Be helpful, give price n link…

I got it off amazon.

$170, the link was just sent.

I love the inverter from smw3d but I don’t think it will handle 2.4k watts. The company makes larger versions.

6

Will you also have issues adapting to the different frequency of the mains?

7

I don’t know

Will that help?

Nice. That is what I use for my 800w spindle.

I was able to find a few packages on ebay with a 2.2k spindle and inventor. I wish I could support the 12lbs. What machine are you using?

13

@Colin_Kaminski either my open builds Ox, or I might use some supported rails I have to rebuild the x-axis using some 8020 extruded aluminum. SMW3D has also come up with a new model (R7, I believe) that looks pretty sturdy. My Ox was able to support the weight of my Bosch 1617 Router, but the gantry isn’t very rigid.

14

@George_Allen I am running the R7 and I would worry about torsion on the Z-axis.

15

I may be out of luck then. I’m curious, what kind of controller are you running and do you have to use a braking resistor?

16

I viewed a set-up of someone making a CNC out of a precision matthews, and it’s a pretty complex, but thorough design. He has a Youtube channel, I subscribe to.

@Justin_Adie I may well have gotten off, over my skis purchasing this, but I do want to stay as safe as possible, and hopefully not tear anything, or much, up. I have a question for you: if I have a 1.5 KW VFD, would that be sufficient to run that spindle at the lower power level, or would that not work, if you know? I’m no engineer, electrical or mechanical, so any warnings or advisements you are aware of will definitely be heeded.

@Colin_Kaminski Thanks for the input…I may need to rethink things. i may not be able to use the spindle. I have a VFD, but it is only rated at 1.5 KW. Would it not be possible to run the spindle at the lower power, or would that not work/break something?

I think the idea of VFD is it is constant power but variable speed but I might be wrong. I am running a TinyG with no breaking resistor. I do not control the motor speed with the TinyG although I do plan to add it. It is a pretty simple circuit to change the spindle output of the TinyG to what the input of the VFD needs but I am slow designing electronics.
