EMC2 crashes everytime

[chinsettawong]

When I use EMC2 to do some works, I always start with manually telling EMC2 to move my x, y and z axises. However, everytime after a few manually entered G-Codes, the EMC2 just freezes. This doesn't happen if I run EMC2 off the G-Codes files. What is worst is that I can't stop and start EMC2 again. I need to reboot to run EMC2 again. Do you guys know what is going on and how to solve this problem? If it hangs, how can I kill the process and run the program again?

Could you give us a bit more like
linux verson
emc2 version
interface (axis, tkemc...)
computer specs
hardware (steppers, servos, interface)

thanks
sam

I use a Compaq Presario notebook with Pentium 4, 2.0 Ghz and 1 G RAM.
The Linux version is Puppy Linux running EMC2. This is actually the latest version of CD bootable version of Puppy Linux. The stepper controller card is from steeperworld.com. It has 4 axis controller in it. The steppers are 200 lb/in, 1.8 degree per step.

I have tried Puppy Linux and EMC2 on a different computer and EMC2 would freezes after a few manual movements also. Once it freezes, I close the process, but I can't restart EMC2. I'll have to reboot the system everytime it happens.

Any comments and help would be appreciated.

search down to BASE_PERIOD , and modify the ini file to suit your computer
im new to emc so im still figuring out how to get it working better , but i do know the base period setting geatly effects the performance of emc

If base period was the problem, it shouldn't work for g code files. That was my first though too. Seems like I remember something along these lines, if you post on the user email list or the IRC channel, I'm sure someone can help you.

Thanks. I'll try IRC.

Talking to the experts. They have never run into a bug like what you are describing. They are leaning towards a hardware issue.... Plus the puppy version of emc2 was before the official 2.0 release.

The comment where
run a memtest overnight

download the emc2 ubuntu 6.02 live cd to try. (someone thought the memtest was an option at boot.) from here. http://www.linuxcnc.org/ This
has a more up-to-date version of emc2.

run a real time latency test
http://wiki.linuxcnc.org/cgi-bin/emc...roubleShooting
section 1.2

also the irc.freenode.net channel #emc is where all the gurus hang out.

Thanks Sam. I tried IRC yesterday night, but for some strange reason I just couldn't see anybody in the board. I'll try again tonight.

I'll also download the Ubantu version to try out. I don't think it is the faults on my computers, because I tried Puppy Linux version on these 2 computers and they crashed the same way. It is most likely the bugs in Puppy Linux.

Thank you so much for your information.
