ins3DRostockpronsole.txt - May 24, 2019 version This is the full detailed instructions for using the Rostock with pronsole (the old way). Many of the steps (i.e., R.1-R.7) can usually be skipped; see ins3DRostockpronsolequick.txt for minimal instructions.

      • NOTE*** The Rostock is currently miscalibrated & prints too small in the x & y directions. These instructions change the scale to compensate. For better results, multiply all x & y values by 1.065 when designing the object & use 1 instead of 1.065 at R.37-R.38 or just skip R.32-R.39.

ins3DRostockend.txt - June 13, 2019 version To remove printed objects from the bed: Z.1 Spread water around the base of the object so a shallow layer touches it all around Z.2 Wait until the object has cooled fully and water has soaked in; add more water as needed to maintain a shallow layer all around Z.3 If the object is sturdy you can try to remove it by slowly but firmly trying to tilt it in different directions; if it comes off skip Z.4-Z.8 Z.4 Remove tape around base of object Z.5 Slice under the object from various directions with a razor blade (careful!) Z.6 Pry up the object from different directions with a putty knife or similar item; if the object comes off skip Z.7-Z.8 Z.7 Wait some more; add more water as needed to maintain a shallow layer all around Z.8 Repeat steps Z.5-Z.8 Z.9 Dry off the bed

ins3DRostockprob.txt - June 13, 2019 version To pause printing if using pronsole: P.1 pause (it may take a while to stop) P.2 If you might want to resume the print avoid moving the printhead unless necessary and only use the move commands to move it (i.e., move z 10) being careful not to hit the partial print with the printhead unit & noting how much it is moved in each direction P.3 To resume printing: If the printhead has not been moved skip P.4 P.4 Use move commands to move the printhead back to where it paused (i.e., move z -10) being careful not to hit the partial print with the printhead unit P.5 resume

If you can't fix a problem & expert help is not available: !.1 If the Rostock power has already been turned off STOP here !.2 pause !.3 Press knob on Rostock (to right of display on base) !.4 Select Adjust Temps by turning knob !.5 Press knob !.6 Select NOZ Temp: by turning knob !.7 Press knob !.8 Set temperature to 0 by turning knob !.9 Press knob !.10 Get expert help when it becomes available; it may be possible to resume printing
