Hi,

Currently building this out of an old K40 case, just wondering what bearing was used in the printed bearing holder?

 

Hi,

I encountered the same obstacle. I have everything bought and mounted except the bearing that is supposed to go into the bearing holder. I could not figure it out from the pictures either on replicantfx.com. Has anyone completed this build and/or has information and details on said piece of the build? Thanks.

 

Thanks for your post. I have ordered a 5/16 by 7/8 bearing. Hope it works.

 

I believe they are using the 608ZZ 8x22 mm 608Z Metric Ball Bearing. Or 608 for short.

 

Quick question.
What kind of 20 toothed metal bearing can I use in the place of the 2 printable ones for the 5/16 shaft. Or what can I use to substitute those for metal ones. Im in the materials phase of rebuilding this except on "stilts" so I can operate a rotary and install a mechanical z bed. Ill also be moding the case if not trashing all together since it wont be quite deep enough. That or cut the bottom out to place on top a table with a square basin cut out if it to support this idea
Thanks

 

I'm now in the building phase. Ive decided to just trash the casing and go for 800x600mm. At this time I'm going to try the 3d printed pieces to see if I like the feel. If not I have a few backup options. Check this post out

Its a k40 laser enhancement group on Facebook that i joined. I decided to take the question there and see what other ideas were out there also. Theres some good advice here also mostly with the idea that you have

 

I am attempting this build but I have an issue. I dont see the bearings in the BOM that go in the bearing holder? Also are the V Bearings mentioned on the Y carriage are they the same same the V Wheels in the BOM?

Any luck on finding a metal toothed bearing?

 

Even at 2023 prices I'm looking at around £100 direct cost for the upgrade. Most of that is extrusion, a piece of mdf, some acrylic and a load of fittings. New mobo is not factored in, I had that to use on the K40 anyway.

If I buy a new laser head I'll be up to £150 in total. If I factored in the cost of the K40, less than £300*, I have paid £500 (including new mobo) for a 40w laser with a 410 x 640 cutting area. Another £100 will see an adjustable bed. I can't see a comparable machine, let alone a better machine, for less than twice that.

This, and others, are viable upgrades even if you buy a new K40, but there are loads of second hand ones on ebay anyway.

Mine is not an exact copy of this, it mixes and matches with some other builds.

*mine was free, the first one they sent was dented so they sent a second one and didn't want the first one back. It was fully functional and has been in use for almost two years.
