[Emc-users] 7i43 setup woes
I've run into a snag getting my 7i43-P talking to my EMC machine.. This is a new setup, so I assume I've got some stupid configuration issue. Any assistance would be appreciated.. I've got a AT5NM10-I set up with LiveCD install with an on board parallel port attached to a 7i43-P. It's the 200K model. Rev C. the parport modules are blacklisted in an attempt to isolate my problem. The 7i43 is powered by an external power supply (+5V) in P1. P2 is connected to a IDC ribbon cable <-> DB25F <->DB25M to M adaptor <-> PC. The whole assembly is about 4 inches long. As far as I can tell, the ribbon cable assembly rings out true. P3/P4 have nothing connected yet. I've got a couple 7i40s to connect once I get over this hump. Powering everything up, (in EPP mode) all three lights come on. I load hostmot2 and then attempt a firmware load. The INIT light goes out and I get an "invalid module" parameters error. dmesg indicates that the driver thinks I've got a 400K board (I think this is actually the driver reading FFs instead of a 0 or 1). I haven't determined if the data displayed by debug_epp is actually what's the bus or not. I hooked up an O-Scope in an attempt to determine what was going across the port, but need to spend some time looking at the source code to make heads or tails of it. I thought someone here might have a shorter path. If I set the board to load from EEPROM, the lights flash on and then INIT and DONE go out. I'm not sure what's on the EEPROM and haven't done enough research to determine what to transmit to test the board in this state. Also, I attempted to use the DOS utilities (under WinXP) from mesa for the 7i43. Those didn't work either, but the cable assembly was common between my two setups & the Parallel port was on a laptop docking station. I got the same results as if I gave it a bad port address (all 0xFFs); so I take those results with a grain of salt.

Re: [Emc-users] Avago HCTL-2032
Hello Kirk, last week, I made a little circuit board using the HCTL 2032 and an ATMega 32 for a DRO unit (4 axis). It has not been tested yet. I am not using the index track of the encoders. But, as far as I understand the technical data sheet, the index pulse is not available as an output. It can only be used to reset the X and Y axis counters after one turn of the encoder. This makes it useful as an angle indicator. If you want to use the index pulse externally, it would be easy to attach a CMOS or TTL chip to bypass the HCTL 2032 and obtain the angle information without resetting the XY counters.

In my case the bearing arrangement for the worm was rather less well engineered than I liked to use for a motorised axis (especially the thrust arrangement, which depended too much on carefully tightened grub screws) I ended up making a new inner housing for the worm, with an inboard needle roller near the worm, then an outboard pair of angular contact bearings. I then connected the servo with a rubber finger type coupling to fully isolate the motor bearings. (If your worm is properly straight this might prove to be less of an issue….) In your case I would probably investigate using a toothed belt drive to bring the servo alongside the table rather than sticking out a large distance as that would probably be limiting in the case of a 5th axis. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" -- Forrester recently released a report on the Return on Investment (ROI) of Google Apps.

You would also need to connect the enable signals to the breakout board in your .hal file. There should be some lines similar to this: "... # connect enable signals for step generators net Xen axis.0.amp-enable-out => stepgen.0.enable parport.0.pin-01-out net Yen axis.1.amp-enable-out => stepgen.1.enable parport.0.pin-06-out net Zen axis.2.amp-enable-out => stepgen.2.enable parport.0.pin-16-out # connect signals to step pulse generator outputs net XphaseA stepgen.0.phase-A => parport.0.pin-02-out ... " Your lines with parport.N.pin-XX-out will need to match the pins on your breakout board. The enables go ON when the machine on button is pressed to ON. This can help keep your axes from moving until it is safe, but in order to do this properly you need to have a charge-pump watchdog to keep the enables off while the PC is booting. Or, as you found out, you could do without the enables and leave the drivers active all of the time.

It made me think that was a normal thing to do, then have EMC2 keep tally of the index count and the between index count to derive the overall position.

For those that haven't done it. It is quite easy 1)Get your cable which is often 50pins wide. It often has a red stripe down on side to help identify pin 1. If you use a part of the cable that doesn't have the red on it, you can always add it with a sharpie. http://bgp.nu/~tom/pub/ribbon/IMG_2527.jpg 2) Cut it to length.

Re: [Emc-users] Avago HCTL-2032
emc can use the encoder index-enable feature in two ways: at the beginning of spindle-synchronized motion, and at a specific step of homing. Specific machines might use index-enable in other ways as well. For instance, I know of rotary toolchangers with quadrature output and index. A ladder program would probably use the index feature once at the first toolchange to establish the absolute position of the toolchanger, and from then on use the position of the toolchanger's encoder to know what pocket is currently prepared.

Index handling has to be done in the same place as the counting, so if the counting is taking place in some chip, the index handling has to be in there too. the hal interface to encoders with index is (there may be a better explanation somewhere in the docs): when index-enable is high, and a rising edge of index is encountered, (and the optional index mask is false), the count is reset to 0 and index-enable is set to false In terms of our smart hardware interfaces, there are a number of ways to do it, but they all boil down to the requirement that you can tell inside the PC that in a particular servo cycle. This is: * an index occurred since the last servo cycle * EITHER the number of counts since index * OR the total number of counts since power-on AND the number of counts latched when the index was seen (from which you calculate counts-since-index by subtraction) Without an "index happened" indicator, you can't even be sure from the counts alone that index happened. If you just went through index in the positive-going direction and reset, then you go through it in the negative direction, the second reset will happen just when the counts would naturally have been 0 anyway! Without an "index happened" indicator that is latched exactly the same as the counts, you can't be sure whether the counts you read now were affected by the "index happened" register that you read just a moment later (because the index could have arrived between the reads). It's important that index handling be exact to the encoder edge instead of exact to the servo cycle so that it is actually effective at giving a high resolution snapshot of position or angle. For example if you are only checking index at a 1ms (servo cycle) resolution, that makes 1600rpm threading vary its start angle by 9.6 degrees. If you use homing with index, your encoder is turning at 3600rpm, and your leadscrew is 5mm/revolution it introduces .3mm of uncertainty in your homing.

[Emc-users] gladevcp changes
For those folks which are playing with, or helping document gladevcp: yesterday another set of changes relating to gladevcp was merged into master, and for the time being we consider it feature-complete (bug-complete ;-?). Creativity on our behalf will most likely turn towards new or improved HAL widgets; the programming interface is considered stable. Important changes: - a gladevcp panel may also run in Axis' place for PyVCP, not just a tab - see GLADEVCP option for the inifile - all gladevcp-related HAL commands may now be collected in a single POSTGUI_HALFILE - it's not necessary anymore to pass one halcmd file per gladevcp tab/panel since one may assure now that POSTGUI_HALFILE is run only after all HAL components are ready - the wiki documentation is now in sync with the code in master, as are the examples under configs/gladevcp - the API suffered a slight change (actually a simplification) - see configs/gladevcp/README.changes. - Pavel fixed key forwarding - most importantly, an Escape key will program-abort Axis even if focus is in a gladevcp widget - gladevcp now sports a man page please let us know if you find errors or unclear/missing documentation. -Michael ps: as of now, there is still a missing package dependency in master - if you are working off master, please do the following (I assume this will be resolved shortly): sudo apt-get install python-configobj -- Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] Varispeed transmission and VFD, meaning of S code?
I used the encoder for speed feedback on my lathe. The program doesn't have any idea what speed the gearbox is but it figures it out and runs at the correct speed the best it can. I use HAL components to digital filter it, it takes a couple seconds to get to the correct speed but it works pretty good. The worst thing is when threading EMC2 zero's the encoder making it look like a huge speed error. I used HAL components to limit the rate of change to things that are possible, going many revolutions in reverse in a millisecond or so isn't possible. My feedback would work better if it would just skip the feedback when the encoder count gets zeroed. Perhaps hal components could adjust your vari-drive and VFD?

In that case, I would be tempted to hide the complexity from the operator (even if it is you) and make it all automatic. I think I would be tempted to always have a target VFD frequency of 60Hz (which is where the motor will be happiest), and to set the varispeed on that basis. You could then add a closed-loop spindle control on VFD frequency only. That means that the varispeed will go to an open-loop position on the basis of the S command, then EMC2 and a closed loop will fiddle the motor frequency for load adaptation, and for speeds above and below the range supported by the Varispeed. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" -- Lotusphere 2011 Register now for Lotusphere 2011 and learn how to connect the dots, take your collaborative environment to the next level, and enter the era of Social Business. http://p.sf.net/sfu/lotusphere-d2d ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

I have the best of both worlds on my machine, both an MPG for the incrementals and a joypad for blasting from one end of the axis to the other.
