El laser graba a unos centimetros de donde le dices desde lightburn y la camara (The laser records a few centimeters from where you tell it from lightburn and the camera)

Aunque todo el proceso de calibrar objetivo, calibrar cámara y actualizar superposicion se hace bien y las primeras veces el laser va al sitio y lo hace bien, "enseguida pierde la posición y lo que tiene que grabar en un objeto el laser se desplaza unos centimetros y no sale en su sitio la grabación.
El proceso lo he realizado varias veces y de principio todo sale bien pero despues pierde la alineacion y ya sale mal.
Espero me puedan ayudar

Although the entire process of calibrating the lens, calibrating the camera and updating the superimposition is done well and the first times the laser goes to the site and does it well, "it immediately loses its position and what it has to record on an object the laser moves a few centimeters and the recording does not appear in its place. I have done the process several times and at first everything goes well but then it loses alignment and it goes wrong. I hope you can help me

There are two types of things that cause this, Lost Motion and Restarting away from home.

The stepping motors that move the gantry ‘follow steps’ that are counted by the controller.

Lost Motion is most often seen when the laser engraver slips because of excessive speed, loose belts or a set-screw loosening. This can produce different results each time a job is completed. The controller only sees the position that it has counted - not the actual position of the head of the engraver.

The first things to check to look for a lost motion problem are:

  • Verify the units of speed are set to mm/minute. The units of speed are important and often overlooked.
  • Test to confirm that the belts only move a small amount by hand but are looser than a guitar string.
  • Confirm that the screws in the pulleys are tight by retightening them with the Hex-Wrench. Note: These screws can come loose over time and cause lost motion.

Mechanical Binding and damage to the motor wires also cause Lost Motion but are not seen as often. I can walk through testing these after you confirm the more common causes above.

Restarting away from home is most often caused by a weak or marginal power supply, poor or noisy line power at the plug in, or a short-circuit in the engraver wiring.

When you start the engraver and connect to LightBurn you will see an initial message in the Console window in LightBurn. If the power supply is weak or power from the power supply is interrupted the laser will shut off and restart. When this happens, the Initial message in the Console window is Repeated. Some engravers will set 0,0 wherever the laser engraver turns on.

Verify the Engraver does not restart when the laser is working by watching the Console window.

Please also note any error messages that are visible in the Console window in LightBurn.

Thank you for your extensive solution, the X4 PRO machine is new, it’s been there for a week, all the rubber bands, belts, etc. are in perfect condition, today I managed to align and calibrate the camera by putting a white cardboard on the bottom of the X4 PRO machine, I have finally managed to get what I want to come out within the measurements of the wooden support, I will review your steps just in case, but in principle everything is already correct.
Thanks again John, greetings from Spain
