I don't recall whether the latest thing I have run is v2.2.2 or v2.2.3, but I just downloaded the latest version a couple of weeks back, and it was working then. I will try it tonight and make sure it is working. I also know that Chris is about to release a new version, but I have not seen that it has actually been released yet. I need to add some online documentation for that utility, it is still mainly within the c source files. Regards, Eric Awhile back, EMC2 v2.1.1, I was successful in commanding EMC2 from a terminal window using commands such as 'telnet localhost 5007' and 'axis-remote'. 'Telnet' opens a variety of commands to EMC2 (through emcrsh) and 'axis-remote' allows shutdown (and a just few others). Now, with v2.2.3, telnet is not working. Here is what I get (I first start 'emc' in another terminal): ~$ telnet localhost 5007 Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused ~$ I have searched wiki and linuxcnc for 'telnet' and 'emcrsh', but to no avail. Also, I thought, AXIS communicates with EMC2 via telnet? Any help is appreciated. - This SF.net email is sponsored by: Microsoft Defy all challenges.

At 01:15 PM 3/11/2008, you wrote: This most certainly is not an EMC problem, but a network setup problem. Chances are you don't have telnet server running on the EMC machine. Telnet is a pretty deprecated service, and may not be enabled by default anymore. Can you use ssh? ssh is served by the sshd daemon, I forget what the name of the telnet daemon is (inetd, xinetd ?) telnet is also wide open to the network, passing user names and passwords in the clear. ssh is a much better application, as is sftp for transferring files. Both encrypt the user name and password. That being said, on some machines, the telnet deamon is in.telnetd and on others it's just telnetd. The telnet deamon runs under either inetd or xinetd If it's xinetd, got to /etc/xinetd.d, vi the telnet startup file and set disable = no. If it's running under inetd, vi the /etc/inetd.conf file and delete the comment in front of the in.telnetd line. In either case, you have to restart inetd/xinetd by typing pkill -HUP inet on the command line. Depending on which account you are doing this from, you may have to use sudo in front of all these commands. On the EMC machine, type : telnet localhost If you get the same refused message, the machine is not serving telnet requests, and you'll have to enable the server. I don't know enough about the way you set up your system to advise further. Jon Mark - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Emc-users] Can EMC2 support any 'AC Servo Motor'?
Dear All, I am a student. I will use a open platform system to control three axis AC Servo motors in my final year project(FYP). I searched a EMC2 in the internet. It is base of the linux OS, it supports maximum 9 axis (very powerful), GM code and graphics mode. It is very suitable for me to do my FYP. I have questions to ask all people: 1. I must use AC Servo motors to do my project and I choose SANMOTION R of SANYO DENKI INC. Below is the user manual: http://www.sanyo-denki.com/Data/Servo/catalogs/R_Ver3.pdf In page 42(3-10), the pin 21 is the input control command which is using speed and torque value. But I found in the HAL Handbook that it only support ‘step pulse’ to do the control. Is it menu that the EMC2 cannot support any AC servo motors?? Are there any people can help me or give me any suggestions how to solve my problem? Thank you very much!!

Re: [Emc-users] Can EMC2 support any 'AC Servo Motor'?
WE Chan, The amplifier shown on Page 12 can be used in Speed mode on CN1 pins 21 and 20 (not STEP or PULSE ) EMC2 would command the motion by an additional card ( Mesa 5i20 and 7133 for example) that would generate analog voltages to your amplifier. The 5i20 would actually generate PWM, the 7i33 would translate/integrate the PWM into analog. Your motor would pass the encoder information back to the 7133 and then to EMC2 to close the position loop. regards TomP - This SF.net email is sponsored by: Microsoft Defy all challenges.

Hi RobI've been curious about these dual drive axes for quite a while now. There are several possible mechanical lashups with something like this.

Re: [Emc-users] Can EMC2 support any 'AC Servo Motor'?
Hi Howard Glad to hear of your interest in EMC2. It is a great system for students because it will allow you to experiment with most motion control variables. The pdf at the link you posted includes a lot of sales pitch. It appears to have been written and edited by someone with limited motion control experience. They have very successfully blended together at least three input signal types to maximize the apparent value of their products. You will need to sort out most all of it to get the system that will work for you. Sanyo lists three kinds of motion signals. They include analog voltage, step and direction, and CANopen. EMC2 as it exists right now can handle two of these, analog voltage, and step and direction. We do NOT have serial drivers in our motion software that would permit CANopen control. Hint -- Serial communication using CANopen would be an excellent graduate student project. I'll expand just a bit on the two systems we do have for your use right now. It looks like Step and Direction signals can be used with both the stand alone amps and with the multi axis package. EMC2 produces millions of step and direction signals every day. They are the preferred motion signal for stepper motor powered systems. What this drive does is make the servo motor look like a stepper motor if you use this control signal. You will have a real advantage over steppers because the motor's torque will not fall off as speed increases but you will still see some cogging at low speeds. There may also be an upper RPM limit, well below the max speed of the motors unless the drive includes a pulse multiplier or you add an external hardware work around. Permit me to do a bit of computation on this max rotational velocity using step signals. If the supplied encoder is 2500 pulses per rev, and the amp equates external steps one-to-one then you will need 2500 pulses for each revolution. Let's imagine that your computer can supply 30k pulses per second (PPS) using the EMC2. That combination will allow 12 revolutions per second or 720 RPM. What is the maximum pulse speed you can expect from EMC2. Alex and I were is a bit of a contest a while back and were able to get pulse speeds of 75 to 90 thousand pulses per second. It may be that we could get even faster speeds now that Jeff has added his rate doubler. You can see that rotational speed is still somewhat limited. At 90k PPS you would be limited to about 2100 RPM. The second type of speed signal that EMC2 can offer is an analog signal. This could be pulse width or -10 tp +10 volt using a PC card like Alex and Tom suggested. These analog signals have the advantage of driving the motor to full speed and to constant velocity at low speeds. Analog has the advantage of producing a real, closed loop servo system. I would use this system even though it costs the price of an extra computer board and requires a bit more care in wiring. If you choose analog signals you must make certain the amps you purchase allow you to connect those signals. Not all of the amps listed do that. It looks like, although the pdf does not say so, that you will need to use a Microsoft OS to tune the amps. Writing a Linux/EMC2 based tuning software for these drives would also be a valuable student project, if your school and discipline includes both hardware and code writing. Good luck and welcome.

Re: [Emc-users] Homing using 2 motors per axis
I had a similar problem. I solved it by using a toothed timing belt between each screw, such that both sides were forced to stay in alignment. That way, I didn't need to worry about misalignment during either homing or actual milling. I only used one homing switch for the axis this way. It seems to work fine. If anyone sees a problem with this solution, I'd like to know about it so I can take preventive measures. I recently finished my machine, so I don't have a lot of experience with it yet. But, so far, it's working fine! Dennis - This SF.net email is sponsored by: Microsoft Defy all challenges.

I dont feel comfortable with saying go with this or that company but I have seen some beautiful work on aluminum, even polishing can be done. corn cobb medium and a polishing compound added in can do a fine job. medium types include the plastics, ceramics, gravel, sand, crushed seed shells, custom metal forms, ball bearings. each of them having a specific application. When your talking burrs, you can end up cutting material away from all of the part or something to the extent of deforming the burrs. the little table top from harbor freight, is really handy and may prove to be worth your while. if you plan on using something like that with more abrasive compounds for burr removal I would recommend you line the plastic bucket with that plasti-dip stuff, something that will stick to the bowl and provide some added thickness, and then experiment with things around the house or search the web for vibratory medium.

I dont feel comfortable with saying go with this or that company but I have seen some beautiful work on aluminum, even polishing can be done. corn cobb medium and a polishing compound added in can do a fine job. medium types include the plastics, ceramics, gravel, sand, crushed seed shells, custom metal forms, ball bearings. each of them having a specific application. When your talking burrs, you can end up cutting material away from all of the part or something to the extent of deforming the burrs. the little table top from harbor freight, is really handy and may prove to be worth your while. if you plan on using something like that with more abrasive compounds for burr removal I would recommend you line the plastic bucket with that plasti-dip stuff, something that will stick to the bowl and provide some added thickness, and then experiment with things around the house or search the web for vibratory medium. Im in no way associated with this company but with a quick search on google, this link came up. http://shorinternational.com/TumblingMedia.htm that should give you an example of the various mediums and what they are capable of, Now the trick is to find a way to get EMC to control the thing :) coolant/water injector timing, you know fun stuff :) I hope this was of some value to you, I typically do not post to the list.

Re: [Emc-users] vibratory polishing/deburring
That's the one I have and it does fine, but as Phil said you need to match the cutting medium to the work. Phil's suggestion to line the bowl is a good one, too. I'm not using an agressive cutting material, but I can see where the bowl would wear out quickly with something that was agressive.

That adds some credibility. I was afraid to pick one up, and then sit there all day, only to find nothing changing on the parts. I'm going to snag this one: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93252 It's $10 less than my 1/8 dovetail bit, and much larger, and more useful! Thanks for the info, Gary I've used some from Harbor Freight. They are typical HF quality, but fine for light use and fairly quiet. I've got a relative who owns a CNC machine shop that uses them as well. And they are cheap.

Thanks! -Gary I have the Lyman version, and have used it on steel, but the media abrasiveness I have, the red or green stuff, needs help for steel, 2 days didn't cut the hot roll scale off, just polished the edges a bit. It might be just the ticket for alu parts though. If it wasn't for the weight of river sand spoiling the jiggle, it might work pretty decent on steel but I've not actually tried it myself. I also have to run it outside as the hum pretty well permeates the house when its sitting on a rug on the cement floor of the basement. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
