Hi Charlie. Very strange. Doesn't look like stepper driver thermal shutdown. That's normally a complete stop and restart. I can't remember which Arduino board you are using. Maybe you're delta...

Cheers for the reply Andy. I'm using Rumba with DRV8825 drivers at 1/32 microstepping. It's printing from SD card direct from my full graphics LCD. I've tried reducing the delta segments down to 100...

Hi Charlie It's got to be worth a try. It's a bit of a job pulling two jumpers off every driver though. My set up is identical to yours and I run 200 delta segments and 1/32 micro stepping. The only...

Hi Charlie Just a thought. My Rumba came with a spare SD shield. I assume yours did too? Try disabling your graphics controller in firmware and use the SD shield instead. You can initiate the SD print...

Hey Andy I might try going down to 1/16 and run a print as see what happens. The stuttering seems to happen on all prints but its especially obvious on the spiral vases. Also another point i forgot to...

Looking at that video Charlie the stuttering/stopping would likely be those DRV's - I've seen a few videos of the same thing. It's something to do with the board needing to pause to catch up or...

It might pay to check if its related to the resolution of the prints. If a circle has 20 segments, thats pretty blocky and easy to process, but if a circle has 5000 segments, the arduino is going to...

My borosilicate was easy to source as I used a square mk2 heat bed. Round would have looked much better though. At less than £20 for the heater and the glass it was too cheap to ignore and it works...
