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)

$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.

I have an EleksMaker Mana SE v3.2.  I'm wondering if I can connect to D9 and GND using the header as shown in the pictures attached so I don't have to solder.  Thanks.

yes thats why they added the header so they could do a homing switch kit.  that would work just fine.  You do need to remember to turn it on in the firmware though

I'm so glad I can do that.  How do I turn it on in the firmware?

depends on the software you are using but it boils down to typing $ then 2 numbers then = and another number.  the list of $ values that need to change are discussed above in this thread.  you can see your current firmware values by typing $$

In T2Laser you can enable the switches from the settings menu on the laser controller screen, but how they function is largely determined by the firmware although there are some parameters you can change (such as homing direction, feed rates and pull off distances).
