I will bookmark this for my next CNC.
Thanks

I was looking for one of these but i could not find one available for Australia. And few that i did find were over priced.
But it's all good now, i'll just use the 5v2.5a power adapter that i have.

The 5.3V was from a old mobile charger. I thought the current might be a bit low, at 500mA.
The 5V2.5A was from a external usb hub.
Thanks All for your replies.

Hey All,
I wanted to power my Chinese BOB with a power adapter instead of the USB port.
I have 2 adapters to chose from, 5.3v 500mA or 5v 2.5A.
Which is better to use to power my chinese CNC BOB....

Thanks for the information. i think i have a spare adapter from an old modem/router thats 5v 1a.

Hey all.
I have a cheap chinese 5 axis controller and wanted to know what amperage to use when powering it. I know it is 5v but have no other info on the amps required.
I will be powering it with...

I am using a 48V16A regulated switching PSU to power my whole CNC milling machine and wanted to ask for advice before i wire it up, so nothing is damaged.

Here are the various parts that i will be...

I was wondering if others have some type of power protection on there systems, against power fluctuations or any issue that might damage there electronics.
I was thinking of maybe adding in a fuse...

Hey guys i finally ordered the PS and i am just waiting for delivery. When it arrives i will be back to get some extra help :)

Thanks

So i have bookmarked that 48V16A PSU and will be ordering one at the end of this month/beginning of the next month. Hopefully the price doesn't go up.
I will let you know once i have it.

@dharmic In regards to the 48V16A PS that you linked, i just want to make absolutely sure that i can plug that into a 10A household GPO? without causing problem for that circuit.
I am asking because...

Hi Paul You are (kind of) where i was 3 years ago. Wanted to understand CNC Routers and/or Milling. For me i just watched a lot of videos of different people building the machines and then researched...

ok, so two 48V might not fit my needs as well as the link dharmic supplied earlier.
However i think with the single 48V 16A i would still need to separate the required power for each purpose. i.e...

The Link that dharmic suggested looks good. the price conversion is $150 including S&H.
I'll need to save a bit for that one but it currently looks like what i might need. Thanks dharmic for the...

Ok so the RS website does not have what i am looking for. Hmmm

I was looking at the chinese PS. I found this. not sure if it is what i need.

Specifications:
Material: Metal case

@dharmic Yea, I am on RS website at the moment trying to find a transformer with the necessary outputs.

@RCaffin


I have been looking for a while for the transformer you mentioned (i believe it was something like this, a 240VAC10A to 48VDC 16A)
But i can't seem to find it, either the volts drop...

so if i use a 48V 6A PS what is the best way to get the 5V needed for the logic.

I'm in Brisbane
How do you get a 16A on a GPO rated for 10A or is it a 20A GPO on a separate circuit that you have?
Here is a link to the spindle i have. SPINDLE

I looked at the VFD's, lol way...

Thanks for the info Roger.
So i should be able to use a 48V 6A PS, (if i understand) for the steppers and drivers?
and a separate 48V 10A for the spindle?
Would that be fine in a single GPO?
...

@RCaffin For the steppers you said that if there is a sag in the voltage at peak load that it won't matter. But wouldn't that damage the steppers?
it sounds like your suggesting much less voltage....

@GavWA Thanks for the reply. you are correct being rude or sarcastic on a forum that is meant to help people only makes them feel that they can not get help here,
and probably injure them selves...

Thanks for that. Still need more info on stepper motor power requirements and usage.

Thanks Snowy, Looks like that might be what i need. Time to start reading (again)lol

Thanks

I am trying to find what PSU i will require to get my CNC up and running.

Info:
Steppers: Nema 23- 75V 2.8A Impedance: 5.6mH Link:Nema 23
Step Drivers: 2M982 - 24-80V 7-16A Link: 2m982...

True Both Lakeview and Williamstown do mainly sell 6060 with the odd piece of 6061. and i think the short pieces (300mm) might be because of freight. I believe they can sell longer parts but mainly...

Hi all. My name is Linrox from Australia. Starting to build my custom designed large scale 4 axis CNC Mill.
I will probably be asking a few questions, but I also do a LOT of research and like to...
