-    * +    * --> **Yes, A room temperature of ''±20°C'' makes plasticine print. It under extrudes when colder.** 
 +  * Slower speed helps (no tearing), but lines are a little crumbly at ''1.5w, 0.5z, 5f 0pct''? 
 +  * Material Flow Rate Multiplier (in the Head-control section). Adjustments are sent to print head when pressing enter, or when clicking outside the number box (setting the cursor in another number box). This setting is thus live and overrides the Slic3r material flow parameter. 
 +  * Head Control - Nozzle size overrides the nozzle size set in Slic3r.

 +Aha-moment: Extrusion width seems to only define line to line distance. It doesn't change the flow rate. 
 +  * {{:hyrel:2020_10_08_plasticine_first_layer_width_3mm_web.jpg?400|}}\\ 1st layer extrusion width of 3mm: good bed adhesion, perfect lines (''Formlab plasticine defaule 10'').

 +  * --> So maybe the room and material temperature are more important than flowrate.

   * Do a visual test (video recording?) with lines on paper to see if the printer really moves 8mm/s. I have a feeling the printer moves faster than the first successful print.   * Do a visual test (video recording?) with lines on paper to see if the printer really moves 8mm/s.

 +==== Issues ==== 
 +  * Printer sometimes doesn't wait until desired temperature is reached. 
 +  * After stopping the print (Kill function), **reset Z-zero** 
 +  * It seems that Repetrel doesn't do accelerations? Why is that? 
 + 
 + 
 + 
 +==== Random knowledge ==== 
 +  * ''M756'': S[layer thickness in mm] - for flow calculation 
 +  * ''M221'': sets flow rate 
 +  * ''M104'': print temperature 
 +  * Davo 01/10/2015 
 +    * **Reset**: will reboot the 407 motion controller 
 +    * **Aux**: will toggle a relay, which can be used to allow or deny power to an auxiliary item like an air filter or heater 
 +    * **Respond**: was intended to be used to resume after a pause, but I don't know if it's enabled yet 
 +  * If you hear tics in a regular or random pattern, chances are you're printing with 'Spiral mode' selected. The tics are generated by the the Z-axis motor.
