Voron Cube 200% Test

These are some of the 1st prints on this machine since the rebuild. I can't say I am pleased with the results. With everything new comes some issues. This is Sunlu ABS, 265C, 700mms commanded, 30K acceleration, 40 SCV. These motors (LDO 2504) have terrible VFA from 100-150mms. This particular print is a constant PA value and variable SCV based on feature ranging from 20-40SCV. Acceleration is variable from 20K to 60K. 20K for top solid, 30 for walls and 60 for infill. Infill i s adaptive cubic @ 5%. Total time ~22 minutes @ 200% size. Measurements: Keep in mind that with PA not giving a sharp corner, I had to pick and choose where to measure to avoid any bulge. X-59.83 Y-59.91 Z-59.92 ID circle top:31.4 - should be 32.4 I.D. second hole above 1st- 25.4 - should be 26.4 There was compensation entered in slicer for vertical holes at .522 (I missed resetting to zero). XY being not the same means the skew is off. Not much, but it's not printing entirely square. It's close, but can be better for sure. For starters, the fan speed is way too high for this speed. Discoloration on the top surfaces is the sign! This is the crux when printing higher speeds, too much fan and layer adhesion issues, too little and melting. Layer stacking is not right and I have some VFA on smaller circles where the speed is too low, probably in the bad range of speed for the motors resonance. I can see some lines in bad lighting, typical for 3DP, seems worse than usual, but this part is a bit faster than I print normally. Filament diameter can affect this, so I will disregard. PA is such a problem for some reason. There are those small ripples in the corners and flat surfaces. I can see some irregular surface finish where pressure advance kicks in during the starts and stops. I can lower the PA, but the corners suffer. Too low of PA and the corners will get those squiggly lines. There is an improvement in the shake of the machine, probably due to the added weight of all the panels and more frame. Running the higher square corner doesn't seem to be as loud/violent.
