Hi
I am trying to understand the cutting speeds and Laser diode power.
I have a Sculpfun 9 and have cut many pieces of 3mm MDF at a speed of 300 mm/m at an intensity of 80%.
I then tried to make a jigsaw puzzle. I stuck the picture onto the mdf using a spray adhesive. I used exactly the same settings and it did not cut through.
the only addition is a piece of paper glued onto the MDF
At a guess the answer is the glue. Always best to do a test in situations like this. The glue used in plywood has a drastic effect on the cutting and could well be the same when applied to paper and MDF. Don’t seem possible, but some glue is very hard to cut through.
Thank you, Let me give it a try by changing the settings and I will let you know my results
Additionally, the lighter the material, the harder to cut. Therefore, a white sheet of paper might be harder to cut than a black material that is 1 mm thick. The more energy gets reflected, the less impact during lasering.
Thank you for your feed back. I have managed to cut it out. The Glue and paper were the biggest problem and once through that everything did go smoothly. I reduced the power and speed and increased the number of passes. This worked for me.
