| I was remembering today that when Z would do a rapid move you would hear a contacter go "clunk"...then off she would go...so maybe that was what was going on there ?? They really never gutted our machines so I didnt get to see how the bits worked Bill  |

| Still working on it when I can.. I have the pluto and now a mesa board which will probably be what actually runs the k&t. I got a great deal on one. 72 i/o with lots of configureablity. http://www.mesanet.com/motioncardinfo.html anyways - I have a 6kva 3 phase transformer that I will be using for the power supply.. Need to make a bridge and such. should be playing with the pluto the next few day. sam |

| I hooked a 1024 line encoder to the pluto and spun it in the drill press at 6500rpm.. Kept position perfectly. I didn't go any faster as it was a bit scary at that.  (I will probably only max out at 1500rpm at the most)that is 443733 edges per second.. Cool. sam |

| I must say, this is hardcore! Did you notify the EMC-guys about your conversion? I know people running EMC on production machines but in "silence to the public". And when people put a lot of spare time to EMC they should be credited at least with an e-mail. Keep up with the good work, this is really a nice project!  Regards, Sven |

| I consider the emc2 developer group 'friends' - At least they put up with my stupid questions. I have met most of them at the http://www.cnc-workshop.com/ last year. Nice bunch and very very smart. I have not had time to work on anything with the move.. But as things die down here I hope to jump back into it. I need to mill a bunch more circuit boards - at least 3 more. (have to build a garage this summer also..) sam |

| Hey Sam great thread, I am going down the same path as you, I was wondering if you had played around with the pluto and the mesa card ? I am trying to work out which will suit my needs better, I was thinking of using the pluto on my first router (650mm by 600mm by 100mm xyz) and the mesa for my next build which will be much larger, simply for the extra IO. I have read the docs and understand there are HAL drivers already for both but am not able to do any real world testing yet. I am going to use L298's to drive my small router servo's, should make for simple testing, might look around and see if there are any generic board layout's around. Cheers. Russell. |

| All I have done so far is test the plutos encoder counting abillity. Which seems really good. The mesa I have not even taken out of the static bag One of the developers just got his Sherline lathe setup with the pluto using the pluto and l298's. He has threading working and everything. http://timeguy.com/cradek/cnc/lathe there isn't enough time in the day.. I did setup a microswitch on our gantry to set tool lengths. Now I can mill circuit boards a lot easier. Change the tool - runs over to the switch and touches off. A little math and I offset the coordinate system so z0 is the top of the board. Cradek actually uses the same thing but changes the tool length offset. (his way is better) sam |
