In the past I have written a couple of articles about my Printrbot Play with Control Center. And not a lot has changed on this.
Since the Last CURA has advanced to the point that it’s newest version is 64 bit only. this rules out it’s use on a a cheaper tablet, most tablets. So I have been looking at future options. The fact is true Tablets are on the wane. in their place has risen the 2 in 1. These are Laptops that have a keyboard that folds all the way back so that they can be used as a tablet. On the good side many of them have processors better than an Atom based CPU to choose from. On the bad is most of them use a laptop power supply at 19.5V.
The Atom based Tablets mostly used 5V power in from a cell phone charger. So getting 5V from 12V is relatively easy. You can get 19.5 volts from 12V but it is more expensive and larger in size. Some printers are 24V so this would not be a problem on those.
Since these 2 in 1’s come with a keyboard there is not the problem of trying to find a TRUE Bluetooth keyboard and mouse for ease of use. And they are lightweight so there is no reason they cannot be mounted to the side of a printer. They are found in sizes from 11″ to 17″.
The primary one I have been looking at is the Dell 11″ 3168 2 in 1. It has a Celeron N3060 Dual Core processor, 4 GB memory and 32GB SSD, 64 bit Windows 10. It has a lot of connection options which are nice compared to Tablets. It has 2x USB 2.0, 1x USB 3.0, a MicroSD card slot. So much better connection options than the tablet. You have enough USB ports that you can use a cheaper mouse with dongle. and you can use a USB3.0 stick to backup your files or transfer files to the 2 in 1.
New this costs about $249, outlet $203. Considering the 64 bit operating the 32GB SSD might be a bit on the small size. But it has an upgradeable drive bay as they can also be found with a 500GB HDD. A SSD is preferred for use as a control center because of vibration from the 3D printer. I think a 64GB SSD drive would be large enough. But the Micro SD card could be used for that extra storage to keep the price down.
There are two ways to power this from the printer. 1. Tie it into the 110V to the printer. when the printer gets plugged in so does the 2 in 1.
- A Boost converter to raise the voltage from 12V to 19.5V.
I do not consider running off battery a viable option. Even with screen blanking and such active you could easily end up with a print that is longer than your battery life. You cannot let the system power down as it is streaming the code to the printer.
Overall I am contemplating the move to a newer control center computer. Newer software is all going to 64bit. The added memory will really help with programs like Sketchup. The CPU is not a whole lot more powerful than the Atom in the tablet.
I recently let my Nephew borrow the Play with tablet. He did not have any experience with a 3D printer. He found it very nice to have the right programs and drivers already waiting rather than have to install all of that on his computer, then try to figure it all out. He was printing on it in minutes and had a very good experience. He now has an upgraded play his dad gave him. Then he found out what it takes to get everything working right versus it is setup and ready to go. He also agrees that having a computer integrated into a 3D printer would help bring them into the mainstream. He liked that he could use the printers tablet to get into Thingiverse then download and be printing very quickly. Currently he sneaker nets a SD card to the printer which he runs in his wash room due to noise.
Good printing everyone!
