Controller Board

MSK TinyBee

Machine Description

Using MSK TinyBee to control four motors. UART is used to connect with an external serial display. I created a serial monitor software for that external display and I can type commands to control the board. Skype_Picture_2024_08_08T14_06_01_607Z

What happened?

I have a short G-code file stored in spiffs and execute the code by "LocalFS/Run=/2.nc". However, while running, messages like "Low memory: 13242 bytes" showed up randomly and the size was descending. After reaching 0, the board restarted and the original task was somehow aborted.

Other Information

If I use a shorter G-code, I do not have such issue.

bdring commented 2 months ago

Update the firmware. v3.7.17 addressed a memory issue.

zizheng1 commented 2 months ago

Thank you! I will update the firmware.

MitchBradley commented 2 months ago

In addition to the version problem, there are other problems that can happen when running long gcode files from localfs. Accessing FLASH as data can interfere with interrupts, which can cause problems with realtime step generation. We recommend using SD cards for gcode files.
