It is called python-setuptools mea culpa. However it appeared that the previous command: sudo apt-get install python-pip may have installed the setuptools I ran it on the local PC browser that already had LinuxCNC installed running on Ubuntu 12.04, and it works fine and is very fast. The PC was plugged into my home network that has a wireless router attached. I pointed a Nexus 7 tablet running firefox at the LinuxCNC PC and the DROs display nicely on it and the update is very fast. Much faster than I expected. I installed Apache prior to loading your example, thinking that was required, but Cherrypy is a web server itself, which I did not realize, and Apache is not doing anything. Yes due to the lack of websocket support. This would probably help: https://github.com/disconnect/apache-websocket But it is much more difficult to setup. My instructions was not clear. Sorry. Very nice. Thanks, Dave Thank you for the feedback and testing the tool. :) Matsche Matsche, It took me about 15 minutes to get it up and running. I didn't even install the python-setuptools and it still worked! So when I installed Apache2 that probably installed the websocket support also at the same time? Everything just came up and ran!

Just wondering how long before we see this in mainstream Linuxcnc.
In particular on the beaglebone.?
Everything i do is programs generated from cam systems with lots of
little G01's and G03's.
And the current TP really does make a meal of it.

Hi Chris - Here's part of the code - it's obvious early on without all
of it. I'll post the config tomorrow - machine is at work.
BTW - Changing N190 to

Re: [Emc-users] Poor CV
Oh well.. no joy. ;-)
Its pretty hard to argue with all of the graphs you made.
Mach4 will fix all these problems.
That was the mantra for a while, but I think that reality has slowly
sunk in.
I hope that all of the Mach4 work they have put in, pays off eventually.
It has taken a long, long time and it still is not released the last I
looked.
I doubt Steve will switch - jog while pause seems to be a real show
stopper for him.
I thought that Steve was using the jog while pause tweak that Les wrote
up a while ago.
There is also Micheal's solution which I have not tried.
I see that the USBCNC controller he is using does do jog while paused.

If you calculate it out - it is about 3600mm/min. that is the commanded

[Emc-users] Servo system oscillating feedback
I installed a Mesa 5i25 with 7i77 to drive a Minibravo 60 Brushed DC motor drive. It drives a Brushed DC motor (ESA 3M 8019) from Motor Power Company. There is a encoder fitted to the motor. Also an ESA 3Mxx? There is a 10:1 planetary gearbox fitted to the shaft. The Minibravo's are designed to work with a tacho and has a tunable PID interface when using the tacho. These drives are fitted with an encoder interface board that turns the pulses into an analog voltage that is supposed to be representative of the rpm of the motor. When the encoder option is used it seems that the PID is not in circuit. The problem is that I get a constant severe oscillation when the motor is in rest as well as when it is driven. When I scope it with Halscope, I see the constant ripple on the feedback count as well. If I remove the analog input signal to the drive, I still get the oscillation. Has anyone have any experience with this kind of setup. Your assistance will be appreciated :) -- Regards /Groete Marius D.

Re: [Emc-users] Servo system oscillating feedback
Hi Peter That is what I did but it seems that no matter how I turn the variable resistors (multi turn pots) they oscillation remains as strong. There are some instruction on tuning the drive when using a tacho but nothing for the encode option. I even tried to remove the feedback to the drive and go through LCNC for the PID loop. I still cant get rid of the oscillating feedback The customer has a set of drives that was supplied by Mesa and I wondered how you would go about connecting the setup if I had to remove the drives and replace them with the Mesa drives. I dont know if these Minibravos are such great drives as I have never encountered them before. On 2014-03-04 21:50, Peter C.

[Emc-users] EMC Configuration
Hi, Folks; I’ve just joined this list, but have been using EMC for a few years. I’m using Rel 2.3 and am attempting to use the configuration software. Of course, this is an iterative situation. I’m using the stepper configurator. I prefer to use the mini GUI and would like to allow an override of 100% (That is, allow me to double any of the defaults) 1. Is there any way to get the stepper configurator or some other utility to set the Display Override settings in the .INI file? It’s no issue to continually edit the INI file, but it does get old after a while. 2. Barring that, is there any way to get the stepper configurator to simply ignore settings that it does not modify? It’d be nice to have the configurator read the INI file, modify those items which it allows the user to set, and then rewrite the INI file without reverting anything not changed to the default?

Re: [Emc-users] Servo system oscillating feedback
Dave I disconnected the 7i77 from the drive completely. It should stand still with no input but it oscillates and the adjustments made no impact at all. On 2014-03-04 23:43, Dave Cole wrote: Try disconnecting the 7i77 entirely from the drive and hook a constant voltage source to the drives input - I oftentimes use a 1.5 volt battery ( an isolated voltage source ). Disconnect the load from the motor so the shaft can turn freely. There should be some instructions for tuning the drive like this as a velocity mode drive. Run the motor in one direction, then reverse the battery to run it in the other direction. See if you can tweak the drive so that it runs smoothly, and at a constant speed. If the drive is not stable using the battery, it will never be stable hooked up to the 7i77.

There are some instruction on tuning the drive when using a tacho but nothing for the encode option. I even tried to remove the feedback to the drive and go through LCNC for the PID loop. I still cant get rid of the oscillating feedback The customer has a set of drives that was supplied by Mesa and I wondered how you would go about connecting the setup if I had to remove the drives and replace them with the Mesa drives. I dont know if these Minibravos are such great drives as I have never encountered them before. On 2014-03-04 21:50, Peter C.

It drives a Brushed DC motor (ESA 3M 8019) from Motor Power Company. There is a encoder fitted to the motor. Also an ESA 3Mxx? There is a 10:1 planetary gearbox fitted to the shaft. The Minibravo's are designed to work with a tacho and has a tunable PID interface when using the tacho. These drives are fitted with an encoder interface board that turns the pulses into an analog voltage that is supposed to be representative of the rpm of the motor. When the encoder option is used it seems that the PID is not in circuit. The problem is that I get a constant severe oscillation when the motor is in rest as well as when it is driven. When I scope it with Halscope, I see the constant ripple on the feedback count as well. If I remove the analog input signal to the drive, I still get the oscillation. Has anyone have any experience with this kind of setup. Your assistance will be appreciated :) -- Regards /Groete Marius D. Liebenberg +27 82 698 3251 +27 12 743 6064 I would expect that there is a PI velocity control loop in the drive that takes the simulated tachometer signal as the velocity feedback. If the driver/motor oscillates without any feedback from LinuxCNC you will need to lower the drives P/I gains until it is stable before proceeding.
