You can see my marks on the wood and the print has drifted down and across
Console output never report being shows every being near 80x80 or 100x100 when burning
Hope this is clearer, but the prints drifting for some reason
I have irregular shaped items and I want to guaranteed it prints in the spot I tell it to. I thought that Print & Cut was designed for this task (Kim and Garrett Make IT say the same thing)
The way the design is off from your targets appears like you may have a pointer offset enabled. Is that the case? Are you using the pointer to define the targets, or actually pulsing the laser at those points?
I was away for the weekend and responded from the campsite this morning. Let’s see if we can work together to get this sorted out.
If I understand correctly, your initial problem was a communication issue between your machine and Lightburn. You were using the wrong profile and that has been corrected. Your current issue is that the test square doesn’t engrave in the correct location according to the targets. Am I correct in my assessment?
If my understanding is correct, try a test for me and report the results. Draw a 100mm square and place the lower left corner at 10x, 10y on the lightburn screen. Make sure you are in absolute coordinates, home the machine, pulse the laser to make a mark at 0x, 0y, then engrave the square. Measure the square to verify if it is indeed 100x100 and also determine if the lower left corner is 10mm off the home point in both directions.
Do the testing on cardboard so you don’t waste good material.
Thanks for you reply. Spot on about the config and all working fine.
Can I just check what you mean by pulsing the laser. Is that turn it on manually to make a mark ? Thanks in advance.
I just looked up this machine. I didn’t realize this was a 3d printer with a laser module. Not sure how much, if any difference that makes, but I’m a firm believer in dedicated machines rather than multi-purpose machines like this. This is outside my experience level.
Except, at least when mounting a laser to a Spindle CNC thre are typically several setings that need to be changed between modes / operations. Not something I’m familiar with.
Tried the CNC switch and it didn’t make any difference.
Switched on the Enable Pointer Offset and set to -5 x 8.5 which is what the offset was when it tried to print and is wasnt aligned. That worked!!! Out by a mm but that might of been me lining up the laser when setting the target points.
The way I worked out the offset was I printed a square separately which would be my target, then turn off the square (output) went back to my original shape and switched on again (Output) , set 1st & 2nd targets to the orginal shape Let it print. Measured the difference and entered into Offset .
I just need to remember to do that on P&C and then switch off.
