Is it possible to make the body of a k40 deeper?

[Purplezebra (Vicki)]

Hi,

I own an omtech K40. I’m trying to engrave onto thicker items (currently boxes) that don’t physically fit into the space below the laser head. I’ve so far added air assist, removed the stock bed in favour of a Z-lift and pin bed, added a better (in-line) extractor, and I’ve just purchased a mini-gerbil to allow me to use lightburn. Just for background info.

I’m wondering if it’s possible to simply remove a section of the base to allow the items to sit on the table below? I’m struggling to work out what this would mean from a safety point of view. I’d purely be engraving, so cutting depth isn’t an issue, and the items I’d be using are max 200x300mm so fit the standard bed in that regard. They’re just too tall!

Any input would be very much appreciated. I’m still very new to it, though finally feel that I’m making progress and getting my head around things! I run a personalisation business so being able to engrave thicker items would be really useful. Everything I’m finding online is about increasing the standard bed area, I’m not coming across anything relating to the depth of the base.

Use V-slot extrusion to build extra box space under it?

I would like to cut out a section of the bottom of the K40

I would like to cut out a section of the bottom of the K40 to allow recessing in my rotary attachment to allow bigger diameter objects to be engraved. I want to make a set sheet metal sides to raise up the K40 to allow for this, what gauge sheet metal do you think I will need to support the weight of the K40? (I would make it out of one long piece folded at the corners with a top and bottom lip folded at a 90 degree angle)

heres an idea maybe its been thought of.

heres an idea maybe its been thought of. If i cut the bottom out of the K40 and attach a cutting bed the same size as the opening between the x and y rails and have it positioned under the machine so it can accommodate deeper objects? [2be2965d2323523664ac66f9919b809d.jpeg]

@Bill-CNC also did this along with a bunch of other changes:

(K40 Laser Cut Area Enlargement) High voltage wire and Flyback

Hey All, I have a question about the high voltage wire and the flyback. I am enlarging the K40s cutting area within the k40s eclosure, so I removed the electronics and its being put in its own enclosure. My problem is two things. 1). The high voltage wire has some chaffing where it comes out of the back of the PSU, due to the aluminum base is real rough. 2). The high voltage wire will now be to short so I bought 6 feet of new high voltage wire with connectors from amazon. I was originally go…

Many have cut out the bottom for just the reason you mentioned.

I made a box out of 3/4" (2cm) mdf as big as the body of the K40, then cut a hole through the K40 the size of the bed/working area. I think I added 8" (20cm) to the height. It works well.
