Question about using More Powerful Heavier Makita

For Shapeoko 2 with Nema 17s, 600 watt quiet cut DC spindle.
I have used a for awhile. I know its limits.
Recently I have got a mount and attached a Makita RT0701. Still using the baby Nema 17s.
What can i expect with the tradeoff of the lower powered lighter DC spindle vs the bulkier heavier AC Makita?
For example
Will the heavier Makita move faster without skipping steps because it is more powerful or will the nema 17's choke?
Can I use larger cutting bit diameters (not shaft diameter) on the Makita, like 1/2 inch to clear large areas, or will the nemas ckoke?
Will the Z axis stepping be affected due to the additional weight?
The DC spindle can run for hours on fine detail work; how long can the AC Makita run without burning up?
Any other comments or tips for using the Makita would be appreciated.

((I have considered upgrading to Nema 23s but I think if I did that i would want to upgrade the board, and even if i did that, i would want a stronger frame as well... in other words, Just get a larger CNC machine like Shapeoko 3!)

Considering my Shapeoko 2 and Nema 17 constraints:
Looking for different types of jobs you do and what spindle (router) would be best.

Thanks

I had good luck when I mounted a Harbor Freight 1/4" trim router, and then a Makita RT0701 to my Shapeoko 1 --- the mechanical advantage of a screw makes it pretty easy for the machine to cope with the added weight.

You should get a lot more power and speed in cutting, and be able to adjust feed rates commensurately.

That gives me a little relief about using the nema 17s.
In the meantime I ordered a set of 1/4 and 1/8 inch collets from Robotshop.

The dc quiet cut spindle could run for hours.
In your experience how long would you let the Makita run at a time for a job?

Thanks

I've done 6--8 hour jobs, w/ a couple of breaks for food/tool changes.
