Subject: Which small computer (Raspberry or others) to run KmotionCNC

Hi Everybody,

which "small" device could be used for safely running Kmotion ?

My preferred solution would have been Raspberry/Linux but it looks like the port of KmotionCNC under Raspbian Linux is not yet completed (correct me if I'm wrong).

I then recalled somebody in this group mentioning Windows 10 on Raspberry as a solution, so I installed Windows 10 IoT on a Raspberry (with some difficulty) but from there on, I couldn't figure out how to install KMotion and KMotionCNC on it.

To make it short, could you suggest any "small/cheap" computer which WILL ALLOW to run Kmotion/KmotionCNC?
Possibly, devices that you have actually used with success.

I want to get rid of the big old "tower" size PC I'm using now.


Thank you
EC

How about a mini-itx sized motherboard/PC?

I've got one setup with Win8.1 installed ready to go in my mill, once I get a control panel built.

I was going to mount the itx board in the main control cabinet, but having thought about it, it's makes more sense to mount it in the control panel, as that way I only need to run a USB cable between the panel and cabinet for the KFlop, rather than a monitor cable, along with a USB and hub for a touchpad, keyboard and touchscreen.

Hello,
 I dont know about the Raspberry solution, but i used a Tangent PC i got of ebay for about $60. Came with a licensed copy of Win7 installed with COA. The PC is currently running KMotionCNC on Lagun a knee mill at work. Have not had any problems.

I am using a Jetway NUC format computer and loving the small size.  There are some Dell NUS's with Windows for under $200 ready to go.

Hello,
 
My favourite in this is the Shuttle X50 series.
I just unpacked my 4. unit.
 
I favor these for following reasons:
 
1. (the biggest reason)  All-In-One unit with touch screen
2. fanless IP54 design, mainly meant to run 24/7 in kiosks and such
3. has VESA mounting so easy to fix to an arm.
    I have all units arm mounted with simple alu enclosure w/ removable front fixed between the vesa mount and unit
4. Delivered barebones as standard so don't have to pay for useless HDD.
    I feel that with arm mounting a solid state drive is must because of the vibration.
   Mechanical HDD could survive but I don't have enough scientific curiosity to find out.
5. The touch screen is resistive.
    From my short experience with capacitive screens on elcheapo android tablet
    I concluded that capacitive touch screen is too risky to connect to a servo motor that moves real world objects.
    The mouse event recognition ( click, doubleclick ,up ,down) was not  consistent.
    Also since capacitive sensors read non magnetic objects it's reasonble to suspect that
    capacitive screen could also (coolant drops and such)
 
Rgds,
Tapio

Thank you all for the suggestions!
I was looking for something cheap but the expensive ones look tempting! ;-)

Hi Eric,

Just curious to know which computer you ended up with?

Hi Tapio,

I haven't bought anything yet!  Still running with the old dying XP tower PC....

And honestly, the suggested solutions looked very nice but not exactly what I was looking for. I was looking for something having the size and the price of a Raspberry  (given that a Raspberry port of KmotionCNC isn't available yet, otherwise I'd be very happy to just use a Raspberry).

The whole idea (at least in my mind) was to cancel the computer cost from the total cost of the machine.
If I have to add another 450 USD (that was the price of one of the suggested solutions when I looked up for them on the web), well, then I'd just buy another computer and the question is over...
