So something really bad happend...

Hello Mike,
I got the replacement parts, and I only replaced the control board(why rewire, when it just plugs in).
I uploaded the software to the board, and...
The problem went away, each axis is moving separately.
But the X axis is going the wrong way. It's not going the direction of the limit switch.
What do I do to reverse the x axis?

 

Unplug the x-axis connector from the board, flip it 180 degree around, and then plug it on the board.

 

Thanks, that worked.
But the E axis doesn't work, I had it working for a short time last night. But now nothing.

 

Please provide more details about your extruder problem.

 

Ugh, ok I have tried each procedure Mike had me go though for the Z axis issue.
Plug unplug, swap driver board, adjust pot, the axis is non responsive.

 

So you are having the z axis auto leveling issue, not the extruder/hotend issue then?

I don't have auto bed leveling feature on my printer so I'm not much of help in this area. I suspect that you can play around with changing the z offset until you get a good first layer.

Please confirm your exact problem so other experienced users can help you with that.

You're almost there, just hang in there.

 

Please read the thread, I solved the z axis issue by replacing the control board, like I said in post #41.
Then the e axis issue showed up.
This machine is turning out to be a great deal of frustration.

 

So what is the problem with your extruder? Please provide more details of what the problem is.

Extruder motor not working, filament jam/clog, etc...

 

I thought I did. Motor not working.

 

Ok. You probably have tried this already.

You may want to try plugging your extruder motor connector into x or y axis motor connection on the board to see whether the motor moves or not. You may want to take out the filament while testing this.

 

Yep motor is fine. Ever since my problems started, I haven't had any filament in the machine.
These problems are beyond my experience. I think I'm going to return the machine, for repair or replacement.

 

Understand your frustrations. You need to provide more details about your problem so we can help you.

You said that the motor was not working earlier, but now the motor is fine. So the problem is likely something else.

It could be the hobbed bolt, hotend filament jam, filament diameters not meeting the spec, etc... We need to sort out and narrow down the root cause of the problem.

So the extruder motor works. Next logical questions are: Can the hotend heat up? Can it feed the filament?

 

Mark, he had x, y, z axis working before except that the x axis was going wrong direction. He flipped the x axis connector and the x-axis is moving in the correction directions now. He also said that auto bed leveling is working since he replaced the controller board.

So that leaves the extruder motor. He confirmed that the extruder motor is working, so the problem is non motor issue. It could be the stepper driver board, hotend, hobbed bolt, or filament issue.

 

Nope, I haven't disassembled the extruder.
I tested the extruder motor on another drive/axis. It works, there is no interference.
Just to try something, I put the original driver board back in. Updated it's software, and the same issue is still present.
I swapped the driver board, nothing, adjust the driverboard pot. Not even a bump from the motor(when telling it to run(100m)).
So it's not the driver board, any suggestions, I'm feeling like I'm getting somewhere.

 

Ok. Just want to double confirm.

Is your extruder connector connecting to E0 on the board? E0 is where the extruder should connect to. E1 is for the 2nd extruder which most of us don't have unless you mod it yourself.

 

Yes it is on Eo.

 

Ah..., interesting. This is kind of strange. Now, let's try different thing.

Can you connect your x-axis motor to the E0 connector instead and try to see if you can send the command to move the motor?

Make sure you don't move too much so your x-axis motor does not bump into anything.

 

No response when plugging the x axis into Eo.

But I do get a response from the extruder motor when it's plugged into the x axis.
