brand new Snapmaker ray out of the box. updated to latest firmware.
homes correctly to top left. but when I start to cut its all inverted. I have changed the origin and just makes things worse.
the x axis is running as normal but the y axis is running inviter into the negatives.
I have edited the machine setting to invert and got the x and y running in the correct orientation but hit start and the laser shoots to the other side and smacks into the wall. I have gone over every single post for the last 2 days and at a total loss.
When you use the jogging controls in Move window, does the laser move in the correct directions? Left moves left, right moves right, up moves up, and down moves down?
Can you provide the following:

I didn’t realize Snapmaker made GRBL based machines.
In terms of the design, that’s kind of a worse case scenario design to determine part orientation issues.
First things first, correct the jogging issue.
Go to “Y Direction Pin ($3)” and set to True. This will cause homing to go in the wrong direction. So to then correct homing toggle “Y Homing Direction Invert ($23)” to True.
Once done, home the machine.
Then create a letter “G” and engrave it onto some scrap material. I’m going to guess that the letter will be flipped vertically. If so, go to Edit->Device Settings and change Origin position to bottom-left. If not, take a photo of the resulting burn in the orientation that it was burned and include in a reply.
I suggest you switch to “Absolute Coords” as the Start From mode if you’re new to this. Home before each session and move the laser with the jogging controls exclusively, do not move the laser head by hand.
if you look at the cross hair on the left on the full screen that is the laser location in relation to the work area in light burn. it was homing correctly before the changes but wont now. and now running those commands just drives the laser into the front left corner. I’m not totally new I have been running a snap maker 2 on light burn for a year.
Okay. Let’s assume for the moment that jogging controls work correctly. I don’t understand why homing wouldn’t have also been inverted but let’s set it back.
Can you run this in Console? The second command will home the machine so be prepared for it. Stop the machine if it heads in the wrong direction.
$23=1
$H
Assuming the machine homes correctly, check jogging direction.
Then run the G test. What are the results?
Hopefully we get this sorted quickly and get you to bed soon.
Something is odd indeed. Did you actually write the changes to the controller after you inverted them? Don’t change anything in Machine Settings but curious what’s going on.
G-code motion target exceeds machine travel. Machine position safely retained. Alarm may be unlocked. (Right-click the ‘Devices’ button to reset the connection)
