Hi,
first post here, I've been lurking a while... I am building and designing-on-the-go a 3D printer with a workspace of 400x400 bed, 200mm Z axis. The bed will move up and down like with a core XY, X and Y axis on top of the machine. I am in doubt about the drive of the X and Y axis. I have found the CoreXY drive system, but I could also drive the X axis with it's own motor traveling with the Y axis. This would make the set-up easier I think. The downside would be the weight to be moved. But the weight is already considerable for a 400mm trave x-axis, adding a little motor and a lot less belt I don't think would matter much. I think I would gain a lot more from using 12mm aluminium rods for my Igus bearings instead of the heavy hardened steel ones I have now. But all this is just my thoughts, not based on any experience. Please advise from experience.
Cheers,
Hugo

For info, my Core XY has a build area a tad under 400 x 400 and 740 in Z. The main frame is 600 x 600 x 1,000. I can print stuff like this [www.youtube.com] and this [www.youtube.com] and there are some other things on my Youtube channel. The bed weighs in at around 7kg (10mm thick aluminium topped with 6mm thick float glass) and is lifted by 3 screws driven by a single Nema 17 via a continuous belt. As configured in the videos, the Y axis including the X axis weighed in at 1,900 gms and I regularly print at 90mm/sec. All belts are 6mm gt2 - never a problem.

Thanks for all the input. I've just bought aluminium rods instead of the steel ones for the moving X axle, reducing weight considerably. To keep things simple, I plan to use these:
Any comments? I like it to be spring loaded as it keeps tenstion, but I wonder if it is stiff enough.
Cheers,
Hugo
