Printer display for da vinci mini w
http://soliforum.com/i/?bnCqC7d.jpg

In case I have to run long prints, I wanted to see the printer status without running the PC. Since there was no mobile app from the manufacturer, which provides this function, I have a Raspberry Pi used. The program is written in processing and typed very roughly and quickly together. It shuts off as soon as the runtime drops below one minute. one could add further functions, e.g. the filament change or similar, which I did not implement. So you can improve or tinker with the program. A feedback about this would be interesting, thanks.

A known mistake. The USB switch always selects the device that was last turned on. So if you boot the PC up again while the connection to the Raspberry exists, the program will hang because the communication was severely interrupted. I have not installed error handling so far.

I'm using a Pi2B and a Wi-Fi stick so I can display the information with vnc on other devices.

Very nice! Thanks for sharing.

Im also interested in your advanced cooling system. Could you share the files too?

Very nice work!

A side question, where are you pulling power for the fan? I looked over your pictures but did not see the connection (maybe I did not look carefully enough).

Looks to me it's on the little PCB to keep the wiring stock.

Printing since 2009 and still love it!

The power cables of the fan run along the bowden extruder. I connected the cables to the PTFE tube with a shrink tube.

There is no additional board for the fan installed. The wires go out in front of the extruder and are connected to a 12 V power supply.

I should maybe create an extra post to the object cooler ;-)

Re: Printer display and object cooler for da vinci mini w

First, thanks for sharing this.
I have 2 questions: Is it display only or is it a touch screen with controls?
Does the location of the parts fan limit the available print area?

Re: Printer display and object cooler for da vinci mini w

Hi osmosis
the software i uploaded is a display only version. It is what I needed at this time. But the program is written in processing (processing.org) and you can attach own functions. sorry, the programm is a quick and dirty version ;-)

The parts for the object fan does not limit the print area! However, you must remove a rib in the printer cover. Otherwise, the fan will strike there and block the Z axis. At Thingiverse I uploaded detailed photos.
