Re: [Emc-users] Interferometric leadscrew measurement/mapping?
A laser interferometer is on my todo list. I've acquired all of the optics on ebay for a total of a few hundred dollars. I've built a power supply. The major part I'm missing is the counting and interpolating electronics with a computer interface. Hi Ken, the heterodyne interferometers I have found described mostly use a two-frequency laser which emits two orthogonal polarizations with slightly (500kHz? or in your case 4 MHz) different frequency. Did you find a Zeeman-stabilized two-frequency laser on ebay? Or are you planning to DIY and put magnets around a normal HeNe tube? Sams Laser FAQ has a description: http://www.repairfaq.org/sam/laserchn.htm#chndzees The other method is to use an acousto-optic modulator to shift the frequency of the light. But the papers I've found use two modulators, and I only have one to spare right now... If I can either find a two-frequency HeNe or DIY with magnets then I'd be interested in testing this, possibly with the m5i20 (already has fpga code for fast encoder counters) for data acquisition.

[Emc-users] needed things (imho)
EMC2 looks interesting. but after fooling with it for a few days on two different boxes it seems to me that there are issues that need to be addressed. Issue One. On both of the boxes I am using there is a common problem. I tell it to shut down and it hangs on the last screen untill i hit the power switch. these two boxes were loaded with two different downloads of EMC2. Both downloads were told to check themselves before being told to load onto the hard drive. the first machine is a four processor intel chip. the second is a 2 processor intel chip. any ideas? Issue two. And to me much bigger. EMC2 basicly supports 6 I/O boards out of the box. Personaly I do not want to spend a thousand bucks buying boards, daughter boards, and softwhere to see if i can control a piece of machinery. If i was doing it to sell comercialy that is one thing. but for what I do in my garage, not so much. what i need is a PCI I/O board with at least 24 and preferibly 48 I/O points that i can wire to a opto isolator (if i think i need it) or directly to a ttl level switch if i think i do not. Why do i want all this? I have been designing machines for almost 40 years. I have been fiddling with EMC2 for a couple of days. Linux? same thing. I want SOME options built in. Like a decent I/O board, maybe some closer error checking.

The power management drivers that let your computer automatically shut off its own power tend to conflict with realtime code. So they are not part of the realtime kernel that we distribute with EMC. Turning off the computer manually is no big deal. Especially since any real machine will probably have other power supplies for things like the motors. On my machine I have a single disconnect switch that turns off all the power. Issue two. And to me much bigger. EMC2 basicly supports 6 I/O boards out of the box.

EMC supports several different I/O boards out of the box. It also supports the standard PC parallel port (or several of them). Buy a few cheap PCI parallel port boards and install them if you need an inexpensive way to get started with simple I/O. The lack of an I/O card that does what you want is not EMC's fault. Hardware costs money, both to design and to manufacture. Hardware companies will only offer products if there is demand and money to be made, and the volunteers who write the EMC software can do nothing about that. If you find a card that gives you the I/O you want, but EMC doesn't support it, you might want to contact the EMC developers, ask nicely, and offer a board with documentation. If the board isn't extremely difficult to program, a driver will probably get written. But the board needs to come first.

You are not tied to the few items listed on the hardware page either, since you are free to write, or hire someone to write, a driver for whatever hardware you would like to use. Why do i want all this? I have been designing machines for almost 40 years. I have been fiddling with EMC2 for a couple of days. Linux? same thing. I want SOME options built in. You have all the options in the world built in already. On a more practical level, you can start experimenting with just a parallel or serial port, then move up to higher I/O count boards, then to boards with FPGAs for high speed functions, and also to analog servo ocontrol boards. I'm not sure quite what you mean by having some options built in if that doesn't cover it. Like a decent I/O board, maybe some closer error checking. Closer than what? Error tolerances are set up by the user. You can have a machine that will throw a following error if it's one micron out of position. EMC2 is the only low (or no) cost system that actually closes the servo loop with the motion controller. Other inexpensive systems that support feedback can only use it as a traveling limit switch for detecting following errors, they don't use the feedback to alter the motor commands.

Network errors? It's pretty uncommon for updates to fail on Linux these days. You don't mention what you mean by choked either. Did you run out of disk space? Did the downloads fail? Was some package unable to be updated for some reason? You can click the details button and see what happened - it opens up the hidden terminal where all the package updating actually happens. Sometimes, there will be the need to hit enter or something in this terminal, which may not be shown in the dialog box. - Steve -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

The fact that EMC2 gets a dramatic response from just about everyone who tries it speaks volumes to its universal worth! Probing the what if buttons.

The futurelec, at $80 AUD. is only a small fraction (maybe 10%) of either of those. And its off the shelf. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Re: [Emc-users] Estop Input
Ian Eagland pisze: Hi New to both EMC and Linux. Set up my mill using stepper config wizard and the axes and limits work perfectly. I have Pin 10 set to Estop In. However EMC runs with pin 10 high or low. Do I have to set up Estop somewhere else? I am guessing I have missed something.

I have been designing machines for almost 40 years. Combine that with the expertise you can find here and in weeks or months depending on your learning curve negotiating the new OS environment and you will be pleasantly surprised. Hang in there. We are all after the same goal in one way or another. -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
