Printing at 200C, my house is really cold and it didn't do as well at 185c.

Layers aren't sticking together very well.

.4 nozzle and 1.75 filament that I've measured at 1.66 and have put into slicer.

Using slicer/pointerface.

I think perhaps my speeds are too fast and causing it not to get enough plastic out?

Printer is based on an I3.

What are some good settings for the different speeds?

Looks like a couple of issues. Speed and/or acceleration too fast and/or stepper current too low, causing skipped steps and shifting in the layers. Inconsistent extrusion, caused by stepper current too low and/or hotend problems. Could be other reasons as well.

You could try a max speed of 50 mm/s for printing and 100 mm/s for travel moves, if everything else is set properly your printer should be able to handle that. If not, try lowering your acceleration settings some as well.

Think I found the problem. The settings weren't carrying over from slicer to pointerface. I just exported them and loaded them in pointerface. I think that'll fix it. So yeah, pretty much a big part was what you were saying. I had adjusted those speeds but it still wanted to go fast, print from a .5 nozzle and use 3mm filament.

Thanks!
