Hello guys, this is my first post and I’ve got a problem.
Keep in mind that i’m a newbie.
So the problem: I bought a VigoEngraver VG-L7: at the beginning all works fine but now I saw that when engraving the text is not really defined as you can see from the image below.
I tried to change the motion parameter but nothing change: I don’t understand if the problem is the laser itself or the motion.
Can you please help me? Thank you really much
Simple things first: Check for wobble on the carriages that move the X-axis and the laser head.
I have a VG-L7X which is very similar to the L7. I was printing trapeziums when the model is rectangular.
The culprit was a wobbly Y axis, fixed by fitting acentric spacers for the screws on the rollers that support the x-axis arm. I have been printing perfect rectangles ever since ;-). If the laser head carriage wobbles as well, you might like to put acentric spacers on that as well, although I’m not sure that that is as critical.
Great that you found the problem. I still suggest fitting acentric spacers like the ones shown in Don’s post to remove any “wobble” in the x or y carriage. They only cost a few $ for a packet of 10 and will prevent any future problems with inaccuracy in the etchings.
