auto level plate CTC prusa i3 SN04-N
thingiverse
I haven't found my happiness for an SN04-N sensor addition without spending 1 hour or 2 hours disassembling and reassembling. NEED : - 2 x M3 screws - 2 x M3x20 nuts (minimum) - 1 x SN04-N 10V-30V continuous sensor - 1 x printed support - 1 x 40k Ohm resistor ( /!\ without resistance you will burn your card !) HOW TO : - Install the sensor on the support - Clip the support behind the X carriage - The red wire is connected to the + of the FAN2 connector on the GT2560 board, the blue wire is connected to the - of the FAN2 connector on the GT2560 board, and the black wire with the resistor in series on the - Z mini connector. (You must therefore remove the endstop cable) Perform a functional test by passing a metal spatula for example. To modify the Marlin firmware, I leave you to search online, there are plenty of howtos. Otherwise, you will find a functional firmware for GT2560, marlin 1.0.2 with automatic leveling enabled here => https://blog.thesen.eu/prusa-geeetech-ix3-pro-gt2560-board-mit-autoleveling-nachruesten/ . This is the one I uploaded, it works perfectly.
