well it took some fiddling around, not because the tablet gave me a headache, but simply because it had already been a while since i last did all the prepping steps...

In the end it performed wonderfully. I had an issue with it discharging while plugged in, which would be problematic for long jobs. Anyway it turned out I got a terrible quality usb cable. Once I switched it with my phone charger the issue was resolved completely.

For some reason it paused the cutting process when the screen turned off (I had enabled this bc of the charging issue). I thought I set it up so it wouldnot enter sleep modus but I probably missed something. Anyhow, since the charging issue was resolved I just set it up so that the screen never turns off while charging. problem solved.

So basically if you set your power options accordingly and have good cables this tablet really delivers.

I did a test cut and was planning to make a video of the whole process, but somewhere mid-job something went wrong and I had to cancel it. Nothing to do with the tablet though as i also had the same issue with the laptop i used before.
I better figure it out before doing more serious cutting.

Too bad I cant show a vid, but all in all I consider it a success!

Greetings xfredericox, et al,

After trying unsuccessfully to find an industrial computer for less than $750, I, too, decided to try the HP Stream 7, port replicator, and Arduino running Grbl.

I have only gotten to the stage of being able to charge and identify things being plugged into the Plugable Pro8. I have not been able to get the tablet to recognize the Arduino.

What was your trick? I have tried changing baud rate, flow control, etc. I still cannot get it to recognize the arduino, let alone communicate via Universal G-Code Sender or Grbl Controller 3.6.

Thanks for any input.

-Paul

First question, are you running the Windows 8.1 version or Android version of the tablet? If running Windows 8.1 make sure you install the Arduino software. Second, make sure you can see the Arduino with just the OTG cable.

Let us know what you have or have not done to troubleshoot.

Yes you must install the arduino software/drivers.

Chances are you might need to manually install the driver through the "device manager" window.

everything is explained here:
http://www.arduino.cc/en/Guide/Windows#toc2

For Windows 8.1 you only need to do steps 1 to 4.

if you are running UGS, you need to install JAVA too

Please note that Steps #6--9 will wipe Grbl, requiring that it be re-flashed.

To everyone who replied, you're awesome.

I was able to validate the hardware functionality with a PC. I do not recall installing the Arduino IDE on this computer, so I didn't consider that a requirement.

It works fine, now.

So the tally is:
Hardware: HP Stream 7, Plugable Pro-8 (charge and port replicator at the same time), Genovation ControlPad CP24-USB, Arduino Uno SMD edition
Updated software: Java, Arduino IDE, Universal G-Code Sender
Other make-it-move hardware: 48V/350W power supply, Leadshine stepper driver and Nema 34 stepper and a 12V PS and Pololu DRV8825 running a Nema 11 frame stepper. (Stepperonline, Pololu, and Mouser)

Now my Kevlar winder works on a <$300 controller.

Thanks again for the input.

-Paul

For future compatibility and because I think it is a step forward again, I am currently installing Win10 on the Winbook TW700.
Since it is nearing its release date, I think the latest build will be more than stable enough for the use I intend it for.

I am still in the process of installing, but already it seems a better choice compared to the other tablet discussed here. I can simply insert a USB stick in the native USB port. I am not sure whether an external splitter/hub will be easily recognised while working in BIOS.
Anyway I am glad I don't have to worry about that.

With the small screen, has anyone run into the issue of the font too small? The issue appears to be predominantly shown in Universal G-code sender. I am still working on getting GRBL controller 3.6 to run.

Yea... the font is small, but I think you can control that in Windows. I got my Steam 7 connected to the SO2 yesterday. Only had time to do a few jogs but worked great.

No longer have a Shapeoko, but use a machine of my own design...

it is small,yes.
GRBL controller 3.6 is better, but still small.

To change windows zoom setting:

you set it to whatever you feel most comfortable with. More zoom obviously means smaller resolution.
Personally I keep this at 100% and use a stylus I bought for 3 dollars off eBay.
