Will, easy way to think of PWM is on-off, just very rapidly with varying mark space ratio, in most cases on-off can usually suffice.  My router has a 3 phase spindle, but the old controller couldn't control it, so I just used a single line to toggle the spindle power and set the speed manually.

I was/am looking at the Arc Euro X1LP as a possible cnc conversion.  It could also be used as a ganged lathe for small stuff.  I already have a suitable UC100 USB controller and UCCNC software, so would have a hard time justifying to the BOSS that another controller would be a wise purchase   :poke:

However toys are toys   :D

Any hints/tips/suggestions please ??

I made one mod to the box.

As shipped, the unit runs from 12VDC. This isn't so bad as most CNC driver boxes and up with a few different supply voltages in them.
Because I wanted to be able to just plug this into a bench supply and run the drives and controller from 24V, I made a small change to the units power supply.
The switch mode regulator used will happily handle 40V input, but, for reasons unknown to science, the designers elected to put a 16V electrolytic cap on it's input.
I swapped this for a 35V 220uF and now everything runs fine at 24V.

Hi PK

Cool project  :thumbup: , are you making your own filament ? 



 I myself have been looking at purchasing one of those CNC controllers from Banggood  for a CNC Plasma project .

 http://www.banggood.com/50KHZ-CNC-4-Axis-Offline-Controller-Breakout-Board-Engraving-Machine-Control-System-Card-p-1021134.html   

Seams like a good way of getting away from Mach3 and the space saving of not  needing computer and screen .

Whats your thoughts on build quality ? using the micro SD card to load files ?   


Thanks Rob

Most interesting question is: What it is used to? To make extra high Q coils or to make extra lightweight and strong boron/unobtanium composites?

Or something even more exotic?

Sorry for hijacking your thread. Since there is a lot of interest in your control box, I thought I'd post some potentially useful information for anyone planning to buy one.
 
I've bought one of these http://www.aliexpress.com/item/DDCSV1-1-500KHz-CNC-3-Axis-Engraving-Machine-Controller-Motion-Control-System-G-Code-Stepper-Motor/32594969297.html?spm=2114.13010608.0.90.tXE321

It is waiting to be fitted on to a 6040CNC router when I get some spare time. It seems to have better specifications than most other similarly priced single  box controllers. The user manual is 95% understandable and actually has a decent amount of information in it. If you are buying one of these single box controllers, make sure that it isn't one that has a limit on the number of lines of code that it can process. They don't make it clear on the advertisements. That information is usually buried deep within a poorly written and even more poorly translated user manual.


Here is a link to the user manuals for the commonly available ones http://www.chinaplccenter.com/support/Manual-Download.html

EDIT:
If you can't find the manual for the one I linked let me know. I can email it or upload it here.
