The update light burn for a we creat laser

[chrisfulcher]

Hi Aron, when I run the focal point test it starts off fine but as soon as a “move Z” command is given the head goes all the way up to maximum height.

Eventually, we should send them to WeCreat

I believe someone have already told Wecreat but not sure, I posted a device almost 2 years back

Focus Z button for WeCreat (shown in the WeCreat Camera calibration video)

And if you press Alt + Shift + Z ? [image] Checked now with a WeCreat device the button does not appears. Checked and only the Custom GCode devices have it. . Maybe if you create a new device as Custom GCode with your WeCreat and GRBL flavor… . Check if the following one works WeCreat_Custom GCode.lbdev (3.9 KB)

The machine might be using an offset

@chrisfulcher maybe you would want to make the Z Offset Default to all Layers, the Wecreat site have some tips:

See if enabling “Relative Z Moves only” in the Device Settings helps.

I ran a few more tests on our Vision, and couldn’t get Z-Steps per pass working.
The machine has a mind of its own and decides to randomly lift the Z-axis during the last pass without turning off the laser.
It then returns to the home position but Z remains at the current height.

The Z-Axis in Device Settings should be disabled until someone can find a workaround for this.

The Focus-Z function will still work when this is disabled. We only send the machine their custom command M130 and the firmware of the laser starts its focus sequence. That is: Move the head down until the material is detected, then move X & Y to the homing position. (The only way to prevent it from moving X Y after homing, is by using our “Focus Center” macro M130X200Y150.

Hi Aron we are getting the same results, I have tried multiple iterations and my vision P will not execute any Z steps per pass operations, I have not gone back tot the WeCreat SW, but I remember reading (paraphrasing from an old memory) somewhere that this function was a “propriety add-on directly controlled in the material selection portion of the SW and linked to to the LIDAR function of the laser”.

From wecreat using Z stepdown with LB - Multi-Pass Drops (Beam Assist): Because the Z-axis is unlocked via the configuration file, entering a negative value (e.g., -1.0 mm) into the Z-Step per pass box on your cut layer will automatically step the motor downward on consecutive laps without needing custom macros

[chrisfulcher]

Is this configuration is a crash waiting to happen?

I am assuming though again these Z step per pass moves are calibrated to the focal distance only and will inhibit any more Z moves past the known focal length of the laser? Focal length in this case being the height above the work piece as set by the LIDAR.

And just as a general update, the vision pro has been banging out product using lightburn for 2 days straight without a single issue using a range of materials and thicknesses, mind you I do not go any more than 6mm - 7mm thickness material, I do the thicker material cuts on my Co2 laser.

This is interesting. I couldn’t find this setting in WeMakeIt. Do you have a link to where you found this information?

Hi Aron, I got this from a AI search

[chrisfulcher]

1. While still inside the layer settings menu, type the exact thickness of your stock into the Material Thickness (mm) box.
2. Set your Number of Passes based on material density (e.g., 2 passes for 12mm pine, 4 passes for deep hardwood).
3. In the Z step per pass (mm) input box, define how far the machine should physically sink after each loop.
   • Recommended Step: Input 0.5 mm to 1.0 mm per pass. This moves the condensed 45W focal point directly into the center of the fresh wood groove on each pass, mimicking the “Enhanced Cutting” feature from WeCreat’s native software.

The AI seems to be halucinating here.
I don’t see an option for a “Z Step per pass” in MakeIt.

Also no mention of such a feature on their docs page:

@chrisfulcher

the Z-axis is unlocked via the configuration file

Did you find this configuration file? That’s the first time I’ve heard of this.

[chrisfulcher]

Seems like it, thanks for sleuthing this.
