All,
I'm writing to solicit opinions on "coupled" motion such as driving the X-axis of a gantry router from both sides of the table. Which of the following is better?
Option A: "Mechanical" coupling (example: both sides of a gantry driven by a rack and pinion system actuated by a single servo/stepper motor via belts/gears/shafts)
Option B: "Electrical" coupling (example: each side of a gantry driven by twin servos/steppers but synced together via control software, with or without closed loop feedback)
Followup question: Which common control software (Mach3, EMC/LinuxCNC, Flashcut, etc.) is better at Option B?
Thanks for your thoughtful comments,
Tom
