Having to reconnect laser everytime door is opened

[aaronxyzee (Aaron Moore)]

Hi
I’m new here so please forgive any oversight.
I am having problems with a newly overhauled Lasersaur, now using GRBL and an Openbuilds Blackbox controller. Every time I open the door I get this message [MSG: Check Door]. In order to carry on working I have to disconnect and then reconnect the machine. It does not do this when I use the Openbuilds controller. Is there a setting in Lightburn that I am missing
Thanks
Aaron

This is not a LightBurn setting / configuration. This is a controller feature:

Thanks for reply.
I have been through the set up process described in the link and I don’t have the same problem when I run the Openbuilds Control software. In Openbuilds control there is an unlock button in the gui, is there anything similar in lightburn?
Thanks
Aaron

Are you wanting to maintain the door protection? If your desire is to override the door protection, you could jumper the door output on the controller.

Laser stops randomly

Hi I have been cutting fine on my laser for months and today I was working on a project and the laser stops at random intervals. here is my console output G1X110.3Y54.8 G1X109.57Y53.09 G1X108.79Y51.41 G1X107.97Y49.74 G1X107.11Y48.1 G1X106.21Y46.47 [MSG:Check Door [MSG:Check Door Door:2|MPos:134.682,26.554,0.000,0.000,0.000|FS:0,0|WCO:0.000,0.000,0.000,0.000,0.000 Stream completed in 3:13 Port opened, waiting for response. no idea where the Check door has come from.

This thread is a bit dated, so maybe current versions of LightBurn are different. I live in the DSP world for my laser, so I am limited on familiarity with other controllers. @LightBurn may have more current advice.

Grbl 1.1 Door as feed hold

Per the Grbl 1.1 docs we have the door tripping the feed hold and enable in config.h for this to be treated as door open. However when the door is closed machine does not resume. If the door is opened other than during a cut, typing ~ does resume and return control of the machine. However if Lightburn is sending a job to grbl and the door is opened there is no way to resume as it would appear lightburn doesn’t send the realtime commands .

I just want to be able to use the laser as soon as the door is closed.

Ideally I would like to be able to set up a job and run a frame with the door open but that doesn’t seem to be an option with out more components.
Thanks for you time .

Is there a possibilty to use HOLD, and connect the door to it?

Hi Thanks all for replies.
I solved the problem by making a single circuit of the chiller and the door interlock and connecting it t0 ground and WP. Works nicely now
