RPM Range of VFDs

Hey David,

@Arzt

But now (a year later, and in your opinion) which spindle makers can provide a North American “hobbyist” with a good combination of quality, capability and after-purchase support?

this was asked here the other day, a truly U.S. American spindle manufacturer is cncdepot.com

@Aiph5u

and there is also Glockcnc.

However Germany and Italy are countries with strong machinery industry, so you find → a lot of spindle manufacturers there…

Possibly there are much more spindle manufacturers in the US but it is difficult to find them since they do not address hobbyists. Mechatron is a manufacturer that addresses consumers and hobbyists directly, that’s what makes it easy to get a spindle from them.

Note that there are also big differences between cheap chinese spindles and expensive chinese spindles. See here the impressing video of noise and vibration comparison test between a cheap no-brand chinese spindle and an expensive brand chinese spindle.

Tom @TMToronto in this forum uses a spindle from this chinese brand (search for “@TMToronto ATC build”)

@Arzt

I hope that PWCNC (based in N. America) would bridge any other gaps in the quality of instructions (if they are sourcing their spindles from the Orient).

Here is the DELIXI CDI-EM60 Series VFD manual. PwnCNC VFD is DELIXI CDI-EM61. For the spindle, I would ask Daniel @PwnCNC what is the spindle manufacturer and origin.
