OK one last thought you may need to check the voltage on the LPT port output. The newer PC use 3 volts which is too LOW for some of the BOBs to use reliably.

ALSO there MAY be a LPT port on the MB some newer PC have the port but you need to pluin a ribbon cable and a DB25 adapter to use it.

What OS are you running W2k,XP,vista,win7 ??  32bit 64 bit??

Another though is to Recheck your motor tuning to see IF the settings changed. Or just reload a known good backup of the XML.

OK open the window resource montor and then run MACH see if the CPU is maxing out.

What kernal speed are you running?  IS this a Smooth stepper setup?

ONE thing I have learned is that IF you have a good running setup PC wise it is BEST to use it ONLY to run the machine.  IF you need a faster PC to run new software then BUY a new pc for the software.

CNC machines do NOT made good multitaskers.

You may want to try a total unloading of the MACH software and driver and do a fresh reload of a stable version.  Been know to help. Don't forget to do the restart after the rel;oad.

Just a thought, (;-)TP

I mentioned the 2 programs because they are know CPU hoogs. Don't use them unless you need them.

Run the driver test and see IF the graph is smooth and steady. IF not look for the source.   Open the windows resource monitor and see what is hogging the system cpu time.

VB and the development of wizards / SendKeys question

« on: June 03, 2011, 05:27:18 PM »

Calling all VB gurus. Can you goive me an example of code that opens notepad and using sendkeys send keystrokes.

I read the manual and it makes sense but I cannot get it to work. It seems to have a focus problem I can't solve.

I use:

Shell("notepad.exe")
sendkeys "Just a test",true
sleep 10000
Sendkeys "%{F4}",true
end

This should open notepad insert "Just a test" and then wait 10 seconds and close notpad.  While Machvb is in focus it runs up to the sendkeys and stops. IF I click on notepad and gain focus the VB stops .

Any ideas or examples would be appreciated, (;-) TP

The big problem as you have found IS that when your machine is shut down the axis's may DRIFT from the exact position as there is NOTHING holding them in position.AND when you restat the Motoros tend to jump to the next full step. either forward of backward.

The only sure way is to develope a plan to be able to reset the machine to an exact know position in all axis's before to attemp to restart.

Here I use block of alum that has a hole machined into it an a milled top surface. It is bolted to the table way out of the way.  Then when I start a project AND I have the 0,0,0 all set, I probe for the center of the hole and check for the top of the block and write down these figures OR put them in NOTES in the program itself.

IF I need to restart I just got back and reprobe the hole and set the bit to the top of the block and type in the new numbers to the dros. This ensure that I am on the exact coords base as the part I am working on.

You can do the same thing by milling the Block square on the X and Y axis while it is bolted in place. Then do a touch off on the x axis and reset Xdro then touchoff the Y axis and reset the Y axis. then touch off on Z.

As long as you did not move the block it will always return the same position.

Hope that helps, (;-)TP

Is there any error messages shown when it does it.  Sounds like  NOISE or ground loop problem.

IF it were the LACK of the carriage return it would NEVER had worked(;-).  OP said it only failed sometimes. SAME as I see here.
