the time of "DIR" until 20us  not resolved.
. Other versions of MACH3 until the "View 2.00", not resolved.
Please make any ideas for me?
I think the time reversal of direction is not large enough to make my driver a reversal. But a sense works, how it happens?
Is there any parameters possible to adjust the difference between Step and DIR?
What is the difference between the first "DIR" pulse and the first "STEP" You can adjust this parameter?
Thank you.
