Hello! I am currently using the wades extruder "http://www.thingiverse.com/thing:1794" with the budha style hot end that I got from "http://gadgets3d.com/index.php?route=product/product&path=62&product_id=77" The maximum print speed I can get is up to 30 mm/s, anything higher then that and the hotend jams. The filament starts to buckle between the hobbed bolt and the hotend or the hobbed bolt shreds the filament. I am using 1.75mm ABS filament with 0.5mm nozzle. Temp is 230 - 240 degrees on the hot end. Filament was bought on eBay, it was on the cheap side of filament... What can I do to increase print speed? What is the absolute best hot end in the market right now? (if there is such a thing...) Thank you so much in advance! :) https://reprap.org/forum/read.php?1,245361,245361#msg-245361 Thu, 16 Jul 2026 21:50:26 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,245361,246447#msg-246447 https://reprap.org/forum/read.php?1,245361,246447#msg-246447 -------------------------------------------------------

What are your firmware accel settings?

How bad is your overshoot?

I've been wrong before, but if you have gotten good prints at that speed on your doodle 3, please post a video.]]> cope413 General Wed, 18 Sep 2013 11:08:19 -0400 https://reprap.org/forum/read.php?1,245361,246422#msg-246422 https://reprap.org/forum/read.php?1,245361,246422#msg-246422 -------------------------------------------------------

Set your PID correctly and you'll never have over shoot...
Why are you still using PEEK? I don't understand why people still use that..it has melting temperature way too close to ABS's. Go get a full metal extruder.

Probably too cold

Are you sure you are printing at "230°C" ? It depends on the thermistor you are using. eBay ones tend to be really really bad.

Yes you can reduce the speed. Like you said, it is all about the "melting time". People tend to turn the temperature higher when printing faster to compensate the reduced amount of time spent in the melting chamber

What printer/extruder are you using? ]]> tleneel General Wed, 18 Sep 2013 09:55:10 -0400 https://reprap.org/forum/read.php?1,245361,246413#msg-246413 https://reprap.org/forum/read.php?1,245361,246413#msg-246413 > but it's already at 230C. If I set it anything

You can change your MAXTEMP in firmware. I put mine up to 245, but set to 238 or 240 in order to minimize overshoot. Hopefully wont destroy the PEEK.]]> grumpenstein General Wed, 18 Sep 2013 09:46:41 -0400 https://reprap.org/forum/read.php?1,245361,246261#msg-246261 https://reprap.org/forum/read.php?1,245361,246261#msg-246261 aduy General Tue, 17 Sep 2013 21:17:27 -0400 https://reprap.org/forum/read.php?1,245361,246235#msg-246235 https://reprap.org/forum/read.php?1,245361,246235#msg-246235
I wanted to try at a higher nozzle temperature, but it's already at 230C. If I set it anything higer than that, sometimes it goes over 235C, which is the saftey celing temperature in my setup, as a result of fluctuation and my printer shuts down. In other words, higher temperature isn't really an option.

After reading some notes here, I wonder if I would have a better luck if I reduce the speed - even at the same temperature, the filament will have more time to metl in the hot chamber. You know, it's the opposite case of having to increase the temperature a little bit when increaseing the printing speed.

I know it always sucks to decrese the print speed, but I would be happy to be able to use this whole spool of filament. I do a lot of overnight prints (= I start printing, watch the first couple of layers to make sure everyting is good, and then go to sleep), with which it doesn't make a whole lot of difference wheter it took an hour to print or three hours, since I would only able to check back 7-8 hours later anyway.]]> Yamster General Tue, 17 Sep 2013 18:25:50 -0400 https://reprap.org/forum/read.php?1,245361,246224#msg-246224 https://reprap.org/forum/read.php?1,245361,246224#msg-246224 -------------------------------------------------------

Incorrect, I do 120mm/s perimeters and 200mm/s infill regularly on my Solidoodle 3.]]> greenman100 General Tue, 17 Sep 2013 17:36:11 -0400 https://reprap.org/forum/read.php?1,245361,246199#msg-246199 https://reprap.org/forum/read.php?1,245361,246199#msg-246199

Make sure you have the right temperature, put it a little higher if you go faster. Make sure you have enough pressure.]]> tleneel General Mon, 16 Sep 2013 10:56:45 -0400 https://reprap.org/forum/read.php?1,245361,245413#msg-245413 https://reprap.org/forum/read.php?1,245361,245413#msg-245413 www.vanguardinnovations.us]]]> aduy General Sat, 14 Sep 2013 20:16:43 -0400 https://reprap.org/forum/read.php?1,245361,245361#msg-245361 https://reprap.org/forum/read.php?1,245361,245361#msg-245361
