Sorry version IE 525.
Yes I understand you V. The reason for mounting on top of Z is because this machine will have a lot of weight at bottom, up to 8 hot-ends which is unbalanced and tends to incline when accelerating on X-Y.
I know physics and some mass on top would act as an counterweight, more or less effective depending of the Z-Pos. But also afraid of inducing to much radial (shaking) forces on Z-bearings.
If you maintain your opinion i’ll go your way 🙂
