Cura2 LulzBot Edition Beta Testers Needed!

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

During dual extrusion, at the last switch from front extruder to back, the nozzle bed makes an unexpected move.

During this last switch the extruders seem to go to X0,Y250 or something like that to "wipe" on an imaginary prime tower.
They then go back to the correct prime tower and the print continues and finishes OK.

Sorry, the post directly above should say the nozzles move unexpectedly to X0Y0. What I mean is the initial probing point/corner.

Any plans for an Appimage or Flatpak package? This would be an easy way to provide cross-disto support on Linux distributions.

When typing in a negative number for the model MOVE, the "-" does not show in the display.

Example: I wanted to sink the model into the build plate before slicing, I entered "-10" for "Z" on the Move. The negative sign did not show, but the model did move into the build plate.

It seems like the cooling fan speed is sent every time the extruders switch when dual extruding. This makes it a challenge to use the manual controls of the TAZ 6 to change fan speeds at a challenging part of a print. Once one extruder is done being used, the fan speed is left alone--no more extruder switching.

Is it necessary to resend fan speed commands when the extruders switch?

When using dual extrusion extruder #1 stays at the holding temp even when it is no longer needed for the rest of the print(used for support). Extruder #2, when used as support, goes to 0 degrees when it is no longer needed.

I think extruder #1 should act like extruder #2.

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.

We've released a new version: Cura 2 LulzBot Edition Beta 2.6.38.

Among the many improvements, Mac OS X users should have improved USB connection stability.

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?

In dual extrusion, the software seems to have forgotten to compensate for the extruder offset. I had been printing successfully till this point in this regard. The offset was checked and is identical to the extruder offset in the picture. Disturbing that changing anything in the print profile would have this effect.

Eventually I had to delete all profiles and removed software and re-installed. Now printing this part successfully using the "Standard" profile as a basis again.
