Gcode for beddleveling any4max（河床平整代碼）

Two simple, adjustable and short procedures in Gcode for manual bedleveling. Setting the bed is annoying enough, this makes it all a little bit easier I hope.
The codes do not print anything, only intended to adjust the bed. Start a code the same as you start a print.
Initially written for my Tevo Tornado. But the Gcode is adjusted for the Anycubic 4MAX. It is most probably also suitable for the Ender 3 and clones without touchscreen. Just check the short and easy to undetand Gcode.
The Gcode files contain two patter for leveling (see pictures). In a rectangle (square), and across the diagonals (radial). I use the last one for finetuning my printbed.
The codes preheats the bed and the nozzle (50 and 200 Celsius) before the adjusting-procedure begi. If you don't want to wait for preheating, disable line 7,8 and 9.
The Gcode jumps from point to point, and pauses in between for adjusting. Press the knob for the next point.
FL in the screenmessages stand for Front Left, FR for Front Right, RR for Rear right and RL for Rear Left.
Of coue the use of these codes is entirely at your own risk. Check carefully that your bed is free and has enough space to move.
Do not use the stl, it is there to satisfy thingivee.
Happy bedleveling :)
