A anycubic i3 mega
has 5cm less on the buildplate.

And a bowden setup.
TPU should be challenging

Build a dolly but do it better- buy an aluminium frame and don’t get ramps and arduino, get MKS base or mks gen instead.

ramps and arduino is not so bad when using 24V

Aside from that you have to modify it to work, and probably upgrade the voltage regulator.

An mks gen is just an all in one ramps that works on 24v out of the box, and has an extra mosfet.

Seconded, I've switched to MKS Gen and 24v power for everything and I'm never looking back. Besides the technical benefits it's also a WAY easier board to physically work with, being far less of a crowded mess than a RAMPS shield. The XH connectors on the MKS Gen are also superior in every way to dupont connectors on RAMPS/Arduino. The only slight hassles I've found are only having one Z driver (so need to wire Z motors in series if you're using two) and the LCD connectors on every one I've bought are upside down so you have to cut the tab off the aux cable to install them correctly.

Not 5cm less than an A8 he was considering.

True. But if I'm honest, my direct drive MK2s cant really do TPU either.

Anyway, there is no printer that will do everything for everyone and cost next to nothing. Ive read a lot of complaints about the A8, so Im offering an alternative that IMO is well worth its price. Im not saying its the best solution for everyone.

Nice. I didn't see that this had replies. I posted a while back. I just made another posts talking about which parts to buy better lol. I literally just bought my ramps and arduino an hour ago. I wanted to get something better but wasn't sure what or how it would fit in. Ive heard a bunch of bad things about ramps. Definitely new to the 3d printer scene. I've heard about smoothie board but haven't heard about mks? Oh well, i can save the arduino and ramps for another project. It was only 20$ with an LCD screen and few other things. So what would be best in your opinion? And would i need to buy any other parts to make it work and be compatible?

Best board you can currently get is a duet. Pricey though. 32 bit.

Smoothieboard is good but inferior to duet for a variety of reasons. (32 bit too)

RAMBo is premium 8 bit, marlin compatible. Expensive.

Best of the bargain basement (8 bit) stuff is MKS Gen (takes plug in polulu stepper drivers) or MKS Base (which has integrated DRV8825s and is a bit smaller), but otherwise is more or less the same as the GEN. Either would be fine. They are both cloned a lot though, try and get a genuine MKS one. They are about $30 from the usual places.

Nice. Thanks. I'll probably go the mks route then. I've already got all my a4988s lol. I've never heard of the polulu drivers. I may get an mks base then since the drivers are built in. Does it still need to run through an arduino or no?

The little plug in boards *are* polulu drivers, it's a sort of standard. You can use them on an MKS Gen. Or get a Base (don't get the SBASE though, that's a clone of a smoothieboard).

The great thing about these boards is that they are all-in-one - basically a ramps and and arduino mega, all on one board. You just need to plug in your wires and go. Endstops, thermistors and stepper connectord are all JST-XH so you probably want to get some of those, but at a push standard dupont connectors will actually fit.
