High Speed Tune with PLA

[drwho]

We have a been tuning and test this machine for some time and have finally gotten to a point where it is running great. A fascination of mine has always been speed so we have upped the speed on Zoe (our printer). We only recommend this for a very well tuned printer, as speed amplifies everything. Also quality is compromised with speed, as well as a tendency to lose temperature faster at the tip. We have a e3d v6 w/ volcano 40w heater and a .4mm tip.

We are currently running 90mm on all except the following:
external perimeter = 30
top infill = 60
bridge = 30
gap fill =30
First layer = 30

I have a feeling you can probably go much faster.

The arms on my printer are ~330mm hole to hole, she hums along with the following settings for ABS.

100mm/s outside perimeter/skin
130mm/s infill
70mm/s bottom layer. (Any slower and it globs and clogs)

240c hot end, 100c bed/ 50c heated chamber.

My Quality settings are

60mm/s outside
100mm/s infill
70mm/s first layer

235c on the hot end/ 100c bed /50c heated chamber.

Is that tinfoil under your glass?

It certainly does look like tin foil. I guess its a makeshift heat spreader.

I agree with ABS being able to handle faster speeds. We have had prints into the low 120mm/s in ABS. PLA on the other hand, at least this filament, has a much different adhesion profile. It takes loner to "set" when cornering. It will not stick on corner above about 30mm/s.

I strongly suspect that the filament is the culprit because the ABS that we have from the same company is shitty. Until we get better PLA this is where we sit. JaguarKing I always like to see people that are pushing the speed limits of 3dp. How fast are you printing in PLA? How about other filaments?

Under the glass is actually aluminum foil. It was initally used for a large print that was pulling up the foil helped spread the heat more evenly. This works fine until I get around to ordering a silicone wafer.

MY printer is a bit of a one trick pony. I printed less than 10m of pla so far so cant say on the speed. I just dont like pla plastic though. Not yet anyway. I prefer stinky ABS here. FYI, true speeds come from larger nozzles and not movement, but that cuts down the resolution quite a bit. Check out this acident and the results.
