Well now you just hit on the downside of larger tubes…larger footprint, and slightly longer print times.
I think what you just said was good stuff?? Lol
I’m just shooting for a cheaper, sturdier, half-sheet machine, with the accuracy that the mpcnc can deliver.
Boom, already done. May I present, the Lowrider CNC!!!
At a half sheet, the LR is by far the best way to go. I have a 1/4 sheet LR, because I feel that and MPCNC can’t come close at that size…but I have not tested that.
I’m not trying to force you to do anything. I just wanted to put my build plans in for consideration, cuz not making a 23.5mm version available means I need to update my plans.
I don’t plan on cutting anything tougher than hardwood, and I did plan on adding midspan supports to the long axis. The main reason I’m planning a 36x18" build is that I want to be able to carve the top of a custom coffee table with it in one operation. I really don’t want to futz with repositioning the workpiece and aligning everything for a second pass, because that way Murphy lies.
I really should have started with a LowRider, huh?
I’m still making a Primo either way, I just might make the MPCNC 18" square instead.
Guess I need to get some video going on my 1/4 sheet primo. Now that I have a technique for panel gluing that seems to work…
It just means you would need 1" EMT, if I go that way. Making a 3/4" version instead of a 1" just because you already bought the EMT seems a little unfair to everyone else right? I am not going to design and maintain 4 versions.
Of course. It seemed to me like the 23.5mm version was a foregone conclusion until recently, but if bumping up the EMT a size improves the quality of the machine, it’s hard to complain about that!
I was about to say I’d just make a LowRider with the 23.5mm that I already have, but that’s doesn’t appear to be an option. Any suggestions on what to make with it?
It’s worth noting, I’m still spending less than half the cost of the DOM, even buying the EMT twice!
I feel like it’s worth it for me to return or take a hit on 3/4" conduit in favor of the 1" conduit.
The reason why I like the MPCNC design over others, is the ability to switch out the conduit with longer conduit to increase it’s footprint. Right now I don’t have much space but in the future, all I need to go bigger is more cheapo conduit.
If 1" conduit means I can scale to 4’x4’ while still being reasonably ridged and cheap, then that’s a huge bonus. I completely understand why you’d want to consider this change.
This was in another thread…
I tried to build an MPCNC Burly that had a 2’x4’ work area (I wanted to be able to do quarter sheets of plywood; the entire machine footprint was 24"x58"), and it was no good. Even after adding midspan supports the Z axis has about a quarter inch of play. A 4’x4’ work area is decidedly the domain of the LowRider; no amount of additional support is going to get you a working MPCNC at that size. From everything I’ve read, you max out the MPCNC at 3’ on one side. Even then you have to have a more reasonable size for the short axis, and the long axis is going to need supports. That was part of my reasoning behind making my Primo 36"x18", I’m maxxing out one side’s length while leaving the other small enough to be manageable.
If you really need the work area, I recommend buying two of all of the electronics and making a LowRider for your big jobs.
Nice find! I’m going to have to make some shelving with the spare conduit now…
Just making sure we are on the same page here, I don’t want it to seem like I am changing it just for the fun of it.
Lots of uses for conduit if you can’t return it. Lots of guys are 3d printing endcaps and using it is shop handles, the maker pipe Tony linked, I have a piece as a sledge handle, you can always make a burly with it, I even have parts you can print similar to maker pipe I use to make rolling workstations with on thingiverse.
Well, @vicious1 found it. I just remembered where he put the thing…
To quote Venom: “Pussy”
Home Depot in Canada sells Columbia branded emt conduit made in the US. sizes are 1/2", 3/4", 1", 1.5" and 2" so I think its safe to assume a north american standard.
I originally planned on only making two, but DOM is still a bit too expensive.
With 4 my basement would be full so now it will be 1 in SS and 1 in emt and a soon to be low rider unless there is a update in the pipe low rider
By the way can you please design ZenXY with 1/2" EMT? Thanks.
I’m holding out for the pool noodle version…
