What is this file, and what does it do, exactly?
]]>your power draw shows about 2.5amps so that's close to limit when figuring safety margins of power supplys and line voltage fed to primary which can very also.
The 2.5A total power draw is a worst case scenario. The largest single component draw is the stepper motor. The NEMA-17 stepper motor would draw 1.5A only when it's trying to hold a position under torque, there's nothing in this design that puts undue load on the motor, so actual average draw for it should be less than 1A, The lasers power draw is inconsequential, and is not continuous. Last but not least the Pi and the camera together are less than 800mA.
So it's safe to say that total power consumption is probably less than 2A. The Little 3A wall wart that came with it is more than adequate.
the scans I done when started said 120mins left I think thats 2 hours and thats what they took. and if anything disrupts scan either connection or power all you got is partial scan file saved and you cant continue or restart it. have to start over. happened 3 times to me so far. WHY would I make this crap up?
The reason your scans are taking 2 hours is because you're scanning at hi resolution and 3200 steps. You don't need to scan @ 3200 steps. 1600 is more than enough to get a good scan. Additionally, I can tell you from personal experience that scanning a detailed model at 3200 steps will most likely fail at the end because the RPi doesn't have enough RAM to process the the scan. I had to get a RPi 2 with 1GB RAM to be able to scan @ 3200 steps.
Before you start scanning stuff at 3200 or even 1600 steps, you should debug your system using faster scann like 800 steps which should take about 25 minutes or so. Once you get those going OK, then you can move on to higher quality scans.
If you want to see detail on your small models then you will definitely need to refocus the camera. Se the instructions I posted elsewhere in the forum.
the preview etc is why I want to open through FF instead of dumb IE which will no longer update on XP OS its stuck on IE8
To see the preview during scan, you will need to make sure your browser is WebGL enabled. The latest versions of Firefox work OK, Chrome should be OK as well but you need to check, IExplorer 11 supports it, but I don't think earlier versions do.
Safari should work, but it's disabled by default. Additionally WebGL requires a compatible display adapter.
the file that came with it is one my desktop and when opened if Atlas is connected to router a box opens saying 'connect to Atlas' when clicked it opens Atlas in IE.
I really have no idea which file you speak of. My scanner didn't come with any Windows based software, there was only the SD card which contains the Raspberry Pi and the FreeLSS software.
No additional software is required on the PC. Just start your favorite browser (Firefox, IE, Chrome, Safari, etc) and connect to the scanner's IP address.
Maybe I'm behind the times, and there's some newfangled way of using the Atlas I'm not aware of. Can some enlighten me as to what additional, PC based software the Atlas 3D includes now?
]]>Explain to me HOW can Atlas 3D scanner force you to use use IE. How in the heck does a device connected via a network (Ethernet or WiFi) manage to start your Internet Explorer?
When you connect the scanner to your computer, either via Ethernet or WiFi, IT DOES ABSOLUTELY NOTHING until YOU personally start the web browser to connect to it's start page.
How do you know the power consumption is at it's limits?
The Raspberry Pi with a WiFi dongle draws about 500mA. The RaspiCam, another 300mA, and the 2 lasers 25mA each. That's less than 1A. A NEMA 17 stepper motor like the one used to drive the turntable is about 1-1.5A. all this adds up to less than the power supply rating of 3A
A complete scan shouldn't take 2 hours to complete, even if you scan at 5Mpixels, and 1600 steps per revolution, it will only take about 50-60 minutes. The type of connection you have (or how fast or slow it is) is not relevant to the scan time. The scan process happens inside the RPI, and is not dependent on your PC or your connection the PC.
If you can't preview the scan, it's because your browser is not setup to support WebGL. There are many posts regarding this, search for them.
]]>The info provided by Vinoh was the trick:
]]>The comments above are based on the original model.
]]>My only issue with the WiFi dongle was the configuration. Once I was able to modify the config file to input the SSID and password, it worked just fine.
With regard to speed, yes, it's pretty slow, but then again, for using it to control the Pi it's adequate. The only time it becomes an issue, is when you try to download or view the scans. Depending on your connection quality and the size of the file, you could be waiting for a long time.
For that reason, I too use it wired to my ethernet.
