Re: [Emc-users] G52 and Fanuc conversion to EMC
Peter, I have a question about the the 7i33. The machine we are discussing has three 25 HP spindle motors operating on 3 separate VFD's. We have a Italian control that was fitted onto a machine and it has a 100ma limit on its analog output. Each VFD requires a minimum of 70ma to run. We had to put a small phoenix contact amp on it to boost the analog signal to run all three drives on that machine. The problem comes when you turn one spindle off and only run on two. The RPM runs higher than it should due the decreased load on the circuit. In other words the analog VREF increases and the two drives have to be retuned. We get around this by putting a blank tool in the spindle and running all 3 wether they are cutting or not. Not only is this a waste of energy it also puts unnecessary wear on the unused spindles bearings. What is the limit of the analog out on the 7i33 channels? I can always use one out per spindle and that would completely solve the issue. What is your take on this? One output or three? Anyone else feel free to jump in!

I have been thinking about trying to develop a product for just this kind of situation. The solution seems simple, and inexpensive. Take an AVR microcontroller and have it monitor the Q-encoder signals. The program would start out counting the time between changes of the signals. When the RPMs get high enough it could switch to counting encoder events for a certain small amount of time. The RPM that is found would be converted to a DC voltage by a PWM signal from one of the counters. The PWM would always be clocked at a few MHz, so the RC filter would have a high corner frequency, and the DC voltage would be able to change faster than most (if not all) servo systems. For older servo motors that top out at about 2500 RPM this should be overkill. Actually theres a better way than changing counting modes at different speeds (from 1/T_Encoder to DeltaN/T_Sample): always timestamp encoder edges, that way, at T_Sample you have both encoder counts (N) and the time it took to get those counts (TsubN) from the timestamps. The velocity can now be calculated as KDeltaN/TsubN. This is what the HostMot2 hardware/driver does to calculate its velocity estimate (glossing over some nastiness that the driver fixes at reversals and stops) Dont know if the AVR has the hardware to do this, We've implemented this on a DSPIC (using DMA) but it wasn't pretty...

Re: [Emc-users] G52 and Fanuc conversion to EMC
That's awesome Mark.Let me give you some more info.. This same program ran on a Selca Control in 16 minutes. That was a $250K refit for a high speed control. That selca is a different animal though. It was designed to push point to point programs thru a 1500 ipm machines. The EMC version is 2.3.0. EMC is well worth the install. I had a quote to install a PC based windows control on this machine (the 3 axis 3 spindle mill) for about $150K from an outside source. Doing it in house and reusing the Fanuc servos we can more than double the efficiency of the machine for about $16K + My labor. We proved it in house with our own programs and hardware. Another benefit is that I know what makes the machine tick as I have been maintaining it for about 13 years. This is where most refitters suffer. No fault of theirs, I just know the old girl a little better. You guys out in the shops need to push this with your higher ups, It took me almost 2 years to convince them to try it and now they are talking multiple installs after watching the control chew up the programs and spit them out. The other PC based windows control is a very good control but it has a price higher that a new Fanuc for just the base control. In this economy you have to pinch pennies and get the most bang for your buck! EMC2 fits that bill perfectly.

[Emc-users] EMCO PC Mill 50 retrofit
A local campus has an EMCO PC Mill 50, which communicates over RS485 with a PC (running Win98, bleh!). I was wondering if anyone here has had any experience with EMCO machines. I'd like to get an idea of how difficult a retrofit with EMC would be. To my eye, it appears that the stepper driver module takes a set of parallel signals - only a scope or probe will show the exact type. Other than the motherboard, there is a PLC that communicates by RS485. If I could get the mill running again (insufficient poking-around time), I could sniff the serial traffic and build a more complete picture of what goes on. My plan is to come up with something where I disrupt as little as possible to make it function, to demonstrate the retrofit. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

It looks for several failed login attempts on any account or TCP port, and puts the source IP address on the hosts.deny list, so they can't access the computer at all through any service. It basically detects hostile botnets and locks them out very quickly. Anyway, I have never had the attackers get past the server/firewall and even attempt to do anything to the other machines in the local net. Since these machines have no WAN address, you have to compromise the server before you can even detect the local machines. I have NEVER seen anything like a true Windows virus on Linux.

Re: [Emc-users] UBUNTU + virus
I agree, I have been hacked into before, but I was NOT behind even a minimal router/firewall, and the system was not locked down. I figure I got what I deserved because I knew better and was just lazy. As far as virus, worm or the like that I am always finding on M$ machines, no, nothing of the like on Linux of any distribution I have used since I started with Linux with the 0.98 kernel. Improper security configuration or lack of proper patching of apps like Apache or mail servers are the largest targets on most systems. Most of the anti-virus that folks sell for Linux or UNIX based systems seems to be more interested in watching for email issues and scanning for windows stuff real time to keep desktop clients from being further infected. All this is not to say that Linux/UNIX systems are immune to hackers, but a virus is not the norm and a bit harder to hack due to the software and system architectures that are built in. I went to a local Linux users group where the sysadmins from a local college presented on their 'super firewall' they have done mainly from open source. It uses VMWare ESX various virtual Linux and BSD boxen to implement. But they have 2 T1, 1 DSL, and 2 cable connections for their entire campus. They provide administration, faculty, and students, including dorms, internet using them, and have various routing rules. They are a small college, but still have 'interesting admin issues' and significant cost issues that dictated their need of a opensource custom solution. Still it was a good presentation. ...

None of these are Open Source, and non work natively with Linux, but since those requirements weren't mentioned in your question, only in the notes you linked to, I'll ignore them in my response. :-) Nobody seems to have mentioned CamBam. It has a bit of a learning curve, but it has a ton of power for it's price. http://www.cambam.info/ At work we use Visual Mill. It's very easy to use if you are coming from a solid model, so it works great with Alibre CAD (which is only $197) or another solid modeler (Rhino, Solidworks, Pro-E). You can also work from DXFs with it, but it loses many of it's benefits if you do. Visual Mill starts at $1k, but it does have a pretty good feature set for the price. http://www.mecsoft.com/ Alibre also offers Alibre CAM, which is based on Visual Mill. Unfortunately, by most accounts Alibre CAM is buggier than the Standalone Visual Mill. Alibre also charges for Maintenance, and I believe Visual Mill does not, so in the end Visual Mill works out to be quite a bit cheaper. http://www.alibre.com/products/ac.asp On Sat, Mar 20, 2010 at 3:04 PM, Karl Schmidt k...@xtronics.com wrote: What are people using to generate tool paths?

Re: [Emc-users] EMCO PC Mill 50 retrofit
Serial is a nogo with realtime in EMC Having said that, depending upon your budget, you could through the existing controller away (and/or ebay it) and pick up a stepper controller that would allow you to run the mill through the parrallel port (cheap) or using an FPGA board (less cheap). for a 4 axis setup, there are DIY kits for under $150, less for 3 axis. The FPGA baords are a bit more but offer a world of other possibilities and they do not need to be assembled. Look in the Linuxcnc wiki and search for supported hardware. It should be very easy to convert these over to modern controls with the existing motors. good luck. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

It might not be just cycle time, but ease of use, the ability to make sure the right part program is loaded and the tool offsets are correct, and the general ease of the whole setup process. But, that sure sounds like a big plus for EMC! Jon Jon, You are correct about this being the result of a lot of things. I did the MDSI retrofit 10 years ago. The machines were MUCH more productive with MDSI Opencnc than they were with the original Cincinatti Big Blue controls. Experience with the retrofit process could be part of it. I personally do not think so. Ease of use would favor MDSI Opencnc. The operators have 10 years experience with it. The setup is done before the production. The operators were talking about the floor to floor production. As time goes by I will be able to determine why there is an increase in production. Machine slide speed is not the reason. I did not try to increase the rapid motion speed. The feed rates would be the same per the program. Using the same fixtures, cutters and programs we get almost twice as many parts per shift with EMC2. I don't know why.

Are you sure we need realtime? I kind of doubt that Emco would use a PLC for anything but the real time operation of the motors.

If it's part of your daily job making parts that look the same. They can be build using the same PRO model. PRO will generate new g-code files without you as a user muddling with creating the tool paths, assigning the correct bits and what not, it's almost on the press of a button... PRO-E can be a pain in the ass sometimes, but so far as a hobbiest I have reasonable good experiences with it.

Since I worked on it, I know that the Gettys servo amps do the same as they did on the old control and no more. I did some block processing tests on a 600 MHz Pentium and had poor results until I was informed of the G64.1 Pxxx option. Then I was blown away by the performance, it was doing over 700 G-code blocks a second. I think the computers in your machines are faster that 600 MHz, so they should do better. But, unless you are contouring complex shapes, I don't think you really need that kind of block processing rate. I only have a few data points. I had an A-B 7320 control (1978-vintage 16-bit minicomputer) and it had a really slow block processing rate of about 4 blocks a second. Of course, it thought it was reading the G-code from paper tape! I've seen a few other controls where you could pretty much read the G-code as it scrolled by. Anyway, I think the only possible variables would be block processing speed, acceleration, or some kind of stalls when changing direction of movement. You can certainly slow EMC to a crawl with G61 on contouring-like moves. Jon -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
