[Emc-users] Feedrate in Gui
Can anyone confirm for me that there is something wrong with the feedrate derived from:- emc.stat.settings[1] I thought this displayed the commanded feedrate but if you run a program with varying feedrates in it,the display shows the highest feedrate in the program and not the current commanded feed Try adding different feedrates on to the ends of lines like in arcspiral.ngc When using something like gscreen industrial and watch the F figure. Is there another instruction that will display the commanded feed? I am trying to display the commanded feed alongside the Current Vel (which does work) -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

Re: [Emc-users] Feedrate in Gui
IMHO that is caused, because of the read ahead of the interpreter, The feed you get is not the actual one, it is the one the interpreter last got.

[Emc-users] Feedrate
Hi, Is there any way of multiplying or dividing feedrate? On the little gantry system I have just set up the rotary axis is driven by a microstepping stepper driving a worm and wheel and so, at the moment, G0 corresponds to a feedrate of around 120,000! I want to maintain the input accuracy of the present system but it would be nice to be able to enter the feedrate as a more sensible number rather than having to use F10 or so. I assume I could probably do something with OUTPUT_SCALE but would that affect my accuracy? Also, one of the axes moves correctly under MDI but the reading is reversed in AXIS - is there a way to change this - I can't see one in the AXIS documentation. Thanks, Ian __ Ian W.

Re: [Emc-users] Feedrate
I'm confused by your question, so my answer may be off the mark. In my configuration for a linear axis, I have INPUT_SCALE set to 2048, that is, 2048 steps per millimeter. You need to set that up first for rotary axis, the number of steps per degree. You mention 120,000. Is that 120,000 steps per revolution? If so, that is 120,000/360 steps per degree. Once that is configured, you can set F to be in degrees per min. (or radians, or whatever your preferred unit is) -Original Message- From: Ian W.

Re: [Emc-users] Feedrate
Thanks Brian, That's an idea for scripted moves.. I was really hoping that there would be a more 'permanent' solution, as a lot of the things I do are one-offs where I really only use MDI moves to take advantage of the precision moves possible. I gness its just laziness on my part not wanting to type in big numbers - I'll get over it... Maybe a future version will have scalable feedrate as an option... -- Best wishes, Ian Ian W.

[Emc-users] Feedrate
Hi, I am setting up a fifth stepper axis (B) to drive a lathe head on my little miller and have run into a minor problem. The new ini file is at http://tinyurl.com/yoahtm The axis is working OK and I am getting a reasonable turn of speed out of it for what I want to do but the feedrate I need to enter is ridiculous... I am driving a 200 step motor through an 1/8 microstep driver (Allegro) and the spindle is driven by a 3:1 reduction toothed belt drive. The ini file as it stands allows me to acurately position the spindle by degrees for such things as gear cutting and also turn it at a few hundred rpm for plain turning. However, at its top speed, AXIS reports its speed as 66000 and, to get it to move at that speed, that is the figure I have to enter as feedrate in a G1 move - cumbersome to say the least... So, is there any way I can introduce a divisor into this feedrate figure to get it down to a more sensible figure - it is unlikely I will ever want to turn the spindle at very slow speeds so a divisor of 100 or even 1000 would be great. -- Best wishes, Ian Ian W.

Re: [Emc-users] Feedrate
Ian, What is the feed rate units for the spindle? RPM or Rev Per Sec? My initial look suggests the scale factor (13.333) needs to be much higher. Jim C Ian W.

The INPUT_SCALE is set to rotate the spindle by degrees and I have confirmed that this is what it does by measurement. I need it to work in degrees for such things as gear cutting or milling squares on shafts etc. and I also need to be able to program it to turn a given number of times for threading etc. I am also planning to make a little clock pulse generator so that I can run the spindle independantly of the rest of the cnc for basic lathe turning. maybe use a variable #1=360 G1 B[rpm*#1] Brian - This SF.net email is sponsored by: Microsoft Defy all challenges.
