PP3DP UP! mini Extruder Temperature Modification
Description
This Modification Allows The Setting Of The Extruder Temperature Of The Pp3Dp Up! Mini Between 197°C And 275° In Steps Of Approx. 1.3°C. Other Ranges And Other Steps Are Possible By Using Different Resistors/Resistor Stages. Puts A Cap On To The Extruder Top. Should Fit Other Printers Like The Pp3Dp Up! Plus, Afinia And Similar, As Well. The Extruder Temperature Is Measured By A Pt100 Element. In The Relevant Temperature Range The Resistance Of The Pt100 Increases By Approx. 3.65 Ohm Every 10°C. If We Put A Resistor With 3.65 Ohm In Line With The Pt100, The Temperature Controller "Things" That The Temperature Of The Extruder Is 10°C Higher Than It Really Is. So It Tries To Control A Temperature Of 275°C, But In Controls Only 265°C. For Instance. By Applying Different Resistances We Can Trick The Controller To Control Different Temperatures. Attention: The Controller Always Tries To Control 275°C (For Abs; ~225°C For Pla; 266°C Afinia, ...) And Shows This Temperature On Screen, Even Though It Is Tricked To Control A Lower Temperature. Thanks To All The Distributors For All The Helpful Information On Internet.
