hi there, can you call a switch mode (AC-DC) power supply CNC power supply, or it will supply power to CNC machines?

 

Anything which supplies power to a CNC machine could be called a CNC power supply. If it doesn't it couldn't be.

You sound very knowledgeable in this subject. Would you also call a power supply that supplies power to a PC a PC power supply?

Typically a CNC machine is never supplied via a SMPS as a principle supply , but they are sometimes used inside the system for minor, low current tasks.

Mine doesn't feature a single mains transformer - 100% SMPS.

Yes, I have always found them to be completely inoffensive.

What make? Industrial or DIY?
I would never use them for servo/stepper supplies. Even the servo/stepper drive manuf do not recommend it.
Also regulation is not needed.

Yes, and excellent value and function.

I think you did mention you used it for isolation routing of PCBs? How are your results? I have never been satisfied but might be willing to try again. If you get good results what are your secrets?

I have been using it in a hybrid process. I drill first then use toner transfer method, printing to wax paper, so I can easily line up the holes.

 

0.3mm tracks & separation. At a push it will do 0.2mm. I am currently working on software that will let me do D/S with plated holes.

From a couple of sites I visit, some of the Chinese machines are notoriously bad with safety/code issues.

None of the electronic box covers were earthed but that's easy to fix.

The problem is that everyone does not have the background to detect any of the code violations!

The problem is that I don't want to pay ten times the price for someone else to add some earth connections. The bit I can't do is the mechanics and they are pretty good for the price.

 

I recall an incident on one DIY CNC forum where I visit, where a person was asking advice on a machine he wanted to use in a school.
The pictures he posted of the Chinese components he wanted to use included a power supply unit that had 3 AC power sockets for some eternal actuators, the sockets were the male variety!
I think they withdrew it after I pointed this out, remember, this was for a school!

I never did anything to mine and I never had an issue. And I am not planning on touching the box and a water pipe any time soon.

 

As I wanted to add a probe connection for auto-levelling I had to go in the box and adding a few wires was no too taxing. That is well within my skill set but making the mechanics is not.
