    • Make sure none of the end stops are triggered.

    • Manually trigger the X end stop and re enter M119. It should return a status of "at min stop" for X and Y should say "not stopped"

    • Manually trigger the Y end stop and re enter M119. It should return a status of "at max stop" for Y and X should say "not stopped"

  2. J. Preflight Checklist-Endstops, BLTouch: step 2, image 1 of 1

    • You should have a Macros folder for your BLTouch. Select Deploy, the pin should deploy. Select Retract, the pin should retract.

    • If the BLTouch starts blinking at any point normally it's a bad connection check your wiring.

    • Occasionally running the "Alarm Release Pin Up" macro can solve a blinking BLTouch

    Edit

    • Heat the nozzle to 200c and bed to 60c and wait for the temperatures to stabilize. Remove any filament that is stuck to the nozzle.

    • If you have independent axis leveling configured make sure you run. Home all axis.

    • Jog the nozzle to the center of the bed. If using my github config, move the hotend X-40 so the nozzle is in the center of the bed.

    • Place a piece of paper under the nozzle.

    • A lot of times when calibrating Z offset the bed can't move up high enough because we don't have it configured to allow Z to go past 0. Out of habit when calibrating Z offset I will send G92 Z15 which tells the printer the new Z position is Z15. This will give me more than enough to calibrate the Z offset now.

    • In the console enter

    • M558 P9 C"^zprobe.in"

    • G31 P500 Z1.0

    Edit

    • Jog the bed up carefully using the Z-.50 and Z-.05 buttons until the nozzle grips the paper

    • Once the nozzle grips the paper send G92 Z0

    • Lower the bed 10mm

    • Move the probe to bed center(same amount as step 3 but move it to the right)

    • Send G30 S-1. This will probe the bed and tell you the offset. Move the bed to Z10 and run G30 S-1 again. Repeat this step a couple of times. When finished move the bed to Z10.

    • Take the average of the Z offset readings from the console and replace your current G31 P500 X-42.45 Y0 Z## in config.g

    • Save and restart your printer
