thanks Eric for the link I also found this what do you think ?? http://cgi.ebay.com.au/DRO-DIGITAL-READOUT-DISPLAY-2-AXIS-WITH-5-8-SCALES_W0QQitemZ260401141779QQcmdZViewItemQQptZAU_BnI_Woodworking_Metalworking?hash=item260401141779&_trksid=p3286.c0.m14&_trkparms=66%3A2|65%3A1|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50 |

I see you are discussing DRO scales a little. If you want to make them a permanent thing, totally forget the linear scales you are looking at. I have been down that road for a few years now, and a few other people I know have been there as well. For something that you want to last a year or so, then fine, but any longer than that, they can become a nightmare. Just when you are half way thru a critical bit of machining and the damned things go wrong. A tiny bit of swarf, or any mention of fluids, plus the electrical joints and batteries are another weak point, will just cause them to pop their clogs. Don't get me wrong, for a total beginner or someone who has got no cash to spare at all, it can be a way to go, but for long term operations you should be saving your hard earned pennies a little longer and go for a proper glass scale version, rather than going for this cheaper scale system and having to replace them a little down the line. I still used one on my mill, for reading the quill, but that is only because I know that it will be safe up on the head away from the muck and grime, plus no cable movement at all. All other places on a mill and you are asking for trouble in the long run. John |

So the controller board kit, timing gears and belts showed up yesterday. I am going to get some pictures of it all soon and do a step by step of the assembly of the controller. On another front, I got a benefactor for this conversion... A friend who has a vested interest of getting some parts made, has made a loan to get some more things for the build :headbang: Hopefully tomorrow, I will build the controller. Eric |

Well, I spent most of Saturday cleaning and organizing the shop. I am still not anywhere near done that but who is? I got a little time on Sunday to start building the CNC controller: Here is the board and most of the parts. Ignore the blurries... cell phone camera! Added a few resistors: Then some caps: OFC, this was done at my mother in-laws. I forgot my multimeter at home and didn't want to continue until I had tested the stuff I had already done. Ordering some more stuff today or tomorrow! Eric |
