Even as a first-time, scratch build, it's reasonable to do the mechanical side in only a few hours. Even as a first-time, scratch build, it's reasonable to do the mechanical side in only a few hours.
Even if you're also doing BoxZero at the same time, the gantry can stay in place, with changes around the gantry. Even if you're also doing BoxZero at the same time, the gantry can stay in place, as you work around it.
The build order isn't as prescribed as a V0, because the bedrame can be easily added and removed, and because the motors can go in before or after the MotorCorners... this is an under-appreciated benefit of T0.
