[Emc-users] Emco 140 lathe retrofit
Hello. I have a Emcoturn 140 lathe. i am going to use linuxcnc for retrofitting, and i will use the 5 ph stepper drives. but does anyone know anything about step timing for these drives?

Bj?rn: I don't have an Intel D525MW in my stable of motherboards but I do have an ASUS AT5NM10-I whose numbers I posted last year to the table of latency-test results in the Wiki. Your pre-spike numbers are reasonably consistent with the numbers I got. The best numbers I posted were obtained with hyperthreading turned off in the BIOS and isolcpus=1 set in the boot parameters. Nothing heroic. I did my tests long before list discussions brought out the importance of other parameter settings like idle=poll. In recent shortterm tests, I also have not seen dramatic improvements manipulating these parameters. Testing this ASUS board, I haven't seen the kinds of spikes you are experiencing. (Just for the record, I was testing LinuxCNC over 10.04LTS with the RTAI kernel). I'm curious to know what all is attached to your motherboard, especially anything attached via USB. I once had a motherboard that started misbehaving when I switched from a PS/2 mouse to a USB mouse and a number of us have seen the simple act of plugging in a USB thumbdrive cause bursts in latency numbers. Is it possible you have a peripheral interface/device that is waking up on the same time scale as the occurrence of your spikes? My system guy never failed to ask if the computer were plugged to a live outlet as his first step in diagnosing problems. Obviously your computer is plugged in but how are the power supply and the AC mains? Adequate, stable, clean? Regards, Kent I bought the power supply together with the D525MW board. here are a link - http://www.ebay.com/itm/160721043666?ssPageName=STRK:MEWAX:IT_trksid=p3984.m1438.l2649 it says 60w but i don't know the quality of it. I will test another one when i get it in a week. I to have seen the problem regarding USB and latency on my mill and plasma table. I told the guys in the shop to transfer files from USB thumbdrive to desktop and remove USB thumbdrive before running Linuxcnc at first i started out with a wireless mouse and keypad with a USB dongle, but replaced it with USB when the spikes appeared. i have now tested using a ps2 mouse, i do not have a ps2 keyboard so that's still USB. but i have tried to disconnect and connect it while the latency-test where running and no spikes i left it out and no other USB devices connected, let the test run for 5-6 hours but still spikes at 5 - 6. just a tought, what about SATA and SSD disk could that have some influence on the latency? But anyway i still think i have some powersave funktion running. I noticed that the screen was black when i come back to the office, witch i havent seen before. I think i have to go back to check my bios version to see if there are an uppgrade or alternative.

Re: [Emc-users] Latency problem
snip /I keep mulling over this 5-6 hours observation. I know we recommend running the latency test for a long time but I don't think we understand why these spiking events show up rarely. It's all well and good to blame power saving features in modern CPUs but they are functioning over much smaller time scales. If they are involved in 5-6 hour spikes, then it would seem we're experiencing some sort of perfect storm phenomenon./ You are probably right, this happens after to long a time, and not the same each time either. But i am still suspicious to the blank screen. All screensaver functions are already set to never thats a bit of a mystery. Now i have updated BIOS but no new options to turn of ACPI and still the same latency. so thats a dead end. The Picopsu is rated 80w as you say, but the 12v brick that came with it is only 60w. and i see in the manual that G0 = Full power 30 W but G1 = 5 W power 52.5 W then with the SSD it could be that it's to smal and running hot. I will test with a real powersupply after the hollydays. To be continued.. Tusen takk for hjelpen.

Re: [Emc-users] Repost: Teach with joystick. (Welding)
Yes i agree, that would have been ewen better as you tend to go slow in compex mowements, but then again the track would be better when the mowements are compex and more coarce if you are going fast straight foreward, a solution for the standstills is too just stop the clock if there are no mowement. i think i hawe too play a litle with this too se how it works.. Bjørn.. on., 13.08.2008 kl. 09.36 +0200, skrev Jonathan / Hydra: A more elegant solution based on the same principle if you need a continuous track would be to generate a probe hit signal when the the current position has moved more than XX units from the previous position. That way you don't generate uneeded points when standing still/moving slowly and they won't be too coarse when moving quickly. Something like that should be implementable in HAL, right? (Some variables for the last recorded position, compared with the current position and some logic elements).
