Hello, I have a TronXY clone from electronicgeek.com in Canada they call the Prusa Eg4XL. (Boy, that guy's name is over used!) It is a beefed up version of the large format TronXY. It has dual y rails and a 24v PSU with heated bed and a 300x300x380 build area. 330x330x400 is supposed to be obtainable.
The kits that are put out always seem to have issues whether buying from TronXY or another reseller. The heat bed is an issue on all of these machines. The wire simply taped to the bottom with masking tape as in this video and the loose bed was a let down. Some people use different bushings or print parts for upgrades that pull the wheels together from the underside but what I did to straighten and firm up the travel of the wobbly bed was a no cost, no added parts solution.
Simply remove all rollers, grab a rotary hand tool with an appropriate burr and cut the holes into an oblong shape toward the center of the bed. 1 to 2mm will be enough so you can do this with a round file. When you install the wheels again make sure they are in the groove of the 2020 aluminum extrusion and push toward middle as you tighten.
The wheels now push firmly against the rails and all is snug as a bug without suspending a penny. (No pennies in Canada now so insert "nickle" if you're Canuck!)
If you are worried about things coming loose; I like nylon inserted lock nuts or split washers but I have not found I need them. Yet.
This is a free and very effective fix if you dont want to run around trying to find eccentric bushings, etc.
Good luck!

Yeah nice invention. you should put large washers on acrylic (top and bottom) it helps stabilizing though
