[Emc-users] FW: Classicladder counter
From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: RE: [Emc-users] Classicladder counter Date: Wed, 30 Jul 2008 06:22:22 + Hi Terry If you use use variable %C0.V in a compare block It will tell you what the current number is in the counter. eg.-[%C0.V=4}--(Q1) You can also set the value of the counter using the same variable in an equate block. eg. |B1|-[%C0.V=4] You can export the counter number to a HAL component by using an equate block to assign it to a S32out word variable. But you have to set up the realtime module to create S32 in and out pins . ( I don"t think this was what you were asking though If it is then I will tell you how if you need) If you want to reset the counter to zero then the reset pin is the way to go otherwise to set to another number (say 1) then use preset and assign 1 to the preset property.

Re: [Emc-users] Conversational Programming for EMC2?
This looks like a CAM package for Linux.I would guess it posts out G-code? Looks promising. They shouldnt call it conversational. Much like the stepper vs servo debate there is the same a conversational vs G-code in the world of CNC machinists. Conversational was made to sell machines to owners of machine shops with the sales pitch of "anyone can program this control"They think cheap labor, get rid of all those G-code guys.When the cheap labor proves that machining is more than writing programs by ruining parts and tooling,us G-code guys have to make those conversational machines run. I am a G-code bigot.Does it show? Your subject line sent chills up my spine. Conversational is for girls.

[Emc-users] Classicladder
Hi, I have a tool changer that needs to be homed each day(at least it did with the origional control),because it has no encoder--it counts revolutions on the gear motor that is driving the magazine,one rev of the motor is one tool station advanced.There will be a counter in classic that would watch this gear motor switch. There is a prox switch for homing the magazine This is my plan for the homing: A push button switch that the operator would hold down (or a timer to keep it going after momentary closing) for at least one rev of the magazine,prox switch gets made at some point on this one revolution. Would the rung that reads the home prox switch go like: a NO contact(home switch input) on the left side and this will go to the R (reset?) input on the counter block? This input needs to reset the counter I looked through the examples in the download of classicladder on the sourceforge and there was no examples of the counter being used that I saw and the switch on the gear motor doing the counting: NO contact on the left and this hooks to the U(up counting) input on the counter ? Is the value of the counter usable in a compare block?

Re: [Emc-users] Steppers vs Servo based CNC kit for Sherline
I have my reasoning and 2 main factors lead me to decision you may not like. I'm going to go with steppers. Main reason is cost. Second main reason is that I want to start making parts quickly, and don't want to spend a lot of time on building CNC system itself. 2 main obstacles beside cost for DIY CNC are lack of knowledge of electronics and virtually no tools and skills for producing other required mechanical bits. After all, CNC supposed to be the way to produce parts for my projects, not another project by itself. Beside this all there are other learning curves in front of me - CNC programming, CAM systems and CAD to CAM conversion. DIY CNC would add a lot of learning to already big pile I have in front of me. PS: Support from the group in my case was basically reassurance that steppers would do just fine for my needs.

Well, If it's not playing sound it's not using much resources, however there are like 18 sound modules alsa, oss, mixer, snd, pcspeaker, etc. Even churning through all that stuff if they are not being used seems like a waste of precious cpu cycles. I downloaded rcconf, and used it to knock out cupsys, a Hewlett Packard specific print module, bluetoolz (sp?), and festival (text to speech).

But just think how cool that would be to have some really large speakers and launch the "Top Gun" theme "Danger Zone" as you start milling a chunk of metal! Dim the lights in the room and turn on spot lights to the center of the action (Just a few more bits in a parallel port!). Might sell a few more CNC milling machines if you had that kind of video!

In other words, what do you have currently in hand that you could use to get closer to your goal? If you have an old printer or piece of surplus equipment with adequate motors, start with that. With this you should have a power supply, motor driver, motor, sensors, wire, etc. It shouldn't matter if the motor is a stepper or servo. I have a pile of surplus I dig into regularly to test ideas that come to mind. I think getting EMC to control bits of a surplus printer would be a good project that should cost nearly nothing.

AXIS needs an environment variable to be set so it doesn't attempt to export HAL pins - HAL isn't networkable at the moment (at least not in RT - I think someone did make an ethernet HAL transport, but I don't remember the specifics). It's theoretically possible to run the IO controllers (spindle, lube, coolant ...) on a separate PC as well, since IO control is done with NML messages. NML can go over a network just as well as it can travel via a shared memory buffer, albeit slower. From what I've seen, networking causes RT blips in the 10 microsecond range. This should vary based on hardware, so YMWV. Disk access (on ext3) causes some issues. I didn't see a lot of change when I got rid of all the other stuff that runs on a normal Ubuntu system, other than going to a non-graphical boot. The experimentation I did was on a dual-core system, using a SMP RT kernel with isolcpus=1, so the RT code all ran on a separate core from the rest of the system. - Steve - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

IMHO, to a certain extent using the Estop as a stop is a good thing. It helps build in an instinct to hit Estop as soon as anything starts going wrong, rather than wasting a couple of seconds deciding if the problem is basd enough to warrant hitting Estop.
