Fact is, many 3D printers, including some very high quality machines, still do not have automatic bed leveling systems built into them. However, thanks to one man named Charles Lee, this may all be about to change for the better. Tomorrow, September 1, 2015, the BLTouch will be unveiled as part of an Indiegogo crowdfunding campaign. The BLTouch is an auto leveling sensor for 3D printers, and the best part is that it can be added onto almost any FDM/FFF 3D printer available today.
“BLTouch is an auto leveling sensor for 3D Printers based on open-source,” Charles Lee tells 3DPrint.com. “It could work with any kind of bed materials, such as glasses, woods, metals, and so on. BLTouch consists of Atmel ATtiny13A, solenoid, and a push pin. We have several patents and some are patent pending, and we have already completed the patent application for this project. “
“You can connect BLTouch with an existing servo motor connector(3 pin) and Zmin connector(2 pin),” Lee explains. “If your 3D printer does not have the auto leveling function, then you should have it updated, and add the two connectors which are enclosed [with our product]. In this process, soldering might be needed.”
Like mentioned above, the Indiegogo campaign is slated to launch tomorrow. The BLTouch will be available for $29, with a special early bird price of $25. If all goes as planned, production will begin in mid September, with shipping of the product to backers starting in mid October. International shipping will cost an additional $5.00 and the product will be shipped worldwide.
