I just messed up with the wires of the extruder stepper. Now it wobbles instead of loading or unloading filament. I tried all the combinations but seems it won’t change. It “pulse” or it wobbles bit it won’t move the filament.
thoughs? (Aside the fact that i’m a mess?)

@Andre_Russo, what printer do you have?
What printer and what exactly do you mean by messed up the wires? Did you move them or cut them up trying to fix something?
Got a ctc and it was working good. Then i took out their connector the 4 wires on top of the motor popped out and now it won’t work and i think i’ve tried all the possible combinations
So you are pretty sure you have the right cable going back to the motor? Is it by chance that the you are plugging it in backwards? Not so easy to do but possible.
You can look at the main board and the connectors should be labeled enough to tell you what cable goes to which motor.

I’m sure it is plugged correctly to the motherboard. Red black blue and green wires on the top of the extruder just never make the motor spin constantly one way or the other. Just wobbling or making noise w/o moving. I tried a different motor and it does the same. Tried the motor to the y axis motor connector and it works properly. I don’t know what to do
Cable is bad then. Try a different cable. Or the stepper driver is bad which is on the board. You may be able to swap it out with a different one to see if it fixes it.
I thought it could be the driver. I will try the cable first and then see about the driver. Many thanks.
Looks like i just burnt 2 stepper drivers.
I got another question if i may. How can i make the motor change it’s movement? I mean how can i make it turn clockwise when i want to load filament instead of its standart anti-clockwise?
There should be some kind of a filament load / unload from the control panel on the printer.
Hahahaha. Of course. What i meant is if there’s any chance i can make it load on the other side. It was a dual now single extruder and i need to make it spin the other eay around
The stepper motor is simply going to do what it is told depending on where it is plugged in. The motor is simply that - a motor. It spins in the direction it is told. If plugged into the left extruder cable it will respond accordingly, likewise when plugged into the right extruder cable it will respond to those signals. All the stepper motors on the printer are the same.
Cool. The only fact is that if i use the printer as single extruder, it have to be the right one. And it loads spinning anti-clockwise. How can i reverse this to make the machine loading while the motor is spinning clockwise?
It has nothing to do with the motor. If you are using the correct cable for the right side (it is plugged into the port for the right extruder on the board) then my guess is you have also left the other parts on the motor when moving it.
The motor is the only part really that can go on either side. The other parts that bolt to it have a right and left.
Yes. You’re right. Not really answering tho, since the printer won’t work with extruder n.2(left) only. Anyway thanks a lot. Much appreciated
You’ll need to post a pic of the setup then because I guess I am not understanding. The motor has no left or right. The direction the motor spins is controlled by the board. If you were to plug the cable for the left extruder into the right extruder then it is going to spin the opposite direction.
The other plastic parts that are the extruder feed do have a left and right.
Why does it have to be the right one?

Andre,
I think what you are trying to say is that you want to use your left extruder on the right, while having it plugged into the left extruder driver on the mainboard. This will indeed result in the stepper motor going in the opposite direction than you want it to.
You cant really fix this without recompling the firmware, so no, you dont want to do that.
I assume you are looking to print while you are awaiting parts for repair.
I also understand your statement that if you are printing with only one extruder attached to your printer, that it has to be the right one. This is mostly true, as the right motor needs to be there for the end stop to hit it.
I dont know what slicer software you are using. But you should be able to specify left or right extruder in your software, and print from the left extruder with the right extruder attached but unplugged.
You can change the feed direction in firmware with ReplicatorG:
go to device settings, motherboard tab. Play with the invert a axis / invert b axis checkboxes.
Yes Perry. The printer is running with just one extruder, ext n.2 or “the left one” has been unplugged and removed. Therefore the machine itself it can’t work with other extruder than the n.1( or the right) i guess for the reason you mentioned about hotting the end stop. Anyway, this one is loading anticlockwise and i need to make it load the other way around. Any idea on how can i do that?
