SO I have built new CoreXY printer. It prints great, but I have a problem. Heated bed is having hard time heating up. Though on Marlin 1.1.9 on MKS Gen_L I have no problem. I have set Bed max power to 255 and enabled PID and autotuned. But whenever I turn on heating the diod in board not light up all the ti, but blinks indicating not full duty cycle and voltage at terminals are fluctuating from 6

No, plastic is going out from nozzle hole, from where it should. But too much. On my delta when nozzle is heated up there is about an inch of plastic going out due to gravity and ect, but here it just goes and goes for 5-7 inches. I checked temperature using water (dont have ir heat gun), it boils off is I tuch heater block with wet brush at 100-105 degree set.

But when I heat nozzle up to about 190C plastic starts to ooze out and wont stop for minutes. Even if I retract 3-4 mm there is still plastic coming out. I have checked, upper part of V6 print head, radiator, is room temperature to tu

It is Kossel Delta Mini. I already solved this problem. I still cant belive that this was the cause. It was a loose screw on one belt pulley! The behaviour was so consistant and peretable that I could not even though about it! Tighten all up and now its printing just great!

I have some strange problem. When print head moves to region with negative Y coordinates the print head is lifting up and some times movet to side. And when it moves back it goes down agait EXACTLY same height so it continues to print fine, retaining leveling. Tried two boards, MKS-mini and MKS-Sbase, cheched stepper motor connection - everything is fine. I dont get it. What could be the problem?
