Platform calibration is one of the maintenance procedures which involves checking the distance between the nozzle and three points on the platform, and tightening/loosening the calibration screws placed under the platform. It helps to lower the risk of printing problems, including warping or incomplete first layers. You should calibrate the platform before the first print, whenever you notice adhesion problems, and after carrying out platform maintenance. There are two types of platform calibration: automatic and manual. The manual calibration is recommended when using a glass plate or when you cannot finish the automatic calibration. This manual shows how to properly carry out the manual platform calibration.
|Remember to prepare a piece of paper (A4 size) for this procedure.|
|The following manual shows the M200 Plus manual platform calibration. For the M300 Plus and M300 Dual, this procedures are the same.|
Preparing for Calibration
Before starting the calibration, make sure you have tightened the three calibration screws placed under the platform to approximately the same level.
Next, open the Tools menu, select Platform and then Manual Calibration.
The printer will lift up the platform and display the first message containing instructions on manual calibration.
Lifting the Platform
In the first step, push the UP button until the platform is about 1 mm [0.04 in] from the nozzle.
Tightening Back Screws; part 1
Rotate the back left screw until the platform is about 1 mm [0.04 in] from the nozzle.
Next, rotate the back right screw until the platform is about 1 mm [0.04 in] from the nozzle.
Adjusting Platform's Distance
Prepare the piece of paper and place it between the platform and the nozzle. Next, adjust the platform’s distance using the UP/DOWN buttons until you feel slight resistance when moving the paper.
Tightening Back Screws; part 2
Rotate the back left screw until you feel slight resistance when moving the paper.
Next, rotate the back right screw until you feel slight resistance when moving the paper.
