Large printer build:
I need a printer with 1m by 1m by 1m build volume. Did somebody tweak a TronXY or a CR-10 to reach this goal?

The only reason the Tronxy X5S makes sense for me (barely, from a financial point of view) is that I’m not changing the build volume. I’ll end up keeping the frame, steppers, bed supports, Z system (except switching out the lead screws), drag chain (probably), at least for a while the belts, and maybe the power supply if I don’t go entirely to 24V (right now I have both 12V and 24V and a separate MOSFET for the badly warped bed). For me it was a bootstrap aid to building essentially my own printer, and I’m only partway through that journey.
If you go to a cubic meter of build volume, you will also throw out the frame, bed supports, and belts for sure.
It’s a really crazy expensive way to buy five stepper motors, a bad electronics combo with only four stepper drivers, and some Z parts. Also, Tronxy refuses to release source code for their Marlin build (though GearBest will provide it for you if you buy it through them), which would matter more if it weren’t such a terrible hack of Merlin or if the electronics weren’t throwaway junk that you’ll end up outright replacing anyway. 
I’ve been recording my explorations of the Tronxy X5S at https://plus.google.com/+MichaelKJohnson/posts/jCYcEu7SHiD generally.
It was already cheaper …

The Tronxy style frame at that size is going to be too weak. You may be better off designing your own.
Nobody going to mention how the Voroni egg is miraculously sticking to the print bed using only one point? 
Oh god a meter bedflinger is a terrible idea.
I don’t think it makes sense to scale up any of these designs to that size without seriously reworking the design.
@Jeff_DeMaagd @shauki @Adam_Steinmark @mcdanlj Thank you for your feedback. 
I think I will drop that idea of scaling up the build area and try to split the model.
I don’t think having a large printer is bad if you really need it. You just have to live with it being heavy and slow, or use expensive parts to help with at least some of the weight.
Which means you’ll need to have it as a secondary printer for your larger projects. Which again makes glue and screw a rather neat alternative whenever possible, yes.
I should clarify. A large scale printer is not a bad idea in itself, but it brings its own headaches. I just don’t think a design that’s good for 300mm will work well at 1m without serious adaptation work.
If you can rework the models, that might be the better way to go.
@shauki I have thought of the same. It’s more cable to drag along, but not much worse.
You can also make the frame stiffer by bolting metal plates onto it, which is part of the way towards a heated build chamber. But we’re seriously going into the realm of custom builds here, and I kind of didn’t want to nerd about it.
@mcdanlj I just realised that the TronXY is “limitted” to 300 by 300mm build size. So in this case I prefere the CR-10.
