Machine bad distance , don t work

LightBurn Software Questions
1

I have two laser machine engraver , 3018 and 6550.
The software on 3018 if I send command to move 1mm , machine move 1mm
The software on 6550 if I send command to mode 1 mm , machine move 10 mm , this is bad and is impossibile to use.
Why ?

It sounds like each machine has a different stepper distance. Need to measure/adjust for each.

Yes i have fix this , but i have another problem, if i move on the track the laser it go correct in position, when i start engraver start at 40mm up in Y …

Sounds like the steps per mm numbers in the settings are 10x too high. These would be $100 and $101 in the GRBL settings. You should read up on how to configure GRBL - if the board didn’t come pre-configured for the 6550 machine you’ll have some changes to make. https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration

If the laser does not have homing switches, you’ll need to zero it manually, or use the ‘Current Position’ mode in LightBurn - Absolute Coords and User Origin will not work unless the laser is zero’d.

What is your setting for 10, and when you type # in the console, what does it say?

I type # return:

error:1

And 10 configurate = 0

Sorry, that was supposed to be $# - try that.

Well there are no offsets applied, so if you power on the machine with the laser head at the front left, it will probably all work as expected, assuming that the directions in that machine are normal.

if i power on the machine with the laser head at the front left and i ask machine go in x 100 and y 100 the machine go correct in x 100 and y 100 but if i play engraver for make a write “ hello “ in x 100 and y 100 machine start in x 140 and y 100 …
