2. ## repead a print true doodle3d nozzle does not heatup again.

When printing true doodle3d and a second print is started the nozzle stays cold. This can be a Doodle3D Problem. I have a UM0, two heads, heated bed, ultimaker controller. Cura 15.02.1 and a Doodle3d box. Cura detects the Doodle3D box. After slicing I hit the top middle button it says print with Doodle3D. After a popup window saying: Printer found waiting for print command. Temperature: 23 Bed: 19 And a print button. After hitting the button I see the bet is going to 70 C Nozzle still 23 The gcode is send to the Doodle3D box and the heated bed starts to rise in temperature. The
3. ## Heated bed temperature

I was planning to make a step by step list with what to do to solve his problem, but if he is not responding than it has no use.
4. ## Heated bed temperature

Yes you are right. For the OP. What colour code is the resistor?

6. ## Heated bed temperature

Ok a little it of theory. The schematic. +5 | - | | | | R pullup | | - | + ---- Messure | - | | \ Th R thermistor | | - | Gnd The value of a thermistor is usualy messures at 25 degree celsius. In youre case 100 K. Just messure it with a good multimeter. Wat would you messure in the above schematig? I = U / (Rp + Rth) Um = I * RTh Um = Rth * U / Rp+Rth) Um = 100000 * 5 / 100000 + 4700 This is about 4.77 volt. What happens wen the termistor heats up? The resistans drops. Then te voltage on M drops too. When the thermistor is 4k7 ohm, the voltage is 2.5 volt. 4.7 K
7. ## Cura wishlist

I have two wishes yet. 1 - When preheating make an option to preheat the nozzel and the bed together, or dont go to the info screen after a selection. prehead bed and nozzel 1 prehead bed and nozzel 2 prehead bed and nozzel 1 and 2 2 - When i switch from quick print to full settings mode the setings are allways reset to PLA defaults. Keep the settings for ABS if selected in quickprint mode. Or better, make private defaults, so i can select for instance Yellow ABS and te right settings are taken. keep up the good work, pim.
