After successfully building a ~2’x2’ MPCNC I decided I wanted a bigger cutting area and built-in vaccum routing, so I started on a 4’x8’ lowrider. I printed a bunch of 3D parts, used my MPCNC to cut the flat parts, bought all the bolts/rails/bearings, then started on a 4x8 table. I only have a few hours/week to do this stuff, so the table took months, and in that time LR3 came out.
I did some searching and it sounds like some people have built and used both versions. I also saw some talk of a 2-3 upgrade kit, but I looked in the V1 shop and didn’t see it.
The advice I’m looking for is: should I finish my LR2 and just use that for a while, or should I scrap my existing stuff and to go an LR3? Has anyone done a parts comparison for the purchased parts (rail, bearings, screw count/type, etc) to see what the cost delta is for going from 2-3 if you reuse most of those parts? Is the accuracy provided by the extra rigidity in LR3 substantial enough to make it worth buying all the new parts?
I don’t have a ton of extra money to spend on this kind of thing, and I think I’ve pretty much bought all the purchasable parts for the LR2. I’m tempted to just finish the LR2 build, but it’s a lot of time and effort to put into that if I’m going to discover that I need to move to LR3 solve some super annoying problem (which I assume was the driving force for coming out with a new LR version).
Thanks in advance for your advice.
