I have a little probelm with my beloved Anycubic kossel linera plus (Delta) printer.
It could print smoothly with it's original ATMEGA 2560 based trigorilla board with 2004 LCD.
But I upgraded it to Arduino Due + Modified Ramps with Full Graphic LCD.
Since then it is not perfect It is stuttering sometimes, mainly when I am navigating in the menu system.
I always printing from SD, that's why I wired the SD card to hardware SPI and wired the LCD with software SPI.
I know is a wellknown problem. But I would like to know which is the best config, for taavoding this issue.
I tried to change the SD SPi speed, I tried full speed, half speed and 1/8 speed. But Noting changed. So the probelm is not related to SD SPI configuration.
Delta segmentation is 200 / sec, but I wouldn't like to decrese this value, beacuse the print quality is better with this value. (In the old config with mega this was 150/sec).
I tried to use Smooth movemnet but it is not work (in old config, with old marvin it works), maybe this feature is not supported any more.
I tried to use the SLOWDOWN option, but nothing change. Maybe it is not compatible with delta segmentation.
I try to change the u8glib from x1 to x4 But I don't know which should be better and whart is the difference.
Finnaly, I increase the block buffer from 16 to 64 and the problem almost completly dissapared, but not completly.
So, how I should config the LCD to get the best result. I thought DUE has enough power to handle it.
I could not find any good descreption about LCD config. I am not intrested in smooth animation on LCD, I only want to print with fast speed without stuttering.
Thank you for any help.
