Here is the image of what happens when I start the file. I beleive it's in the printer start gcode in cura. If you can send me the start gcode and let me know. That would be awesome.

Here's a video about how to setup mesh bed leveling on a printer: https://www.youtube.com/watch?v=vcxM7-VK44k

jony, in the instruction it says put  12 jumpers and then the next instructions it says do 15 jumpers which is right..  also x goes to 0 and y goes to zero but z doesnt move any idea??

[Arron Hoppe]

When trying to autohome, with the nosle near bed level, the x axis starts to move up and the nozle crashes into the wall before anything else moves, and halts the printer. Any idea of what can be causing that..  the firmware is stock from the github from your site, please assist and let us know asap...

possible working firmware from a working printer bot..

Thanks

CERMABOT currently has no self-levelling procedures and sensors. All you need to do is follow the instructions to make sure the limit switch is on a level surface. You also need to make sure that the 6 carbon rods are the same length. When you meet the above conditions, the printer can be used normally. We use open source firmware, and you can upgrade directly.

Please post a video here.

Aaron, it is possible to set the printer up to do bed leveling.

Uncomment this line in your firmware configuration.h:
#define AUTO_BED_LEVELING_BILINEAR

Then uncomment these two lines:
#define PROBE_MANUALLY
#define MANUAL_PROBE_START_Z 1

This will add a menu to your LCD screen under Prepare -> Bed Leveling -> Level Bed. You will have to home everything first though.

It just means that it will go to several points on the bed and at each point you have to adjust the height of the nozzle up and down using the LCD screen, then when it completes you have to save the settings so you don't have to do it every time you power up. Then either in your firmware in configuration.h you have to set this line and remove the '//' at the beginning and upload it to your printer: //#define RESTORE_LEVELING_AFTER_G28

An alternative is in your slicer put the following commands before a print starts:
G28
M420 S

Arron,

The extra jumpers are for a second extruder and are not necessary. If you have them there is no harm in putting them in.

I did this but was missing the menu option to begin auto level. To get it working I also uncommented: #define LCD_BED_LEVELING

You should download the latest config files from the Cerambot Facebook group. It has thelatest updates including instructions on how to set things up.

Shortly we'll have the config files for Marlin 2.0 as well
