Ditto+ Probelm

We have a problem. The ditto+ is reading a heat of around 354 C which means that the printer will not heat up because it thinks that to get the the appropriate temperature it needs to cool down. So when we tell it to print something will will just sit there and try to cool down to temperature it cannot cool down to because its temperature is not higher than the temperature we want it at. We think that the issue is with the thermistor because we have checked the wiring for loose connections. If you have any ideas about how to fix this it would be appreciated.

Build Session 4


We have begun sawdering the wires to the sensors, built the belt holder, put the top bracket on, and attached the three arms. We have also begun assembling the extruder. Also, we have begun attaching the wires to the board.




Build Session 3

Put the three vertical beam on, mounted the sensor and assembled the top bracket.


Note: Used m3 10mm for ball joints of arm



-Attached the three vertical beams

-Mounted the sensor

-Assembled the top bracket




-The video told us to mount the sensor on one way but the google groups suggested mounting it on the other way so we did.

Build Session 2

Finishing the assembly of the 3rd corner of the base. We also added the motors to the corner base pieces.




-Completed base







-Mounted power supply unit


Power Supply







-Mounted Arduino








-On the last bar of the base it was a bit difficult to line up the nuts. We found that it helped to have two people and have each person do one side at the same time.

Build Session 1

So far we have unboxed the entire printer, have taken pictures and logged all the bags inside the boxes that have been shipped. We have also begun the construction of the printer itself.

Since we have just begun this construction of this printer, we are not sure on how tight the screws should be. If we do happen to over tighten a screw into the acrylic, it would crack the material which would not be good.

– Unsure of how tight the screws on the pieces should be
