I read that someone went from Qidi 7.8 to Sailfish 7.7 and was able to mitigate all of this shuddering simply by flashing the official firmware. My thoughts are that Qidi is using a VERY dated copy of Sailfish (not a 7.7 fork), that might even be slightly broken...

I am going to attempt to flash to Sailfish 7.7. Can anyone recommend a USBASP ICSP Programmer that will do the trick?
Do not try it I know of no one that has successfully loaded the official version of Sailfish on Qidi Techs that come with there own version of Sailfish 7.8.
You will brick your board.
If your having acceleration problems there is something else going on. Do you have acceleration turned on from the Qidi Tech screen menu.
Also use the startup script found here with S3D http://3dprintboard.com/showthread.p...Startup-Script
