  1. I have question about g code. I am excited to push my ultimaker to the limit! and to do so want to understand the gcode as much as possible. I use grasshopper and rhino to design parametric objects and in the past have run a cnc mil directly from gcode generated by grasshopper. GH is a visual scripting program for rhino a popular 3d modeling tool. anyway there is a plugin for gh called silkworm designed to generate gcode for 3d printing directly from gh so that a s a model changes the gcode updates. Interesting stuff. Here is the link; http://projectsilkworm.com/ .

    So I have some setting s I need to feed into this plug in to get in to sync with the ultimaker. can you advise?

    These are some default values from another gcoder. Can anyone confirm whether they apply to the ultimaker and correct them where they may differ? Thanks -

    If you can confirm or correct this list please make it clear which value you have confirmed or corrected Thanks!

  2. When the print is at the center of the build plate , there is some deflection so that the table moves slightly up and down, affecting the quality of the print. As the table is only supported from the back the only thing i can imagine is to keep models as close as possible the the back and slow down....I forget what speed this was happening at... Ill keep better notes in the future , now I am printing at 50... and infill at 70-100 or so,

  3. I also get a lot of wobbling on the table towards the top 3/4 of the build volume...I have been placing the prints as clise to the back as possible but this limits my size... It would be a nice feature if the machine would slowly ramp down the speed as the height increases to avoid a clear print line from a change in settings... also i wish this feature were dynamic for overhangs so that the code slowed if the overhang increases and ramps back up as the overhang lessens. Really it needs optimization. these prints take forever

  4. Hey forum, i just downloaded the updated cura and this stop at height tweak at height ruined my first print on the new software. how do i disable it? how do i use it? whats it for? my machine retracted the filament so far that it started printing without having filament anywhere close to the nozzle.... any advice is appreciated thanks.
