Hi all; Hope this question is considered on-topic, or at least not too far off.
I'm doing another CNC conversion - my largest yet. G0704 (BF20) style mill, and I'm wondering about stepper drivers. (Have a Mesa 5i25/7i76 combo; maybe my next machine will be servo) I'm wondering about drivers - I have as spares a Gecko G540, some 48v 7.5a switching power supplies, a couple Gecko 3.5A drivers (the ones in the G540, but standalone) but wondering: 1) digital drivers, eg automationtechnologiesinc.com ones, are they worth the price? 2) China drivers look the same as 1); presumably the technology is the same, just name-badging; 3) Europeans seem to use smaller steppers than North Americans; is there much savings (e.g., power, heat) from using smaller steppers? I'd guess so. I'm in Canada, so shipping from the USA or China or Europe is about the same - expensive - so source location is not an issue. It does seem a shame to purchase new drivers and power supplies, but I might as well do this machine "right". Thanks for any insights you might give. John A. Stewart. ------------------------------------------------------------------------------ Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
