OpenPNP and other stuff server requirement
« on: September 02, 2018, 06:31:02 pm »
Hi gurus here,

I'm looking for a computer that can do the following things as a home server:

1. Control an OpenPNP-based PnP machine (OpenPlacer) with 2 cameras,
2. Control a GRBL-based CNC (Carbide 3D Nomad 883 Pro),
3. Serve files from a relatively slow HDD array (software RAID 1, up to 200MB/s) over Windows file sharing,
4. SMB also shares a Canon printer,
5. Run a Brother scanner,
6. Stream desktop to another computer over RDP remote connection.

What kind of hardware should I need?

Here are two candidates that I have:

1. Intel NUC with Haswell i3, 8GB RAM, 256GB SSD
2. Intel NUC with Kabylake i5, 16GB RAM, 512GB SSD

I have both, but I want to sell one for some cash. Since I don't have OpenPlacer set up already, I can test out for real.
The second one has a 28W CPU that's more powerful than most high end Ultrabooks, so I have no doubt for it.
However, I prefer to use the first one since I can't really sell the first one for any reasonable amount of money, so I prefer to get rid of the second one.

OpenPNP knowledge is much appreciated from PnP gurus here.

What you want to achieve is relatively low-end stuff. They don't take a lot of computing resources at all (even all at the same time).

Your i3 NUC would do the job fine, but I guess it depends on how desperate you are for the money? I'd keep i5 NUC for myself and sell the older one but as you've already stated, you already have a preference so go with that.

Although, if at all possible, avoid Windows 10, it's complete garbage. I actually find it slower than Windows 7 in many ways.

Does OpenPlacer actually use the cameras for machine vision during operation? That can be quite GPU intensive.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Machine vision and RDP is all what I'm concerned about. Keep in mind the i3 is a 15W SKU without turbo boosting.

I'm not really desperate in cash. I just bought a maxed out X1 Carbon, and I just want to consolidate my computers and liquidate the excess.

Forgive me if I'm too outdated, but last time I used OpenCV (back in 2014), it didn't support GPU well.

It has improved by a lot. In mid 2017, I worked on a test setup that used GTX 580s (what they had lying around) as part of a machine vision system for automated testing.
