Introduction : Anycubic i3 mega auto bed leveling
Fed up of manually leveling the print bed of a 3D printer before printing? In this guide, learn how to upgrade (Anycubic i3 mega auto bed leveling) the Anycubic i3 Mega for auto leveling in steps.
Users will take time to accustom with leveling the print bed on the Mega-S. This guide will help users to become an expert in print bed leveling.
Beautiful print results can be achieved with a perfectly leveled print bed. Problems in printing can occur when the print bed is not correctly leveled. In fact, even the printer can get damaged.
The paper approach is the most effective method for leveling the print bed. First correct the gap between the print bed and the nozzle for sliding down a piece of paper, while retaining some friction.
Setting Up: Cleaning of Print Bed and Nozzle
Start by cleaning the printer nozzle and the print bed. Make sure there is no filament remnants and any foreign particles on either.
Fixing the gap between the print bed and the nozzle is the most basic way to level the print bed.
This is difficult when there are foreign objects between these two components.
If the nozzle has been used, some residue of the filament will have built up. With a side cutter, gently remove it.
Another option is to warm the nozzle and then wipe it clean using a tissue. Make certain there are no filament remains on the nozzle’s underside.
How to Level?
Now that we have made sure the print bed and the nozzle are all clear, it is time to level the print bed. The below steps guide us on how the print bed can be leveled:
Step 1: Start by screwing the print bed in place.
If the 3D printer is already assembled, one can avoid this step.
It is still important to ensure the print bed is firmly fixed down in place, using the screws provided. This is to avoid the nozzle from clashing with the bed.
There is no need for using strong force when tightening the screws.
Step 2: Move the Nozzle to Z-Home Position
One may now use the menu to relocate the Nozzle to Z-Home position. During leveling, one need using the button number of time:
Tools -> Home -> Home Z
Step 3: Align Z-stepper motors Distances
Before leveling, one may require to align stepper motors on the Z-axis. This depends on the setup status of the 3D printer.
On either side, the aim is to achieve an equidistant between the base of the 3D printer base and the stepper motor.
The Z-axis will twist if the left and right distances are unequal. Leveling the print bed can be difficult, if not impossible, and printing errors will be more likely. Hence, these distances need aligning.
The stepper motors screws are used to align the gaps. They’re a little awkwardly situated, but a long screwdriver can easily reach them.
The bottom ends of the stepper motors will protrude further from the stepper motors as one screws them in further. The sooner the Z-stop is engaged, the screw is further down.
The stepper motor stops promptly when the Z stop is engaged, and one can hear a little beep.
When one fixes a screw, one has to first raise the Z-axis a few millimeters upward. Select from Menu, Tools -> Move Axis -> 10 at +Z, then return to Z-Home and re-measure the distances.
The Z-axis will be distorted if the distances are unequal as one approach Home Z position.
Step 4: Align the Print bed roughly to Nozzle Height
After that, one can roughly align the print bed with the nozzle’s height. For the time being, one can use the eye as a gauge.
Move the print bed up on all sides till there is just a small space between it and the nozzle.
One can examine the spacing at all corners and also the center by manually moving the print head.
Ensure the print head is moved carefully and slowly at all times.
The nozzle could clash with the print bed if the same is misaligned and one moves the print head too quickly! Scratches and other sorts of damage may develop as a result of this.
Step 5: Using Paper Method to Level Print Bed
The most crucial step in the print bed leveling is now completed.
The Mega S isn’t the only device for which the paper approach is useful. It’s the standard for all other 3D printers that don’t include an auto leveling system.
The paper method’s purpose is to control the spacing in the print bed and the printer’s nozzle. So as to “only barely” insert a paper sheet in-between.
The “only barely” part is crucial. As the paper must be squeezed only slightly between the print bed and the nozzle through the print bed’s rotational screws.
But only to the point where one can shift it forward and backward against some resistance.
- One won’t be able to shift the paper if the distance is too short.
- One can shift the paper with no resistance if the distance is too great.
It is critical to feel a similar resistance when shifting the paper in order to establish almost an equal distance at all positions.
This is when the provided paper comes in handy. One can also use another sheet of paper if the present one is unusable.
One can also use a caliper gauge to measure the thickness of the piece of paper; which has to be around 0.1 mm thick. Feeler gauges are, obviously, perfect for a professional experience!
Step 6: Recheck All Positions
Once one has got everything in place, double-check the paper in every corner and the middle of the print bed.
Due to the spring action of the leveling screws, when turning one screw, the other corners also move somewhat.
Because one feels like this is endless, one can become easily irritated. So it’s typical if one has to repeat the leveling procedure quite a number of times before one is happy with the outcome.
When using different types of filaments, there may be varying temperature needs of the print bed. There could be significant warping of the print bed as a result of varying temperatures.
Under the circumstances, one should level the print bed again.
An important tip: Under the impact of temperature, some print beds warp. It’s a smart idea to double-check the leveling with a heated print bed.
Step 7: Do a Test Print
Test printing is unnecessary if one has completed all the steps of this guide correctly.
A test print, on the other hand, is a good idea if one wants to be cautious and be more precise. Users can print a number of different test objects. These are readily available on Thingiverse.
With a test print, one can measure the finished product and see where any flaws in the Mega S’s print bed leveling are. This way, one can get closer to the ideal print outcome.
