I pre-ordered an E2 which I received in November 2017, but due to life sometimes taking unexpected turns, it was only a few weeks ago that I finally had the opportunity to unpack it and start learning the ropes.
I installed the air assist unit, upgraded the firmware, installed LightBurn, followed the focus calibration wizard, and tried some test cuts with various materials.
Having read quite a few posts on this forum about power settings, cutting speeds, etc, I have to admit that I feel a bit disappointed with my own results. I’ll post them here hoping to get a second opinion if they are indeed unsatisfactory, or if i’ve just been expecting too much.
The first test cut is a 240 gsm, 0.3 mm craft paper. Top row was cut at 840 mm/min, then each consecutive row was cut 60 mm/min slower than the previous one. Please ignore the erroneous labels to the right - that was just me forgetting to change them when I changed the speeds in the project. Power increases from 10 % in the leftmost column to 100 % in the rightmost one. Squares have a side of 6 mm. The fastest speed at which an actual cut was achieved was 720 mm/min.
Looking at the picture up close, I notice that the engraved text (cut at 1800 mm/min and 80%) are very, very wobbly. Could this be caused by vibrations from the air assist compressor? My E2 does vibrate considerably while cutting.
Second test cut is 560 gsm, 1 mm cardboard. Top row was cut at 600 mm/min, then each consecutive row 60 mm/min slower. Power increases are the same as for the first cut. The fastest speed achieving a cut was 300 mm/min.
The third cut is a 1 mm, 3 layer birch plywood. The seller said that other customers have successfully used it for laser cutting projects, but he was not sure if they used diode or CO2 lasers. Top row cut at 600 mm/min, then each consecutive row 60 mm/min slower. The fastest speed achieving a cut was 60 mm/min. This is certainly a lot less than I expected, and it’s not a very clean cut. I did weigh the plywood piece down on the cutting mat in order to avoid problems caused by bent material.
I do understand that different qualities of plywood cut more or less well, but even with that in mind I have to admit that this last result made me feel a bit disheartened.
Here is where I reach out to you, fellow forum readers and E2 owners: Are the above results in line with what you would expect?
Your help and opinions are greatly appreciated.
