[Emc-users] Synchronised cam turning
Has anyone tried turning a cam on a lathe using EMC? I tried using lots of G33 moves but they seem to get out of sync. My machine has pretty high acceleration and top speed but even at very low spindle speeds (14rpm) it doesn't seem to keep up. Does EMC have any other way of doing synchronised moves apart from G33/G76? Les -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

Without seeing your gcode, I am going to take a guess that the problem
is one of two things: you have lots of tiny moves, or you did not
properly calculate your K values.
emc's spindle synchronized motion is more or less the traditional motion
planner, but using spindle angle instead of time to control the forward
progress. Specifically, it has the same behavior when there are a lot
of small segments: it will plan each individual move so that it can stop
by the end of that move and stay within machine constraints.
Does EMC have any other way of doing synchronised moves apart from G33/G76?
emc and gcode don't, but of course hal does. You could create a
component which offsets the commanded X according to the spindle angle
and the shape of the cam. The component would include the mathematical
description of the cam shape, r=f(theta)+r0. It would take as inputs
the spindle angle and the commanded motor position (r0), and output the
modified motor position (r)
net Xpos-cmd = camcutter.pos-cmd-in
net Xpos-cam-cmd camcutter.pos-cmd-out = stepgen.0.motor-pos-cmd # or
whatever
net Xpos-cam-fb stepgen.motor-pos-fb = camcutter.pos-fb-in
net Xpos-cb = camcutter.pos-fb-out
net spindle-revs = camcutter.spindle-revs
net cam-enable motion.digital-out-nn = camcutter.enable
In emc 2.3 and above double precision numbers are used for hal floats,
so you can probably skip messing with index-enable and just use theta =
2*pi*spindle_revs for a periodic function f().
In your component, you have something like this:
if(enable) {
double theta = spindle_revs * 2 * M_PI;
double displacement = f(theta);
motor_pos_cmd_out = motor_pos_cmd_in + displacement;
motor_pos_fb_out = motor_pos_fb_in - olddisplacement;
olddisplacement = displacement; // (instance variable)
} else {
motor_pos_cmd_out = motor_pos_cmd_in;
motor_pos_fb_out = motor_pos_fb_in;
}
but this gives a step discontinuity when enable changes. You need to
embellish it with code to slow apply and unapply the displacement. Such
code is in emc/motion/simple_tp.{c,h} in libraryish form. (I'd be
tempted to just copy both into a single header, change simple_tp_update
to be static, and include the header)

I really don't want to keep this going and going, but recently a very dumb person wrote to me with just the intention to insult.

I am not dissapointed with MEsa, i'm dissapointed with the people who advised me. In my country, when */you/* direct someone to buy/do something that gives /*you*/ _.OR._ another an unjustified profit while the buyer/customer/doer gets a dissadvantage /*YOU*/ are responsible. That's called fraud and /*you*/ go to jail. Richard First this is all my personal opinion not the EMC group's. Is an apology you are looking for? I am a member of EMC's development. I, personally am sorry that your experience with EMC was less then what you hoped. I can assure you no one was trying to pull a fast one on you. Certainly no one was trying to fraud you. The hostmot2 software was and is very new. When the person who writes the software tests it it is fairly easy to miss bugs because the person tends to use it as he intended. The more it is used by other people (especially non programmers) the more these are flushed out. As Developers we support this by fixing them as best and fast as we can. Now programmers (as a rule) are just terrible about documentation. Docs are boring - new features are fun. Actually the docs are way way better now then even a year ago, as far as being up to date, correct and usable. But they are just like the software / programmers. When you write them they make sense to you but you knew what you meant! On top of that, in a rapidly developing project it's pretty easy to have the docs (usually just slightly) out of date. We are not perfect - we just try to do our best. On our side, yes maybe we need to evaluate how we release or advertise the state of our software. In fact we have already discussed it in general, to avoid problems. The real problem comes that we think it is right/ bug free because we have tested / used it . But the software is complicated and flexible- we need more people to test / use it. We don't pay people to test. I'm pretty sure profit companies do. So we release it. If and when problems come up we fix them. In most cases the problems that come up are obscure / minor anyways. Usually this works very well-sometimes not so well. I understand it can be very frustrating, it is frustrating for us too- we want people to have success and fun with EMC! But no one likes to be 'beat-up' over these problems, especially if we are not paid to put up with it. We do this because we like the challenge, or like to give back, or like to tinker. So Richard again I am sorry things worked out so badly for you. If you still want help with using the mesa board and EMC we can help but you have to stop the negativity now. Your point is across now To everyone else: We got our point across too - lets move on to some positive energy. If things need changing to help a new person out then lets hear it or volunteer to help do it. If there is problems or disappointments lets get to the point, keep the negativity to the minimum, And lets fix it! I think what this situation is really saying is that EMC is getting heard about- now it's not just the gurus and power tinkers that want to use it, regular people who don't want to invest the time to learn why something works they just want to use it. As far as I'm concerned I say welcome- we'll try to help. Chris Morley _ Attention all humans. We are your photos.

I've prepared a tar that contains your source plus a Makefile and a copy of the modbus source and header from emc. It should work on emc 2.3 (and maybe 2.2) systems with the emc2-dev package installed. http://emergent.unpy.net/files/sandbox/vfs1_vfd.tar.gz you can make or make install (sudo make install on systems where emc is installed as a package) Some of the stuff in that Makefile is far from guessable and that's why I hope to improve this for emc 2.4.

Then put whatever they wanted on the 'triangle' using various methods. Once done, the pathed it, and used the just routed the piece as a plane, using the indexer as the 'x' axis, and the 'y' axis as the indexer. You might be able to take that thought and make your 'unwraped surface' to be the profiles of the 'unwrapped' cams.
