I am new to Lightburn using a Genmitsu 3180 Prover. and running GRBL 1.1. When I load a file with a small graphic and attempt to run it, I get a “G-code motion target exceeds machine travel. Machine position safely retained. Alarm may be unlocked. (Right-click the ‘Devices’ button to reset the connection)” I get the same message if I use the laser pointing tool and probe anywhere on the workspace.
I have attached a screenshot and a copy of the current GRBL
I have read those thorougly and made sure the GRBL settings are as specified in the document. s for the third question, when I use the tool icon shown as " Set laser position by clicking on the page" my expected results would be that the laser moves to the specified position. Instead, I get no movement and in the console it shows the message referenced earlier.
1.The machine does have have limit switches and they are enabled. I have both software and hardware limits option turned on in Lightscribe as well.
2 The machine homes to bottom left.
3. When the screenshot was taken, the laser was at home position, bottom left
The problem with the offset is, the machine does THINK it has to move though negative X and Y coordenates to arive to the start point. This on its own WILl trigger a Alarm 2
At least does on ortur, but again this machine might have the offset on purpuse as a tool offset, ence why i am being careful on giving instructions
I see what you are suggesting, just not sure how to address it. The screenshot does show negative positions on home. As to Jack’s question on workspace size, I got that from a Robert Bland article re the Genmitsu Prover 3018 setup. I found it odd as well, but used it. Changing it back to 300 x 180 does not seem to affect my current issue.
Have you sent it “G0 X0 Y0” telling it to go to 0, 0?
Might see if it likes that after it has done a reset.
Have you tried the ‘clear origin’ and ‘set origin’ options?
Have you tried to ‘move’ goofy to the lower left, near home, and start the engraving from there?
Can manually move the head via lightburn ‘move’ tab?
Might let us know what happens to the X coordinates, increase or decrease when you move it right or left? Same with Y, increase or decrease forward and back. I’m just trying to verify that it’s operating in the proper quadrant.
Just ordered this to fool around with. It’ll be number 3… All of mine power up and read 0, 0, 0 when you click on ‘get position’.
That seemed to resolve it. After entering the command it showed x as 1.5 and y as 1.5 which is the same as the offset I have for the limit switches. Bad news however, is immediately after seeing this I went to my machine settings to check this and and get a communication with controller failed message. I notice as well that in the laser tab, it shows Busy with a 100% value. Wondering if I don’t have another issue, possibly with the controller board? At this point, the system is totally unresponsive.
That’s very odd timing. Was this accompanied with any dramatics? Sparks or smoke or anything?
It may come to that but I don’t think anything we saw earlier would have indicated that you were actively having a problem with this.
Try shutting down the machine and your computer. Unplug the machine from mains power. Try starting back up and see if anything changes. Try another USB port on your computer if you have one. Any change in behavior?
