My hbot gslot have an update and lose torsion .
Mount square belt and carriage are really simple and need around 10/15min . That are my objectives on this built have fast mount xy module.
Now need change z system and try it soon 
increasing some space in z and in y.
H-bot with v-wheels is going to rack like crazy. You should convert it to CoreXY now and save yourself a lot of pain.
Ryan you check a video? …no pain
HBot is terrible without an extremely rigid bridge or very low speeds, as soon as you start printing circles you’ll see it.
@Nathan_Walkner orrrrr, maybe I’ve seen people post bad print results from HBots over and over and over for YEARS. There is never any case where HBot is as good as CoreXY. It’s physics. The drivetrain forces in HBots are unbalanced. In CoreXY they are balanced. It’s dead simple.
You CAN make HBots work – Stratasys has some that make great prints – but you need an absolutely, ridiculously rigid gantry, and that’s not what we’re seeing here with acrylic carriages.
Acrylic carriage only for test need cut it in metal same other part of printer.
I totally agree with @Ryan_Carlyle , hbot is a bit of a pain. I do not see that replacing the acrylic with aluminium will be fixing it. Sorry to be a naysayer here.
It will work but it will not work as well as you would like.
I built very accurate Hbot and it prints like arts, though it uses very rigid design with linear rail.
My bridge are strong too ,wheels not in nylon need improve softly my belt clip for permit belt tensioning
