Just Another GridBot v2 Build

  1. I am using Octoprint running on Intel i5 18.04 Ubuntu server. I happened to had a few very nasty serial port mid print disconnects. I had to switch to short 1’ USB cable from SKR kit (grrr… VERY unconvenient) instead of 5’ long USB cable I used initially. I also split 220V supply - the board and nozzle heater are powered via the UPS now, and SSR feeding bed heating pad is powered from a separate wall socket. No more disconnects for now…
    UPDATE: got another disconnect today after 5 hours of printing. very bad… My server and Octoprint installation are almost out of suspicion since they worked with my other printer flawlessly for many hours. Can be a PS problem?

  2. My firmware settings can be seen here:
    https://github.com/v0v/Marlin
    Only “SKR-1.4T-DD-no-BLTouch” (this stands for SKR 1.4 Turbo board with direct drive extruder and with Z-axis end stop, no BLTouch probe configuration) is updated to my actual settings.

  3. I am using E3D V6 chinese clone with 4010 cooling adapter for 4010 fan from Thingiverse.

    Unfortunately, it does not fit the v2 of Stewart’s Direct Drive Extruder mount. So, I am using v1 version. After I made this photo, I removed the BLTouch mount adapter on the left because if was acting like a X-axis stop. Will have to reshape Stewart’s v2 mount if I decide to stay with the direct drive.
