I have a K40 and I opened up the engraving cutting area to 10" x 8", added a cohesion3D mini board, made my own X adjustable bed, and made a new control panel face. By increasing the cutting area found out the intensity of the laser varies quite a bit. Came to the forum and was directed to a paper on how to align the mirrors. It was a very helpful guide on mirror alignment While doing the mirror alignment cracked 2 of the mirrors "1 & "2. Bought the moly mirrors to replace the mirrors that came with the K40. Installed the new mirrors and continued with the alignment. I did a lot of shimming and elongation of mounting holes for the gantry. I spent a better part of a day aligning; tightening bolts, making shims, untightening bolts and making new shims. It’s not perfect but it’s better than it was. My next project is building a water chiller.
My 1 yr old K40 was working fine… until the desktop died.
NOW … I re-installed software on laptop , and XY are reversed. I THOUGHT I had good knowledge of the setup , but apparently NOT !
I re-entered the ID and the BOARD # … but COREL-LASER just will not change the XY.
