As in this episode we will be discussing how to “square” the K40/ eBay Chinese CO2 Laser Cutter & Engraver to improve the performance over a greater cutting area.
Worth note is paying attention to the titling in the video as after producing it I discovered that sheet metal was also out of square by as much the 1/8th inch the gantry was off leading to around 1/4 inch over all error from corner to corner.
To correct this I also had to replace the 3/8th inch bolts of the gantry and replaced them with #8 bolts and washers to cover the 3/8 inch holes. This gave me the extra wiggle room I needed to move the gantry the distances I need without re-drilling the holes and while I would suggest shipping the unit with #8 bolts it does a fine job of holding everything into place for standard duty use.
Also please keep checking back the resource link as I have a number of updates pending…
