Need Help! Ortur Laser Master 2, Laser Calibration issues

LightBurn Hardware Compatibility Ortur Lasers

I was visited by the laser fairies a week or so ago… Now all of my measurements are off, for example: I make a square 100mm X 100mm. The burned square measures 105mm X 105mm.
I have already taken the following steps to try and rectify the issue:

  1. Updated the firmware to 140
  2. Watched the youtube video of the guy giving X & Y axis, made corrections and it only got worse.
  3. Completely uninstalled Lightburn and reinstalled it, measurements still off
  4. Belts are tight, the laser can move with gravity

What are you current settings for firmware? Type $$ into the ‘Console’ and post what gets spit back for review.

So, are these setting correct or should we change them. I saw a YouTube video where it says $10 should not be higher then your max laser speed. What is the $10=3 actually telling me? If I need to change these settings how do I do that?

$10 - Status report, mask

This setting determines what Grbl real-time data it reports back to the user when a ‘?’ status report is sent. This data includes current run state, real-time position, real-time feed rate, pin states, current override values, buffer states, and the g-code line number currently executing (if enabled through compile-time options).

Report Type Value Description
Position Type 0 Enable WPos: Disable MPos:.
Position Type 1 Enable MPos:. Disable WPos:.
Buffer Data 2 Enabled Buf: field appears with planner and serial RX available buffer.

Here is what every setting does:

You can make changes to your firmware settings from the ‘Console’ window by entering $$ followed by Enter / Return to view the current list of settings. Enter the one you want to change, in this example I will change the ‘Enable Laser’ status, so I would enter $32=1 followed by Enter / Return to set On. You can then check this was successful by entering $$ followed by Enter / Return again to view the change set as expected.

You can also use ‘Edit’-.‘Machine Settings’ from the LightBurn menu. :slight_smile:
