Envisioning a Cartesian machine with parallel axis with overlapping work areas.
Is there a way to prevent/predict crashes between these overlapping axis with
some sort of dynamic soft limit system?
For example X can travel from 0-100, and U can travel from 20-120, U can be
located in any positi

Might be a job for inihal pins ini.N.ini_limit and ini.
Are you going to have multiple tools working within the same work envelope
on the same piece?

That was the idea.

On
I can envision three scenarios that have to be considered from my very
limited experience.
Scenario 1 - Fixed timing - When tools are set up relative timing of the
operations do not vary. Throughout the run of the program, the operations
will be in a coordinated dance that will be known up front
Can serport be used to supply +-10 v pwm for servo drive control? Is the
voltage output controllable? Wiki says 232 voltage can be +-13 or +- 24 so
I think voltage could be an issue.
I got the serport docs here ,
http://www.linuxcnc.org/docs/html/man/man9/serport.9.html
Is there anything else I nee
No, That is not going to work. PWM is where to send a square wave but
very the duty cycle of the wave is resolution of at least one part in 256
or better to one part in 1024.
If for some reason all you had was a serial port them you build a little
device using say, maybe an Arduino-nano that re

Gene, just expanded to dual par ports, and am eliminating optos from my
stepper drives with a direct via db25 Bob . My drive is +-10 and I do have
a Chinese opto'd bob that has a pwm , but it is not bi-directional . And I
don't really want to put a flip flop relay in the output , so I'm still
rathe

Usually it is used as an on/off signal and only duty cycle is important.
