Yet another cheap build - Need your help!
Posted: Fri Jul 10, 2015 1:30 pm
Hi guys.
I'm looking to start my own build but being that I have some questions that are CDROM related I thought that I'd post them here.
I found an old DVD/RW drive I had sitting around (TDK 420N) and thought it could be a good host for my fist SLA trials. I've sourced some DRV8825 Drivers really cheaply and got a 3000 Lumen DLP Projector for very cheap so I think I'm off to a good start.
The drive sled motor is a bit interesting and I'm wondering if anyone has thoughts or suggestions for me. The motor itself is in the first photo below. It says CL980U D2Z24A. I did try some google searching but didn't see any specs (at least nothing in English). Anyhow, the motor only has two leads +/- and I'll assume it takes 12V DC without issue.
Here's the interesting thing though. If you look at the photos that follow you'll notice that on the gear end of the motor I have some sort of optical sensor that I'm guessing looks for a Zero point in the motors travels. I've tried taking the clearest photos I can in the hopes that someone might know more about electronics that I do (actually I think 90%+ of you likely do).
The white wire lead had 5 pins. Pins 1 & 2 def go to the motor directly but I'm not sure what 3,4,5 do.
Any thoughts for me? I suppose that I could ignore them and manually figure out my stops but being that its there for me to use I thought I'd inquire.
One other question to show how naive I am...
Can anyone explain what the pinout I'd use are for the DRV8825 drivers? What goes to the Uno? What goes to the 12V stepper? do I also need a 12V power supply feed (and should I pick a PS smaller than 500mA/higher??)?
Thanks in advance.
