I have a jig template set up on the Xtool D1 pro 20 watt and here is what happens when I use it. This template
is set to run six coasters at a time. Before I start Lightburn, I move the laser head to the upper left corner. Then
start Lightburn and connect. At this point the laser head moves about a quarter of an inch, homes and all is fine.
I can frame each of the coasters with the round frame button to check alignment. Then I set the laser power to 2
just to run. Each coaster completes it’s cycle the laser returns home. Works great, but here is the problem. If I stop
the engrave in the middle of a coaster cycle, then hit the home button, the laser head moves to the far left side
and crashes up against the rail. Has anyone had this happen to you? The coaster template is aligned to the legs
of the Xtool. Iuse the Xpos and Ypos to set the first coaster location, the the array for the rest of the coasters.

Is there a reason you have to move the laser to the corner before starting the laser? Does homing not work reliably if you don’t do this?
How are you doing this?
How are you stopping the job? If you’re stopping the job with the stop button try pushing pause first, then stop. After that try homing, do you get the same problem?
Is this a generalized problem? If you run part of any job and stop the job, then home does this occur?
This problem is a bit unusual. I would expect homing to function correctly under pretty much any circumstance and not crash. Somehow it seems like for some reason the homing behavior isn’t working under a specific condition. My first instinct is that this is a firmware bug given xTool’s track record but I haven’t seen anyone else mention this. Granted the conditions are unique enough where others may just not have run into it.
Thanks PY for your quick response. If the laser is about 5 inches each way in X and Y away from the origin,
and I press the home button, it first moves in the left X direction until it crashes against the frame and sets there and grinds
with no movement in the Y direction. Then I turn the machine off and turn off Lightburn. After this, I move the laser
to the upper left corner, restart the machine first and then restart Lightburn. Press home and the laser move about 1/4
inch in each direction in the origin area and all is fine. When I frame the part, the cross hairs show where they need to be.
Then before I engrave the part, I set the cut layer power to just 2 percent so I can see the engrave outline. After this the
laser will return to home after each run.
When I start the engrave and press the pause button, nothing happens and the laser continues to move. Then I press stop,
and the home button and it will crash as described above. This is in absolute coordinates. I can move the part away from the
original location and it run fine and return to the home position. But when I stop the part in this new location and press home,
it will crash again as above. Also, this is with the extension kit and the table setup size was entered as instructions.
Is there away in Lightburn to see where the X and Y position is after homing? Where the X and Y actually is?

Seems to me you have a generalized problem with homing unrelated to your template setup.
Is the laser able to actuate the limit switch specifically on the left side? Try 2 tests:
with the machine off, manually move the laser head to the left of the machine. Can you physically hear and see that the X-axis limit switch is being actuated?
with the machine off, move the laser head to the middle of the machine. Then turn on and attempt to home. Manually actuate the X and Y limit switches manually. Does this stop motion in that direction? Technically you’ll need to do this twice in series to complete the homing operation.
It may be a situation where the laser module is positioned in a way where it’s preventing the switch from being actuated. Try to determine what’s causing that scenario.
Your machine is set to make your post homing position 0,0. You can confirm this by issuing ? in Console or by pushing the “Get Position” button in Move window. Note that 0,0 is not an absolute position in physical space. It’s simply the assigned coordinates for the post homing position. If for some reason homing occurred at a different location your laser would still consider that location as 0,0.
Thanks PY I tried manually moving and powered on to move laser home with the laser in the middle
of the table. I noticed on the Ortur, the bottom lower left limit switch has the little bracket that triggers
on the carriage and always returns home. On the Xtool D1 Pro 20 watt there are little horeshoe shaped
brackets mounted on the carriage with L shape brackets that go inside these horseshoe shaped swithces.
I noticed this also, on the regular Xtool d1 10 watt, when I turn it on and press the home button, it will go to the
home position. When I go to the move window and jog the laser out in the center and then press the home
button IN THE move window it will return to the home position. But this will not happen with the Xtool D1 Pro 20 watt.
It crashes straight into home side rail. This is all in absolute coordinate origin on th Pro 20 watt. I see no cables or anything
in the way. The table size is X17.008 x Y36.850 in Divice Settings. On the regular Xtool there is no limit switches.
I guess it would be nice to figure out a way to always have this laser home to 1 inch away from X and Y from the far left
corner and always return to that same position after a job is done to keep carriage away from the switches.
As always thanks for all the help and sorry for all the bad questions. Maybe it is something easy, I just can’t
figure it out.

These are the limit switches. I looked up what these look like on the Pro and looks like these are not mechanical switches but rather either proximity or optical switches which may make it a little trickier to manually trigger.
The non-Pro D1 does not have limit switches and relies on a sensorless homing method that people had mixed results with.
Functionally it should work this way. Something is not working correctly with the limit switches.
Check out these pages from xTool that cover installation and troubleshooting for the switches. There’s likely something either mechanically or electrically not setup correctly.
