Topic: filawinder losing auto settings
After successfully demonstrating my filawinder and filastruder at my makerspace, I packed them up and brought them home. The next day the filawinder would not function. I removed the nano from the filawinder board and found that it would not even accept and run the standard blink sketch. I suspected damage from a static discharge so put aside the original nano and bought a replacement.
I uploaded the v9a firmware to the new nano and everything seemed great so I began to extrude and wind. The filawinder quit auto winding after a few minutes. This happened a few times before I gave up.
Further testing in troubleshooting mode shows what seem to be reasonable values for everything and auto mode begins and seems normal with lowering filament speeding up the motor, etc. However, if the filament is moved up and down by hand fairly rapidly, it is possible to cause the yellow pin 13 LED on the arduino to flash, the filament guide arm jerks a bit, the serial port readout shows one or two gibberish characters and the automatic winding stops. This happens more easily with the troubleshooting jumper on. I am not sure, but it may happen more often when the magnet is near the hall sensor.
Most times it is possible to just set the switch to manual mode, push the middle button, and wave filament to set the sensors and it will be back in auto mode. Once in awhile when the auto mode quits, the arduino seems to be locked up and nothing short of a complete reboot or a reset will allow any function.
Has anyone seen any similar malfunctions?
