Netfabb upgrade 4.93 what´s new?

[greengecko 8]

Hi there seems to be a new upgrade in netfabb 4.93. Does anyone have an idea whats new. Does retraction work now?

Currently I am only using it for repairing models, but maybe it is useable again?

I just checked the update and went for the material settings, and the pullback is still defined in RPM, which leads me to believe that it's probably still not working, but I haven't checked it yet.

the change log isn't updated yet: http://wiki.netfabb.com/Version

I just tested the retraction pyramid and also set in the expert settings some parameters in the jump section, but I could not see any retraction, so it seems also to me, it is still not working. Too bad I liked the ease of netfabb. Also the slicer does a nice way to when printing surfaces.

The ":" in the comments is now deleted in the gcode so a direkt print via printrun should work. It worked via the ulticontroller.

So let´s wait and see until the change log is updated

what values did you try for retraction? 400 is the default, afaik, and the max is 999?

I tried the values from my pervious trials

Jump speed 180 mm/s

Z-jump speed 20 mm/s

Pull-back speed 150 RPM

not sure where I had these values from.

I had some values in retraction that seem to work fine as far as speed (I don't know what they were off the top of my head) however, my issue with retraction was that it appeared to always go the wrong direction. Before a move it would PUSH on causing a huge blob and back-pressure that caused a plug half the time... then it would move with WORSE stringing, and then pull off after the move which results in not enough extrusion immediately after the move.

I'm very happy with NetFabb right now with no retraction at all... but it sure would be nice if it had working retraction.

I haven't used netfabb in ages, including the latest version, but did you try entering a negative pull-back speed?

[codemaven 0]

Yes I tried that. Unfortunately it doesn't accept negative values...

Just trying the new firmware now... One welcome change is that after saving the GCode to a file it has a popup message indicating when it is finished... It used to hang while writing and then come back with no indication... also it seems to write faster...

Netfabb 4.9.3 upgrade seems to be mostly Fabbster driven:
