I’ve been using the Vertex for 18 months now and I thought I’d got it setup quite nicely. I’ve used various colours: natural, grey, blue, red, yellow - PLA.
I have a 6 hour print that I have already printed with yellow but I want white for the final. I received new Velleman white PLA filament this week and started to print yesterday. I use S3D for slicing and OctopPi for printing.
I have the same settings as previously. I cleaned the print bed (I’ve been using Zebra Plate successfully since August last year), and recalibrated Z. I had to stop the first 2 attempts as the brim wasn’t sticking at all. I recleaned and recalibrated this morning, but the results are the same. I even pulled the brim from the print bed as it was interfering with the printhead. I hoped it would stick as it progressed but I just cancelled on the 2nd layer - the print is really poor. Now on layer 2 it can’t even lay down the walls properly
Does white filament need different settings (eg flow rate - I still have 95%)? PLA temp is 190 as always. Cooling is 100%.
I will look at the S3D tips again https://www.simplify3d.com/support/print-quality-troubleshooting/ but as nothing has changed in the settings I wouldn’t know what to change. I noticed that the extruded filament does look thinner than previously, and the blob extruded at the home position after heating is also half the size of the blob produced by other colours. Could it be a bad batch, or maybe I should have cut off more from the start of the spool? Normally I check for brittleness at the start but I think I didn’t bother so much this time.

I’ll remove this filament and do the first layer or 2 in yellow again to compare.
