3D printer is no longer foreign to most of us in Malaysia. Just have a look at social media like Facebook or Instagram, people out there show high interest in starting a new hobby with 3D printer.
However, we often received comments, direct messages (dm) and Whatsapp messages asking on how to assemble ET4 3D printer, how to troubleshoot ET4 3D printer, how to create a design and more question ‘how to’ regarding ET4 3D printer.
Using 3D printer might be quite challenging for a beginner but this ET4 model comes with special features which is auto-levelling. So, it is best to say that with ET4, there will be no problem to adjust bed levelling as it is an option for users to choose whether to auto-levelling the ET4 bed or manual-levelling the ET4 bed.
Let’s get started with step by step guidelines below.
The tutorial divided into three parts: levelling sensor check, auto-levelling and manual-levelling.
Checking levelling sensor is the most crucial part as levelling sensor can affect the printing accuracy.
You will need to prepare your tools. Here is the list of tools that you need to use to adjust your ET4 levelling: slot type screwdriver, 4mm Allen wrench, 1.5 Allen wrench and A4 70gsm paper.
Step 1: Preparation Before Levelling
First, you need to check the sensor using screwdriver to ensure the sensor light is working. This is to confirm that the sensor light can detect the accurateness genuinely.
Second, you need to check distance between the nozzle and the bed plate.
Third, the optimum height distance between the nozzle and the bed plate is 0.2mm for all sides: front, left, right and back.
Step 2: Auto-Levelling
On the Home button, click Prepare > Level > Auto > OK for auto-levelling. Once the nozzle starts to touch the bed plate, the levelling begins. This may take a few minutes to complete.
Next, to confirm the auto-levelling is successful, you need to see the error range from maximum to minimum value falls within ±0.5mm. Let’s say the error range value doesn’t hit ±0.5mm, you have to adjust manually by clicking on (+) and (-) button for calibration.
Don’t forget to click OK to save the data!
Step 3: Manual-Levelling
First, click on Prepare > Level > Manual > 1,2,3,4 > OK. Place the A4 paper on bed plate and you can start adjusting your levelling. You may select between (1,2,3,4) button and the nozzle will go to the points selected.
Second, check the gap (height and distance) between the nozzle and bed plate. Moves the A4 paper that you placed earlier, drag slightly the A4 paper against the nozzle to check the friction and smoothness. Little friction against the A4 paper determine that your levelling is successful.
Third, click OK after you have check each points. The nozzle will go to the center. After you have finish adjusting all points, click OK again to finish manual levelling.
Final Step: Slicing out and Printing Design
After all of your hard work in adjusting your bed levelling, you can start printing and look for the final result. To verify that your calibration is well adjusted, you have to print this free design and check each of design (insert link). There are 3 types of condition of the printed design that will let you know if the levelling is successful or not.
The filament test for this condition has hollowly surface and too thin. This means your adjustment is unsuccessful, probably the nozzle is too high, you need to raise the bed plate.
The filament test for this condition has bumpy and rough surface. This means your adjustment is unsuccessful. Probably the nozzle is too low, you need to lower the bed plate.
The filament test for this condition has smooth and perfect surface. Perfect adjustment with 0.2mm gap. Meaning that your adjustment is successful.
These 3 types of condition will let you know whether the adjustment made is precise or not. Otherwise, you will need to repeat the steps from beginning to adjust again your bed levelling.
