ATMEGA blew up

Now that's what I am talking about. Let's settle this like gentlemen. Challenge accepted. I will use my reworked geeetech i3 Pro B that uses an SKR 1.4 turbo with TMC2209 drivers running in UART. Only thing is I only have PETG to print with these days. I will prove my time with a picture of the print and display at the end of the print. brb.

Oh no. Well Roberts_Clif my print time is behind you, sir..

The item printed out well. I might have been able to get a better surface on the print if I dropped the nozzle temp 5c but no worries. It looks nice..

So I am embarassed at this point. Obviously. Hat's off to you and your printer tuning capabilities, buddy. I will now chase what you are doing and identify flaws to fix. And TY for pointing me off in that direction. Mine printed in 1:51 or 111 minutes whereas your printed in 1:38 or 98 minutes. Yours printed 13% faster than mine. So now I reprint..

I truly believe that the print times are so close that we both won.
Both of us have figured out how to print the very best in the fastest time.

I wish I could get a faster print time and you probably also want a faster print time.
I can print faster though the models start look not so well and the the layer are not well laminated.
Have even upped the nozzle temp with the printer speed helped a little though still sacrificed the model quality and lamination even printing in a heated enclosure.
I have never had any problems with my current controllers other than the two I killed the stepper motor drivers IC chips on.

Did we loose you EmperorShaohao this was your thread and we still want to help you just got side tracked.
