For G-Code files the only limitation is the storage capacity of the device. G-Code files are streamed directly to the printer. The slicing has already been done, so there is no heavy lifting involved at that point. However, you will not be able to view the G-Code file unless it is less than 10 Mb. This is the same for the old T7 and the new T7X.
As far as I know, there are no current plans to add this functionality to MatterControl Sync. However, I'll be sure to let the developers know. As a workaround, you can always upload a .gcode file with the commands you want and then "print" it.
We're also working on another product right now which might interest you, which will be called MatterControl Connect. It is a WiFi dongle that you will be able to plug into your printer, and then be able to control it remotely from your computer as if you were plugged in through USB.
It means that your model is too complicated for the graphics processor on the MatterControl Touch (i.e. the model has too many polygons for the GPU to handle). You can still print your model, you just cannot view it before printing. If this is an issue, then you can either slice it on a PC and send the G-Code over or decimate the model to reduce the number of polygons.
Make and Model are irrelevant, at least for connecting. In the context of MatterControl, a successful serial connection requires only the correct serial port and baud rate to be selected; everything else in the MatterControl profile is specific to the printer's attributes for printing.
That said, connecting should be pretty easy, assuming that the printer and tablet are functioning normally. Do you have another host (like a computer, running MatterControl or another printer control software) that you can test the connection with, to isolate the printer or the Touch as the problem?
Yes. From MatterControl on your desktop computer you can upload gcode files to the cloud library the same as you would with an STL file. You can also send files directly by going to the Queue and choosing Send from the More... menu.You are correct. None of the slice settings need to be changed. The T10 only needs to be able to communicate with the printer.
As of now this functionality isn't possible. I'll make note of your request for the development team as they look for new ideas.
The only workaround I can see possibly working would be some kind of third-party Android app running in the background, but depending on the other app's processing requirements performance may be affected.
Thank you for the info. I must say I hope things can be resolved because the 3D view, the settings, the intuitive interface, etc, are all awesome. The same is true of the desktop version. Thank you again for the support.
