Smart Filament Sensor Mount for Tronxy XY-2 PRO TITAN Printer

thingiverse

This is a mount for the Big Tree Tech Smart Filament Sensor for the TRONXY XY-2 PRO TITAN printer. Simply remove the stock run-out sensor and mounting plate and remove the back from your sensor and mount this in it's place. You can use the screws from the removed mount to mount the plate to the printer. I print through Octoprint so this is wire directly to my Raspberry Pi running Octoprint and I use the Smart Filament Sensor plugin to pause the printer if no movement is detected. Since I only print from Octoprint, the stock run-out sensor is useless, so not having it doesn't prevent me from printing. I run the filament up into my printer enclosure from it's dry-box using a long piece of PTFE tubing. Seems to work quite well. The right side PTFE tube goes directly into the extruder after you remove the little plastic funnel piece that comes with your printer. TIP: One thing I have noted when trying to set up the sensor, on the exit side, I have to use a piece of PTFE tubing that is 4mm OD, 3mm ID. The opening of the normal 4mm OD, 2mm ID tubing is too small to allow the filament to pass when trying to feed it through the sensor. Once I switched to the larger tubing, all you have to do after inserting it is spin it and eventually the natural curve of the filament from being on the roll will allow it to pass right into the outlet.
