Re: [Emc-users] Latency Test Result Questions
Don, good thing you kept the .ini and .hal files - reminds me to make backups once again cause I think I changed the files since the last backup ... I copied my working config for the mill to 3 different machines (one active, one backup and one to play with at home) by comparing a setup generated by stepconf and changing the proper timing and addresses. Still, remember that the jitter, although it is an exact number, depends on what you do with the machine at a given moment and therefor is just a guidance number. At least this is how I see it: start the test, do all kinds of weird stuff that keeps the computer busy and get the worst number. In that case you will most likely never hit the edge in real life. But then, when the mill is running I never do all this weird stuff. This is a production machine and when it runs I do not touch mouse or keyboard. A 10% difference in jitter value is not that big. I've seen differences like this on different occasions that I ran the jitter test (on the same machine with the same software - no updates in between). This does bring up a new question: Can (will) the jitter test report different values after a software update? Since I configured my machine more than one year ago there have been some updates (I'd even say my EMC2 PC is more up to date than any of my windows machines).

[Emc-users] CNC4PC jog pendant + EMC2 - any recent info?
Does anyone know if John Thornton ever posted an ini/hal configuration to use with the CNC4PC jog pendant? I bought a CNC4PC 6 axis pendant and was researching the archives for information. I read that John was getting a loaner jog pendant similar to mine to experiment with about a year ago.

Re: [Emc-users] PCI Parallel port
Hi Will - I'm a bit tired but I recall having to try all the addresses to get my Netmos card to work - which you've already done. Looking at my config file I have quotes around my addresses (I have 2 ports, one an input only so that might be why - I'd have to go back and read docs). Also the dmesg file says something about the module parport - did you try commenting out the loadrt prob_parport? Not sure if this is what it refers to. Sorry I can't be of more assistance at the moment.

[Emc-users] PCI Parallel port
Hi all, Being still new to linux and EMC2 I have decided to use an old computer to learn more about it, using a small table top mill that I built using various parts. Wanting to branch out into a cheap I/O upgrade I decided to purchase a PCI parallel port card. But I have run into a problem getting this going. After installing the card, I used "sudo lspci -v" to find out the address, this is what was displayed: 00:00.0 Host bridge: Intel Corporation 440LX/EX - 82443LX/EX Host bridge (rev 03) Flags: bus master, medium devsel, latency 64 Memory at e800 (32-bit, prefetchable) [size=64M] Capabilities: [a0] AGP version 1.0 00:01.0 PCI bridge: Intel Corporation 440LX/EX - 82443LX/EX AGP bridge (rev 03) (prog-if 00 [Normal decode]) Flags: bus master, 66MHz, medium devsel, latency 64 Bus: primary=00, secondary=01, subordinate=01, sec-latency=64 I/O behind bridge: b000-bfff Memory behind bridge: d800-e7ff 00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 01) Flags: bus master, medium devsel, latency 0 00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01) (prog-if 80 [Master]) Flags: bus master, medium devsel, latency 64 [virtual] Memory at 01f0 (32-bit, non-prefetchable) [disabled] [size=8] [virtual] Memory at 03f0 (type 3, non-prefetchable) [disabled] [size=1] [virtual] Memory at 0170 (32-bit, non-prefetchable) [disabled] [size=8] [virtual] Memory at 0370 (type 3, non-prefetchable) [disabled] [size=1] I/O ports at f000 [size=16] 00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01) (prog-if 00 [UHCI]) Flags: bus master, medium devsel, latency 64, IRQ 10 I/O ports at c000 [size=32] 00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 01) Flags: medium devsel, IRQ 9 00:0b.0 Serial controller: Titan Electronics Inc VScom 010L 1 port parallel adaptor (prog-if 02 [16550]) Subsystem: Titan Electronics Inc VScom 010L 1 port parallel adaptor Flags: medium devsel, IRQ 9 I/O ports at c400 [size=8] I/O ports at c800 [size=8] I/O ports at cc00 [size=8] I/O ports at d000 [size=8] Memory at ed001000 (32-bit, non-prefetchable) [size=64] 00:0c.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) Subsystem: 3Com Corporation 3C905B Fast Etherlink XL 10/100 Flags: bus master, medium devsel, latency 64, IRQ 10 I/O ports at d400 [size=128] Memory at ed00 (32-bit, non-prefetchable) [size=128] Expansion ROM at ec00 [disabled] [size=128K] Capabilities: [dc] Power Management version 1 01:00.0 VGA compatible controller: S3 Inc. 86c794 [Savage 3D] (rev 01) (prog-if 00 [VGA controller]) Subsystem: CardExpert Technology Unknown device 8a20 Flags: bus master, 66MHz, medium devsel, latency 80, IRQ 11 Memory at d800 (32-bit, non-prefetchable) [size=128M] Expansion ROM at e000 [disabled] [size=64K] Capabilities: [dc] Power Management version 1 Capabilities: [80] AGP version 1.0 Assuming that this "00:0b.0 Serial controller: Titan Electronics Inc VScom 010L 1 port parallel adaptor" was the pci card that I recently installed, I used the address "c400" for the address in the .hal file line: loadrt hal_parport cfg=0xc400 The .hal file that I used was created by stepconf, and functions fine with the built in parallel port.

They allow Axis to start but cause no outputs on the parallel port card. Also, after searching the Gmane archives, I found info about Netmos cards but nno luck on VSCom. I am sure that I missed some steps in the setup fo this card but am unsure as to what they are. What are the steps that I missed to do and what can I do to track them down?

Yea - stepconf could do with a bit of tweaking so it doesn't overwrite the whole file and only modifies parameters that it knows about.

Re: [Emc-users] Latency Test Result Questions
The jitter really leads to two calculations (together with the step driver timings you enter): * the maximum step rate (bigger jitter -> lower step rate) * the direction setup/hold value (no real effect on step rate) If your configuration still starts and doesn't give the "unexpected realtime delay" message, then the first issue is no problem. To take care of the second issue, find the lines in your hal file setting dirsetup/dirhold and add 2000 to them. This number as computed by stepconf is simply the datasheet setup/hold timing plus the latency.

[Emc-users] Latency Test Result Questions
My box recently went down, and I had to re-install everything. I thought it would be a good idea to run another latency test after this fresh install. My max Jitter came out to 20,602, while my previous max jitter was 18,592. I have looked in the .ini and .hal file for a location where I can just put the new number in but have not found one. When using stepconfig, does it just take the jitter and calculate numbers based of of it. I have made many modifications to the ini file, and I do not really want to paste all of the edited lines back in, (since running stepconfig again will overwrite). Also, will the difference of 2000 really matter that much?
