Wanhao Duplicator 3

[Mjolinor]

I am not entirely sure but I think the Wanhao and the Flashforge Creator are essentially the same printer. I bought a Duplicator 3 cheap off ebay and decided it needed to make better prints. I also have a Stratasys and wanted to get somewhere near that.

I blocked all the holes up with polycarbonate and installed a fan to blow air through the filament holder tube. I then made a heater in a pipe that fits the back of the printer, joining the tubes together and ran it from the 24 volt PSU underneath. The heater is about 25 watts and is just on. There is no extra input for a thermistor on the control board though there is an output available. If I could get the software sources I could control it but I set it low enough to be on all the time so it is not really important. It takes a while to warm up but makes a huger difference to the prints.

I also wrote a small C programme that adds this:

G91
G1 Z10
G90
G1 Y50
G4 P15000

between every second layer to allow the ABS to cool down.
