Topic: Extruder motor acting strange....

good evening all...

Not sure what is going on with my extruder motor.
It seemed liked it was skipping... and was not extruding
correctly... I checked to make sure it was not a clog...
I then disassembled the extruder removing just the motor and
again ran the extruder motor....

Even out of the housing it is doing it... skipping back and forth
instead of running nice and steady....  not sure what the
deal is with it...

Anyone have this issue before?

And yes... I did shutdown... and completely cold boot back up...
and still have same issue...

Anyone???????????

Re: Extruder motor acting strange....

the thing is this....

1.  I can home all of the other axis and they appear to be working correctly.
2.  I have the extruder motor detached from the hot end...
3.  I have the hotend up to temp (so I can try to extrude with the motor)

Extruder motor does not turn as normal... but kinda jerks back and forth.
It acts as if it is stuck or something...  there is nothing to hinder it from turning
while it is detached....

any guesses as to what might be going on?

Re: Extruder motor acting strange....

When the printer is powered down can you rotate the motor shaft or is it bound up?

Ward...

I can rotate the motor... it does have a slight bit of tension (I assume the motor bearings inside)
but the shaft will turn....

I'm going to be away for about an hour but I will get back to you.  Try plugging in one of the other motors (switch the plugs on the board) you need to figure out if it is the motor or the driver that is causing this.  Don't power up the board with out a motor plugged in though.

Re: Extruder motor acting strange....

Ok....

check this....

I tried what you said... and hooked the extruder motor to Z axis and it worked just fine....
I connected it back to extruder and used code M302 so I could cold extrude and it acted wonky....
and then the Z axis started acting weird....

NOW I have been using Simplify3D

So I thought... would it do the same thing in Repetier Host?

I disconnected from Simplify3D and connected with Repetier... AND.....

Everything worked fine.... WTH???????

so disconnected from Repetier and went back to Simplify3D....

and everything works fine now.... WTH????

What a weird series of events... and I am still not sure what happened....

Hmmmm... If it's not broke don't fix it? I guess you'll have to wait for it to act up again.
