Hey everyone, I'm the designer of this "little" hack, and the .ini file is designed to stop the extruder motor from moving, to turn the temperature sensor to zero, and to change the the layer height settings. It also changes the start.plugin and should be backed up prior. I designed this hack for an UMO with a standard size bed, so only the plotter arm and the .ini file were needed. As it was pointed out earlier, it would be good to create a duplicate machine that uses the .ini profile. The gcode slicer visualisation in Cura won't show an accurate representation of what the printer will print when it comes to pen plotting. I have a custom metal bed on my UMO, and with proper pen height calibration (about 0.6mm below the nozzle) the pen arm will bend to accommodate the pressure of the pen on the lower levels without scratching and will still keep contact at higher levels.
