  1. With UltiGCode the heating is done in the firmware, not in the GCode, so no luck there. I don't have an UM2, so could not test that.
  2. I know (I also can do that in Repetier Host) but OTOH sometimes I do have the object already sliced and just want to print it. Don't know if it's worth the discussion, the plugin helps me and I just wanted to share if someone is similar impatient ;-).
  3. This is especially for the impatient My nozzle usually takes appr. 2 minutes to heat up for ABS, think of a small print with about 5 min printtime. This saves you almost 25% of printing time (in fact the time the nozzle needs to heat up). Most important in your post are the words "and then" it heats the nozzle, this is done in parallel with the plugin.
  4. When printing small parts I got a bit embarrased because Cura G-Code first heats the bed, waits for it to reach its temperature, then the nozzle. So I decided to code a small Cura 15.04-plugin to start heating the nozzle while in parallel heating the bed. The code: #Name: Parallel Heat#Info: Start pre-heating the nozzle while heating the bed#Depend: GCode#Type: postprocess#Param: temperature(float:170) Preheat Temperature (deg C)__copyright__ = "Copyright © 2016 Roland Steinbach - Released under terms of the AGPLv3 License"import refrom Cura.util import profilewith open(filename, "r") as f:lines = f.readlines()with open(filename, "w") as f:f.write("M104 S%f\n" % (temperature))for lIndex in xrange(len(lines)):line = lines[lIndex]f.write(line) Save this as "parallelHeat.py" and place it in your plugin-folder. Then activate it and set a somewhat reasonable temperature for the nozzle. Now when starting to print, the nozzle gets heated in parallel with the bed. This speeds up the print appr. your bed-heat time.
