Input problem
« on: March 06, 2014, 08:15:29 AM »
Mach3 appears to not be reading inputs from the BOB.  With the BOB powered down, I load Mach3. The screen recognizes that LS inputs are active for about 1 sec and shows them inactive (on the diagnostic screen).  I turn on the BOB and test limits and get no reaction on diagnostic screen.  Also I get no outputs.  Any thoughts?

More info from additional testing:

Deleted driver from computer and reinstalled V1.84
System runs well.
Run driver test, 25.5k
Test times out and inputs can not be read, no outputs.

Reinstalled V1.84
Runs well for few minutes, then computer locks up

Reboot computer
start mach3, run part program for 7min
run driver test while part program is running, 31.1k
driver test times out and everthing stops, no outputs possible

Replaced copy of Mach3 in C drive,  no outputs
ran driver test, only 235 cycles

Reinstalled v1.84
reboot computer
run part program for 50 min, AOK
run driver test, 25.5K
test times out after 2 min, no outputs

exit Mach3 and reload, everything AOK

Repeated this test on a different computer, different machine, same Profile
problem persists.

What is going on?

First thing is you can not run the driver test with Mach open.

I suggest you use a newer version of Mach, 1.84 is 6 or more years old.
If you still have problems after trying a new version attach your xml and I will take a look.

Tlhanks Hood,

Since my last post, I ran the machine for 3 hrs with no problems and I did not run the driver test.

I then installed V 3.04 and everything worked ok on the second trial.

Attached is the profile that I use.  See if you can see any flaws.

I am wondering why the wide swings with the driver test ranging from 31.5k to 235 cycles.

Thanks,  Quin

You will get weird readings in the driver test if Mach is running at the same time, it is important to only run the driver test on its own.
If the values you are seeing are with Mach closed then you may need to try some of the optimisation steps outlined in the doc available on the ftp site.
First thing I would do however is go to device manager and delete the drive (pulsing engine) restart the computer then double click the driver test. It will not run properly the first time as it will be installing the driver but the next time you run it you will hopefully get good results.

BTW you would be better trying a newer version of Mach, maybe 043.057 or so.

Thanks Hood,

I believe I was causing the problem by running driver test while Mach was active.  OK now.  Any particular reason why you recommended 3.043.057 rather than .066?

Ver 066 has quite a few issues, more so for Turn but some affecting Mill as well. I have personally experienced the ones in Turn and also had issues with Homing in Mill and Turn. I use external controllers so these issues may be restricted to external controllers. There have also been reports from others showing issues with 066 and that is why I often say to use an older version. I use 057 to 062 on my machines and they seem reliable.
