Some of these steps have to be performed in a particular order, others have a certain degree of flexibility. The square should be 25 x 25 mm with it's height scaled to match the target layer height. To test how strong the transparent parameter really is, I printed tensile samples in horizontal and vertical orientation as well as impact specimens to get an idea about the toughness. I could probably bump the temp up to 275 and increase my flowrate to 50-60mm3, but I'm not sure if it's worth it due to the reduction in print quality. A thicker line width allows for higher volumetric flow and stronger parts, but affects fine details and sometimes causes defects at sharp corners. For best results, we recommend using a vacuum with a HEPA filter to vacuum the shop regularly. Select Pass 1 in the Calibration menu. 5. International ResellerS.

In this CNC Kitchen blog post ( Nozzle Spacer - CHT for Volcano Hotends — CNC Kitchen) Stefan has a graph comparing commanded vs. 3720 . 200mm 3/s (for volumetric test 1. g. Fixing my flowrate through a slicer seems much more suboptimal than printer config/firmware so I'm wondering what my options are here as I've also already done pressure advance tuning. Very high layer-heights just won't do, but having very tight layers will also increase the number of places where something can go wrong. Somehow the best performance showed the high-flow spacer plus a regular V6 nozzle that only showed small flaws at 40 mm³/s but then also abruptly failed at 45.
