How to control the SO3? Oh, so many ways...

Post by MidCitySlim » Tue Apr 26, 2016 6:20 pm

Currently, I run my SO3 using UGS with a standard laptop. I want/need to get away from using said laptop for various reasons. I have read about a couple of inexpensive options, and can't pull the trigger on any particular one... I use a PC for Fusion 360 CAD / CAM, and use Dropbox to send .nc files over to the Laptop (I like this feature). I just need to determine how to control the SO3 using .nc files.

1) Raspberry Pi - I have a RPi sitting around collecting dust. I would need to buy a dedicated monitor to complete the setup. Estimate $50?

2) Win 10 Tablet. I have read that people are using something like the HP Stream 7" tablet to run their SO2 and SO3. I see various tablets on Amazon for about $50. I feel like this would be the easiest / cheapest option, and I could use Dropbox still. Only challenge is for long jobs, the charging port is also the comm port. Might require a USB hub / added cost.

3) Basic used laptop. Estimated cost - $100? Simple enough.

Thoughts?

You should be able to use a Raspberry Pi w/ no monitor --- just use VNC to control from your laptop.

Nice in theory. But my laptop and PC are both in my office - SO3 is in the garage. Not terribly effective in setting up the job (homing, zeroing, probing for Z).

I'm a fan of cheap old laptops running Linux.

You should be able to pick something up for less than $50. It doesn't need a fast CPU, lots of RAM or lots of disk space if all you are doing is running UGS or bCNC.

I'd like to use a Raspberry Pi, but pretty much my whole CAM workflow is Windows-only at the moment, and it would be really nice to be able to make small tweaks on the same computer.

I've noticed that a local office surplus store is selling old Dell workstations for $20-30, so I might check that out sometime.

You could always add a small, cheap screen for the RPi. That's what I intend to do, I want to work at home like I do at work - all CAD/CAM programming done in the office and then take a USB stick loaded with G-Code out to the workshop or garage. With a screen to display position and data, you should be able to set your XYZ datum on the machine without your PC/Laptop.

There's two threads I'm currently engaged in and find the contributors of both to be very helpful;

Thanks. I ended up going to an electronics graveyard and picked up a nice little 10" laptop for $50. This saved me the time and frustration of building out my RPi to control my SO3.

When purchasing a cheap laptop, make sure it has at least 2 g ram, to run carbide control.

I have a raspberry pi and a crappy walmart LCD TV with HDMI input running Universal G-Code Sender

I use one of these for homing and control - https://smile.amazon.com/Rii-Wireless-K ... s+keyboard

I use a 10 year old laptop (1 core 1.5G of RAM), running Lubuntu with either UGS or bCNC. It works fine, but the backplot for complicated jobs can be a bit slow to refresh.
