Ran a couple (shielded) wires from the USB to the VFD and loaded a driver and it just worked. I did a ton of research when I put mine together and would be glad to share. If you decide to go that route and have any questions let me know. Id love to run 38 and, on occasion, 12 tools but without 220v in my shop theres just no way. So as with anything else, its always a trade off. Problem is, its a fools errand to run a 2.2kw spindle on 110v. Whereas the 2.2kw spindles will mostly come with ER20 allowing up to 13mm (or12) tools. The 110v spindles are limited to ER11 collets so nothing more than 7mm (or 14) tool shanks. In order to put a real 2HP to any work youd need some big iron rigitity and maybe larger tooling anyway. However it hasnt ever been a limiting factor for me in anything Ive cut. So long story short, the set I purchased is limited to 1HP. They assured the spindle was rated for 13A but it was moot since the VFD only allows 7.5A. The VFD limits the amps to (IIRC) 7.5A and the spindle itself was stamped with 110v-5A. One thing to keep in mind, although they say they are rated at 2HP, they are not. Ive read postings by guys that have been running them 8 hours a day in production for 2-3 years without trouble. Ive never had the need for support although I did have a after purchase question and they got right back to me. There are cheaper ones out there but be careful, a lot of times they have no documentation and zero quality control. My only advice would be to go for the water cooled over the air cooled as they cool better, seem to last longer, and most important to me, they are QUIET I cant hear mine over the fans on my controller and VFD. Im running UCCNC but Ive seen others running the same RS485 stick with MACH3 and they have no problems. Have read a bunch here, but most from a few yrs ago, so wondering what the current feelings are as to how it all worked out. What do most of you guysgals use Dont have unlimited funds but would like to do it right, as this should finally setup my CNC for awhile.
