So, the images below show the problems that I’m having. The perimeter walls print great, the top and bottom are great, even between layers I’m great. The infill looks like garbage though. I get that it’s inside the model and that no one can see it but on my larger prints it makes the model weak when squeezed. I have printed hundreds of models with no issues at all. This has been every print for about the last week.
I stripped the print head, cleaned the nozzles, cleared the motor teeth, replaced the extruder tubes and re-leveled my tray. I thought maybe it was teh flash print software since it updated recently so I even uninstalled that and used my back up file from back in November that I’ve been using with no issue. Any suggestions on what is causing it or how to fix it would be greatly appreciated!
Printer: Flashforge Dreamer
Material: 1.75mm PLA
Layer Height: .4mm
Infill: 5%
Nozzle Temperature: 220°, 215°, 210°, 205 (tried all of these)
Tray Temperature: 50°
Hey,
is that possible, that your infill print speed is way to high, compared to the perimeter print speed?
I dont know which slicer you use, but I think most of them can set different speeds for infill / perimeter, etc.
So, try to lower your infill print speed, and you’ll see if it gets any better.
Good luck!
Thanks for the reply! So, I kept looking after I posted this and I found someone who had the same issue. They found out their speed was too low for their layer height and had to speed it up. I played with the slicers default settings instead of the custom I’ve been using and found that at my layer height it should be about 20mm/s faster. Apparently it cools faster at .4mm and needs the added speed to adhere. My printers slicer (Flashprint) only has two speeds though, print and travel. I plan to increase the print speed and leave the travel where it is to see what happens. Unfortunately I don’t have access to the infill speed even though it uses two different speeds for the walls and infill. You can watch it slow down for the walls and speed up for infill. I’ll post back with what happens. Fingers crossed it works. I’ve wasted two rolls of filament trying to print things that end up too weak and break apart coming off the tray. Haha
Sounds like you don’t have active cooling… That would really help.
