Check out this page. Read your way thought and you will get to a section that has the different gcode to set in estlcam for start, tool change and end. This will have you probing each time.

If you just want to see it work then go to the terminal and type G38.2 Z0. The LR3 will start going down until it hits the probe. If you are just hitting the button for home then its going to go up and hit the endstops. Because we home the machine this way we have to use G38.2 to do probing. The gcode on the milling basics page has that. Make sure you are on the lowrider tab when you get to that section, then copy and paste it into estlcam and make sure you save afterwords.

Your control board is controlled by a language called g-code. It is a simple, and human readable language. G-code can be delivered to the control board in a variety of ways:

  • It can be put in a file and read off the SD card.
  • It can be put in a file and read and sent by Repetier-Host.
  • It can be hand typed in the manual tab of Repetier-Host.
  • It can be attached to custom buttons in Repetier-Host.
  • It can be typed in using the console on the TFT
  • It can be automatically attached to the beginning of files in both Repetier-Host and EstlCam.
  • It can be triggered by a custom menu item in Marlin mode on your display.
  • And more.

The following is one g-code script designed to probe on the Lowerrider. Comments (text after the ‘;’) are optional and ignored:

G38.2 Z-20 F300 ; Probe downward and generate an error if -20 is reached
G92 Z0.5        ; Set Z to the thickness of the touch plate
G0 Z15 F300     ; Raise Z to 5 (must be greater than the thickness of the touch plate)

Note that the V1 touch plate is 0.5mm thick. You want to set this value to the thickness of your touch plate.

If you are using Repetier-Host, my suggestion is to first enter these three lines by hand a few times just to understand what they do, then attach them to one of Repetier-Host’s custom buttons. As some point, you may want to have them automatically added to the beginning of your scripts, but understanding how they fit in the process is valuable…and there may be times when you want to probe the spoilboard instead of the top of the stock.
