Good. I would try and print the fan duct first though.
Will do, it seems the fan duct needs to be made from ABS, not PLA, so will need to order a roll of ABS to make the fan duct.
I tried the pilot again after calibrating the nozzles… bad things happened, he doesn’t have a head!
The temp was 205, thought I’d increase it a bit to try and remove the broken layering. But that didn’t seem to work that well! if anything it made the layering even worse. It comes apart in layers easily.
Definitely need the cooling!

I use a PLA printed cooling duct and don’t have any issues, though I do need to replace it sometimes because it does warp from the heat overtime (something like every 6 months or so.) I printed my first duct very slowly, it wasn’t prefect but it was good enough to make it so I could print a second duct at a normal speed without any troubles and since that quality is only getting better.
It still look like you are printing too hot, and it could be that you are printing to slowly now too. It sucks but for the first little while there is a lot of trial and error in getting the printer’s settings figured out. On my printer I generally get the best layer results when my feedrate is between 50 and 70 mm/s. Try changing your infill from honeycomb to rectangle. It will save time and filament (and be just as strong with less vibration during your printing.) As for removing layers during a print that will more often cause the print to fail than save it. It’s better to stop the print and start over, it sucks but sometimes that is all you can do.
Hi guys for anyone reading this post. I have finally got good quality prints by doing the following…
- Install Makerware 3.8
- Print on standard settings, but change the following values, Extruder temp:222c for the PLA that comes with the printer, and Setting minimum layer time to 30s.
- I’ve left the filament diameter at the default setting (1.75) - although the filament is 1.79. Changing to 1.79 doesn’t seem to make a difference. I’ve also left the extrusion multiplier at the default of 0.93.
I’m now printing perfect pilots every time.
It seems it was a simple case of raising the temp for the PLA to 222, and slowing the layer time to 30s. Makerware 3.8 Beta is much better.
I’m sure that ensuring the printer isn’t over or under extruding is important, but doesn’t seem to be a contributing factor in the pilots i’m doing. I probably need to revisit the cubes as they are 19mm across, not 20mm. So when i come to needing to print accurately sized parts that slot together, getting it accurate will be important, but for people these settings seem pretty good.
Makerware 3.8 gives you the ability to change all the settings without having to use proftweaks.
I’ve semi perfected printing in PLA now. good enough for what I need at least. They are no works of art, but they’ll do nicely. Im now moving to the dark art of ABS.
Quick question. Which version of makerware desktop do you guys use? Since upgrading from 3.8 to 3.9, the left extruder has started working, but for some reason i get another structure next to the main piece… and ideas?
