Cr-10 v2 Custom Levels for Z Alignment

thingiverse

I created these (along with custom Cura start and end gcode) to help with the well-known Z-axis alignment issues on the Cr-10 v2. There are cutouts to avoid the sensors and wiring. This has helped me greatly by using the following process: Initial Setup: 1. Auto-home 2. Raise Z axis to approx 38 mm 3. Move X axis to the right to make room for levels, put the levels in place along frame on the left and right side so that the cutouts match up with any sensors or wiring that might be in the way. 4. Put custom start and end gcode snippets in Cura under machine settings (your selected printer should be CR-10s btw since Cr-10 v2 is not an option yet) 5. Disable steppers and use lead screws to manually lower the z axis onto the levels, making sure to place both sides on the levels simultaneously if possible - This step can be repeated if you find your first layer looks loose, just adjust the way you do it. 6. Export a bed leveling print of your choice from Cura, it must be recreated so that it includes the code included (BE READY TO REMOVE LEVELS WHEN THE EXTRUDER REACHES TEMP AND THE Z-AXIS RAISES, YOU HAVE 5 SECONDS!) Once your bed is level: 1. Put the levels in place (unless machine has been powered off, then Auto-home and raise axis using menu system. If you don't have the axis in the right place you will get stuck on the levels. 2. Disable steppers and manually lower the Z-axis 3. Print model of your choice (made in Cura, with start/stop code additions) 4. Be ready to remove levels With this process I have been able to get very consistent prints, with rarely re-leveling the bed, despite not having any anti-backlash nuts installed, or any other suggested fixes. I hope it helps someone else. The CR-10 v2 gives fantastic results, but this particular problem is a nightmare until you figure it out.
