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?
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.
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?
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!

You are smart! This is cool I want to set one of these up also and convert my mill to closed loop
Great Lesson from a great Maker & young Teacher ! Thank you very much !

Man, I love LinuxCNC!
Nice video, thanks for share, there is possible if i do use another type of motors? like motor from glass car, or a motor the fan the radiator?
thousand thanks! great explaination.
What PC are you exactly using so you're getting such a low latency numbers?
0:39 not in space, but how much it has turned ;) (moved in space would be at least 3 axis)
You're right! and its not just there where I mess up with my words, I sometimes say "power" when i mean "voltage" but I'm aware of that!

Hello there, can I control dc motor with encoder by 2 line the first one is pulses for steps and the second one is (0,1)for direction?

How did you find a main board with a parallel port these days ?
Scrap yards
Genius...
any updates ?

@@SciCynicalInventing this is awesome man, I can't wait to watch it and apply it.
Thanks man
How to download CNC softwer
You just have to download the linuxCNC .ISO file and put it on a usb with a program like rufus so you can boot from it.
