For dual extrusion prints please implement the feature to turn off an extruder when it's done w/ its layers so it won't ooze onto the print while the other extruder continues its build.

I looked at the gcode and it appears that after an extruder is done with its layer that it only retracts by the Dual Extrusion Switch Amount and not by Retraction Distance + Dual Extrusion Switch Amount. Please confirm the retiring extruder only retracts by the Dual Extrusion Switch Amount because I am trying to avoid jams in my hot end which would occur if it retracts too great a distance.

The gcode for both TYPE:WALL-INNER and ;TYPE:WALL-OUTER shows after the hot end is done w/ its layer. What kind of walls are these? What's the name of the setting that controls these?

Thanks you.

I'm running dual extruders. Is there a way to assign an extruder to a part? Otherwise I need to switch bowden tubes to assign the extruder.

Here's some of my print settings: Nozzle Size: 0.5mm Bottom/Top Thickness: 0.84mm Shell Thickness: 1.05mm Filament Diameter 1.85mm And here's a pic of the non-uniform top surface: Does Nozzle Size need to divide evenly into Bottom/Top Thickness to get a uniformly looking top surface?

Hello Daid, i looked at the code, but it wasn'readily apparent which value i need to change to keep the build angle of the Ooze shield at 10% or less . Can you please give me a hint?

Daid, Thanks for the plug-in. Trying it out now; however I would prefer to tailor it to each nozzle. For example, I like to print HIPS at 220C and Ninjaflex at 210C so I need a separate Dual Temp Extrude / Cool setting for each extruder. Is this possible?

...so basically what I'm asking is, how do I cool down the non-working extruder while the working extruder is building the print? I think this will also help to eliminate oozing that the Ooze shield doesn't catch .

Thanks, 0.05 mm error is a good number to work with. I've been spending half my time trying to get good prints with the large error on my TAZ 4.

Thanks for the info.

...and I have nozzle size set to 0.35 mm.

Thank you for the suggestions. So I did not see the extrusion width variable in Cura's output gcode so the 0.44 mm first layer width was a calculated value by looking at the gcode finding two parallel lines and adjacent loop segments, comparing the coordinates, etc to make the calculation. The 0.44 mm first layer width is not a measurement by eye, sorry for not making this clear in my postings. My layer height is 0.22 mm and first layer height is 0.3 mm are data values I entered into Cura's respective fields. I am using a TAZ 4 with Cura 14.09 which is Lulzbot's Cura edition: https://www.lulzbot.com/cura

by the way, it's the first layer that is giving me a 0.44 mm extrusion width.

My nozzle size is 0.35 mm, but the Cura's gcode is giving me an extrusion width of 0.44 mm. My layer height is 0.22 mm and my first layer height is 0.3 mm. Any ideas why my extrusion width is coming out to 0.44 mm with a 0.35 mm nozzle?

I have a TAZ 4 that has about a 0.16 mm difference in height between the center of the bed and the four corners, so in other words there is a significant bulge in the center of the bed. This bed height differential makes it difficult to successfully print all over the bed. So I'm thinking about buying an Ultimaker 2. What is the typical high to low bed height difference for a UM2 bed?

There is no explicit field for me to enter the extrusion width, so I'm wondering how Cura figures it out? Also, is the formula for extrusion width different for the first layer vs the other layers?

Thanks for the suggestions. I also want to try to move the nozzle to x, y home using G1 X0 Y0 F1500 during extruder switches while I cool the previous nozzle to 60% temp as the new nozzle warms up. What is the generic variable and its formatting that I can use for extruder temp in the preSwitchExtruder window that will apply to both extruder 1 and extruder 2. Also wondering if there a list of these generic variables?

I'm using a dual extruder with my TAZ 4 printer, one has red ABS in it and the other black ABS. When the black ABS extruder (#2) is idle it is oozing onto the red print (see 3 pics at links below). I have Cura's "Retraction / Dual extrusion switch amount” set to 16 mm with retraction speed of 25 mm/sec and I'm using the Ooze shield. How do I eliminate this ooze that is destroying my prints? What settings do I need to change in Cura? https://www.flickr.com/photos/130315391@N08/15779180373/in/photostream/ https://www.flickr.com/photos/130315391@N08/15780572213/in/photostream/ https://www.flickr.com/photos/130315391@N08/16214377889/in/photostream/

Are you going to offer the option to change the Ooze shield build angle? Even just two options, one vertical and one auto (which would be current configuration) would be nice. Someone else also had the issue where the Ooze shield collapsed and delaminated from itself due to its current aggressive build angle setting: http://e3d-online.com/index.php?route=extras/blog/getblog&blog_id=20 " The ooze shield is a bit ambitious in the overhang angles that it tries to achieve and often collapses and/or delaminates (as seen in the above image). In slicer the ooze shield is vertical all the way up - this makes it easier to print but it is now further away from your object. Ideally we would have a Cura-like shield with a configurable maximum-angle. "

...and will it work w/ TAZ 4 printers or only w/ Ultimakers?

Does this work w/ dual extruders yet? A lot of my prints are done w/ dual extruders; hence the reason for my question.

Please add the ability to change Fill Density (%) at a given height or layer.

How do I change the Ooze Shield Build Angle? It's current settings cause it to build itself up at too great an angle and it starts to fall apart and tip over and I don't know where to change its build angle.
