You are correct, I was thinking it was like the others and used a bit mask.

So when the X-homes, it drives into the limit and then out, slowly back to trigger again and then jumps back to 0 - is that working correctly?

You may need to increase the pull-off distance (e.g. $27=2) to make sure it's clearing the switch.

The X will drive, bump the switch and back away a tad.   I did read about $5=1 that a power cycle might be required. Will have to test everything again later today. Thanks for you input.

It should then move back to the switch a 2nd time at the slower feed rate, if it doesn't it's not pulling off far enough or you are getting a bounce on the switch (increase the debounce setting).

$24=100.000 Homing feed, mm/min (100.000)
$25=1000.000 Homing seek, mm/min (1000.000)
$26=250 Homing debounce, milliseconds (250)
$27=1.000 Homing pull-off, mm (1.000)

Thank you.

$27=2 got both x and y to home.
$23=3 homes to bottom left corner.

All sorted, thanks for your help.

Once you get all moving in the right directions you can adjust those settings up a bit.

You can set the homing seek 4000. And the homing feed is safe at 400 to 500. Those will keep your accuracy while speeding up the homing.

I use even higher settings than those with no problems.

It looks like pawpaw's air assist, but doesn't have a fan mounted.

Air assist improves cutting (and may also help with engraving), this is a low pressure design using a fan and duct to clear smoke from the laser path. You can also use a compressor for high pressure air jet to clear the kerf and smoke, which is more effective when cutting.
