EXTRUDER STOPPED WORKING

[Nishant 0]

hay guys i have printed 2-3 design its was good but suddenly my extruder stopped working there is no filament flow now the motor is stuck while printing , i have checked the motor by changing its pin to yaxis the motor works perfectly but while printing it gets stuck and stops the flow of filament.i have tried most of the troubleshoots and solution given on web but it didnt helped so it would be great if anyone would help me with this.

Is it grinding the filament or just not turning?

If the temp is 170 or below then it won't extrude.

Have you done any atomic pulls to make sure the nozzle is not blocked?

no its not grinding the filament & yeah i checked the nozzel its not block because when is push filament manually the filament comes out of the nozzel, & the temperature is set to 220 from my 1st print.

This is very common when a bit of fillament broke in the extruder motor causing a lot of friction. You should check if there is nothing stuck. You could take the block out.

there is no block or anything that stops the extruder, to check that i have operated the extruder by attaching it to the yaxis of the board and watched its movement the motor is completely working there are no issues.

i have also tried connecting the extruder at E2 the second connection for extruder still the same...it doesn't work!!

tried adding a new machine where the firmware is installed again but still the same, not working. any other solution for my problem?

I think your pcb may have burnt through. Try hooking it up on the x or y and look if it turns then. This way you can look if it is just the port or if it is your extruder motor
