Default Where to purchase CNC electronics thread

Guys I’m wondering if it would be an idea to ask the moderators for a Sticky thread regarding purchasing CNC electronics.
I’ve been searching high and low and am seeing some varying prices on stepper motors and drivers , and I’m curious as to where others have purchased their electronics and why they chose them .
This would be for everything necessary to build the electronics part , including the spindle and vfd , shielded cable , limit switches etc

I donít always insulate , but when I do .
Ok ,I never insulate

If someone wants to collate information I could see about putting one together from that. You'd need discussion thread(s) to find out the best equipment/price.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I shopped around for the best deal on the items I chose, Rick. My 3kW water cooled spindle is Chinese and I shopped eBay for the best deal on a spindle that met my specs. The VFD was a no-brainer; I bought from Drives Warehouse in Dallas.

My thinking was/is that I would rather have a top notch VFD with a Chinese spindle than to get the Chinese VFD and spindle together. I've read and heard in several places that the Hitachi VFD has far less electrical noise and better cooling than the knock-offs. That doesn't mean the Chinese VFD is junk and shouldn't be used, it just wasn't my preference. Several times I needed to ask questions about settings on the VFD and calling someone in Dallas was quick and easy. Those guys know their stuff!

Most of the other components I chose came from American sources where I can talk to someone and get support but I still shopped around for the best deal.

Hope this helps...

Actually your the reason I wanted to stay with Hitachi for the VDF , as I have seen a lot of bad reviews on other brands .
I wasn’t aware how expensive the NEMA34 steppers were , well at least the ones that I find .
I didn’t know there was several versions of them though, as the same size Nema can have different Torque specs .
Every time I find a kit with NEMA34 steppers snd drivers,it’s always for 3. I believe we require 4 .

Four of these ones I posted would certainly add up, and I think that’s in US currency . And I haven’t even gotten to the stepper drivers ,or the other associated electronics.
Almost should have ordered the plug and play , but that’s no fun

Does anyone with a cncrouterparts Pro know the shaft size for there Nema 34 steppers .
When I look it up I’m reading 11.9mm .
Kind if an oddball size, as that comes to .469” ?

I can remember several threads where members said that customer support from China was non-existent. That and repair parts are always an issue and general consensus is that when China is the source the problem is multiplied. At least when you get Chinese parts from a North American source with a good CS record it's because they chose to do business with a Chinese company with a good CS reputation.

Before it's all said and done you'll wish you'd have just got the plug and play!! Still plenty of stuff to tinker with. It's not just handed to you.

New contests to think about. Pick a date - when will Rick get his actually running, when will he actually make something, and when will he sell his first item? Oh........ and when will he insulate? (just had to)

I took the tests and retirement is the best job I'm suited for.

Now I know why old guys wear suspenders.

I was kind of wondering that myself after adding it all up , but I was really looking forward to building my own.
I noticed Avid CNC has things staggered and it looks pretty tight in there if you had to trouble shoot .
I was going to buy an oversized cabinet and mount it to the wall by the rear of the machine at standing height .
This would make it great to work on if I had to .
I also want to start with UCCNC right off the get go, and Gerry did mention that I could change the motion control board out in the Avid cnc cabinet , but I’d rather not.

Maybe I’ll be close to the same price when I’m done , but with better quality equipment.
I almost ordered their NEMA34 steppers this morning, but I believe they have a proprietary jack on theirs ?
I’d probably have to buy their cables to . Then you may as well buy the rest lol

I have seen better deals for kits that had all four Servos and stepper drives together. But I’m just not understanding the shaft size and design now.
Hoping it’s a standard thing

I donít always insulate , but when I do .
Ok ,I never insulate
