AtCore is the API that does all the communication with the 3dPrinter. It is designed so that each printer firmware has its own plugin. This allows us to workout the lower level differences between various firmwares allowing us to providing the same features across all firmwares.
The Test Client is provided with AtCore. The Test Client implements all the features of AtCore for the purpose of providing way for us to test AtCore.
To use Test Client is simple, you can install it, and run. We have an automated way to find the port that the 3DPrinter is using it. So connect your 3DPrinter to your PC and wait for the port to show it here:
Now you need to set the baud rate of your printer, make sure to set this otherwise the return of your printer will be misunderstood by AtCore and you will not be able to connect it. On my case it's 115200:
After that you can click on connect and check on the log or the status bar to see if the firmware is loaded correctly and if the printer is connected. If AtCore fails to auto detect your firmware you can select on from the list. Most should work with repetier.
For temperature control, you can change to the second tab, where you can set Bed and HotEnd temperatures, beyond the fan speed.
When your printer is connected, AtCore will check every 5 seconds the bed and extruder temperatures. This plot shows the results of those checks.
For the move of the axis every piece of this pie have a default value to move the axis, if you pause the mouse on it, the tooltip will show you how much mm you can move. If you want to home one or all axis, you have buttons on your dispose to do it.
To print a GCode you need to click on Print File so you can load the GCode. When you click on 'Ok', the print job will start and a progress bar will be show below the log.
You have a few more features on the Print tab:
Last but not least, on the Command tab you have tools to push a GCode command by hand and Show Message where you can push any message that you want to show on the LCD of your printer.
