Hi PeterF The printer has 3 main types of board and an LCD display/sdcard interface. The Arduino card I got from http://www.ebay.co.uk/itm/171827024551 for £7-99 (you could possibly do better on this). This then has a Ramps 1.4 card which I got from http://www.ebay.co.uk/itm/151768808587 for £3.78. The Ramps 4 card has 5 plug in Stepper drivers which I got from http://www.ebay.co.uk/itm/141672347924 @ £1.32 each (I ordered 6). It also has the thermistor inputs and the head/bed heater control outputs. The Arduino board is also attached to the graphic display and SD card adapter which I got from http://www.ebay.co.uk/itm/141679594646 for £6.48. I also ordered some thermistors and optical end stops for a few pounds. So far I don't think I have spent much for what I have ordered. Time will tell when it eventually arrives. Am more concerned about drilling the granite countertop than the electronics. Best Regards picclock |

It's amazing what you can buy for remarkably little money in the way of pre-assembled electronics these days. At those prices you couldn't buy the components ! |

Hi picclock, Some very nice links there, thanks a lot. Have to investigate a bit closer but I don't think I can get so much better deals than those. When it comes to drill the granite. I had to get rid of a very slightly broken corner on one of the benchtop granite "boards" in our kitchen. What worked the best was my diamond file with which a gentle hand quickly fixed the problems. That said, I guess that diamond-coated drill bits might be a good way forward. As an example of types and prices, the link below lists some easily available ones at reasonable cost. http://www.arceurotrade.co.uk/Catalogue/Diamond-Tools/Diamond-Drills Slow going (light pressure) and maybe water cooling should do the trick.

Hi PeterE I have ordered a couple of 6mm diamond drills from flea bay. I figure I will have to drill about a dozen or so holes hence the spare. I plan to do the drilling on my mill so that all is controllable with minimal lateral forces. Its just something I've never done before - hence the trepidation. I will make aluminium holders for the y rails and do away with the studding altogether. The gantry will be mounted with side plated directly to the granite so the relationship between the two will be v good. I have ordered up a cheapy set of ABS printed plastic parts for $20 (around £13), so that will be enough to get me started to print the final pieces for the machine. Am also getting on well with designspark - done cones now :med:. Will have to cheat on text though and import it from sketchup when needed. Looking forward to when all the parts arrive and I can do a build. Will start a thread with piccys in Project logs, though there are a lot of build threads for this type of machine on the internet, so I'm not sure how useful it will be. Best Regards picclock |

Hi picclock, Will be interesting to hear/read about the granite drilling exercise when time comes. Your thoughts and mental sketches for the "frame" sound very ridgid and it will be interesting to see the build. One thing that occurred to me today was that the four printed corner pieces making up the Y axis have no means to secure them to a bed surface. No "ears" or any other means to fit a screw. Think I am going to make some add-on ears from a couple of alu bits. Just haven't worked out the final solution yet. But that should give even more rigidity and stability to the whole setup.
