I found this setup/discovery so brilliant, but it has limitation that motor brushes gets clogged soon and its pain to maintain... Is it possible to hook encoders with stepper motors?
Hi, may I ask for an advice: i have stepper motor from dvd rom. It has 4 wires, meaning I could connect only 2 motors (via L298n) to control via parallel port. However, I seen youtube videos on using in-build floppy drivers in which case you need only 2 parallel port pins.. is there a way to set up motor so (2 wires in port) using L298n controller?
You know you could probably just use two optocouplers acting as AND gate, right? Direction signals into diodes and PWM signal to collectors -> one of emmiters should give you PWM depending on direction.
movement in space is relative to 4 dimensions, X/Y/Z/T (TIME). time is always moving, so moving any other axis would be relocating something in a space movement. Jus sayin.
Sorry for the late reply, I actually built 2 drawing robots based on stepper motors a little before this video was made and after this video got uploaded I ordered the appropriate DC encoder controller chips that the configuration in LinuxCNC used. The next video following this one will be making a drawing robot based on DC encoders!
