What are the print speeds/settings you guys use? I've been using this as highspeed:
Maximum Feedrates: 500/500/5/45 (X/Y/Z/E)
Maximum Acceleration: 9000 9000 100 10000
Maximum X-Y Jerk: 20
Perimeters: 150mm/s
Infill: 175mm/s
Travel: 175mm/s
Filament: MG94 made on a Filastruder, printed at 200C.
I doubt it actually gets to those speeds on most moves, though.
You guys?

Maximum Feedrates: 500/500/5/60 (X/Y/Z/E)
Maximum Acceleration: 9000 9000 100 10000
Maximum X-Y Jerk: 20

Feed Rate: 129%
Setting (actual with feed rate adjustment)
Perimeters: 120mm/s ( 154.8 mm/s)
small perimeters: 100mm/s (129 mm/s)
external perimeters: 80mm/s (103.2 mm/s)
infill: 110mm/s (141.9 mm/s)
top solid: 80mm/s (103.2 mm/s)
bridges 80mm/s (103.2 mm/s)
gap fill: 30mm/s (38.7 mm/s)

Travel: 150mm/s (193.5 mm/s)

Not sure what kind of plastic this is. It is natural and on a solidoodle reel but I got it from Tim.

Printrbot hot end @ 225C w/ fan

Sorry about the clicking in the video. I had my scraper on top of my case.

We should also standardize the layer height and extrusion width. I am assuming 0.3mm / 0.42mm for these parameters?

For me, yes.

I need my e3d to show up so I can push temps.

Wow. So where were we in our discussion of fail safe devices for hot ends??

Elmoret, it spikes to 100% while it heats up to 200, then goes back down to about 75 to 80%. I'll monitor it during my next print to see what it does then.

Sounds about right. That means that wattage isn't your issue, it's temperature. Basically, your PEEK will melt before you can get the hot end hot enough to melt the plastic at a high flowrate.

QU-BD's new extruder does 500mm/s max. To get that fast, they run nozzle temps over 300C. With ABS. Yeah...

Thanks Elmoret, very curious now, will check soon and post back.

In the temperature curve tab, at the bottom there's a plot. The green portion is what percent of the time the heater is on. Unless it's maxing out, dual heaters won't help you. Running hotter would, since Q=f(dT)

Are you at 100% duty cycle on your heater in Repetier-Host?

Re: Fastest Solidoodle in the west (or east...)

null@example.com (Briggs) — Sat, 01 Jun 2013 18:06:52 +0000

I keep my heat at 195 for high res low speed parts, and 205 for low res high speed, cause I know all the filament driving through will cool it down.

Re: Fastest Solidoodle in the west (or east...)

null@example.com (Briggs) — Sat, 01 Jun 2013 18:03:32 +0000

What I typically do for low res parts is set it to fly at 100mm/sec in slicer for perimeters, 125 infill, and then throttle up with multiplier in rh manual control until it starts skipping, usually at about 125 to 150 %. My only point jumping into this thread is that the plastic spits and sputters before my machine shakes itself to death! The thing with our machines (in case you haven't figured it out yet) is that there is a lot of variability from machine to machine. Your machine is dialed in elmoret! I just know that my hot end heat can't even keep up with my speed stated above, let alone yours. When I mod my new hot end I will use dual heaters. Then, elmoret, the race is on!!

Saying the extruder is the limit is fine and good, but how about some data - max speeds, temperature, filaments. Also, extrusion speed might be the limit on long parts, but acceleration becomes the limiting factor on shorter moves.
