Hey guys new member. advice needed

[tankproof2]

Ok, so i have done some research and come to some conclusions. but i have a few questions.

i have found multiple options for a few things and would like to ask which is best


spindle- they are all around the same price but with different vfds but which is the best?

steppers i am thinking nema 23 and these are the options i have found which is the best?

drivers-

i am thinking of going for a way over kill driver to give me head room for new/ more powerful motors

options are the cw8060 https://www.aliexpress.com/item/6127...archweb201603_

or cheap out and get some https://www.aliexpress.com/item/3291...c00DrQIm1&mp=1

my question is what is the best cheap stepper right now?

as far as voltage goes i am thinking 48v but is this too high?

Ok well the first spindle is the better choice because of the VFD, It's made by Huanyang and is well tested on 10,000's of machines, the other two are copies and lower quality, that said even the huanyang isn't the best quality in the world but I personally have fitted 100's with less than a handful of issues so wouldn't hesitate to fit one or recommend buying one.
The Black one I've only fit on a couple machines and wasn't impressed with them, the white one I've no experience other than I know someone who had one and it blow up after 7 months.
The spindles are all the same. One other thing to mention is the water pump.! These pumps included in the kits are 230V Mains powered and DONT have an earth which isn't cleaver in a submersible pump IMO. I won't fit them.!

Motors:
The first motors with intergrated drives are not steppers they are DC servo motors. Never used so can't comment but 180W isn't a lot with only 48Vdc and won't suit a large machine.

The second motor is a run of the mill stepper, nothing special.

Drives:
The CW8060 are not very good drives at all and certainly NOT going way over kill.? 80Vdc drives are what you will need for a decent sized machine to get the higher feeds you'll want.

The cheaper Dm542 are ok for a small machine but are limited on the Max voltage at 50vdc, for a large router like what your planning then you'll want to be running your motors with around 60-65Vdc to get the best speed and torque from them.

Now personally I wouldn't fit any of these because they are basiclly OLD technology, Newer Closed loop motors with Digital drives are much better and won't cost much more money.
Also look for drives that provide AC input and it will save you the trouble of building a DC power supply and a little money.

However, why are you even looking at buying this lot when as far I can see you haven't even decided or designed the machine yet.?
You are a long long way off needing any of this and while it's tempting to buy so you can test on bench all your doing is wasting warrenty and they will learn you very little.
Also, without knowing the Mass etc of the gantry you could easily buy the wrong size motors/drives.

Again I'll advise you to NOT BUY ANYTHING and say go do more research on the motors/drives and why voltage is very important. But only so you have a better understanding of why getting this part right is so important and not so you are better armed to buy now. Only buy when you need or close to needing them.

Hi Jazz - hope all is good. Sorry to thread hijack, just read your comment about the 230V pump - while running mine today I remembered I'm still using one of those potential death traps with no earth submerged in coolant! From what I can tell (no details with it) its probably 3000L/Hour flow rate .
Do you recommend a better 230V pump or 12/24V versions? Thanks

To be honest I just use 24Vdc pumps that they use for solar heating, they are cheap and safe. Plenty of them on Ebay.

Ok thank you that was very helpful, i will do more research, as far as the motors can you recommend me any closed loop steppers that are cost effective? i am still planing the build but looking in to maybe buying a used/ ebay custom steel frame so just looking for how much steppers ect will cost me so i can price it all out

thanks again Tank

i have found these steppers here (https://www.omc-stepperonline.com/ye...nd-driver.html) they are closed and not to expensive, are they any good?

They are ok but again they are only 50V drives and this will limit the speed/torque.

But today could be your lucky day.!! . . . I've just received a shipment of 50 sets of Lichuan Closed-loop steppers. 4.5nm and 5.5Nm that use AC volatge. A large number of these are allocated to machine builds but I have about 10 sets spare that I would be willing to sell.

I also have Ethernet controllers from CNC DRIVE that I would sell. I have AXBB-E and UC300ETH with the UCBB Breakout board. Also can provide UCCNC license files at extra cost but lower than you'll pay elsewhere.

In a few week's time, I'll also have 2.2Kw spindle kits. Similar to what you were looking at with Huanyang VFD etc.

PM me if you are interested.

ohh awesome will pm now

Sorry for delay I was at work when posted that and didn't see your post or PM until got home, but PM sent now.
