Re: [Emc-users] Users Locations
Hi Steve, I got them, but there is also the concearn other people are having (having public viewable address data). I understand some have no problems with having their address up, some do. I chose (for now, and it's up for debate) to have the users beeing visible only to registered visitors. On the other hand, people concearned about revealing info about themselves are not forced to enter any data they don't like. Entering only the city, area, country should be enough to put a pin on the map. Regards, Alex Perhaps the intent of my remarks were misunderstood, or at least buried by others concerns. My point was that a casual visitor to the web site would have no idea that the map or forums even existed. For me at least, it is not possible to see any of the above without registering and logging into the system.

[Emc-users] double bipod kinematc: Jog axis U, V not working
hi all, I have now implemented my double bipod kinematic, based on the example of the Integrator Manual. I use axis X,Y for 1st bipod and U,V for 2nd bipod. Seems to work fine generally, but 2 issues with AXIS GUI: In world view I cannot jog axis U, V. Axis X,Y jogs perfect. Jogging in joints view is also working. Axis are homed and I can move all axis in MDI with G1, G0. Is there a known bug ? In joints view, the radio buttons to select a joint are designated with 0-1-2, 3-4-5, U-V-W. This is probably only a visual effect. Position display has the right designators (0-8). I use the latest version of EMC2, installed with installation script on top of Ubuntu Hardy, installed a week ago. regards Verschicken Sie SMS direkt vom Postfach aus - in alle deutschen und viele ausländische Netze zum gleichen Preis! https://produkte.web.de/webde_sms/sms -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

I sure did mean SCR and Triac-type SSRs, the ones marked for AC output. I was looking at two devices, both datasheets looked the same to me except: S108T02 has Zero crossing functionary (VOX : MAX. 35V) S108T01 has Non-zero crossing functionary I just want to turn a 24 VAC transformer on and off for my weathercam antenna rotor, so I suspect either one will work. Actually, zero-crossing SCRs are not real good for this. With little transformers with high winding resistance, such as in this case, either will work fine. With bigger power transformers, turning on at the zero crossing causes the transformer to be saturated every time it turns on, with a big HUMMMmm. A random-turn-on SSR will only do that when it happens to be turned on near the zero crossing. Best is a 90 degree turn-on, where it turns on at the voltage peak. I haven't seen that they sell such a device, but a PLC could do it for you. Jon Doggone it, I learn something new all the time reading this list and others like it. I've been using SSR's as the switch between PID temp controllers and heating elements in convection ovens that I make for the bamboo fly rod makers. I always thought an SSR was an SSR was an SSR.

I also no that anyone who is lukewarm to any subject will not likely succeced. The home manufactureing buisness unlike in the past can manufacture in short run quantities much cheaper than the big shops. And they can do it more convienent to their customers. The home shop if he is not incorporated and does not have to pay taxes on parts he has made and are keeping in stock. If he is making spare parts for a brewery he can keep a months supply in stock and run his wife by the customers maintenance department on the way to the grocery store and make a delivery. With free software and thousands of dollars of free advice from online lists to set up and run new machines. Getting started is cheap, cheap,cheap. Machinery is cheap and software is free and very versital. Robots to put and take parts are cheap or easy to build. In 1967 I bought a Southbend lathe and ran it at home When I stopped to go bid on some work the machine stopped and I was not making a cent. So I expanded. I bought a building and hired machinists costs went up. I would be willing to bet that today I would not even concider expanding. My wife would put stock in a mill or I would while she or I took a laptop and programed the part in the buyers office and give him an almost foolproof price right then and there while at the same time work goes on. It used to be that a small shop could not run 10,000 parts so he could not meet the price of a large manufacturer today the home shop can make them for the same price on 200 pieces. The home shop can forget about profit, a man and his wife can make $100,000 a year and never leave home. All he has to concider is, are they making a good living? It has always been that people thought they had to make wages plus a profit. Thats true if you have hired someone else to work for you. If you and your wife make no more than wages in a factory rember you are not wearing out a car for you and your wife, you are not paying a baby sitter. Your children are getting an education in running a buisness. I sat and watched my 9 year old great grand son program a part on his own personal laptop the other day. Amazing!! How do you think he will make out in life? Even if he doesn't go to college, though I'm sure he will, he will still do well. Someone commented that the potential is there to do this. I would say if the potential is there, it will happen. I live in a college town and last night talked to the Dean who is a near by neighbor about night classes to teach this subject. We talked to after midnight and she is very interested. Maybe they will try it one year and see if there is enough interest to continue.

[Emc-users] EMC2 typed versus scripted commands
I am trying to use a Mesa Electronics' m7i43 FPGA card, one of their 4 servo accessory cards, and their input/output card.

For me, in such an endeavor, I realize I have a lot to learn, so I started out just try to pull the Estop relay to ground. I found the correct set of functions to do this (setp hm2_7i43.0.gpio.P3.041.is_output 1 , setp hm2_7i43.0.gpio.P3.041.is_inverted 1, setp hm2_7i43.0.gpio.P3.041.out 1). Then I confidently added them as 3 lines of code to the .hal file. I then stopped the EMC code (using the upper right hand X) and restarted it by clickong on the icon on my desktop. I was really suprised when the I/O didn't work. I tried re-tying the commands in as I had before, and that didn't work, either. Then I tried every combination of instruction I could, and only occasionally could get the relay to be pulled to ground. The 3 instructions and a change in the number of PWMs coming put of the FPGA are the only changes I made to Ted's files. Well, I seem to remember now that some components of EMC remain when you kill the program as I had. So I shut the computer completely down, started it back up, and tried the new hal script. The changes in the script didn't seem to do anything. I could type in the changes, and then they would work. Fearing I was trying to ask EMC to do something it was not ready to do, I added a call to a separate file at the bottom the the ini file, and loaded the commands in the new file.

That is a horribly complex piece of code and it's possible the error may be associated with the math involved. But, It woks FINE for me! I thought YOU said One interesting quirk I did see was that the finish end of the thread was compressed to a higher TPI. Yes, that's right. I thought it was a minor quirk, and due to the complexity of the threading.ngc code, I didn't take the time to really figure out how the lead-out was being done. This might be something that the recent improvements in EMC take care of. What version of EMC are you using? 2.3.0 beta2 I've not seen any compression in pitch, or any other problem for that matter, and I've been deliberately trying to break it to see how robust EMC's threading is. The only thing I've not done yet is trying to thread with a faster spindle speed/higher pitch combination than the max Z velocity can handle. I would expect some sort of error message and a stop. That's the funny thing, this thread is definitely not beyond the Z axis max feed rate, as the good part of the thread proves. So, it has to be the slow-down at the end of the thread. I have to look at how this is coded to see how much distance it is allowing for the Z motion to stop at the end. I think it pulls the tool back at a 45 degree angle, but if it was hard-coded for a fine thread, then it may not be allowing enough distance for the Z to decelerate as the X pulls back. As I say, I haven't really deciphered the code. My real concern is Mr. Harris' problem with the encoder counter sometimes missing the reset on index, while it sets the bit saying that it has done so. An earlier version of the firmware/driver had this problem, but I made the final fix at the 2007 EMC-Fest, and the driver fixes were in the July 2007 release of EMC2. So, I wanted to see if anyone else was seeing similar problems. Also, I don't see why the spindle sync would care what thread pitch he is cutting! That makes no sense to me at all.

Thats what needs to be commented out to disable the watchdog This is unfortunately not true. There is currently no way to disable the watchdog via the hostmot2 driver, so it's always on and biting people who dont pet it. Sorry! Compounding this problem, in the sample hostmot2 config distributed with 2.2.8 the watchdog stuff is commented out, which means it always bites right away. I dont understand how this ever works for you. Maybe i'm missing something here. The easiest fix might be to upgrade to 2.3.0 beta2, which has a hostmot2 7i43 config that doesnt bite people.

There is currently no way to disable the watchdog via the hostmot2 driver, so it's always on and biting people who dont pet it. Sorry! I was just going on my understanding of the hardware, if the timeout register is not written, it will never bite (I guess the driver writes it with something even if no timeout init is done) Compounding this problem, in the sample hostmot2 config distributed with 2.2.8 the watchdog stuff is commented out, which means it always bites right away.
