I've installed build-essentials, and am compiling the latest avrdude (AVR programmer client). The version in the ubuntu 8.04 package won't support xmega or their PDI programming interface. I'm still figuring whether it can work with a minimal JTAG interface like the neat one you describe.

I'll have to try and remember it! If that's a bit long, the bunch of German telecommunications engineers I worked with for a few months in Munich, just used "Dingsboms". (Pronounced dingce-bomce, rather than dings-bombs, i.e. sharp Ss.) Sometimes, "Dingsda" was used instead. That's probably the easiest form. With my limited German, it was a very useful word, I found. (Especially in the design labs where I worked.)

Re: [Emc-users] More Intel D510 strangeness?
I have had a similar problem booting from CD / DVD drives. In the end I booted from a USB memory stick - this worked well. I've now installed Ubuntu 10. distro with EMC 2.4.5. Checking DMESG output for parallel port info. I see only partport0: PC-style at 0x378, irq 7 [PCSPP]. I've turned off hyperthreading, set the port to EPP in BIOS and have ISOLCPUS=1 in my GRUB config file. System seems to work well with latencies of around 6000 ns on the base thread. I have tested EMC using a .ini file base period of 2ns - all seems well and much better than my old AMD based motherboard. At present I'm waiting for my 7i43 card to arrive and so I am interested to see what happens with the parallel port issue. It seems that is can be forced to EPP mode however, Ubuntu should detect the available modes - a bug?

It seems there is an overlap of functionality between CAM, O and G that could become a detriment to the whole (feature creep?). I find the simplicity of G0 and G1 appealing.

Re: [Emc-users] Question about G81
Gentlemen, I can see many cases of ABC motion in a canned cycle being very useful ie. a cylindrical part in a rotary table. A canned cycle could easily drill multiple holes in a cylindrical part with multiple holes in the periphery of the part. I can only imagine a few ABC configurations where the command would not make sense. It seems XYZ/UVW could be mixed and useful. In use I suspect it would be subject to moments of terror. :) thanks Stuart -- dos centavos -- Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Question about G81
You can't get rotary motion within a canned cycle. The documentation alludes to this: Rotational axis words are allowed in canned cycles, but it is better to omit them. If rotational axis words are used, the numbers must be the same as the current position numbers so that the rotational axes do not move. The documentation isn't exactly accurate about the current implementation: If the canned cycle G-word and the rotational axis word appear on the same line, it's currently rejected with an error: G81 ... A90 but if they appear on subsequent lines, it's accepted but the behavior is probably not what the operator desired: G81 ... A90 A future version of emc will correctly tighten the use of incorrect axis words in canned cycles. It will consistently reject ABC no matter what the active plane is. If the active plane is in the XYZ family, it will reject UVW. If the active plane is in the UVW family, it will reject XYZ. I've chosen to hold this change until the next new-feature relase of emc (e.g., 2.5.x). It won't be in 2.4.x for a number of reasons. First, the way to avoid this problem is simple (don't specify the rotary axis words where they won't have the desired effect). Second, just in case there are existing part programs out there with the rotary motions specified and that *do* work as intended (for instance, because they respecify the current rotary axis position) , I don't want to cause them to be rejected in a bugfix update to the software. I'm also not against allowing all axis letters in canned cycles, but the difficulty of implementing that is much greater than the difficulty of just adding the proper checks to make sure that whatever is accepted will behave sensibly. The assumption that only 3 axes are moving during a canned cycle is seen pretty thoroughly in the canned cycle code.

There are thermocouple to digital converter integrated circuit,( e.g. Maxim MAX6675) which would be a good place to start if you want to build something.

Heck, the new house thermostat I bought about 8 months ago has the PID fuzzy logic built into it. After a learning cycle or two, the thermostat knows exactly when to turn the heater/air conditioner on so that the house is at the set temp by the set time. Pretty cool stuff. Watlow controllers are one of the more used PID temp controllers out there, and you can always find a bunch of them available on eBay. Probably need an SSR to carry the voltage of the heat elements in that oven though, so look for a Watlow controller that has either logic voltage or DC voltage as it's output. You can find controllers with built in relays, but they won't be able to handle the voltage or current necessary for the oven that Igor is looking at.

Re: [Emc-users] Programmable temperature controller software for linux?
Igor, Wouldn't a PID temp controller be cheaper and easier? I use a Honeywell PID temp controller on my bamboo heat treating convection oven, but you can usually pick up a Watlow PID temp controller on eBay for under $50. And, once the PID controller "learns" the ramp up and ramp down times and temps for the oven, it's all automagic.
