The controller seems to think the machine is twice the size than it really is. Any design that is created in lightburn will burn at twice the original size. I feel that it is a setting inside lightburn that I have not fond.
When I use Engraver Master, it work perfectly.
Sounds like you haven’t calibrated your machine. You have bed size to program in, then stepper info. Cut as large a square as you can and stay inside the boundaries. Measure the actual cut vs. what it should be and enter those numbers then retest. If you are as off as you say you are, you may need to run it a couple of times to get it spot on.
Dave01, thanks for the input. I think I have already done that. My machine is not a big name machine it is a Bachin Laser Engraver, D8-4050P-2500mw. I had used light burn and also used Engraver Master on the machine. I did a mechanical change, I added a mechanical vertical adjustment to the laser head and the machine went south. At first light burn couldn’t get the machine to move. Using Engraver Master the machine would perform perfectly. I reset light burn back to factory default settings. This allowed the machine to function with lightburn, except it thinks the bed is twice the size and produces designs at twice the desired size. When Lightburn discovers the machine it returns the correct information and size.
I am looking for a variable setting inside light burn that controls scale.
Help!
Can’t help you there. Hopefully one of the LightBurn people will chime in. Lightburn SHOULD be picking up the info from your controller.
I’d suggest starting with Edit->Machine Settings->Calibrate Axis for X and Y. That will get things burning to the correct size.
Thanks for the input, I did exactly what you said but to no avail. I think I may have damaged a stepper motor as I can not get the machine to move in the X axis, the carriage moves in the Y axis ok using the move commands in the Engraver Master program, I can not get it to move from LightBurn at all. I have not been able to contact the seller about replacement parts either. This was a Amazon purchase that didn’t work out.
When did this happen? Immediately after the recalibration?
Can you run this command in Console and return the output?
$$
I tried the $$ command and got nothing. I think I have a damaged part.
Do you see a COM port assigned in Device Manager->Ports?
If so, make sure that same port is selected in the Laser window of LightBurn.
yes, I am aware of the com port. I do have communication to the machine, it just is not doing what it is supposed to do.
What message do you see in Console when you first connect?
Are you absolutely sure that entering $$ in the Console and pushing enter does not return any results?
It seems to be communicating correctly although it looks like you’re having a problem with homing. Do you have “Auto-home on startup” enabled in Edit->Device Settings? If so, can you confirm that your machine has homing switches and was previously homing correctly?
