ok, so accelerate slower compensates for the lag. Accelerate faster compensates for the lag.

I would run slower if i needed to have lots of stops and starts. I still believe the ideal is to print at a constant extrusion rate without ever lifting the nozzle, retracting, or any of those other types of optimizations. The up! mini was a good example of that kind of implementation.]]> Simba General Thu, 28 Feb 2013 13:28:36 -0500 https://reprap.org/forum/read.php?1,187936,188289#msg-188289 https://reprap.org/forum/read.php?1,187936,188289#msg-188289 Traumflug General Thu, 28 Feb 2013 06:20:09 -0500 https://reprap.org/forum/read.php?1,187936,188077#msg-188077 https://reprap.org/forum/read.php?1,187936,188077#msg-188077 konwiddak General Wed, 27 Feb 2013 12:25:11 -0500 https://reprap.org/forum/read.php?1,187936,188075#msg-188075 https://reprap.org/forum/read.php?1,187936,188075#msg-188075 -------------------------------------------------------

I never realized this. How does acceleration affect print quality, such as to make a blob? I would have though the faster the acceleration, the better, especially considering the delay between extrusion steps and actual extrusion from the nozzle, that you'd want to reach a fixed speed as fast as possible?]]> Simba General Wed, 27 Feb 2013 12:11:00 -0500 https://reprap.org/forum/read.php?1,187936,188013#msg-188013 https://reprap.org/forum/read.php?1,187936,188013#msg-188013 konwiddak General Wed, 27 Feb 2013 06:52:22 -0500 https://reprap.org/forum/read.php?1,187936,187972#msg-187972 https://reprap.org/forum/read.php?1,187936,187972#msg-187972
I remember when the Ord bot users were first testing their bots on buildlog.net, thinking their machines were going at 1m/s because that's the value they gave slic3r! :S]]> yydoctt General Wed, 27 Feb 2013 03:23:52 -0500 https://reprap.org/forum/read.php?1,187936,187965#msg-187965 https://reprap.org/forum/read.php?1,187936,187965#msg-187965

Type of 3D printer: 3D Printer
Print Speed: 120mm/s (infill) I think I can go faster than that
Layer Height: .25mm
Type of Plastic: PLA]]> nefermu General Wed, 27 Feb 2013 03:02:37 -0500 https://reprap.org/forum/read.php?1,187936,187949#msg-187949 https://reprap.org/forum/read.php?1,187936,187949#msg-187949
The problem isn't "print speed" it is "plastic output." Ultimaker can move 350 mm/s (so can prusa makergear2, incidentally). However, you couldn't flow fast enough or accurate enough to make that speed worthwhile.

If you wanted to truly print super "fast" as in 200 mm/s, you would need to make the layer heights 100 microns, and then print at a constant extrusion speed, because the printers can not accurate convey changes in extrusion speed at these speeds. The small Z height is necessary to enhance sticking and prevent other "globbing" issues due to surface tension at high print speed with a pseudoplastic.

Truly, the extruder gets at most 8 watts of power (from 15W or more) efficiency converted to melting plastic. What does this mean for you? Very very slow flow rates. In fact, 15 mm^3/s of plastic (thats 15 MICRO liters) is the limit, i.e 6.5 mm length of 1.75mm diameter filament per second.

An average print may be 40000mm^3 of plastic (40 mL/ ~grams) i.e. 1/25th a 1kg roll of filament. So at max speed (15 mm^3/s), this part (40,000 mm^3) is a 45 minute job, no matter how fast your gantry can move.

So there's the real limit, and why FFF needs a major revolution to pickup the pace and compete with CNC, injection molding, and now DLP 3DP.]]> Simba General Wed, 27 Feb 2013 01:49:21 -0500 https://reprap.org/forum/read.php?1,187936,187936#msg-187936 https://reprap.org/forum/read.php?1,187936,187936#msg-187936
