Add support for Anet A8 firmware

[vincent-ogury]

Before reporting, check if your problem is here: https://github.com/eyal0/OctoPrint-PrintTimeGenius/wiki/Common-problems

Please fill this out:

OctoPrint Version: 1.3.9

PrintTimeGenius Version (if you know): 1.1.0

What did you try: Analyze a gcode

What happenned: Anet doesn't expose parameters on connect, and even with M503 the gcode generated is not standard

What did you expect to happen: Automatically call M503 on connect, and convert anet a8 firmware into a marlin compatible code with the M2* command.

If relevant, upload the PrintTimeGenius log and any problematic gcode files (you might need to rename them).

Here the output

I have never seen firmware like this. Anet A8 does not use a normal Marlin firmware?

[eyal0]

Output appears similar to this:

https://github.com/jeremy-prater/Repetier-Firmware-ANet-3D/blob/master/src/ArduinoAVR/Repetier/Communication.cpp

It is repetier firmware

[vincent-ogury]

It support the reprap command. I don't know if Marlin calc would work properly on this machine.

The problem is that I can't change the firmware. It is lock by the constructor.

[vincent-ogury]

I can add on connect the proper M20* command and check if it fix the computation. I will give it a try.

[eyal0]

Because it is a different firmware, the simulation might not be accurate! Let me know.

If you type in all the M commands 200-206, PTG will notice.

[vincent-ogury]

I have set the config manually in the config. The calc takes care of it and don't remove it.

So I will try to see if it is accurate enough. Also it is hard to be sure I have put the right parameter with the right gcode based on the output of the repetier firmware ...

I close it, not a marlin firmware.

[eyal0]

Was it accurate?
