Ever stumbled upon the bizarre scenario where your 3D printer whimsically starts its magic on a random corner rather than the central stage? Yikes, I feel your pain! That’s why, being the tech enthusiast I am, I dived deep into this riddle. You can rectify a 3D printer that’s reluctant to print smack in the middle by tweaking the bed specs in your slicer—given that they’ve been fed incorrectly. The esteemed Cura slicer offers special nozzle offset adjustments for X & Y to refine the nozzle’s stance. Remember, recalibrating your firmware to command the center stage is a viable solution too.

Confounded about why your 3D printer kicks off in a corner? The culprit often lies in the mismatch between your real-deal printer’s bed size and the dimension set in your slicing software. Imagine having an Ender 5 and mistakenly setting up for an Ender 5 Plus in Cura—it’s no wonder the printer waltzes off-center! The firmware lurking inside your 3D printer, if misconfigured, can lead to such misadventures. But fear not, solutions abound, and we’re diving right in!
To untangle this, let’s embark with simpler remedies, saving the intricate ones for later. If the mismatched bed metrics in your slicer are the villain, it’s an easy fix! Either locate your printer’s legit bed metrics in the Slicer or hand-feed them by crafting a bespoke 3D printer profile. A myriad of profiles for myriad 3D printers await, so you’ll likely find your fit. Note that models like Ender 5 and Ender 5 Pro might share similar dimensions—feel free to swap profiles, but ensure their sizes truly align.
A hidden gem in Cura is the “Origin at Center” toggle. It can be your quick knight in shining armor, especially when most 3D printers designate the starting point at the front-left corner, not the heart.
Should you need to delve deeper, it’s about recalibrating your printer for a fresh center point. A few stages are paramount: Ascertain your 3D printer’s innate origin point. Decode the deviations from your X and Y endstops. Implement the remedy, be it endstop realignment or offset application in the slicer. Often, the firmware determines your printing’s commencement—let’s set it right!
To spot your print bed’s true nucleus, draw diagonal lines from opposite corners. Their intersection unveils the bed’s heart. For better visibility, use Blue Painter’s Tape on the bed. Ensure your firmware can be flashed for modifications to take effect. By 3D crafting a crosshair, you can determine your printer’s deviation from the target. Armed with this knowledge, it’s firmware recalibration time! A handy tool for this quest is the Bed Center Calibration Model from Thingiverse.
When tuning via Marlin, kickstart by pulling up its configuration file. Pinpoint the “X_MIN_POS” value, which, for calibration’s sake, should be set to 0. This ensures a reset, laying the groundwork for precise recalibration.
Now, employ Pronterface or OctoPrint for the driving seat of your 3D printer. Once synchronized, hit the ‘Home’ icon to set your printer to its base. With that, steer the nozzle towards the previously marked center, noting down the deviation metrics.
To crack the new offset, deduct the printer’s display values from the bed’s midpoint. The resultant offset needs to be fed into the Marlin configuration, specifically the “MANUAL_X_HOME_POS” & “MANUAL_Y_HOME_POS” lines. Post the firmware upload, test-run by directing the nozzle to your bed’s midpoint using commands like G0 X110 Y110 Z2. Once aligned, you’re golden!
Lastly, for those Ender 3 users, Cura comes to the rescue! Adjust using the “Nozzle offset X” and “Nozzle offset Y” settings to ensure your prints grace the right spot on the bed. It’s accessible via Preferences > Configure Cura > Printers > Machine Settings > Extruder 1 Tab. Positive and negative values adjust the print head’s position, ensuring your prints always strike gold.
Videos do explain it best, but with this guide, you’re well-armed. So, no more corner-printing shenanigans!
