Re: [Emc-users] Parport stepper setup
Thanks everybody for your replies, they have given me the direction that I needed. I think it may take a couple of days or weeks for me to research all the options and progress to the next step. Cheers Colin _ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Colin Sent: Monday, 8 January 2007 9:49 PM To: emc-users@lists.sourceforge.net Subject: [Emc-users] Parport stepper setup Hello, I have been investigating using EMC2 and some stepper motors to a small milling machine. I have a cloudy area of understanding around driving the stepper motors. As usual I am trying to do it on the cheap :-) and hence would like to develop my own stepper driver. I am hoping someone can provide some direction so that I don't fall off any cliffs. So far I believe there is two ways to generate an amplified stepper signal (half, full etc). Method 1 Using the parport config to send a step signal and a direction signal for each axis. Run these signals into a stepper driver chip which is configured for the stepper phase that I require. This method should leave a few extra pins on my parallel port to play with later. Method 2 Use the functionality of the stepgen module to perform the required stepper phase for each axis. Amplify each signal into the motor. This method will use up more parallel port pins depending on the amount of coils in the stepper that I purchase, I may even need another port if 5 phases is required. Are both methods possible? Which method is the most common or gives the best result? I also intend to opto isolate the signals coming from the parallel port to protect my motherboard, is there any unforeseen problems doing this? Cole - Take Surveys. Earn Cash.

[Emc-users] 5I20 card type 2!
Hello Mesa electronics preparing to introduce new card 5I20 type 2 sometimes with in next 6-8 weeks. Question, will 5i20 and 5i20 type2 be interchangeable? 5i20 type 2 card will have 4 connectors 50 pins each. Mesa electronics also want to manufacture Ethernet type communication between computer and servo drive. Another question, is EMC2 prepared for that type innovation? I am interesting in EMC workshop 2007, when in schedule to happen. Thanks AramK <>- Take Surveys. Earn Cash.

Re: [Emc-users] adding 2nd parallel port
Anders, Thanks, that's good info. After looking at the HAL_Documentation again... The answer to my question on adding a second port jumped out at me. I don't know how I missed it many times before. It looks like I want to do this: (add this to my standard_pinout.hal file) loadrt hal_parport cfg="myport#_0 myport#_1 in" My first port will be defaulted to an output type because I did not specify in. My second port will be an in type because I used in after the port number. Does this look right? Can I start using this port after I have done this?

Re: [Emc-users] 5I20 card type 2!
How are they planning to implement the Ethernet communication? Ethernet is great for things like file transfers between computers-the task it was designed for-but has a some overhead required for reliable real time operations. They might want to consider using ACN-Architecture for Control Networks. The packet structure already includes everything they would need for reliable communication. Here is a link to the ANSI webstore for a description: http://webstore.ansi.org/ansidocstore/product.asp?sku=ANSI+E1%2E17%3A2006 I'm a part of the Working Group that supervised the development of ACN. It was created to address issues just like the ones a servo drive will encounter-timing, reliable communication, variable properties, etc. Javid Butler - Original Message - From: "Kasparov, Aram" <[EMAIL PROTECTED]> To: "Enhanced Machine Controller (EMC)" Sent: Tuesday, January 09, 2007 5:30 AM Subject: [Emc-users] 5I20 card type 2!

Re: [Emc-users] adding 2nd parallel port
Hi Mike Looks like you got it. The test here changes parport.1 to all in except pins 1, 14,16,17. If you are using this configuration inside emc you can see and manipulate the pins using halshow.

We are planning to use PowerLink (with 100bt and POE), But I will definately take a look at ACN. Using PVT (Position,Velocity,Time) packets mean a missing packet now and again is fairly benign, as the interpolater will just, well, interpolate. PowerLink is good for several KHz or so with reasonable number of Axis/I0, and good PVT requires only a KHz or so. PowerLink does require a separate Ethernet for the realtime segment, but has provisions for tunneling TCPIP by dribbling it in free time slots. Peter Wallace - Take Surveys. Earn Cash.

The space works okay here. This is with HEAD, a mobo parport at 0x378, and a PCI parport at 0xc000. Good to know that spaces are not always acceptable. I'll salt that away for when I get a system that fails for some strange reason. Rayh - Take Surveys. Earn Cash.

Re: [Emc-users] adding 2nd parallel port
Steve, Thanks My next step is to create a .hal file (I believe) that makes the connections to hal and halui. I have a couple questions about this. Looking at Anders work, it looks like he has a single file w/ both regular hal and halui connections, that get called from the .ini file using Halfile = XXX.hal. I would like to do the same. I have a decision to make on what features I want to include on my pendant because I only have 13 inputs to work w/. Well I actually have one more unused port that I could use to give me 26 inputs. I will have to come up w/ a clean way of breaking out to 2 individual parallel ports from one pendant to do this. Anyway, I think I have a handle on the normal bit type i/o. For jogging an axis I think I see a couple ways to do it: With out a jog wheel: I could have buttons that would jog in the plus or minus direction. I would have a multi-position switch to select X,Y,Z,A axis. I see in halui that i could use halui.jog. aka axis.minus and halui.jog. aka axis.plus . Because I am limited on inputs I don't want to dedicate a input for each axis + and each axis -. I would like to have a way to use the already selected axis/channel (0-3). It looks like match8 might do this but I am not completely following how it works in Anders .hal file. Also how does halui.jog..plus and minus work. Does it jog continuous when halui.jog..plus is true? I am used to if then else type programming. It looks like some of the available blocks can be used to reproduce this type of structure?

I didn't try it, but it looks like you can select a joint with halui.joint.selected and then jog it with halui.jog.selected.plus and minus. The speed is set with halui.jog-speed. If I was making a pendant I'd sure want a jogwheel instead of plus/minus buttons. It takes the same number of inputs and works much (much!) better. I have a real jogwheel but one of these days I'm going to try one of the little toy knob encoders from mouser etc - they're meant to be volume controls or something, but they might still be more useful for jogging than two buttons.
