Cura2 LulzBot Edition Beta Testers Needed!

Look here for custom firmware, networked 3D printer hosts like OctoPrint, and more!

Control of heats for Extruder #2 in dual extrusion is completely whacked.

I did not notice yesterday when printing two materials that had the same heat profile.

Extruder #1 seems to work and switch properly between standby temps and printing temps.

Extruder #2.
1. When Extruder #1 is finishing the printing temp is correctly set to start warming up
2. As soon as it gets to within 10 degrees of setpoint(225 in my case) the setpoint drops to 200 degrees and starts to print the first layer.
3. Interesting that 200 degrees is not ANY temperature in EITHER profile for Extruder #2 or Extruder #1.
4. I manually set the temp back to complete the first layer.
5. When it comes time to print the second layer it again drops to 200--sometimes it does and sometimes it doesn't.

I'm printing off SD card.

Well I tried the latest and greatest, and went back to 21.08? Tried to print a replacement ABS part and the extruder cooled to 200C on the second layer and on the 3/4 layer turned off the heat bed. Needless to say a few layers later the print popped off the bed. :lol:
I will express my CRAZY ideas at any time! So you have been warned. None of my opinions are Lulzbots and can be wrong at any second.

Hmm, I'm liking this in general, especially having access to the "Horizontal Expansion" feature. Maybe I can finally print parts that fit together.

Unfortunately, I'm not actually getting successful prints. Having trouble catching exactly what's going on, but it gets up to a certain height, seems like around 5-7mm, and the part pops off the bed and starts being dragged around. This is the HIPS Standard profile. I think I've tried about 6 times and 5/6 were the same failure. I even turned on a huge brim to no avail.

I think maybe it's lack of initial layer line width.
What bed temperature does it maintain throughout the print? Open the file in a text editor and search for M140 and M190. Do they all match?
That doesn't seem to be it. The temperature stayed consistent while printing...

pi@octopi:~/.octoprint/uploads $ grep 'M1[49]0' LM_Auger.gcode
M140 S85 ; start bed heating up
M190 S85 ; wait for bed to reach printing temp
M140 S85
M140 S50 ; start bed cooling
M190 R50 ; wait for bed to cool down to removal temp
M140 S50; keep temperature or cool down

Although wait a minute.. 85? It's 110 in the old version of Cura. This may be a raging clue.

Not only that, but the print temperature is 200 instead of 240. That seems way too low for HIPS and doesn't seem healthy. I'm going to try with proper temperatures and see what happens.

So when I set the "build plate temperature" to 110, the part no longer pops off, which is great. The print temperature was tricky: apparently there's a default value for "Flow Temperature Graph" of "[[3.5,200],[7.0,240]]", which overrides the other temperature settings. I can't find any real documentation for this, and it's not clear that Lulzbot intends for this setting to take effect, so instead I just deleted the value and it seems to go back to using the statically configured temperatures. I'm out of time for today but I'll use this for my next print.

I tried to use the beta but I get no material selection nor can I create a new material. I searched the forum and I don't see this issue mentioned, so I'm thinking I'm just not doing something right.

In the drop-down box bambooFill(colorFabb) is listed but cannot be changed.

Using beta 2.6.45
Windows 10 64 bit

Any help would be appreciated.

Thanks,
Steve

Version number on the windows desktop icon doesnt change when you upgrade to new versions.

Hello,

What are the plans to compile this for 64bit?

In version 2.6.43 it´s not possible to create or duplicate a material, nothing happens.
Dual extrussion is useless until we can manage materials with specific configuration (temperature, density, etc).

EDIT: I found a temporary fix to create materials. You must export an existing one, make a copy of that .XML file, edit it with different values (also change the GUID parameter to random values with same string format). Then, if you import the material it will appear on the list and you can use it.

material_bed_temperature is still set to 85 in quality/lulzbot_mini/HIPS_(Village_Plastics)_*.cfg in 2.6.43. I'm still overriding this setting to 110 in order to prevent failed prints, as well as removing the "Flow Temperature Graph" setting. I think Lulzbot have moved away from HIPS, but it's still the material of choice for our makerspace so it would be great to see this profile work correctly out of the box.
