How to Best Tune Bed Leveling on Anet ET5 3D printer-Part 3
III – Sensor Assisted Manual Leveling ET5 Print Bed
Heat up the print bed to 60 degrees Celsius.
Every time when we do manual or automatic bed leveling, we must heat up the print bed to 60 degrees Celsius first.
The print bed also follows the principle of thermal expansion and contraction. If you don’t heat up the print bed while leveling it, the spacing between the bed and the nozzle becomes smaller while you make a print because the heated bed expands a little. This will result in improper extruding from the nozzle.
Click on “Prepare” and then select “Level” on the touch screen.
Click on the “Manual” option once and we starts manual leveling mode. And the nozzle automatically moves to its home position (the center of the print bed).
Place a post-it note under the nozzle (not under the sensor this time) and slide it to feel the friction between the bed and the nozzle.
In this case, the friction is too much when sliding the post-it note. Hit the “+” button several times to gradually raise the nozzle higher until the paper can slide a little smoother.
If the friction is too weak, click on the “-” button to lower the nozzle.
Then move to the four corners to have necessary adjustment. Click on “1” and the nozzle moves to the first corner. Place the post-it note below the nozzle and slide it again to feel the friction.
Adjust the print bed height with the knob under the bed according to the friction or tightness when slide the post-it note. If it’s too tight, lower the print bed; if it’s too loose, raise the print bed.
If we have to adjust the print bed too much to acquire an appropriate spacing to slide the post-it note here. Then we should go back to previous step to reset the home position Z offset value.
Click on “3”, “2” and “4” to finish leveling the rest three corners of the print bed according to above procedures.
It’s recommended to double check the leveling several times.
Click on “Ok” and the hot end moves back to the home position.
Place the post-it note underneath the nozzle and slide it to double check the Z offset value. In this case, it feels just perfect to slide the paper and we have the print bed perfectly leveled here. If not, adjust it according to step 4.
Now we’ve done the sensor assisted manual bed leveling completely. We’ll proceed to auto leveling to further enhance the accuracy of bed leveling.
