I've tried this install and test on two machines now. The test reults just seem way to low compared to what I've seen others machines on this forum doing. Mach3 is the latest version just downloaded last week.:

#1 HP Desktop, P4 3GHz Processor, 2GB Ram, Integrated graphics, XP home. Was unable to convert install to the standard PC. Removed most all start up services, except the ones that looked crucial for basic function. No startup programs or other programs installed. Performed all other optimizations. Set the PP in the bios to ECP, and EPP separately to confirm test.

25KHz
16500 Pulses Per Second
57uS short
63uS long
Graph fairly steady...Looks good

#2 Abit BH7 mobo, P4 1.8GHz, 1GB Ram, ATI 9700 128MB Memory (AGP) Graphics Card. XP Pro configured as Standard PC, APIC off in BIOS, Removed most all start up services, except the ones that looked crucial for basic function. No startup programs or other programs installed. All other optimization steps completed.

25KHZ
12500 Pulses Per Second
79uS Short
85uS Long
Majority of graph is above the max scale of 80uS

on both test the APIC constant is reported as 8100, and the APIC light is green??? I will be using this to control 3 stepper motors on a router table.

I would have expected that the PPS would have been over 35K or so, based on what I've seen other machines report on here. I'm ready to dive in, so I'm all ears.

Update -
I did the OriginalDriver.bat change as mentioned here ( http://www.machsupport.com/forum/index.php/topic,13634.msg89890.html#msg89890 ). This worked on the #2 machine that has the XP Pro with the APIC disabled; however as I feared, it caused the #1 HP machine still using APIC to freeze the driver test application.

Also, is this file swap procedure only changing the way in which the speeds are reported/calculated, or is it changing some feature which allows the test to run at a higher rate?

I'll have to get my stepper motors resolution figured out, and ball screw pitch to see what frequency I'll have to run to get the speed the system is capable of. Does the smooth stepper require USB2.0 or will 1.1 work?

Thank you,

What version of Mach? You say the latest but say last week, there have been recent driver issues due to an update that was done for threading and it seems to have introduced some weird problems for a few. Try Rev 034 as that is the latest, if not try going back to 029 or so.

Version 3.042.033 Mach3. I see there were some updates in the last few days. I'll try giving 3.042.035 a try. especially since my #1 PC is a 3.0 GHz processor.

Thank you,

did an un-install of Mach3, re-booted the system, then a re-install with the new version (3.042.035). re-booted the system again. the driver test worked awesome....was able to test and read up to 100KHz; however, mach3 will not open. The error message returns art code 1, and art code 3026 (I believe). I'll try and attach the dump file here.

happy to see the test worked on that machine. But, I want to load the latest on my other machine, but I'm concerned if it will lock it up like it did this one.

This test was done with the NON-Disabled APIC machine.....If I load it on the #2 machine with APIC disabled, should I run the SpecialDriver.Bat file?

Thank you,

I will mention this to Art but probably best for the time being to go back to an earlier version unless you specifically need something in these later versions.

Ok, I will try. Oddly enough in the archives I see a Vers. 3.043.000 but the modified date is 12/24/2008. I also don't see a version 3.042.034??? I will try to load .033 back on when I get the chance.....I was just so happy with the driver test results of .035. Of course, driver test results don't make a machine run 

Do you think it was a problem with the un-install?

Thanks hood.

When you uninstall, manually remove the driver from the device manager.

Art found an issue with the build of 035, try the 034 version again as I am not sure if that has been updated or whether the next one will be.
Oh and download it again rather than just try the version you have already downloaded.

Hi, Hood

It's the 515 drive, So it hasn't been updated, Do you have the latest one and could you post it. ?
Think it's 517.
