    I use E3D's version, they call edge http://e3d-online.com/Edge Yes it is expensive, especially as the reels are smaller, but as you say, you get what you pay for...
  2. Dr_Ju_ju
    Try PetG, it has the strength of ABS but prints easily @ 80 bed with 240 hot end....
  3. Dr_Ju_ju
    Just check that the cartridge will actually fit the hot-end, I've had some where the diameter was greater than the hole...
  4. Dr_Ju_ju
    While at it, don't forget to make provision for a Pi3, hubs, cables etc....
  5. Dr_Ju_ju
    Brilliant !!

    I'm in the process of putting one of these together & I've found that the 'stock' 4 wheel Y & Z printed carriages, wouldn't allow correct alignment correct running etc. So I've tried the 2, 3-wheeled versions http://www.thingiverse.com/thing:1802733 & http://www.thingiverse.com/thing:1930200 (V2) & these work a treat.... Also a good source of some info is MavericCCIE's build on Openbuilds http://www.openbuilds.com/builds/d-bot-with-mods.4685/

    have a look @ BeltingOnline, the 2.5mm, 177.5 mm, should be right one http://www.beltingonline.com/t2-5-synchroflex-timing-belts-2903

    I've used it to cut 3mm acrylic & copper pcb's, not tried anything else yet, I use it in a well ventilated room, but not in a fume cabinet.

    I think another Gina project coming on.... I bought one of these http://www.ebay.co.uk/itm/445nm-2-5W-2500mW-Blue-Laser-Module-With-Heatsink-For-DIY-Laser-Cutter-Engraver-/322497845897?hash=item4b165e9a89 then together with a Mostly Printed CNC machine (https://www.vicious1.com/assembly/ & http://www.thingiverse.com/thing:790533) but obviously any machine that can move X & Y (Z movement to achieve fine focus), can be used. Control of the laser is done with the 'hot-end cooling fan' control, 10% to switch it on & 100% to cut...
  10. Dr_Ju_ju
    Another thought..... Add a Laser cutter to your big printer, then you can cut acrylic sheet, which could then be formed into a dome with welded edges....
  11. Dr_Ju_ju
    One thought to reduce some of the hard work, would be to use a pre-formed dome e.g. http://www.ebay.co.uk/itm/Perspex-Acrylic-Dome-700mm-dia-/332184848462?hash=item4d57c2884e:g:NyYAAOSwx-9W1bt6 which could then be cut\modified\painted etc...

    Good luck !! My 2$ - one thing I've found with the bigger platforms is the limitations of the Ramps\Arduino controllers. I've used Smoothie Ware v2 board http://smoothieware.org/smoothieboard, yes its more expensive but gives better control.

    You could also try AstroBoot http://www.astroboot.co.uk/AstroBoot

    Canon's usually run on 8.4 volts (all mine do) & I run them off a buck converter e.g. http://www.ebay.co.uk/itm/1-3-5-x-LM2596-DC-DC-Buck-Converter-Adjustable-Power-Supply-Step-Down-Module-UK-/161818793869?var=&hash=item25ad26d78d:m:mfnqbLbvaO6JOj7AXxfgPMQ with no issues..
  15. Dr_Ju_ju
    for the 9v supply, get a bucky converter http://www.ebay.co.uk/itm/LM2596-DC-DC-Switching-Adjustable-Step-Down-Voltage-Regulator-Converter-3V-40V-/172058668488?var=&hash=item280f7eedc8:m:mDHLwFGVrh49Tb7BA-Y6CWg & run it from your 12v supply
  16. Dr_Ju_ju
    Good Luck, if you have any problems (especially if you aren't used to programming Arduino's) just shout....
  17. Dr_Ju_ju
    As stated elsewhere the most expensive part is the stepper, I use these http://www.ebay.co.uk/itm/27-1-Planetary-Gearbox-Nema-17-Stepper-Motor-1-68A-DIY-CNC-Robot-3D-Printer-/121683241474?hash=item1c54e2ea02, for approx £35, together with boxes\components\mounting parts etc. the complete package can be done for £50-£60.....
  18. Dr_Ju_ju
    The Arduino on its own cannot drive anyform of motor, that's why the 'Arduino' part is usually made up from an Arduino Nano plus a motor driver module e.g. DRV8825, and some other components e.g. power connector etc... I mount mine in a custom 'black box' and can move it between various OTA's\Motors, so to answer your question, build the right one and you can re-deploy as required..
  19. Dr_Ju_ju
    Hi Steve, The mount doesn't need to be perfectly level, just get it close, & then ensure that your polar alignment is good....
  20. Dr_Ju_ju
    The link doesn't work, but from the bay, something like this: http://www.ebay.co.uk/itm/NEW-Startech-Com-7-Port-Black-Usb-2-0-Hub-ST7202USBGB-/401171601806?hash=item5d67b0d98e:g:OpgAAOSw-itXslLC
  21. Dr_Ju_ju
    Try something like this instead https://www.amazon.co.uk/gp/product/B00LH5ZPNY/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 yes it's more expensive, but you'll still have your hair, instead of being pulled out, trying to make things work.....
  22. Dr_Ju_ju
    I hope you mean that you'll use a powered USB hub, as 'y-splitting' the one lead. won't work.....
  23. Dr_Ju_ju
    Welcome Back, wishing you clear skies..
  24. Dr_Ju_ju
    just for info, INDI, is the Linux version of EqMod.. There's another thread running under software, that goes into more detail, i.e.

    Gina, To divert any run-off water, dig a French drain along the top edge of the path with fingers down to the fence. This is just a 200x200 mm trench filled with pea gravel for the water to seep into...
