XYZ Calibration & error messages (MK2)
XYZ calibration is the decisive moment which will tell you how well you have assembled your printer. Essentially it is measuring the skew of your X/Y axis and compensates for any imperfections. It will give you two sets of error messages [compromised/failed]. More about that in the following article.
During this first process only the four main points are being measured - Front, Right, Rear and Left one.
In the second round all nine points are being diagnosed. All of the compensations are then being stored in non-volatile memory. This routine is called Mesh-bed levelling.
What does each of the error messages mean?
Initial XYZ Calibration error messages
"XYZ calibration failed. Bed calibration point was not found."
= Printer was unable to perfectly locate the initial calibration point.
"XYZ calibration failed. Please consult the manual."
= Calibration point was not found at all.
"XYZ calibration failed. Left front calibration point not reachable."
"XYZ calibration failed. Right front calibration point not reachable."
"XYZ calibration failed. Front calibration points not reachable."
= Printer was unable to find Left, Right or Front calibration point.
"XYZ calibration compromised. Left front calibration point not reachable."
"XYZ calibration compromised. Right front calibration point not reachable."
"XYZ calibration compromised. Front calibration points not reachable."
= Your printer was able to finish the initial calibration. However, your Left, Right or Front calibration point was just in the middle of passing the calibration or failing it. That means you should be able to use your printer. Yet we advise you to check out following tips on how to improve your XYZ calibration.
Mesh bed levelling error messages
"Bed leveling failed. Sensor didnt trigger. Debris on nozzle? Waiting for reset."
"Bed leveling failed. Sensor triggered too high. Waiting for reset. Bed leveling failed."
"Sensor disconnected or cable broken. Waiting for reset."
= Your printer was able to finish the initial calibration. However there is something wrong with your PINDA probe position.
If you would see any of these error messages, then most likely there is something wrong with the assembly of your printer. So please do the following:
- Make sure that you have followed the instructions on the LCD precisely. Especially make sure that your X-axis was moved to the very top. Otherwise your X-axis might not be perfectly level.
- There is nothing blocking the movement of any of the axis.
- Double check that your got 100mm (3.937inches) distance between the Y-corners and the frame.
- Go to LCD - Calibration - Auto-home. Your PINDA probe then must end in the centre of the 1st calibration point and the last one (check the photo bellow). Also make sure that your PINDA probe is roughly 1mm higher than the tip of the nozzle.
- Rather unlikely, yet there is a chance that your PINDA probe would be defective. The easiest way how to check that is to go LCD Menu - Calibration - Show endstops. While placing anything metal (e.g. spatula) under the PINDA probe. The endstop reading should change from 0 to 1.
