EMC does receive encoder signal from servo drive (motors have resolvers, servodrive emulates encoder signal and outputs it on a 9-pin serial port connector, from where the signal is wired to 7i48). I am watching position pins of encoders from servo drive and they either increase to very high values or decrease to very low values. Actually EMC receives all 6 encoder signals, also 3 from linear scales - I also checked their position pins, when pushing machine by hand (motors are detached) and it seems that the increase/decrease in the value of linear scales' position pin matches the actual travel. I have 2 questions: 1) I have managed to get 2 joints oscillate around zero, (which tells me that they need have PID parameters adjusted). There is a problem with a third joint, which just runs away. When I try to change something for that third joint, it affects also some of first two. Why is that so? For example, if I set Output_scale for third joint from 1 to -1, second joint will not oscillate around zero, but run away. 2) How do I solve the situation, when PWM value is +1, but encoder position increases in negative direction? That is for the third joint. As I mentioned, changing output scale to -1 for third joint will make second joint to misbehave. What else can cause that? Should I change A and B wires from encoder signal cable?

For example, if I set Output_scale for third joint from 1 to -1, second joint will not oscillate around zero, but run away. There should be no interaction of the axis I would do as I has suggested and verify that all DAC channels work as expected before proceeding. interaction suggests a grounding/ analog input problem (do the drives have differential inputs ( most do) If so the IN+ sould go to 7I48 AOUT and the IN- to 7I48 ground Thanks, I will take a look! 2) How do I solve the situation, when PWM value is +1, but encoder position increases in negative direction? That is for the third joint. As I mentioned, changing output scale to -1 for third joint will make second joint to misbehave. What else can cause that?

I would first set up the encoders so they count in the correct direction for your axis, and then change the output scale to reverse the PID feedback if need be. Ok, and how can I do that - fix the the direction of counting? Will changing A and B leads do the trick?

Usually you set the drive velocity scaling to match the max velocity that you want to be able to spin the motor up to. Say you want 1000 ipm as the absolute max velocity for that axis, figure out what your motor must spin to do that (via the gearing) and that is your max motor velocity for 10V. EMC uses all of the edges - at least that is my experience when using the Mesa cards and hostmot2.So it is the pulses per rev for the encoder x 4 when using quadrature mode on the encoder inputs.

The package manager can find EMC2 just fine, but nothing similar to hostmot2. Do I need to add a repository to the list?If so does anyone know the URL for the hostmot2 package repository?

I just added the source line into the list of other repositories in

I was very close in my previous guess, but I left base off the end of

Apparently close does not count. ;-)

The firmware downloaded and installed properly.

Re: [Emc-users] Beginner questions regarding axis.
John, Welcome to EMC2! I can't answer all of your questions, but I will share my homing experience: a CNC mill homes every axis from the standpoint of the tool and all movement during homing is positive. This means the table moves to the left and toward you, and the spindle moves up. Now your tool is at the right, rear, and top of your work envelope. This is Machine Zero. Every move from this location is negative. Enjoy! Jim - Original Message - From: John A.

Brian, Kirk, James; This is all making sense now - lots of good action happening downstairs. :-) Also check your G540 for the micro step setting to be sure it matches the values in your INI file that Kirk was referring to. Ok - just checking the microstep settings - the Gecko gives 10; the stepconf defaulted to 2; that'll probably be the last thing. I did manage to manipulate the ini file (thanks for the pointers and math) to give me the right movement, but would like stepconf to do this for me. I think tomorrow morning I'll be up and running.

Do I need to add a repository to the list?If so does anyone
know the
URL for the hostmot2 package repository?
The apt source is:
deb http://linuxcnc.org/lucid lucid base
Put that line in a file named /etc/apt/sources.list.d/linuxcnc.list
Then run apt-get update to fetch the package list.
The packages are named hostmot2-firmware-{all|BOARDNAME}, run
apt-cache
search hostmot2-firmware to get a list.
Are the .PIN files no longer included with the .BIT files?
I see some XML files now.
They're included in the hostmot2-firmware-5i20 package at least. I
don't know about the others.

OK.. they are installed in the /usr/share/doc directory.. I found them.

Andy, The edit seem to have fixed it!! Now all I need to do is figure out the video driver. . . Keith Hoard Collierville, TN kho...@gmail.com It is a software adjustment. The wiki page does describe what to do (It is just a case of editing rtapi.conf in the current version of EMC2. ) http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingSMIIssues -- -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users End of Emc-users Digest, Vol 65, Issue 40 * -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Beginner questions regarding axis.
James Louis wrote: John, Welcome to EMC2! I can't answer all of your questions, but I will share my homing experience: a CNC mill homes every axis from the standpoint of the tool and all movement during homing is positive. This means the table moves to the left and toward you, and the spindle moves up. Now your tool is at the right, rear, and top of your work envelope. This is Machine Zero. Every move from this location is negative. Enjoy Well, there is no reason it has to be this way. Full up for the spindle is a good choice, and G-code defines that as the positive direction. But, on my Bridgeport, the X home is near the center of table travel. The machine coordinate system really is of no use except for defining limits of table travel, and possibly for safe positions for tool change, etc. So, the machine coords are of use to internals of EMC, but the user never needs to know about that coordinate system. What the user needs are the workpiece coordinate systems, and when you position to a place relative to the part and take measurements with gauges, edge finders, coax indicators or whatever, then you set the work coordinate systems, generally with the touch off feature in Axis. EMC takes care of figuring out the mathematical offset between the machine coords and the selected workpiece coordinates.
