I just put extensions on, after not using it for a while. Laser will not move left or right, only up and down. I’m not sure if I need to calibrate it, or something. Thinking about just taking the extensions off at this point.
What have you done to accommodate the larger size?
When you say laser will not move left and right, are you doing this with jog control? Is there any motion or noise at all or nothing?
If nothing, this likely has nothing to do with your extension. There’s likely something not fully plugged in.
Do jog controls work correctly for up and down? Do they move in the right direction?
Check all your connections and retry.
Hi. Thanks for replying. All I did to accommodate the larger size was extend the y axis to what tool recommended. 860 cm.
I triple checked that I put the wires in the right place. I took a picture the last time I opened it. I can include it if you want.
The y axis does move on the jog controller fine. The placement of the laser is obviously way off in light burn.
The x axis does move, but I can push only one movement to the center with the movement window on light burn. If I press do it again. It makes a violent clicking sound, and tries to force it’s way over an invisible point.
On light burn I can make the laser go way off the grid. I have to zoom right out to even see where the laser is.
I can take a picture of that too if you want.
I’m not 100% sure it’s going in the right direction. As it’s not so easy to know what is supposed to be up and down. When I push on the directional up arrow key (above the home button). The laser moves to the bottom of the light burn screen. (towards 0.0). When I push the directional left arrow key (left of home). It moves away from 0.0.
I should of done a few prints before I put the extensions on. Just to dust the cobwebs off. As I couldn’t use it until I fixed a ventilation system.
I put allot of effort to built lt a really nice extended enclosure, and it’s breaking my heart…and my balls 
I’m an idiot. It is going in the wrong direction.
Which tool? And what specifically did you do?
Can you confirm this is correct and not 860 mm?
Can you confirm whether or not you have homing switches on your laser?
To which direction does the laser move when homing?
I would consider this backwards. Up should move the head up toward the top of the laser.
I’m confused by this. I thought you said left and right didn’t move the laser.
Okay. Thanks for confirming.
Are you certain that you’ve plugged the cables in the right orienation? Make sure that they are not inverted.
Can you provide the following?
- screenshot of Device Settings
- run these commands in Console and return output:
$I
$$
$#
?
Do you need me to plug in the x20 when I run the commands?
Do I just copy and paste the whole thing? or just one line at a time.

I just want you to know. I really appreciate all the help.
Check on the motor side as well. Make sure the connectors are not inverted. Unless you made a configuration change these motors shouldn’t be inverting direction. Are these new cables provided with the extension? Can you confirm if this is a factory extension or a 3rd party extension?
I can’t see much in that photo to make out anything.
Yes. The controller is what will be responding.
One at a time is more reliable.
Note that what you’ve sent so far is the output of just the first command. Looks like the next 3 are not acknowledged.
Ahh ok. I’ll get on it

I doubt it’s third party, but I’m not sure. It shouldn’t be I bought it all at the same time as a pack…From aliexpress though
The motor is on the right way. I’m not entirely sure how to check if it’s inverted.
Okay. One command still missing:
$$
Can you confirm if your machine has homing switches?
The connectors are typically keyed so if you didn’t plug them in backwards you should be okay.
If you’re absolutely certain they’re correct then we can deal with it but you’ll likely end up with a different controller configuration than other “stock” systems.
Hi 
It seems I accidentally over-exceeded my allotment of 22 messages. I can understand why it’s in place. If I knew I would of been a bit more frugal. I put the last command in.

Let’s first get your jogging controls working in the correct direction.
Can you run this in Console:
$3=3
That will invert the direction of X and Y. Check your jogging controls. Do they now work in the correct direction? If not, what’s doing what?
If things are normal, attempt to home the machine. Does the head move toward the switches?
If so, check position. Is it 0,0?
Hei Sorry. Still It didn’t work. I’ll unplug all the external connections and plug it all back in, and then I’ll write all those commands back in.
I think it’s hitting the limit switches, but I can’t be sure. I still can’t move the x axis more than 1 cm, and it still doesn’t like going to the back of the frame (past about the 55 cm mark.)
If it doesn’t work. I’ll take a few pictures and screenshots, because I’m not entirely satisfied of my description of my problems. I’ll do my best to be more assiduous and clear.
I’ll have a bit more time to tackle the task during the weekend.
I’m think it’s something simple, and I haven’t given you a clear enough picture of what is wrong.
This will require an additional change. Forgot that your original problem started with the extension.
Make this change:
$131=850
You need to also adjust LightBurn height in Edit->Device Settings.
Can’t comment on the other issues you listed.
As you’re reviewing this weekend here are some things I’d like you to validate:
- Jogging control direction. Are all buttons working accordingly?
- Homing direction. Is the laser homing in the expected direction?
- X/Y calibration. If you ask the laser to move 10mm in each direction, do you actually get 10mm of movement?
- Homing success. Does the machine home correctly? What are the coordinates after homing?
The settings $130 and $131 are the travel lengths of the X and Y axis respectively. If you made it 850mm long in the Y, you’d need to set $131=850 for the machine to know how far it is allowed to move.
