I am trying to use print and cut to align something larger than my bed can handle. I am following the guide exactly but when I go to realign the project to the registry marks it’s all kinds of off. No matter how I readjust or redo the markings it just is off by a lot. I have had this issue with just using it for one simple page as well. I do have an offset laser which is correctly calibrated, but this is just causing me to waste materials because it will not align to the marks.
I just read in the article that it says that the laser needs to be properly homed. My laser is not capable of automatically doing this and with the laser offset I am not sure how that works. Anybody have any suggestions on how to properly home a device that does not have automatic homing?
I have been homing the laser to 0,0 using the comands to set it and turned off the offset laser. I am still having things not line up perfectly it’s slightly off. I just can’t seem to figure out what’s going on.
This is my latest attempt it’s still not lining up as you can see. Also when I tell it to go back to origin it doesn’t actually go back to 0,0 , but when I read position it says 0,0. I went ahead and moved it back reset with the G92 X0 Y0 command and it goes back to the position it did earlier which wasn’t the machine origin. I am going to try to realign the laser offset see if that’s my issue
It is possible the laser head moves slightly when sitting idle. To confirm this can happen, a few seconds after commanding a move, see if you can move it by hand with the power still on.
If you can move it at all, try this. In the console window, enter $1=255.
If it is pretty solid and you cannot move it, you might research adding limit switches to your machine.
