My Hictop Bed leveling setup

Post by Roberts_Clif » September 28th, 2017, 1:03 pm

After finding and enabling Bed Leveling + Save Bed leveling Data in Marlin 1.1.5, Bad prints have almost disappeared.

:: Would Preform this from time to time, can't hurt...
G28 ; Auto Home
G29 S ; Auto Bed Leveling + Save Data
My Bi-Linear Bed Data 3 x 3 matrix
< ----0--------1---------2
< 0 -0.123 +0.082 +0.095
< 1 -0.260 +0.002 +0.017
< 2 -0.025 -0.025 -0.160

Add the following to your slicer start up code
Restart 3D Printer

G28 ; Auto Home
M420 S1 ; Enable Bed leveling Data, Loading my Bi-Linear Bed Data :: This allows you to Print on leveled bed in microseconds

You still have to have the correct nozzle height and filament temperature ect.... that will allow the Filament to stick to the bed.
Because the Proximity sensor says you are at the correct height has no meaning, If the nozzle is way above or below the Sensor.
This is the purpose for a "Thumb Screw Slide Mount Adjustable Sensor". And if you have your thumb screw adjuster color coded in
quarters or even numbered 0 - 9 after a few time making the adjustment you can simple turn the Thumb Screw to that setting,
now you no longer need work making any test prints, to get the separation distance between the two correct.

The same can be accomplished by use of Z-Offset from the LCD controller, changing the Z-Offset value you can raise or lower the nozzle height.

With a starting Z-Offset of -00.50, then changing the Z-Offset numbers to " M206 Z-00.44 " effectively raises the nozzle .06 mm.
So changing the Z-Offset numbers to " M206 Z-00.56 " effectively lowers the nozzle .06 mm from our starting Z-Offset.

You really should use M851 in Marlin, instead of M206. That is specific for the Z-probe. You are globally setting a Z-offset for that axis with M206 which doesn't make much sense.

Thank you for the Information

Installed Marlin 1.1.5 tuned and calibrated running with Bi-Linear Bed leveling that is saved and easily accessible.
Will try the Build surface again to see if I can get any better results than I have in the past.

Already is appears to be holding better than in my first attempts to using the bed surface, however I have a year of printing experience now.
I see the first layer when printing that the Nozzle is definitely following the bed level, before I would have highs and lows (thin and normal layer).
Before I had to come to this perfect nozzle height, that was not to high and not to low to overcome the warp in the bed.
Main reason for the Vinyl transfer paper tape is nozzle height was more forgiving and stuck at a wider nozzle distance from the hot bed.
I use a color coded thumb screw slide mount on my proximity sensor for faster more accurate adjustments to the Z-Axis nozzle height.

New Bi-linear Leveling Grid:
< ----- 0------ 1------ 2------ 3
< 0 -0.356 -0.059 -0.136 -0.213
< 1 -0.023 +0.054 -0.085 -0.240
< 2 +0.083 +0.053 -0.087 -0.250
< 3 +0.084 -0.025 -0.133 -0.258
< 4 -0.001 -0.170 -0.236 -0.311

I have found that
G29 S ; Auto Bed Leveling + Save Data does not work for Bi-Linear
you can still use the M500 to save the data
OR the LCD
LCD Click Menu
Click Control
Click Store Settings
