From some week when I start the autofocus macro the laser I think goes to down because it’s start to move up all the frame, do you have any idea or settings that I need to modify?
It’s strange because I didn’t modify anything in settings.
I’m using a Twooatrees TS2
Thanks!
You´re asking him to go down and focus the move is ok the function don´t, check if your auto-focus sensor is working fine clean dust contacts.
Thanks for the reply. Do you have any suggestions to check the autofocus working fine?
Did you create your device by importing a TS2.lbdev from web or TF-card?
Previously from TF-Card and after from web but the problem is the same. I’m trying to cut 4mm and my macro is this:
$HZ
G91
G1 Z-2 F300
I’ve checked the cable for Z axis and also others but seems ok.
And autofocus for engrave is OK?
If you type in console $HZ and press enter where does laser head moves? and stop at limit switch?
Already with the homing $HZ cause me the problem.
I did a video here:
Post your TS2 engraver.lbdev.
Do you hear a click at the end when laser goes down? Your laser Z limit switch are in the top or bottom?
If top try reverse Z.
Did you change some GRBL settings? Maybe your (Z) Home direction is incorrect.
I’ve just tried and no changes, it’s still unfortunately does the same thing
Type $$ and press enter in Lightburn console window and post here the output.

Did you change any GRBL settings? $130 and $131 and others?
If you press the focus pin do you hear a click?
Jog your laser head by hand to the middle of the Z axis then issue in console window G1 Z2. Does the laser move up or down?
If this guide helps:
https://wiki.twotrees3d.com/en/LaserEngravingMachine/TS220W/MachineCalibrationGuidelines
Also make sure the pin touches the material and not a void when auto-focus.
Report back.
Thanks Parsec,
No I didn’t change any settings from what I loaded, don’t know why there is 451mm instead of 401mm. The Z travel max is set to 63mm, I’ve tried to lower it but same results.
No I can’t anything, here a small video:

Move up
2.Your video is not public.
3.It´s standard configuration.
Maybe you have a faulty switch.
Try now for the video
Do you have a voltmeter to check continuity/Ohms at the plug on the end of the cord that comes from the switch or at the switch?
Also you can do a ramp test and focus manually.
