hi all, there you all go again with all your emc vs/ mach thing again... :-) when are you people gonna bother about cutting stuff ?( ok,i am just joking,please...
http://www.youtube.com/watch?v=3_qdZB9iGhU i am basically building the same now for cnc showroom purposes. should i expect even faster ,better performance if i...
Having used both steppers and servos on various machines, I'd go with servos if your budget allows. Either will get the job done, but with servos you have the...
i am a little bit anxious that i am looking for trouble and complications by going servo.i almost never see anyone complain about the g203v,and judging from...
... I debated the whole steppers vs servos thing for awhile. After talking with folks who are using their cnc's for applications similar to mine, I concluded...
... a showroom model that cuts and carves in front of big industrialists. they are into melamine furniture,carved furniture,and concrete casts mould making. ...
... The video said 5 m/min in one shot, and 3m/min in another. I did not see any motion that loked over 1 m/min to my eye, but didn't have a really good scale...
... Good points! The two places servos shine (it really boils down to the same point) is in its ability to handle a wider range of speeds. That affects a...
so basically,could someone recommend a servo package from homeshopcnc for that piece of machinery? i suppose i will need 7:1 gearboxes...where to get those?i...
... Ray, I have a BP clone CNC machine currently using big size 42 steppers, it works fine but I'm considering moving to servos to get better performance. Can...
I've been down the road of building a Stepper powered unit, and then moving to a servo driven one. Personally, I'll never go back to steppers. I was scared of...
thanks jarrett. so,what was your technical level when you moved to servo? did you have any problems? whats the reduction ratio? what voltage do you operate on?...
No problem. I'm not sure what you mean by 'technical level'. I was having problems w/ the steppers losing position. I swore I'd never wreck a multi day job w/...
Personally, I see no more "complication" with servos than with steppers. They both have good points and bad points, and things you need to know about to use...
Last I knew, Rick only sold one servo motor - 850 oz-in, which are the ones I just put on my knee mill. I couldn't be happier with them, and on a machine like...
Paul, I used the 850 oz-in servos from homeshopcnc.com, with G320s. I have 2.5:1 belt reducers, 4-pitch ballscrews, and a 70V supply. Right now, I'm limited...
Someone mentioned Yaskawa drives earlier in this thread, presumably meaning AC servos. If you wanted to compare them against a lower cost AC drive, you may...
what i am looking for: situation: generic high performance motorisation package for 8 by 4 feet router tables estimated market : 4-5 total. rivals: gerber...
I'm new to CNC conversion. I'm converting a Grizzly X3 bench mill to CNC and am having trouble getting my servo drives tuned in so they have enough torque....
Try this: 1) Turn current limit all the way up. Set Gain and Damping to 9 o'clock position. See how it works. If it doesn't work smoothly here, you've got...
... I agree. Get toothed belt pulleys from the usual suspects, SDP/SI or WM Berg. (Maybe even McMaster-Carr will sell to Mauritania) The "boxes" can be...
now that i think of it,stewart platform algo is very simple.no need for hessian etc... view the mobile platform as a triangle. each vertex of the triangle is...
I do mainly raster milling... SLOW I spent quite a lot of time and handfuls of $ trying to get faster speeds. End results were marginal except for the piles of...
yup,its actually 2 machines on one bed. g-code is not generated by a cad program.its generated on the fly,before each new work starts. the art works are...
is it mathematically and electronically feasible to resample the step pulse train at 192 khz,then time shift it ,to give a jitter free pulse train,before...
... Uh - I think that article has nothing important to say about step pulse streams. As to the original question, I don't know that an outboard re-timer would...
