General Mach Discussion / Re: Motors stalling, losing steps

Look up the specs on those steppers and see if you can find motor curves. That will give you prefomance
data at maybe two different voltages and wiring. It will show you speed vrs torque curves and that puts you into the
correct ball park very quickly. You should not be on the far end of the velocity for the motors.
It does not take much to miss a step. When missed you will know it and you back down. If they can be run solid at some lower velocity then work your way up. Yes, noise and a number of other things can cause problems. Some are easy to find others can be a PITA. So find some velocity anad acceleration value that's solid so you have a place to look for other problems if they exist.

My Christmas is a day of rest, tomorrow starts the travel to Bethlehem ( Pennsylvania   ). Till then there is still piece on Earth.

Zaaephod,
As the steppers speed increases torque decreases. You should test your particular setup to see where it will start skipping and set the max velocity such that it's approx 30 to 40% below the found skipping max speed. You need a
to leave some torque for cutting and some safety margin. You also can't have instant acceleration so ramp appropriately from start. Don't know what kind of drives you have but you may be able to increase the stepper torque by using a higher amp setting on your drives.

HI All,
Well added another pc#4 for testing, NEC LAPTOP 400MHZ / 256 RAM.
Only good to prior 12 23 08 versions and will give the ( 214 error for dec 24 ver ),
(TODO for dec 24-3 ver) , ( 406 error for dec 25 ver),
but it dosn't loose the color in the x trangles. 

Changing accel values didn't do any good. All the computers here are set to the highest accel.

Lets see, four different computers here of varying make and model all running XP. The slower ones with less than
500 mhz / 512 only get to prior versions of DEC 23. The fastest / most memory only has a problem wiith loss of color
in the pointer / unless you flip it 180 degrees ( along with oss of color in the associated dimension boxes) but can run the DEC 25 VER with no problems other than stated. 

RC, no problem with your posted file in #555.

  Beats me as if it's a Windows setting somewhere.

ART,
Getting a 406 error now.

ART,
Still getting 214 error code. Just a guess, but from DEC 17 version back, the mouse pointer didn't change to a cross
hair in the graphics part of display. The error happens when you click the "open" box in the file open pop up screen.

Willem,
No wonder none of those AMSTERDAM  dolls ever answered me.
Time to crack open the Usquaebach and enjoy.

Merry Christmas All,

Hey Willem,
Dankun, and i will be stopping, but the wife chased me out of the Kitchen saying i was eating to manny Christmas cookies.
Cookies don't go to well with beer, but are fine with scotch.
 I assume assume Swarta Pete is still giving out Black Peter's over there, don't eat too many.  Sorry for the my Dutch as the only other thing i learned over there was "IK hav ven yo", and I don't think you want to here that from me.

Hi ART,
I'm getting the same 214 error code as Chip on the LAPTOP.
RICH

MODIFIED: COMPUTER #3 -  2.4ghz / 512 ram
                Works fine on this one, error on exit,  but no  loss of X pointer color . I upgraded this computer to MACH v*********.20
                and tried files from the other two computers.

SUMMARY: PC#1 - loss of x pointer color / otherwise good
                PC#2 - can't use any version lazyturn application after DEC 17
                PC#3 - no problems
                PC#4 - CAN'T USE ANY VERSION LAXYCAM APPLICATION AFTER DEC 17 " NO LOSS OF X POINTER COLOR"
               

MODIFIED: ADDED PC#4

ART,
All versions of the LAZYTURN application dated from NOV 9 thru and including DEC 17 will work with what is loaded on the laptop. TODO as soon as the application is replaced with the DEC 23 or DEC 23-1.
The laptop is 500 mhz / 512 memory while the other computer is 3 ghz / 2 gig memory.

Computer related or application file related? Any suggestions on what to look for on my end?
RICH
