How to calibrate a 3D Printer
Your 3d printer is delivering bad and off-scale printings? If the answer is yes, this is exaclty what you need, you will learn how to Calibrate a 3d Printer like a ninja!
Why i need to Calibrate a 3d Printer?
When working with 3DPrinters, we no longer talk about meters or centimeters, the most used units now are millimeters and microns. as more precise things get, more the environment affects the result (and the plastic dilatation / diameter), and mostly the natural stretching of the belts. that’s why we will need to regularly calibrate a 3d Printer.
-A working and leveled 3DPrinter
-A caliper with 0.01mm or better precision (must be in millimeters)
-EEPROM enabled on the 3DPrinter
-Repetier host (click here to download)
-Repetier or Marlin firmware
-STEP/MM calculator and XYZ Calibration file (click here to download)
What is and how to use an caliper?
The caliper is a device to measure length, like a ruler, but the precision is better. If you have never used a caliper before i would like to suggest you to buy a digital caliper, they are a bit more expensive but the price pays off. You will need a caliper with at least 0.01mm precision (or 0.0005″). If you need to buy one, I’ve selected two great options, both delivery the needed precision regardless of the price
Before everything, make an BACKUP!
It’s always good to reinforce, make a backup before any configuration changes, doesnt matters if you are doing something on your computer, smartphone or 3DPrinter, bad things can happen, and they will if you are not ready.
To perform a backup of the configurations on the 3DPrinter you will need the software Repetier Host,
You will need to connect the 3DPrinter to the USB port, press Control + P to open the configuration panel,
Select the port (or leave it on AUTO) and the proper baud rate (usually 115200 or 250000). Press “ok”
on the main screen again, click on connect, and then on Config > Firmware EEPROM Configuration
Now on the EEPROM Settings menu, click on “Export EEPROM Data”, its also a good idea to take a print-screen of all the parameters here, just in case you need to access a single value.
After the firmware backup, we will start messing around on the 3DPrinter.
