How To Set Z Offset Ender 3 V2

Footstep i: Determine and Prepare Z-commencement

Afterward installing the new firmware and the BL Affect /CR Bear on on your printer, to apply the auto-leveling capabilities we have to first determine the Z-offset required

First, machine-habitation the printer. From the main card, select "Prepare > Auto dwelling". You volition realize that the printer now homes to the center of the bed instead of the bottom corner.

With the BL-Impact the Auto home function does not bring the Z position to 0. To adjust for the Z-start, we must first move the nozzle position to 0. To practice so, select "Motility > Movement Z > 0.0". To prevent any accidental bed scratching, place a piece of newspaper at the lesser of the nozzle on the bed earlier moving the Z centrality.

At present, to fix the Z-offset, select "Back > Z-offset" and offset to decrease the Z-get-go value. Negative values mean the nozzle moves down. Get-go with decrements of ane followed past 0.ane and 0.05 until you feel some resistance against the paper nether the nozzle. Note that the nozzle just moves after yous set the value and press the button to confirm. We find that typically the offset is somewhere between -ii.50 to -three.fifty.

TIP: If you lot find that after you set a new Z-offset value, the motor does not move, modify the Z-offset back to 0, auto-home again, movement the Z-axis down as above and try over again.

TIP: If your nozzle has some remnant filament from your previous impress, heat up the nozzle and clear it away earlier doing this stride every bit the backlog stuck filament volition bear upon the resistance you feel under the paper.

Step 2: Level Bed and Test Impress

Later the Z-axis offset is correctly set up, it is fourth dimension to test the machine bed leveling. Select the "Level" choice on the main screen and look for the car leveling to be complete. The nozzle volition move to 9 positions on the bed and measure out the off-set values for each point, so that when you impress a model, the printer takes into account the off-ready values and prints higher or lower accordingly.

TIP: If at whatsoever point the BL Touch starts to flash blood-red and the probe does non move, it ways that the probe got stuck. To fix this, turn off the printer and manually pull downwards and push in the probe and restart the printer. If this happens very often, it might exist time to change the probe which is also included in the kit.

Once the printer is washed with the motorcar leveling, the next step is to do a test print to check that the leveling went well. We have adapted a GCODE file from CHEP to do just this.

Re-create this file into your microSD card and insert into your printer. (Remember to remove the firmware .bin file if you accept not already if not the printer might reflash its firmware over again) Select impress and the printer volition start to heat upwardly and print the following grid pattern.

Notation: Go on a finger on the power off switch to turn off the printer speedily if y'all see that the nozzle is going as well low and is starting to scratch the bed.

To check the leveling, make sure that the test pattern printed is not too low or too high. If it is besides low, y'all will not exist able to see the filament printed out and in worse cases the nozzle will start to scratch the bed. If information technology is too high, the filament will be printed in the air. If y'all rub you finger lightly on the print, the filament should not come off as well hands.

If you need to suit the Z-offset, yous tin do so during the impress. If yous observe that 1 corner is as well high or too low, you tin can suit the wheel manually during the print every bit well. Do a few of this examination print to brand sure that the leveling is good earlier starting to print your models.

NOTE: Whenever the printer is moved, we recommend doing the bed-leveling process again (Starting from Step 6) to prevent whatever accidental bed scratching.

NOTE: As of the time of writing, the firmware (V1.one.i) of Ender iii V2 stores the BL Impact bed leveling data in the microSD card instead of the motherboard's EEPROM. This ways that you will need to re-do the leveling process if you change a microSD card.
