Intro
- D3D Marlin covers code up to calibration.
- Code works for following the 3D printer - such as Yousef's twisted axis.
- Initial code used - April 29 - see April 29 version of D3D Marlin.
- Lulzbot Cura initialization file used - File:D3DLulzbotCura.ini
- See instructable on auto bed level - [1] - it says to use G92 to implmement the z offset correction.
- What is the difference between G92 Z1 and M851 Z1?
- See Marlin Gcodes
- Marlin_main.cpp is main code
Action
- Diable EEPROM - it could be storing one value and never updating from print to print. [2]
- V Set the verbose level (0-4). Example: "G29 V3"
- Try Mattercontrol software [3]
- Check usign G1 Z0 command to see where the print will actually start printing - it should go to the first layer height set by the probe. - comment by Martin at [4]
- Contact Ryan Lutz at Matterhackers - see leveling troubleshooting - [5]
- Probe starting in the center. Find the center coordinate after zeroing. There may be weird things happening when probing is too close to edge (30mm or less) [6]
- As the last step in start gcode - move bed to required height, while leaving firmwar offset zero[7]:
