The parts are 8"x6"x3" Al boxes made from square tube with a few slots and holes CNC'd in so the surfaces are still the raw surfaces. I can CNC the boxes with a flat-face-mill , but wonder if there isnt something else you know of that is maybe a bit faster as I need to clamp and turn each side for the mill if I want to do it that way. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ admin-W4ay7r7vdIs< at >public.gmane.org 2008-12-03T03:51:09 http://comments.gmane.org/gmane.linux.distributions.emc.user/11009 I am using the Mesa 5i20 & 7i33 DAC board combination to retrofit a Kasuga mill. I am controlling the spindle thru a VFD that takes the standard 0-10V speed reference plus start and reverse. I am currently working on the problem of outputting a speed command /voltage signal that does not switch to a negative integer/value when I hit m4. The command: m3s3000, for example works fine without the abs component loaded, but M4 will turn the integer output from motion.spindle-speed-out to a negative value, which my vfd won't respond to. I am trying to use the abs component to strip the negative value from the floating point speed command integer coming out of motion.spindle-speed-out. Below are the corresponding statements from my m5i20_io.hal file: # Set up spindle speed control loadrt abs count=1 net spindle-rpm-cmd motion.spindle-speed-out linkps abs.0.in <= spindle-rpm-cmd newsig abs-spindle float linkps abs.0.out => abs-spindle linksp abs-spindle => m5i20.0.dac-03-value net SpindleOn motion.spindle-on linksp SpindleOn => m5i20.0.dac-03-enable setp m5i20.0.dac-03-gain [SPINDLE]DAC_SCALE #from 5i20ini file# setp m5i20.0.dac-03-offset 80 Looking at the Halmeter pins/signals, the abs component shows up with 3 pins but integer values that appear on the abs.0.in pin never come out on the abs.0.out pin. Zip, nada, no output from abs. Is there a parameter or argument that I am not aware of to make it function properly? Is there something I am missing here? Thanks everyone for considering this.

Is this intentional? Basically I wrote my code covering several files and labeled them stp0.xxxx stp1.xxxx etc. With stp0.xxxx use to pre-position the table for touch off. Is my modus operandi flawed? Are we not supposed to manually execute g-codes in the middle of an executing program? Thanks.

I see that by default the kernel is compiled to only support one processor but what would happen if SMP support was compiled in? Would RTAI choke? As multi-core processors become more prevalent, would it be practical to dedicate one core to the realtime stuff and let the other(s) do the rest? It seems wasteful but I would have thought it would give very low latency.

On disadvantage of them is that the used cutters are hand-placed & thus vary in length. Now I was wondering - is there any chance of using the gcode for probing and dynamic tool length compensation to enter a calibration-routine after the tool has been switched? We would of course need a "inverted touch probe" thingy - e.g. capacitive sensor plate, or something like that - to move the cutter to & get feedback over the tool length. This most probably would also involve using two coordinate systems, on for the piece and one for the length probing. Any suggestions?

When EMC is launched, it works, and the motors turn fine the most of time, but sometimes the port is erraticaly activated. It seems that a "phantom" software works together with emc. I have installed ubuntu 8, this problem doesn't appear, but my video card is not well recognized (problem when emc is launched) So : ubuntu 6 : video OK, parallel port erratic ubuntu 8 : video nok, parallel port ok. My PC (celeron 466) works fine with win98 ;-) Do you have an idea ?

The more things controlled the better the understanding. EMC2 is so versatile it can control and 'enhance' almost any project. The more people using it the less geeky (if that is a word) it is. I think that is a good thing. The more people using it the more development, development ideas and applications we will have. Just my opinion. thanks Stuart ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ Stuart Stevenson 2008-11-27T05:36:46 http://comments.gmane.org/gmane.linux.distributions.emc.user/10848 Hello, Am interested in using EMC2 to control some traditional antenna rotators, like the Alliance U-100. These are AC motors that are turned on/off and reversed using relays (have known these to be called "bang-bang" controllers). I would like to use a triac and encoder feedback to control these in EMC, maybe, using PWM. Anyone done this type of control in EMC, or have some pointers, or both? Thanks to the developers of EMC! And, thanks for any information offered.

The longer I let the latency test run, the more likely are the latency numbers to show up any undesirable behavior. In some cases, a cpu/motherboard-combo that looked great after the "at least 15 minutes" suggested on the Wiki started looking shabby after a hour or so even when not being hammered by glxgears, etc. Hence this modest suggestion: when reporting latency numbers to this list or to the list on the Wiki, please note how long you let the test run. Thanks in advance. Regards, Kent *trees grow rings, I accumulate computers.

I set up all the parameters needed to drive an axis including backlash compensation. Most important values are as follows: SCALE = 1000 BACKLASH = 0.004 Then when I hook up a digital micrometer to the axis and start jogging 1 mm each time what I see is this: - running at reasonably high speeds the backlash comp works well and the maximum difference is +-0.001 microns. - however, when I switch to low speed (really low speed) the difference can grow up to +-0.010 microns. Well, this made me think I should compensate the friction on the axis too. As I searched through the EMC2 manual I did not find anything. I looked at one of our other machines' manual (with Heidenhain control unit) which does have the possibility to compensate friction so I assume the problem itself is not unknown. Does anyone have any kind of suggestion what to do in this case?

I'm using one on my smallest machine, and it does a great job. Very nicely machined nose allows mounting, the motor is fairly quiet (compared to the Porter-Cable routers on two of the other machines). The max cutter shaft diameter is .125. It uses a collet similar to the Dremel, but it is split in thirds rather than quarters. Feel free to contact me off-list if you would like to see how this works for me.
