PROBING SCRIPT shown in video:
For clarity and convenience, I'm using my Jackpot with hard limits enabled and soft limits enabled, and my table size included in my config.yaml file, and the following is the script I'm using for my Probe macro (except I have the M0 commands commented out by starting those lines with a semi-colon, and I also don't use the last line for spindle start):
G21 (MSG G21: Metric mode)
G90 (MSG G90: Switching to absolute positioning)
G94 (MSG G94: Feed = per minute)
G92 X0 Y0 (MSG G92: Setting current XY position as workspace origin 0,0)
M0 (MSG Attach probe)
G38.2 G91 Z-124.9 F400 (MSG G38.2: Fast probing to material)
G1 Z5 F400 (MSG G1 move Z up by 5mm, speed 400)
G38.2 G91 Z-6 F100 P0.34 (MSG G38.2: Slow probing to material. Plate thickness: 0.34)
G90 (MSG G90: Switching to absolute positioning)
G1 Z30 F900 (MSG G1: go to Z30, speed 900)
M0 (MSG Remove probe)
M62 P1 (If used start spindle pin27)
ALSO NOTE: For this video, for use of the "squaring" script, in my probing script, I have the "G92 X0 Y0" line commented out (starting it with a semicolon), and my "squaring" script is programmed to use the Machine's homed 0,0 origin. You can program yours to base on a workspace offset origin if you like, just be aware of how you're doing it.
Re. SQUARING SCRIPT:
V1E docs with full details for SQUARING: docs.v1e.com/l...
...which includes JAIME's TOOL for creating various scripts, including for drawing "L" with a pen in corners for checking for square: vector76.githu...
My script shown in the video did not come from there. See below.
(NOTE: I looked at Jaime’s script creation tool just now, and noticed that its “Squareness marks” feature seems to be focused on making pen marks (in “L” shape) instead of dropping the sharp V-bit to make a hole. I looked to see if another feature of the tool could do this, and did not seem to see anything. I may have missed it. So, editing my script may be something to try after all.)
; ( GCode Macro Script by Doug Joseph, 1/10/24, to check his full size LowRider table for squareness. )
; ( This script uses 4 XY points, 1 in each corner, to drop a sharp v-bit down into masking tape placed )
; ( ...at each corner, making holes for measuring the two diagonals. Ideally, the diagonals should match. )
; ( This script assumes homing has already happened, and that probing to touch plate on spoil board has already happened. )
; ( Doug's LowRider's max travels, aka table dimensions: )
; ( X /axes/x/max_travel_mm = 2470.000 )
; ( Y /axes/y/max_travel_mm = 1250.000 )
; ( Z /axes/z/max_travel_mm = 125.000 )
; ( The 4 XY points for marking the tape, of which the first can also be used for probing, are )
; ( Point 1: X , Y = 28.000 , 18.500 )
; ( Point 2: X , Y = 28.000 , 1230.0 )
; ( Point 3: X , Y = 2460.0 , 1230.0 )
; ( Point 4: X , Y = 2460.0 , 18.500 )

Thanks Doug!

Nice work i like your adjustable y endstop .

[@design8studio]

Yep, that's part of my "hidden belts" mod. www.printables.com/model/422468-lowrider-3-cnc-hidden-belts-mod-hideprotect-either I'm pretty sure Ryan's standard Y end stop can be adjusted too!
