Just a quickie. Can anyone recommend a UK supplier of stepper motors and associated drive electronics? eg just add mill, and computer running EMC.
Mill is a light / middleweight Pinnacle universal job, XYZ travels are 400, 180, 150 mm with quill head having separate raise / lower facility and rotation about X and Y axes too. Buying a DRO today with GS500 series glass scales (5 micron) from www.machine-dro.co.uk so will hopefully be able to use output from linear scales as direct input into EMC computer, (phase 2 of the upgrade) max rapid speed of the scales is allegedly vastly in excess of anything I could need, so don't need 740 watt steppers... X table may weigh 200 lbs and perhaps another 150 for Y table, not trying to pull high G accelerations and a rapid of 300 mm per minute would be double what I'd be happy with. On a budget of course (aren't we all) but definitely prepared to pay a little more for something not prone to glitches such as interference on power rails etc causing missed steps. Doing it this way appeals to me for two reasons. 1/ redundancy, can use linear scales with either EMC computer or standalone DRO at will. 2/ eliminates backlash and screw mapping etc, linear scales will measure actual position of tables and quill. many thanks in advance. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
