MarlinFirmware

Personal tweaks and builds of marlin 3d printer firmware repositories.

Source code is here: https://github.com/ThomasToka/MarlinbySynman/tree/bugfix-2.1.x-tweakedbyThomasToka

Instructions:

Please do the following two tests:

1.)

• best is to start with a leveled bed
• flash the firmware
• reset to defaults via screen
• heat up nozzle and bed to your desired temerature
• g28
• got to leveling on the screen
• got to point 2
• set initial z-offset on this point that it has a around 2mm clearance (this is not final leveling
• go to points 3,4,5 an check if it nozzle to bed matches point 2, turn the wheels under bed to patch those 2 mm..
• go back to point 2, lower your z-offset to your desired height via screen (paper method, gauge, etc)
• go to points 3,4,5 and adjust those with the wheels to match point 2
• go around 2-3 times
• do not touch point 1
• go to leveling -> auto leveling, press start
• after this your are ready to print
• watch your g-code for the x position of your purge lines. your bad now starts exactly at x=0 and y=0

2.)

• best is to start with a leveled bed
• flash the firmware
• reset to defaults via screen
• heat up nozzle and bed to your desired temerature
• g28
• got to leveling on the screen
• got to point 1
• set initial z-offset on this point that it has a around 2mm clearance (this is not final leveling
• go to points 2,3,4,5 an check if it nozzle to bed matches point 1, turn the wheels under bed to patch those position..
• go back to point 1, lower your z-offset to your desired height via screen (paper method, gauge, etc)
• go to points 2,3,4,5 and adjust those with the wheels to match point 2
• go around 2-3 times
• do not touch point 1 after your can go around 2,3,4,5 with same height
• go to leveling -> auto leveling, press start
• after this your are ready to print
• watch your g-code for the x position of your purge lines. your bad now starts exactly at x=0 and y=0

What is interessting in those two tests:

1. is your nozzle z-offset correct when the print starts on both?
2. are there any differences between those two tests in the resulting shown z-offsets?

Be carefully with your printer. Mine works fine. But this is a test. So have your fingers near the power button when lowering your z-axis.

Please open an issue if there is something wrong.
