- Added a new bedlevel.gcode for people who need to level on a cold heatbed.

Ender 3 Neoteck Digital Dial Indicator Bracket
I have improved /thing:3148230 so that the dial indicator within it's bracket can be safely stored away (e.g. laying flat on a table) after usage. This wasn't possible before in the original design, because of the (topheavy) weight of the dial indicator making it always tilt down on one side.
I suggest to print this at 101% scale and the Neoteck digital dial indicator (8mm) slips perfectly into the bracket. However i have added a sticky point on the backside of the bracket (see pictures) so that it sits tight arround the fan shroud of the ender 3 (late 2018 Model). Printing at 100% size was a too tight fit for me, but your mileage may vary.
I have also added a bedlevel procedure (originated from Federico Salis) and improved it to support the Ender 3. Put the gcode on your SD card and follow these 10 steps:
- Start your printer and select the file "bedlevel procedure" from your SD card.
- The printer will auto home and heat up the heatbed to 60 degree celsius. Meanwhile, install and switch on your Neoteck dial indicator.
- After bed has reached 60 degree, press the button on your Ender 3 display.
- The nozzle will move into the first measure point at the front left corner of the heatbed. Use a piece of paper to manually set the nozzle height, but only with the bedlevel screw on the front left!
- Press the button again and the dial indicator probe will move onto the same spot you've just leveled. Now press the Zero button on the dial indicator! This front left corner is now your reference point (0.00mm).
- Press the (printer) button again and the dial indicator will move into every other corner and stop there, waiting for you to level each corner with it's corresponding bedlevel-screw, so that the dial indicator shows 0.00mm. After each point, press the (printer) button.
- The dial indicator will move into the center of the heatbed every now and then. Don't move any of the bedlevel screws here! This center measure is just for your information, so that you can get an idea of how much the heatbed is bent in the middle (i get values arround 0.05mm using a glass/mirror).
- After all measure points are done, the printhead will move into the front left corner again. Don't use the bedlevel screw here, it's just your reference point again, it should still be in the area of 0.00 - 0.01.
- Repeat the bedlevel procedure one more time, to make sure everything is fine.
- Your heatbed is leveled now as perfect as possible for your setup!
Neoteck digital dial indicator (0-25.4mm/1'') used for this thing:
Eryone 1,75mm PLA
Use support on buildplate only! (Cura: support placement = touching buildplate). No support needed for the 8.2mm hole which takes up the Neoteck dial indicator! I recommend printing this thing at 101% scale and use a soft sticky point (or piece of tape) on the inside of the bracket if needed, to make it fit tight arround the fan shroud (see pictures). This way you don't scratch your shroud or break something apart.
