CNC Router build using aluminium profile.

I am building my own design 3axis cnc router.
As can be seen it is progressing well,but slowly due to cash flow.

The stepper motors and controller’s is 3axis Longs (Chinese) Nema23 kit.
3 pcs Nema 23 stepper motor with 425 oz.in3amp, dual shaft
3 pcs stepper motor driver DM542A, peak 4.2A, 128 microsteps, replacing M542
1 pcPower supply 350Watts (36VDC/9.7A)
1 pc Breakout board & 1 pc Parallel cable.
Mach3 controlled (all wired and working).

The machine frame is Series 8 Aluminium Profiles (from Metillin).
Main frame; Yaxis 120x80mm, Xaxis 160x80mm, cross bearers 80x80mm.
Travel aprox =
X-axis 1000mm
Y-axis 600mm
Z-axis 150mm
20mm supported rails (from Zapp automation) on all axis
1605 c7 ballscrews on all axis.

I have so many questions to pose to you all, so I will start with two small ones.
What do you think of the machine so far?
I plan to have duel steppers on the Xaxis, given the amperage per stepper motor, could the X-axis driver cope with driving two steppers wired in parallel?
