i have a 1Kmm 2017 model,
and been thinking about how to upgrade the Spindle from 52mm to 105mm,110mm, or 125mm.
with a 3-Phase 400Hz 24k rpm, 3.2KW Watercooled spindle or more…
and a VFD from Invertek…
the reason is: bigger the diameter, Faster cut needs more torque…
bigger&fatter drills need more torque.
smaller drills need a faster spindle >60k rpm.
simple as that.
the original Spingle Carriage, is too small.
but 2x china sellers have spindle clapms brakets for 100m 105, 110, 125mm spindles,
but… do not fit the Original X-Carve Z-carriage, & needs heavy modification.
80028 - Extruded Carriage
25280-02_rev_1 Delrin Nut
is plastinc, needs to be modified to be aluminium nimimum, with ball screws.
14050 - MakerSlide End Plate
maybe is too thin, but its made from Steel, 12Gauge, maybe strong enough, problema definitaly are the aluminium rails, too weak.
Pinion Gear Ratio is not strong enough to move the very heavy 125mm spindle.
but china has belt pinion upgrades: 120 wheel tp 24 thooths.
1:5 Ratio that could work,
also Oriental Motor sells Step Motors with Reduction Gear Ratio 1:2
so it would be 1:10 ratio… “10x times stronger but slower Z-Axis.”
also the Lead Screw can be changed to one that has more turns per rpm,
increasing torque, but also Z-Time.
so 125mm spindle is worth it?
do i sell X-Carve and buy a Tormach ? “Ready” or a Probotix?
questions keep spinning on my mind.
main problem is that X-Carver needs a lot modifications… Before i can make my own modification…
would be step levels, modification levels. to achieve the desired strengh.
the ideal would be to make my own parts with the cnc but is not strong enought to cut steel, or aluminium, yet. to build it stronger.
so definitely ALL XYZ Upgrades are needed first…
also im using MACH4 with Parallel Port Plugin in W7x32 machine…
not a fan of Mach, because copy protection is linked to Board, HDD.
and they do not want to use a friendly USB dongle, like Steinberg eLicenser or ilok.
CNC computer must be Final, and dedicated.
No one told me that…
i lost al the activation licenses i had, testing different setups.
so Not a fan of Mach4.
Then a CAD CAM software + a very accurate digital ruler,
somethin like this:
to make the parts i need, for the next modification.
when that next modification is ready, build parts for the next level modification.
building muscle every step of the way.
will try NX Cad/Cam 30-day trial first…
but probably will end up using what everybody does:
maybe Cinema4D next…
