This is my first post into this forum. I realy like the lightburn software let me say this at first. I’m using this software for about 2 years now. My problem is the focus sensor does not work. I’m struggling with this already a long time. What is working.:
Afcourse focus sensor is mounted. Hardware is working . I’ve got a ruida RD6445 controller board. I can see the led come up on the controller. The z-limit switch is also attached to the same input.
Initialising of the z-axis is working. If it see the z-limmit or focus sensor it wil stop on these. Adjust it with the offset written in the machine setting. So basicly i can focus by starting up initialising z-axis.
The strange part is it doies not startup when prseeing the focus button on the main panel or the lightburn button. Yes the z-axis is enabled.
As i’m saying i do a focus by homing the z-axis.
This is my second machine . The first machine i have had was the same setup . Same ruida contoller RD6445. This machine did not have this strange behaviour.
I had long conversations with the supllier of Ruida controller and they could not help me.
Does anybody have a clue or direction to seek ?
I’d be happy if there where a button in Lightburm to home z-axis. This would help me a lot for now.
That sounds ok. Could you please suplly me this working firmware. I’m thinking it has to do something with that. I will check youre suggestion. I asked for other firmware to Ruida they do not respond to this
That was it great. I’m very happy. This fixed the problem. It is working now. I have had a lot of talk with the supllier and manufacture they refused to give me a firmware. They did not know about this bug.
Sorry, I was in a longer than expected meeting. I can see from the thread you got focus to work.
I will say it appears you had it set wrong. That’s what I meant when I said the setting is not intuitive. This is the proper setting on my 6445 in order to enable the focus feature (Enable focus: No):
