Reach3D BLTouch Setup Marlin 1.1.0 RC8

thingiverse

This is the latest version of Marlin 1.1.0 RC8 modified for the Reach3D printer http://www.reach3dprinters.com with two different height sized BLT height blocks for different kind of nozzles. Use the 5mm for standard 5mm brass nozzles and the 10mm for extra large sized ones. You will need to download the left bracket part from here and also have 2 x M2 20mm bolts & 2 x M2 nuts for mounting the BLTouch > http://www.thingiverse.com/thing:1925459 plus the latest version of Arduino IDE (1.1.6.8) > www.arduino.cc Instructions (from Grogo666): Upload firmware to Reach3D using Arduino app. Run USB cable to printer with slicer ie. Simplify3D, MatterControl, Cura etc. In slicer terminal run: M280 P0 S10 (to raise BLT pin) M280 P0 S90 (to drop BLT pin) M280 P0 S120 enters in test mode (up/down) Perfom M402 to stop it. If BLT enters error mode (blinking red) issue a M280 P0 S160 to shut alarm off. Do a G28 - should probe center of bed twice, full speed and then slow speed. Then do G1 Z0 - position won't be good so you need to correct Z-Offset. Do M851 command, should return Z OFFSET Move BED Y-35 & X -10 to put the nozzle where the BLTouch just probed. Get a sheet of paper under nozzle, and do 0.1 steps, and level as you wish going down progressivly, note the distance on your LCD screen. Software Endstop in FW has been deactivated so that the Z can actually have negative values. Once the nozzle is correct height for you, issue: M851 Z-xx.xx where xx.xx is the distance you noted Immediately issue M500 to store in EEPROM Do a M851 or M501 you should see the value you entered for Z-Offset Do a G28 Do a G29, it will probe 9 points on your bed. Now you are ready to print with the BLTouch!
