I apologize, I missed the attachment. The hal file shows that you are NOT using halui for jogging, only for some on/off stuff like machine on, pause, and resume. That explains how you were able to get analog jogging to work without using CVS head. So, lets figure out what isn't working. Start EMC, then open a shell (terminal window), and start halcmd using "halcmd -kf". That will get you an interactive session with a halcmd prompt: halcmd: start two halmeters: halcmd: loadusr halmeter halcmd: loadusr halmeter halcmd: On one of the meters, click the select button. When the dialog comes up, click the signals tab. Select the signal "velX" from the list, then click OK. That signal is the output from the joypad, going to a simulated encoder. On the other meter, click select, then the signals tab, then select the signal "countX" and click OK. That signal is the counts from the encoder, going into EMC's motion controller. Now try jogging with the joypad. When you move the stick away from center, VelX should become non-zero. The farther you go, the larger the value. Full deflection on the stick should give you plus or minus one. If that is not what happens, the problem is in the joypad or the joystick driver, or the connections to the driver. "show sig vel" should show you the signals, so you can verify that the right pins are connected. If velX looks OK, then check the other meter. countX should be constant (not neccessarily zero) when the stick is centered. As you move the stick away from center, countX should start changing. With the scaling you have in your file, countX should change by about 500 counts per second with full stick deflection. If you center the stick again, countX should stop changing. If that is not what happens, the problem is between the joypad output and the encoder output. Use "show sig X" to verify signals XA and XB are connected properly, "show sig countX" to make sure that countX is connected to the output of the encoder block. If countX looks OK, then its time to look at the motion controller. "show pin axis.0.jog" will show you the jogging related pins. jog-counts should have the same value as countX. jog-enable should be TRUE. jog-vel-mode should be FALSE, and should be whatever you have set as the "jog distance per count". In your case, it is either 0.1 or 0.01, as selected by two joypad buttons. You can check that by clicking select on one of the halmeters, clicking the "pins" tab, then selecting "axis.0.jog-scale" and clicking OK. The value on the meter should be either 0.1 or 0.01, and should change when you push the appropriate joypad buttons. I think I see the problem... (maybe). You have the scaling set up so that it will move either 0.1 or 0.01 units per count, and it will generate 500 counts per second at full deflection. Are your units inches or mm? If they are mm, then 0.1mm per count and 500 counts per second means 50mm/sec, or 3 meters/minute. If it is inches, 0.1 inches per count means 50 inches per second or 3000 inches per minute. A moderately fast machine can move at 3 meters per minute, but I doubt any machine can move 3000 inches per minute. If the scaling results in a ridiculously high jog rate, the position commanded by the jog is going to get way ahead of the machine. So when you let go of the stick, the machine is going to keep going, trying to catch up. There are two ways to deal with this problem. First, set more realistic scaling. If this is an inch machine, with rapid speed of 180 inches/min (3 inches per second), then set the high scale to 0.006. 0.006" per count times 500 counts/second = 3 inches/sec. Set the low scale factor ten times smaller, 0.0006 in this example. The other thing you might want to do is switch the jogwheel input into velocity mode. Unlike a real jogwheel, a joystick doesn't deal with position anyway. If you set axis.0.jog-vel-mode to TRUE (setp axis.0.jog-vel-mode 1), then the commanded position will not be allowed to get far ahead of the machine. When the counts stop changing, the machine will stop moving right away. Please let us know what you find! Regards, John Kasunich - Take Surveys. Earn Cash.

Re: [Emc-users] Show us your pics of unobtanium!
Hi Dean, Gene, This is coming from a Toolmaker and I also make guitars. If it were metal I'd say yes all but the final finish could be done on the machine. Knowing wood the way I do I have to say Dean is right about the tearout. As a toolmaker and woodworker I understand first hand that just need to be done by hand with a file. If you look closely at Deans picture you can see little bits of tearout with just that small cut.

Looking at the code, I see that older versions of the PPMC might not export the index-enable pin. If you load the driver and "show pin ppmc.0.encoder.02" shows an index pin but no index-enable pin, your board is an old version that doesn't properly support indexing. You should contact Jon Elson for an upgrade in that case. Looking at the code also leaves me rather convinced that the index pin should be removed.

I know that seems harsh, and its not your fault that you are using it, so please don't take that the wrong way. Let me explain: The linkpp command was added as a shortcut to easily link two pins together. The normal way to do that was (and still is): # create a signal newsig some-meaningful-name whatever-type-the-pins-are # use the signal to connect the pins linksp some-meaningful-name the-first-pin linksp some-meaningful-name the-second-pin The result of those three commands is a signal with a name that means something, connecting the two pins. The linkpp version of that is much shorter and more convenient: linkpp the-first-pin the-second-pin That is equivalent to: # create a signal newsig the-first-pin whatever-type-the-pins-are # use the signal to connect the pins linksp the-first-pin the-first-pin linksp the-first-pin the-second-pin You still wind up with a signal connecting the two pins, but now the signal is named after the first pin. Having a signal and a pin with the same name is legal, but very confusing. In hindsight, 'linkpp' is an abomination that should never have been invented. We now have a much better "shorthand" way to connect two (or more) pins, the 'net' command: net some-meaningful-name the-first-pin the-second-pin The above line is equivalent to the very first example - it results in a new signal with a name that means something, connecting the two pins. > this gives me the error as follows > > HAL: ERROR: signal 'axis.2.index-enable' already has output or I/O > pin(s)HAL:14: linkpp failed > > halshow shows the axis.2.index-enable pin connected to axis.2.index-enable > halshow shows nothing connected to ppmc.0.encoder.02.index > > ### > > linksp Zindex axis.2.index-enable > linksp Zindex ppmc.0.encoder.02.index > > ### > > linksp Zindex ppmc.0.encoder.02.index > linksp Zindex axis.2.index-enable > > ### You get points for persistence - you've tried three different ways of connecting those two pins. Unfortunately ppmc.0.encoder.02.index is not the pin you want. In my last email I wrote: > there should be a HAL pin from the driver called > ppmc.N.encoder.M.index-enable index-enable, not index. Connect the ppmc index-enable to the axis index-enable (use newsig + linksp, or net, not linkpp). I have no idea what the ppmc 'index' pin does. Jon Elson, do you know? It is not part of the "canonical encoder interface", and it is just causing confusion. If there is no good reason for it, it should be deleted. > What am I missing, besides gray matter and a clue? :) No, you were led astray by a confusingly named pin.

[Emc-users] axis homing
Gentlemen, I had read the manual about the axis.N.index-enable. I had tried these commands. I am working with my Z axis as this is the easiest to reach. ### linkpp axis.2.index-enable ppmc.0.encoder.02.index this gives me the error as follows HAL: ERROR: signal 'axis.2.index-enable' already has output or I/O pin(s)HAL:14: linkpp failed halshow shows the axis.2.index-enable pin connected to axis.2.index-enable halshow shows nothing connected to ppmc.0.encoder.02.index ### linksp Zindex axis.2.index-enable linksp Zindex ppmc.0.encoder.02.index this gives me the error as follows HAL: ERROR: signal 'Zindex' already has output or I/O pin(s)HAL:21: link failed the first command is successfull and halshow shows the axis.2.index-enable pin connected to Zindex. The next command fails, gives me the error feedback and doesn't connect ### linksp Zindex ppmc.0.encoder.02.index linksp Zindex axis.2.index-enable this gives the error as follows HAL: ERROR: signal 'Zindex' already has output pinHAL:21: link failed the first command is successful and halshow shows the ppmc.0.encoder.02.index pin connected to Zindex. The next command fails, gives me the error feedback and doesn't connect reversing the second command to "linkps axis.2.index-enable Zindex" gives me the error HAL: ERROR: signal 'Zindex' already has output pinHAL:28: link failed ### I restarted EMC between each test to make sure I had no carry over and I have been unable to find a combination that works. Maybe I should have asked this question more specifically the first time but I thought I was missing something and didn't want to lead the answer to the conclusion. What am I missing, besides gray matter and a clue? :) thanks Stuart - Take Surveys. Earn Cash.

Re: [Emc-users] Joypad problem with version 2.1.4
Uhm, mine did not work with 2.1.2 and 2.1.3 but now with the 2.1.4 works fine. Please post your hal file.
