Re: [Emc-users] EMC2 on read only chip!?
Jon et al. Well put! I've been running emc since you had to patch the kernel (0.9 patch , its been so long I can't remember) to get emc to run. Somewhat before the BDI's. I've never had a well checked out controller take off on me. Anytime I've had a problem I had done something stupid and found out about it rather quickly. Usually abort takes care of it. The E-stop is a pretty lonely button ... doesn't get much attention. ;-) Once an g-code program is checked out it is a LOT more reliable than the nut behind the keyboard. I put a lot of time on the machine, often several hours a day, over the years that counts up.

Re: [Emc-users] EMC 2.2.1 and G3
Here is a screen shot: http://www.wallacecompany.com/machine_shop/EMC2/wonky_path.png and the g-code: http://www.wallacecompany.com/machine_shop/EMC2/thread-ball-2b.ngc I didn't think too much about it, since the program completes properly. When I transfered the file to my HNC, which has EMC2 2.1.7, the predicted path was displayed properly. So maybe some thing changed between 2.2.1 and 2.1.7? Anyway, I made my first fully automated part today (actually a bunch of parts) -- another milestone completed. I made a movie, but it was way over 30 MB and would not fit in my website account. I'll have to figure out something else. Thank you again, to all the EMC contributors. My ballscrews, pulleys, controller and amps should be in hand next week (?) for the Bridgeport. I am a little apprehensive, because from the HNC, I have a better idea of how much work is ahead.

I have been running EMC since 1998. I have never had it cause a "wrong move" that was due to computer failure, software corruption, or software error. I have had it do a number of "wrong moves" due to OPERATOR error, one time bringing a boring head down on my hand. I thought about the likelihood of a computer malfunction vs. operator error for a moment, and then carefully pushed the RIGHT button and took the tool off my hand. I thought about hitting E-stop and winding it up manually, and decided it was me that made the mistake. So, that is about 9 years of use with NOTHING I could ever lay to abnormal operation of the software. I have also had to abort or Estop a whole bunch of CNC programs that had mistakes in them, or I forgot to set the axes correctly, or an endless number of goofs. Forgetting to set the axes at all, or making a mistake while using the edge finder and setting to +0.1" instead of -0.1" is very common, I have done this literally hundreds of times! On the other hand, my A-B 7320 CNC control croaked on me 3 times in the 9 months or so I used it before EMC was ready for real work, back in 1997-1998. This never wrecked any work, but it sure could have if I'd been cutting when it went down. (I have had an occasional hardware problem on my CNC system with EMC, usually due to bad connections somewhere, but it will show up when I try to start the system up, so I don't have tooling and workpieces loaded yet.)

Re: [Emc-users] LiveCD update
Hi Miroslav, that's even less. I'd say it's realistic to expect about 25-30.000 pulses / second from emc2 without majour problems. Regarding trapezoidal profile, it does it properly if you set the right acceleration values. S-curve profiles haven't been implemented yet.

Re: [Emc-users] EMC2 on read only chip!?
I don't think putting EMC2 in ROM would change much. The software can still be misconfigured. Probably a significant part of the $4,000 is for someone to provide support and make guarantees on performance and uptime, and probably purchase liability insurance for their company.

[Emc-users] EMC2 on read only chip!?
Hi Is this possible to put EMC2 on read only chip and use it? That thing will prevent EMC2 to become corrupted and it will load much faster. Also every time machine will start all previously safe data will be lost am less saved on external drive! No accumulated errors will occur ever! Small manufacturers here in Oregon building CNC machine and I asked him why he do not use EMC2 he said that some small OEM controller (brand new) cost only $4 000, and it is stable and original software on those controller will be never corrupted. So, question is where is big incentive to use EMC2? One wrong move of machine that ran on EMC2 will cost me between & 10 000-400 000!!! Todays parts are very expensive. When I said machine wrong move I meant software got corrupted machine stop or made wrong move etc. I am sure that open source software for machine control must have different requirement in compare to open source software for word processing or video graphic. Because read only chip become very cheap it should not be a problem. Aram - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] LiveCD update
Hi Alex, I'm about to use emc2 to drive my embroidery multihead machine. But, I'm not shure about speed. Embroidery machine runs at 400 rpm.That means Emc2 must generate up to 600 pulses in 75 miliseconds, at two independent paralell port lines, and with acceleration and decceleration phases, trapesoidal (or S-curve shape if possible). After this is 75 miliseconds pause for preparing next pulse generation. Question is: is this possible ?
