* For best results printing PETG, '''do not use the Filament Fan'''. (Print with the Hotend Heatsink Fan '''only'''.) When the Filament Fan is used, expect layer separation problems. When printed without using a Filament Fan, PETG has '''exceptional''' layer bonding. | * For best results printing PETG, '''do not use the Filament Fan'''.

* As a filament type, PETG is terrible at things like bridging. This includes you might need just a bit more top surface over infill to get a smooth outer layer. | * As a filament type, PETG is terrible at things like steep overhangs and bridging. This includes you might need just a bit more top surface over infill to get a smooth outer layer. (Or just use a slightly higher infill %.) | ||
* | * That PETG likes to to buildup on the '''outside''' of the print nozzle is a major problem with this filament type. This has a lot to so with how all PETG is "stringy". (Some makes/brands are worse than others.) So as the hot nozzle moves through any spiderweb thin strands between printed parts, PETG filament builds up on the nozzle. (And eventually may drop onto the print, as a possibly print ruining blob of plastic.) For that reason, any print that could be described as a "highly shaped bock of plastic" should work well. But prints where the head constantly moves over open air -- with no plastic under the nozzle & creating many strands -- are more likely to fail. | ||
* These settings use a 0.35mm line width out of a 0.4mm nozzle, '''instead''' of all the other overlaps which would also contribute to PETG trying to build up on the outside of the nozzle. | |||

* Had repeated/ongoing LAYER SHIFT problems with a large "lot of movements" print. | |||
** Snugged the screws to hold the plate on, as it was moving. | |||
** Tightened the printhead gantry screws. Several have nuts pulling through, so '''need to glue that part of the printer'''. | |||
** Retention both belts, by adding a printed piece onto each belt. | |||
** Still getting some Layer Shifts, so will have to try 120mm/s travel speed next. (Instead of 200mm/s) | |||
* Discovered the Print Bed Plate is no longer flat. (Small high area, centered on X-axis & bit behind Y-axis.) | |||

PLEASE NOTE: These connectors are '''extremely difficult''' to crimp in a manner they work. So at least '''double''' the crimp-connector parts are needed to get solid/working connectors. | |||
