Get to know the basics of your M3-ID Rev1
Thanks to its new probe, the M3-ID Rev 1 has several new features. This article will give you a brief overview of those features and how to adjust your printer's settings.
Before You Begin:
- Follow all "Getting Started" instructions listed in your User Guide.
- Follow all configuration, connection, and login instructions to access your M3's control interface.
M3-ID Rev1 Features
The M3-ID now used the probe to set the starting height for your prints. This will be enabled automatically when homing the Z-Axis in the Octoprint 'Control' tab.
A physically leveled bed will always give you the best results while printing. Using the new probe, the MakerGear Setup plugin in Octoprint can help you level your bed. Octoprint will probe your printer's bed, then give you specific instructions on how much to adjust each corner of your bed.
To use assisted bed leveling, open the "MakerGear Maintenance" tab in Octoprint and click 'Bed Leveling'. Now click on 'Assisted Bed Leveling" and follow the instructions on screen
Before each print, the M3-ID Rev1 will automatically probe 9 points on the bed. This will allow the M3-ID to create a mesh 'map' of your bed. Based on this mesh, the printer can compensate for slight variations in the bed.
The 9-point mesh leveling process is automatically activated with a standard homing gcode
If you do not want to use mesh leveling, change your file's starting script to
Note: This will still use the probe to set the starting height, but no mesh leveling will be used.
In order to protect the probe from colliding with the bed clips, the M3-ID firmware will disable the front and back 11mm of the bed. The 0 origin for Y is now 11mm into the bed.
Some areas of the front/back of the bed are still accessible, but you must take care as to not let the probe collide with the bed clips. To disable the safety lockouts, use the command
To re-enable the lockout use
Also keep in mind that T0 must be moved in order to allow T1 into the lockout area, or the probe will collide with the bed clips.
We recommend that any gcode you run on the M3-ID R1 is created using the profiles created for the M3-ID (see this article for more information) to make sure that all parts fit on your bed. New starting scripts also take advantage of the bed geometry for purging.
