My 1st Hybrid Steel/Ally (1150 x 850 work area) (comments/advice please)

@lebies
There are other things but for a start these jump out at me.

1. A spindle with at least an ER20 collet is a MUST I would say, also a 2.2kW spindle would suit the machine better.
2. The Z bearing blocks are too close together in the vertical direction, these will be weak regarding twisting as they are.
3. With an X of 1200 you might find 16mm ball screws will whip at higher speed but I'll let jazzcnc comment on that, he might suggest changing the pitch to slow them down.
4. You might need to think about 20mm rail instead of 15mm
5. Rather than a long Z travel, think about an adjustable bed. The Z will be very weak at full extension as shown.

I look forward to seeing your control panel design.
