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 It features two different height sized BLT height blocks for various types of nozzles. Use the 5mm block for standard 5mm brass nozzles and the 10mm block for extra large sized ones. You will need to download the left bracket part from here: http://www.thingiverse.com/thing:1925459, along with 2 x M2 20mm bolts & 2 x M2 nuts for mounting the BLTouch. Additionally, you will require the latest version of Arduino IDE (1.1.6.8): www.arduino.cc. Instructions from Grogo666 are as follows: Upload firmware to Reach3D using the Arduino app. Connect a USB cable to the printer and a slicer such as Simplify3D, MatterControl, or Cura. In the slicer terminal, run the following commands: M280 P0 S10 (to raise BLT pin) M280 P0 S90 (to drop BLT pin) M280 P0 S120 enters in test mode (up/down). Perform M402 to stop it. If BLT enters error mode (blinking red), issue a M280 P0 S160 to shut the alarm off. Perform a G28, which should probe the center of the bed twice at full speed and then slow speed. Then do G1 Z0 - position won't be good so you need to correct the Z-Offset. Do an M851 command; it should return the Z OFFSET. Move BED Y-35 & X -10 to put the nozzle where the BLTouch just probed. Place a sheet of paper under the nozzle and level as desired, going down progressively in 0.1 steps. 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 at the correct height for you, issue: M851 Z-xx.xx where xx.xx is the distance you noted Immediately issue M500 to store it in EEPROM. Do a M851 or M501; you should see the value you entered for Z-Offset. Perform a G28 and then a G29, which will probe 9 points on your bed. Now you are ready to print with the BLTouch!
