[Emc-users] 4th axis ideas... any suggestions?
Hey guys, I'm going to add a 4th axis to my gettup here on my lagun emc refit, and wanted to ask for suggestions. My plan is (as of now) to find a rotary table on the cheap (ebay, craigslist etc) and mill up a motor mount to it with encoder feedback, and use the 4th channel on my 5i20. I've never even used a manual rot table, so if you guys would be so kind as to make me aware of what I'm totally overlooking here, that would be very much appreciated. I plan on finding a table that can sit perpendicular to the table, like in this video: http://www.dailymotion.com/video/x9a6s1_cnc-turning-on-4axis-mill-with-gala_tech i would also plan on running a lathe-like chuck too... any comments/suggestions/do's&donts???

[Emc-users] Y axis following error woes...
Hello folks, Hope you had a nice turkey day and all. I'm trying to understand why my Y axis following error is so much worse that my x and z. I gave them all equal efforts regarding the tuning process, but Y seems to be much more finicky a mechanical response- oscillations appear to be a serious issue- I can get it down to about a thou of following error at constant velocity but the initial lack of acceleration causes a spike in f-error at the beginning of each move... I've tried toying with FF1 and FF2 as instructed by several of you, but i found that if i deviate from the values I've found, the response goes nuts with skyrocketing f-error.

[Emc-users] Deadband, FF1 and FF2
Hello- I'm having some difficulty tuning my P, I, and D variables. I've used PID before in school, and understand how they are calculated, but I wanted to ask about the three terms I don't really understand... I found in the wiki these explanations: *FF1 = 2.000 a velocity feedforward, helps reduce following error proportional to velocity * * FF2 = 0.25 an acceleration feedforward, helps reduce foll. error when accelerating* However I dont quite understand them- would someone be willing to maybe define the math behind these concepts? and also- is deadband the window over and under 0 volts that yields no movement? does this mean that you can kill steady-state oscillations by increasing deadband?

[Emc-users] Anilam linear encoder output voltage <1v... any ideas?
Hey folks, just inquiring about the output of my anilam linear encoder being less than one volt in amplitude... a full 5v is applied, but the pulses coming out only hit like 0.3vI pulled apart the connector to find some oil in between the pins but wiped it out and still have the same problem. I'd like to ask, when/if encoders begin to die or deteriorate, do they behave like this? I'm gonna do wiring checks to make sure there isnt a voltage drop occuring across a single strand of crushed wire or anything... but i suspect that quite unlikely. thanks! -pat -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Emc-users] 5i20+7i33 connection to Servo Drive has +21mV of drift.
Hello again, first off thank to all the suggestions about the encoders I was asking about. I think I'm just gonna go with the requirement of zero'ing position prior to milling any part. My new question has to do with the servo drive's input. When it should be at 0v, the input to the drive sits at about 21mV, which causes the motor to drift slowly, I though this might just mean the "balance" pot needs to be adjusted, but turning it all the way in either direction has no effect. it's been a while since I've dealt with anything on this level, but I was wondering to myself could this be an impedance mismatch issue? maybe I should try a pullup or pulldown resistor? I read in the manual something about the 7i33 already having one or the other, I'll be lookin into that again today, I just wanted to see if anyone had any immediate suggestions or had encountered this before.

Re: [Emc-users] Anilam linear encoder OUTput...
my photo attachment of the red slide unit was rejected cause it was too big a file. I have a new question though- is it possible that these encoders can be counted on both the rising and falling edge of both signals? in other words: if I count the falling edges on one wire as *640 falling edges per inch*, does this actually mean its *640 x 2* for rising and falling edges? then x2 again for two signal quadrature? or is the quadrature pair only to provide direction information? thanks! -pat On Mon, Nov 9, 2009 at 4:23 PM, Pat Lyons wrote: > red.

Re: [Emc-users] Anilam linear encoder pinout ...
hmmm... looking into what you mentioned- I found this: http://www.anilam.com/anilam.asp?mod=article&actid=67 though I'm not quite sure what type mine are- it says Anilam A10 on it- and look a little different than the SENC ones... thanks again! -Pat On Mon, Nov 9, 2009 at 10:25 AM, EKCo Inc Don Stanley wrote: > Pat; > I have the a SENC 125 T/E linear encoder supplied with a Anilam DRO. > My wire colors are all different but the 5th wire is the R channel. > I think they are sending position reference but haven't checked it out yet. > It is on pin 8 of the 9 pin D connector. > > Maybe this will help >Don > > > - Original Message - > From: "Pat Lyons" > To: "Enhanced Machine Controller (EMC)" > Sent: Monday, November 09, 2009 9:33 AM > Subject: [Emc-users] Anilam linear encoder pinout ... > > > > Hey folks, thought I'd inquire here before plugging them up- > > > > they are anilam linear encoders that appear to have an incremental > output. > > wires are as follows: > > > > Green: ??? unknown... > > Brown: Quadrature A or B > > White: Quadrature B or A > > Black: GND > > Red: +5v DC > > > > I got a daq hooked up to all the wires and basically cant make any sense > of > > the green wire. > > > > it doesn't really do anything, except emit what appears to be a spike of > > noise every now and then that I can't seem to correlate with any specific > > event (im confident in saying it's not an index because it seems so > > random)... > > > > any thoughts on this mystery green wire? > > > > thanks! > > -Pat > > > -- > > > Let Crystal Reports handle the reporting - Free Crystal Reports 2008 > 30-Day > > trial.

[Emc-users] Anilam linear encoder pinout ...
Hey folks, thought I'd inquire here before plugging them up- they are anilam linear encoders that appear to have an incremental output. wires are as follows: Green: ??? unknown... Brown: Quadrature A or B White: Quadrature B or A Black: GND Red: +5v DC I got a daq hooked up to all the wires and basically cant make any sense of the green wire. it doesn't really do anything, except emit what appears to be a spike of noise every now and then that I can't seem to correlate with any specific event (im confident in saying it's not an index because it seems so random)... any thoughts on this mystery green wire? thanks! -Pat -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Emc-users] Some HAL file questions...
Hello- I'm currently reviewing the HAL manual and HAL file for my 5i20. I wanted to ask where the following functions (in bold below) are coming from, as in, where are they defined? where did they come form? I understand that they are being added under the servo-thread, but in the manual it shows you that components have functions in them (viewed with show funct?) that can be added to threads- but what component do these come from? is it from one of these (I'm assuming they're components)? *loadrt trivkins loadrt [EMCMOT]EMCMOT servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[TRAJ]AXES loadrt pid num_chan=3 * I also dont quite understand the use of the brackets [], is this just for notation in the manual? should I be replacing it with some specific names of ini file names or paths in my setup? # # THREADS # addf *hm2_[HOSTMOT2](BOARD).0.read* servo-thread addf *motion-command-handler * servo-thread addf *motion-controller * servo-thread addf *pid.0.do-pid-calcs * servo-thread addf *pid.1.do-pid-calcs*servo-thread addf *pid.2.do-pid-calcs * servo-thread addf *hm2_[HOSTMOT2](BOARD).0.write *servo-thread addf *hm2_[HOSTMOT2](BOARD).0.pet_watchdog* servo-thread # ## thanks! -pat -- Come build with us!

[Emc-users] Need Help - what's the process for getting my 5i20/7i33 setup going?
Hello- This mailing list has helped me figure out how to get rolling on a few matters already, so thanks much for all the info sharing! My questions now pertain to what steps I have to take to get my 5i20 and 7i33 mesa hardware working with emc2. This first one may be dumb question, but I'm failing to figure it out alone... I'm hearing about this pncconf utility that apparently is a graphical wizard for getting the 5i20 card configured with one's particular setup. how do I get into pncconf? I cant find any files anywhere labeled pncconf, and it's not in the configuration selector list. I've got loads more questions, but I think once I get into pncconf they may be answered, so I'll spare you till then. Thanks for any help -pat -- Come build with us!

[Emc-users] EMC2 / OS implementation
Hello- I'm currently trying to setup my emc2 based controller while waiting for my mesa cards to arrive, and I have some questions. Here's what I'm looking to do: I want to push the startup button on the computer case and have the screen present login prompt via command line. upon logging in I want emc2 to startup in some simple window manager like xwindows or something (fluxbox?). what are the steps I would have to take to do this? I used to be a command line junkie back in the day but I've forgotten almost everything I knew... so this n00bery I'm exhibiting here is extra frustrating to me.
