Nightmare start

[d43d]

So definitely gettin there! I just did a little test.. solid disc type shape.. 14mm diameter by 5mm.. (same as previous tests) and with the filament loosely cable tied to the main cable run, the filament no longer slipped/tugged at all and was smooth.. This coupled with the slower speed 40mm/s and travel at 80mm/s, has gotten a good result.

There still is a couple of issues..
1) On every circular rotation there's kind of an jerky and so that is reflected in the 'seam' type effect along the edge.. Is this normal? A mechanical fault? Slicer fault?

2) Then the top is a little bumpy at the end (or start?) of each line.. Is this a cooling issue? Is this where people say to use a fan to cool PLA? Is this related to issue 1 perhaps?


Thanks for the tips.. I've not levelled my nozzles yet.. still just using the right nozzle.
What is the advantage of that feeder upgrade?
Has anyone done the supports for the back rod upgrade as described here? https://www.youtube.com/watch?v=lXOmesjMbfU (EDIT: Having read another thread, it appears these are not needed)
Also I've heard that lithium grease is good to stop noise? Anyone done this? Mine's only noisy really when it raises the bed..
