Description
A redo of my Filament box with monitoring and auto pause if filament jams or breaks. That's the idea anyway. Getting the top off with the filament coming through it was like fighting an octopus. So MK2 it comes out the side through 4x2 Teflon tubing, passes through the counters and up to the printer.
The monitor has 4 states;
1: Just sitting doing nothing, all LED's on
2: Waiting for regular movement, Blue LED. About 15 seconds of movement. either feed.
3: Monitoring, Green LED. As long as it does not stop for 15 seconds, either feed.
4: Paused, RED LED and Pause connection held low. Also beeps.
Still a work in progress, the electronics will be stripboarded and boxed. Still need to connect it to the printer Pause connection. I think it can be powered from there also. some research needed. Using the old box.
The box lid needs some material removal so the clip clears the monitors to get the lid off.
Probably going to fit the push-fit connectors on the top outlet of the monitor.
Been working on the ESP8266 Micropython code, I was running into lack of RAM problems but after a good deal of googling I can now roll my own firmware with the code built in, saves a shed load of ram. I will post a .bin file when it is in a finished state. Just a case of flashing it to a suitable ESP8266 board at that point. Also changed the 3 led's to a single NeoPixel.
Added box parts for circuit boards. Also Fritzing circuit file and MicroPython ESP8266 firmware file for flashing. Python files that are baked into firmware.
Swapped back to Arduino code on the ESP8266 as the MicroPython code was unreliable.
