Issue with DvD drive stepper motor for 3d printer
April 01, 2021 09:07AM
Short version:

1: Is it possible to run just the stepper motors (pulled out of a DVD Drive) using either a 5v 2a mobile charger or a 9v battery plugged into the Ramps 1.6 power input?

2: what could be a possible issue for "echo: busy: processing" message on pronterface. I believe its not an issue with the extruder or bed temp reading.

Long version:

A year ago I tried building a 3dprinter using some DVD stepper motors. I was using two stepper motors, two a4988 stepper motor drivers, ramps 1.6, and Arduino mega. I didn't get anything else since I was not sure if I will be able to make a functional printer properly and didn't want to pointlessly invest in the hardware. For power, I was using a power bank with 2A 5V output. The steppers were working fine as expected. I kinda dumped the project since i got an ender 3.

Recently I decided to get back to it just for fun, tho this time I was using a different power source. It was a power adapter to charge cellphones and it had the same output. However this time none of the stepper motors moved. I tried everything, i kept getting "echo:busy: processing" on pronterface every time I tried to move an axis.

Im assuming the steppers could be busted but i don't have a lot of ways to test it.

So my questions are

1: Can i use a 9v battery to test out just the x and y axis or do i need a 12v smps?
2: can anyone explain wat could be the possible issue for echo message. I've tried to add/remove jumper wires to the extruder and bed temp pins (t0,t1 pins), so I'm assuming this cant be the issue.
3: If anyone has ever made a 3d printer using similar stuff, can u share your experience, and wat challenges u faced

also, sorry for sounding insanely dumb, and asking such trivial questions instead of trying them out. I'm an absolute beginner with arduinos and i live in the middle of nowhere so amazon is my only friend when i need something, better to ask here instead of waiting for a week for a mere battery smiling smiley Thanks

hi,

dvd steppers are no use for 3DP axis drive ,they may be ok for light weight pen plotters but nowhere near good enough for a printer. "didn't want to pointlessly invest in the hardware" a good set of nema 17 never considered pointless.aint sure about the echo message but you checked the baurd rates the same between software and and hardware.
