I have a square 1.5kw air cooled spindle I received from a buddy who works at a large cnc builder in mn shopsabre. I would like to put it on my xxl but would like to know the gantry weight limits first. Will the xxl handle this spindle? Also will I be able to add dust collection still or will I be pushing weight already? Lastly is a 1.5kw spindle really that much more power than the d 611?
I appreciate your answers I know it’s probably been covered but I couldn’t find the answers I was looking for.
Your 1.5kw spindle is engineered, designed, and made in China. I would think the 1500 watt rating is closer to 1000 watts (knowing that just about every rating I have measured out of China is OVER rated…usually by a factor of 2)
Thanks for the reply’s, One more question the z axis is there a upgrade for this like the old Shapeoko or is this axis stout enough? I see springs what purpose do these have and does the belt run it or does it run a lead screw. My xcarve was a direct to screw mount with a lovejoy connector seemed stronger.
For the new SO3, the belt drive AIUI, has the following design goals / advantages:
friendlier to newbies — a crash will skip teeth rather than tear the machine apart, configuration is simpler since the # of steps is the same / consistent across all axes
less expensive w/ an increase in commonality of parts which increases economies of scale
The springs are there to support the Z-axis when power is lost and should be adjusted so as to prevent an endmill from dropping to the wasteboard / stock and breaking
@RichCournoyer — you’re over-estimating the economic power of such small numbers of people. The entire boutique woodworking tool industry comprises less money than a single celebrity brings in annually:
(I bought a Bridge City Tool earlier this year, and it’s one of my favourite things ever)
It would certainly be an interesting job to see a spindle design optimized for the needs of our machines — given the proliferation of Makita RT0701 clones, you’d think it would be easy — the problem is the need for the larger collet — that would require a new mold for casting (I don’t think the larger collet and bearing would restrict the airflow so much that cooling would be an issue) — the other consideration then is would the current motor work adequately well / have sufficient torque for a 1/2" endmill controlled by a CNC, and what sort of liability would there be in folks using too-large endmills.
Seems easier to just run 220 or get a step-up transformer (and I just thought to check the price on that, so may have to go that route) — I will note that I am mystified by folks in 220 countries not springing for the Kress.
