| CNC router table... |

| John Hill:
I have put my two cylinder atmospheric engine aside until the cooler weather and started on a project to build a CNC router table. The table is quite big, about 900 x 2000mm. It will be that size because that is the size of the warehouse racking components I was given. I have a few steppers and all the control equipment but I do worry that X axis will need a lot of drive however I have received a driver for 3 phase steppers which I have tested with a Fisher and Paykel washing machine motor. This is what the motor looks like.. Testing with EMC2 and a 36 volt power supply the motor turns with enormous torque but quite slow to accelerate and a top speed of, estimated, less than 200 rpm. The motor has only 42 steps which would be rather coarse for any direct drive but maybe it will be usable with the endless chain concept I posted at http://www.cnczone.com/forums/linear-and-rotary-motion/254308-cable-chain-belt-drive-concept-long-axis.html |

Hi John I have some of that cooler weather that you are waiting for. Send me up a container of hot air and I will fill it up with nice Cold Arctic Air and return it. That should be enought to keep the shed bearable. :lol: :lol: Keep us posted on MadModder John as I'm sure you will find a good amount of interest with your cable/chain/belt drive concept. Cheers :beer: Don |

Another interesting mad mod, John! Looking forward to it. :coffee: :coffee: :coffee: :coffee: Don, I think you sent your weather down here by mistake......... :) |

John, Are you planning for a rigid gantry and a moving table or the other way around? Eric |
| John Hill:
Eric, fixed table and moving gantry. |
