Can anyone help me print a better Benchy?

[WLJayne]

Hey guys,

I've been playing around with the settings on my V3 for a few days and I have got better, but I'm still not happy with the prints. Can anyone suggest ways to correct the issues I'm having? This last Benchy was printed in PLA with:

Speed:
Temp: 210
Infill: 40mm
Inside Perim: 30mm
Outside Perim: 20mm
Travel: 300mm

Retraction:
Length on move: 5mm
SpeedL 100mm
Z lift: 0.1mm
Minimum travel: 2mm
No wipe

I'd really like to get rid of the blobbing, but I'm generally quite happy with the prints otherwise. Can anyone suggest something to try?

They used to have a visual troubleshooting guide. http://www.3dbenchy.com/category/troubleshooting/ That doesn't seem to be working anymore...

The other goto guides that you should reference are here:

Thanks, those helped a lot. Adding a negative value to restart extrusion has done a lot to fix it. Now I just need to find the right balance.

One day I will reach the Benchy limit. But it is not this day.

Do my dimensional accuracy calibration (link in sig) to make sure your geometry is set up just right. Whenever you get a new spool of filament, measure it using an outside micrometer in ten different places a foot or two apart, skipping the first few feet because they're usually somewhat kinked, and put the average in your slicer. Then, do step 1 of the dimensional accuracy calibration (single-walled box) to get it just right.

Change your retraction speed to 15mm/sec. You can also try a wipe setting. I find 10-15mm is very good on my E3D Cyclops. You might also want to try a retraction length of 3mm, but I'm not sure if your hot end requires it to be that short.

Make sure your extrusion temperature is not too high. It should take a little bit of effort to push the filament through. If it goes through with very little resistance, it may cause blobbing, which there is a lot of on one of those 3DBenchy prints.
