Change Filament Glitch

Hi,

I'm looking for some help troubleshooting an issue. My gigabot seems to be stuck in the "change filament" sequence because after the filament is changed (it heats up, retracts, insert filament, then extrude,then done), it goes to the home position and then restarts the change filament sequence all over again. The same glitch happens when I initiate any print file from the sd card. After heating the bed and heating the nozzle, instead of starting the print, it jumps into "change filament" mode. I It doesn't seem to want to do anything else, even after rebooting the gigabot. Any idea what might be going on or how it can be fixed?

I might add that periodically the y-motor runs away in the positive direction until it hits the rail. I usually jump up and flip the switch to the off position before it hits the rail. This occasionally happens right after the change filament sequence is complete which makes me think it is related to the other problem.

Thanks,

Daniel Calderon

Hi Daniel,

The change filament script is meant to kick in when A. the hot end heater turns on and B. there is no filament in the filament detector.

Are you sure that your filament is going into the corresponding filament detector switch at the beginning of the filament tube? If you are using the left extruder, you must make sure the filament is going into the left tube.

Are you using 3mm filament?

If the answer is yes to both of these, lets pull off the cover from the filament detector and make sure that the filament is tripping the switch properly. We can remove the 2 wires and stick them together to simulate a closed switch. Does the script go away when you do this?

Hi Mike,

The filament detector was it. I readjusted the screws on the switch and that fixed it.

Thanks

Daniel
