I didn't expect to be back so soon but here we are.
I was working on our machine today changing the wiring for the THC to true RAW voltage as I was still experiencing an issue where the Z axis would just rise off into space. After everything I had done during my last post I figured it was the only left.
Anyway I got it all put back together and was connecting my cables to the controller. I noticed that the x axis cable was in a bad spot so I unplugged it and moved it and then I made the mistake and it was HUGE. I didn’t realize that I hadn’t shut off the control box and when I plugged in the x axis cable it immediately started to smoke. I unplugged it as quickly as I could but the damage was already done. As of now I have a non working x axis and I bare minimum torched the Stepper motor pins.
So my questions are: Where can I source replacement parts?
Like I said bare minimum I need a new x axis stepper as the plug and cable is one piece.
How do I test to make sure there is no more damage done than just to the motor?
If you look close you can see the second pin from the bottom in the right row is now much shorter.
Been there, done that. (Not on LS system, but similar configuraiton) Stepper motor connector not plugged in all the way or tied down. Pzzzzzt! Gone. Funny how the connector pins melt the connector block. And that smell! Unique in all the Universe!
DB9 connections are available on Amazon or Google. If you can solder, there are only four wires. I bet the stepper is still functioning. You probably need to replace both sides of that connection.
If you’ve got a multimeter (even a cheap one), you probe for resistance.
You’ll touch the probe on the pin in the plug, and you’ll probe the wire end that’s left cut off (they should have individual colors, might have a stripe on them).
So when you touch say, pin 1, then you probe the blue wire (which, let’s pretend it’s the red wire), you’ll get no audible alert (depending on the multimeter you have) or it will show open loop/inifinity on the display.
But when you probe that same pin 1, and then probe the red wire, it may beep or show 0 ohms of resistance meaning, you found the wire that corresponds with that pin.
I don’t have the pinout, but as I mentioned, there are just four wires.
This is the standard color code for a nema 23.
This motor has a step angle of 1.8 deg., this means that it has 200 steps per revolution and for every step it will cover 1.8°. The motor has four color coded wires (Black, Green, Red & Blue) terminated with bare leads. Black and Green wire is connected with one coil; Red and Blue is connected with other.
