The tube going from the filament sensor to the extruder... the original tubing specification is mediocre. Replace it with Capricorn tubing (link posted above). The Capricorn tubing is slicker. You can feel the difference when feeding filament to the extruder. This mod will help when you print with TPU filament.

Over the course of a month one of my R2's started having problems with the z axis repeatability resulting in many unusable parts. Then the z axis switch died. I replace the z axis sensor ( a real pain in the butt ) and while I was at it I removed the 10uf electrolytic cap on the IR board and replaced it with a much lower impedance stacked ceramic 1uf cap.

The result was I...

There is about 3% RH and 3C hysteresis in the system because if it's mass.

This stops wasted energy the heater is only on when the RH% is high and the temp low. It is set and forget, not requiring the constant pushing of buttons to keep the heater energized.

When I set for 15%RH the heater...

Filament Dryer (Sunlu Dryer Update)]]> Tue, 07 Sep 2021 22:35:06 +0000 http://community.robo3d.com/index.php?threads/bltouch-installation.24492/ http://community.robo3d.com/index.php?threads/bltouch-installation.24492/ invalid@example.com (Storm) Storm first of all, i hope this question has not been asked before.

I want to install a BLTouch sensor for my printer. My problem is, that i can't identify the proper pins to connect it to. I have connected all cables and the sensor is getting recognized, i can't reach it with any M-commands though.

Since there is no documentation on the location of the pin numbers, i can't connect the cables to the pins specified in the arduino code.

Has anyone of you installed a similiar sensor yet?...
