I will have to reply to this later tonight, my machine is not here, I do know that I installed that computer about 4,5,6 months ago from a freshly downloaded CD from EMC (latest version) and it sat in my house till I got it out to the machine a couple of weeks ago. I don't know what I used to set up the hal pins, this is what I will look at tonight. I think I created a shortcut that is going to the (ini?)files that I am using to start emc. Tonight I will go and clear my config files and run the setup per the tutorial John pointed me to and I will let you know the results. On my other setups I have not had to run this I have just went in and modified the .ini file and stayed with what thought was a standard pin out on the LPT port.

Is there anyway to add this as a feature?

This is from EMC1 interpreter experience, so some terms may have changed.
The ini file access point for the interpreter (in EMC2) was at one point in
rs274ngc_pre.cc, where you should find a function like ini_load(const char
*filename) which grabs the interpreter related ini stuff.
Declare the variable in canon.hh, and copy/paste the existing parameter grab
in the ini_load() function and modify it to get/test the ini variable you've
created.
To remove the M02 effects, look at convert_stop, in the interp_convert.cc
file. A simple if (!your_ini_flag_variable){m02_code_here} around the m02
conditional code should do the trick for what I think you're asking.

The first is get a resolver to quadrature converter box. With such a box you get the signal generator to power the resolver and a fixed number of pulses per rotation of it. You could also replace the resolver with an encoder. This is what MattS and I did with a Hardinge lathe. He had a little spindle built that matched the size and arrangement of the Harosun(sp) resolver and mounted a shaft encoder on top of it. Thats the plan for a Hardinge CHNC I picked up cheap, I have a couple of ideas on turning the turret but don't mind suggestions! Okay. Let's say now that you've got quadrature feedback of axis and spindle position. Now you need a way to get those signals into the PC running EMC2. Several board makers have devices that can do this. EMC has HAL driver modules that can read these. In alphabetical order, some of these include. Mesa, Pico, Pluto, STG, Vigilant, Vital. You'll find links to these companies at www.linuxcnc.org. And lastly you will have to produce a velocity signal of the sort expected by the motor's drive amplifier. In that age most of the drives used an analog signal that varied between -10v and +10 volt. Again the board makers will usually have that ability as well. I have schematics of this part if needed. Ed.

I never saw a stepper used for axis positioning until much later. They were used to pace the tape through a tape reader during that time. Let's assume that you've got servos. Next issue is the nature of the position feedback. Many of the machines from the the seventies and eighties used resolvers rather than pulse coders. A resolver does not produce pulses that can be counted. A resolver uses ac rather than dc power. They take two ac signals, sine and cosine to each other and return the rotor position as a phase shifted signal. My experience suggests that one way you can tell a resolver is that the six wires from it were twisted in pairs. If it was placed in a can with a plug, good luck figuring it out.

With such a box you get the signal generator to power the resolver and a fixed number of pulses per rotation of it. You could also replace the resolver with an encoder. This is what MattS and I did with a Hardinge lathe. He had a little spindle built that matched the size and arrangement of the Harosun(sp) resolver and mounted a shaft encoder on top of it. Okay. Let's say now that you've got quadrature feedback of axis and spindle position. Now you need a way to get those signals into the PC running EMC2. Several board makers have devices that can do this. EMC has HAL driver modules that can read these. In alphabetical order, some of these include. Mesa, Pico, Pluto, STG, Vigilant, Vital. You'll find links to these companies at www.linuxcnc.org. And lastly you will have to produce a velocity signal of the sort expected by the motor's drive amplifier. In that age most of the drives used an analog signal that varied between -10v and +10 volt. Again the board makers will usually have that ability as well.

Re: [Emc-users] Abort messes up position
Okay, I did some more testing today, here is what I did and the results starting machine location was (-2,2,.5) from where I want the (0,0,0) position to be I turned the machine on Started emc hit f1 and f2 right clicked on the x axis position number to pull up the position change box typed in -2 pressed enter right clicked on the y axis ... typed in 2 pressed enter right clicked on the z axis .. typed in .5 pressed enter pressed f4 loaded a program pressed r after the machine was running for a little bit I clicked abort pressed f5 typed in g00 x0y0 pressed enter the machine went back to the original start up position of (-2,2) and the displays read (0,0) so I promptly reset my zero positions as I did above and repeated it, and it did it again.

My base_period is currently at 11000 I can't go any lower Sorry, I was thinking in terms of frequency, not period. 11000 is pretty fast. Assuming you don't have any special timing requirements, that means you can generate one step every 22uS, or 45,000 steps per second. Since you didn't say how many steps you need to reach the desired speed, I don't know if the problem is: A) you need 60,000 steps/sec (ain't gonna happen), or B) you need 30,000 steps/sec, and we need to figure out why you aren't getting that many.

Okay I think I have it, It works better after doing both the velocity and the accel. Question, when I was running EMC 1, I would have problem with following errors if I went above 100% on over speed of the axises while running a program, what causes this and how can I fix it? Can I test this without running code? if so how? Andy John Kasunich wrote: Replying to myself: John Kasunich wrote: Do you have adequate stepgen headroom?

Re: [Emc-users] [Fwd: Jog wheel ?]
Thanks for the help John, now all I need to do is get emc II up and running on my machine :-) Andy John Kasunich wrote: Andy Holcomb wrote: http://littlemachineshop.com/products/product_view.php?ProductID=2938 Yes. Can EMC II use a jog wheel yet? If so what is required? A jog wheel. The ability to count the pulses it makes. Hardware pins to get the pulses into the system. A few lines of HAL code to hook it up. The wheel you linked to has 40 counts per rev which is typical. Assuming you aren't going to spin it faster than 10 revs per second, that works out to a maximum of 4000 counts per cycle. EMC2 can easily count that speed in software. (The limit is probably more than twice that, even on a slow PC.) So all you need is two free general purpose digital input pins. Parport pins work fine, as do extra inputs from motenc or mesa cards, or a variety of other general digital input cards (8255 based, etc). The Pico systems boards (USC and UPC) have opto-22 modules on most of their I/O, which isn't good for encoder signals. However, those boards have 4 encoder channels. If you have a three axis mill, or a 2 axis lathe with spindle encoder, you should still have an encoder channel free to count the jog wheel. Using a hardware counter to count 4000 counts per second is overkill, but if its there, might as well use it. You can do a variety of things with the jogwheel. AXIS provides HAL pins that can be used to make the wheel control whatever axis is selected in the GUI. I'm not sure if the other GUIs can do that or not. You can also select the axis to jog using onscreen buttons with pyVCP, or real buttons and/or selector switches. You can also select different scale factors, again with onscreen buttons or real ones. For example, you could select between 1.000 inch per rev (0.010 per click) and 0.01 inch per rev (0.0001 per click). If you rich and have three wheels, you can hook one to each axis permanently.
