Well...
I think i was happy too early.
Just started a print and it does it again. It doesnt do it when moving the axis in Ponterface, but when I started the print from SD card, it does it again.

Hi Bolec,
Lowering Delta segments per second cuts down on the calculations. You may not notice much difference in quality with a lower value, to a point.
So, you have a Mini Rambo - that's an 8-Bit Arduino. Are you using a Full Graphics display?
Depending on your configuration (steps per mm, printing speed, move speed) there may not be enough processing power to calculate the delta math and output the steps fast enough, and and run a graphics controller. The same issue occurs with RAMPS and Graphic controllers on Deltas.
If you are running one, you could comment it out in firmware and try the test.
I started with an 8-bit controller (Rumba) and had the exact same issue due to high step rates caused by .9 degree motors and smaller drive pulleys - I was running non-graphic display. (Using a Smoothie now, not looking back).
That's all I can think of at the moment. Hope that helps.
