I have a 100w co2 laser i bought from omtech (MF2028-100w) shorlty there after, i bought the autofocus upgrade kit. People hate it because they forget about the focus pen and eventually end up driving it into the honeycomb.
My question is this: can i add coding to the lightburn program to auto lower the bed upon heading to home? Not sure if i can get into the controller program to do such a task. Figured lightburn would be easiest to change?! Doing this would make it so that the laser head/focus pen would be clear of damage and force me to autofocus each time. Which i am ok with
Unlike GRBL-based controllers, Ruida controllers handle the entire job on their own, allowing no interaction from the outside. They don’t even send a “Done!” notification.
I laid a scrap credit card under the focus pen at the home position so an inadvertent homing operation won’t cause any problem, but that’s as good as it gets.
Forgive my stupidity here, but doesnt lightburn send the request of operations? Meaning you punch all the info into lightburn and it does everything lightburn requests-within the controllers parameters. The controller has an up/down function. I just assumed you could go in and tell the controller to do one of its functions as part of the request in lightburn.
Though now that I am typing this, i am realizing that the home function is a controller thing and the operations request is sent prior to starting, not during stop
Unfortunately, that seems to be an incorrect assumption.
Ruida controllers have a specific configuration for where to place the laser head at the end of the job, after all the cutting instructions are done. My KT332N has these options:
- Docking = home position in the right rear corner
- Origin = user origin (I think)
- Nothing = don’t move after job
It also includes a Focus Distance setting that does not affect the vertical position after returning to that corner. I think it’s yet another offset from the auto-focus position in addition to all the other vertical offsets elsewhere in the controller’s configuration.
I can’t find a similar setting in the 6442 manual, which certainly doesn’t mean it’s not there, but in any event LightBurn doesn’t have any control over what happens.
