my extruder was randomly turning off during the print, no it turns off as soon as i hit print. It extrudes fine before printing with manual controls. I lowered the bed so there is no resistance and it does not help. Any suggestions?
used both repetier and simplify. same issue on both
been printing with this thing for over a year, upgrading parts along the way so this is an all of a sudden problem.
azteeg x3 pro board on a solidoodle 3. e3d v5 hotend, direct drive extruder
i rewired the extruder motor thinking that was the issue, no dice
plenty of torque when using manual extrude
Have you looked at the gcode?
No, but I generated code from two different slicers on multiple parts, so pretty sure that isn’t it
I have had this happen a couple of times. In my case it turned out to be broken motor wires. I know you said you rewired the motor, but did you rewire it all the way into the motor housing? The stranded wires where the motor moves on the axis tend to bread if they are not secured just right. The way I tested for it was to tell it to extrude 100mm (no filament in drive) with Pronterface and then bent the wires by hand up and down where they move. Sure enough right at the motor when I twisted the motor wires it would quit extruding.
Thanks guys I’ll test more in a bit
I have had this happen before also. For what ever reason i had to up the current slightly. Don’t know what it would change other that maybe the rods needed lubed so as to roll smoother.
just tried to retract and all it did was oscillate
it was plenty hot
got it to move by wiggling the wires at the motor. definitely a bad connection inside
If you’re handy with the soldering iron and tight spaces, then you can open up the back of the motor and expose the wires as far in as practical to run new wires. Don’t use the old ones. After that it is a good idea to loop a length of the wires and secure it so that if they break again it won’t happen right at the motor housing and you will have a decent length to work with.
Or just replace the motor. I plan on the next motors I get having the molex type connector on the housing to eliminate the possibility of the wires breaking close to the windings.
In my case, the switching power supply shut downs everytime the hot end or heat bed turned on. Turns out the 12V 20A power supply need to be replaced.
Motor replaced, seemed to work until this new error halted things. http://i.imgur.com/kQEfwKj.jpg
What firmware are you using on the Azteeg? That looks similar to an error I had with the thermal runaway protection problem I had before calibrating the PID settings with Marlin. If it is a temp issue, you’re going to need to double check all of your heater wiring.
I’m unfamiliar with anything other than Marlin/Sprinter and the fact that there is no specific error code makes it a little difficult. If you are using the stock firmware then you may need to check the solidoodle forums.
A quick google search of “solidoodle printer stopped due to errors” comes up with lots of heater problems, so that may be the best place to start looking.
Marlin, custom, not solidoodles. I think you are right about the heater. I’ll check the wires for the hot end and thermister tonight
Ran new wires for the heater, and fixed one of the wire breaks on the thermister. Printed fine last night but the other thermister wire must have a break because it kept dropping the temp reading this morning. I may switch to the thermocouple again for durability.
Glad to hear you are figuring it out. I recently spent 2 weeks chasing the banding gremlin, still never really got it completely fixed but it’s much better now. Ended up doing a major overhaul in the process.
