I’m having problems printing large models (which relate to the edges of the x-axis), closer to the edge of the x-axis extruder mechanism starts pounding and plastic ceases to be supplied to the nozzle print without Teflon tubes, often the case is solved by the fact that there is too great an angle plastic tilt if it is to align the hand - tapping stopped. But are there any other solutions to this problem (Teflon tube already ordered, on the way) Big thanks for comments to all! It’s works!
I think this solution does not solve the problem with unsticking permanently. Yes, a short pipe creates resistance. But plastic is melted. Why did he need so much force to come out of the nozzle? Looking at the picture, I see that it is simply not where to go, there is no gap between the bed and the nozzle. In the first print layer it need a gap to plastic is not left on the edges of paths and touched the adjacent strip. This will means that the gap is ideal.
Looks like there is too much extrusion or the nozzle is too close to the bed. That is why you see the ‘waves’ of filament and it could also be the reason why you hear the stepper motor make a clicking noise. Could you see if it helps if you increase the Z distance between the nozzle and the print bed?
