RobRob Posted December 30, 2015 Share Posted December 30, 2015 Gina, what dimensions ring did you put between the camera and the lens (I noticed a little purple ring between the two in your setup)... Link to comment Share on other sites More sharing options...
Gina Posted December 30, 2015 Author Share Posted December 30, 2015 The lens screws straight onto the camera. Link to comment Share on other sites More sharing options...

Gina Posted December 31, 2015 Author Share Posted December 31, 2015 Looking good Rob I see you got the printer working pretty quickly, how do you like it? Link to comment Share on other sites More sharing options...
RobRob Posted December 31, 2015 Share Posted December 31, 2015 Well, so far it is holding up pretty good. software to print is called Cura (version 17.10) and it is quite intuitive. I don't like the way it builds up support structures though. When you remove them it leave an rippled structure behind which you need to take off with hand tools.Sometimes when printing starts it does not provide material right at the start. luckily it starts with an brim around the printed object which has no function so if this partly doesn't print due to the lack of material it does not really mind...So far I printed with ABS 3mm black only and a small bit (1m) of yellow HIPS which was included with the printer. Both work well although I think the HIPS prints a bit better. I should also be able to print PLA (ABS is officially not supported but prints ok so far).

Gina Posted December 31, 2015 Author Share Posted December 31, 2015 It takes a while for filament to start coming out of the nozzle. I think this is one purpose of the brim - it happens with all my printers. I noticed in the reviews that your printer prints HIPS, it's a type of filament I haven't tried and I think I will. I'll buy some next week and see how I get on with it. My RepRap style printers are designed to take any filament with extrusion temperature up to 300°C. My best results so far have been with ABS but I've also tried PLA and Nylon with some success. Link to comment Share on other sites More sharing options...
RobRob Posted January 1, 2016 Share Posted January 1, 2016 Hi Gina, first of all a Happy New Year. Another question: what internal temperature sensor did you use (I notice for outside temperature you used the DHT22 but I couldn't find the type nr. of the internal sensor)?

RobRob Posted January 1, 2016 Share Posted January 1, 2016 I made a small addition to your design. I've added a ring at the top of the camera to ensure the focus and aperture gears keep pressed down:http://www.musquetier.nl/downloads/Upper_Ring.skpAlso did my first design of the housing (will be printed white): Link to comment Share on other sites More sharing options...
RobRob Posted January 1, 2016 Share Posted January 1, 2016 Printing for 9 hours en 4 minutes the needed 479 layers with lots of redundant support structure (here 3/5 of a single layer):https://youtu.be/PtWgUEo-4ow Link to comment Share on other sites More sharing options...
Gina Posted January 1, 2016 Author Share Posted January 1, 2016 Thats a long time. I use Repetier Host with Slic3r for my software. I have Cura but didn't like the look of it. Link to comment Share on other sites More sharing options...
RobRob Posted January 2, 2016 Share Posted January 2, 2016 But it is worth it: test fit: Support structure broke loose realy easy this time leaving hardly any traces. I used 0.2 mm as Z gap which I suspect helped a lot to ensure it does not stick so much. Link to comment Share on other sites More sharing options...
RobRob Posted January 2, 2016 Share Posted January 2, 2016 Gina: would it be ok if I use some of your code? Particular for controlling the stepper motor and the DHT22? Link to comment Share on other sites More sharing options...
Gina Posted January 2, 2016 Author Share Posted January 2, 2016 Looks good Rob My software wouldn't have used support for that angle but if you're happy with it that's fine Hint for the top - I found I needed black to stop light from the Arduino Nano getting to the dome. Since I had printed the case in light green I used "direct onto plastic" matt black spray paint (stuck well to ABS - don't know about other plastics).Yes, I'm very happy for you to use my code In fact, I publish the code for all my projects for others to use as they feel fit. All my projects are put in the Public Domain for general interest and for anyone to use if they like. As usual I give no guarantees that anything I publish/post will work nor may I be liable for any damage or distress caused by building them.

Gina Posted January 2, 2016 Author Share Posted January 2, 2016 Should be in this thread or in previous thread this thread links to but I'll check. Be a bit later because I'm only on a short break while sorting out urgent storm and rain repairs. Dry weaather ATM but only briefly. Link to comment Share on other sites More sharing options...

ChrisLX200 Posted January 3, 2016 Share Posted January 3, 2016 I'm also in the process of making a few more AllSky cams ;-) The printed casing should work well because the hollow walls/air pockets will provide better insulation and keep the heat inside so it doesn't mist up so easily. The camera plate will be alloy though (which acts as a heat sink). My domes still have the protective coverings in place but I'll use the same flange and rubber seal arrangement as last time which worked very well to keep water out.ChrisH Link to comment Share on other sites More sharing options...
