Lawrence G Ok, I finally got around to running the test you suggested. The first couple moves (test #1) up and down Are ok, but after that the tip gets lower and lower into the piece. Also the motor makes a binding noise just Before it starts screwing up. Sounds like the motor is trying to move two opposite directions at the same time. Never did get to test two. So where do we go now? This by the way is with a config file that uses + as a Z axis up And - as a Z axis down. Had a pencil stub loosely in the collet during the test and it kept getting pushed further and further Into the collet until I forced a stop to the program before the face of the collet went in to the bed surface.
John *********************** Original Text ***************************** Try the following program.... it will test the Z axis configuration for proper setup. Zero your machine with Z = 0.000 at the table top. Run the program. It will make 200 moves back and forth from 0.5 to 1". If you have a configuration issue, you will find that the final position will not end up 0.500" that the axis window is showing. ( test program to see if Z axis loses position ) ( msg, test 1 of Z axis configuration ) G20 #1000=100 ( loop 100 times ) ( this first loop has delays after moves - tests acc and velocity settings ) o100 while [#1000] G0 Z1.000 G4 P0.250 G0 Z0.500 G4 P0.250 #1000 = [#1000 - 1] o100 endwhile ( msg, test 2 of Z axis configuration ) #1000=100 ( loop 100 times ) ( this 2nd loop has no delays after moves - tests direction hold times on driver config ) ( and also max accel setting ) o101 while [#1000] G0 Z1.000 G0 Z0.500 #1000 = [#1000 - 1] o101 endwhile ( msg, Done...z should be exactly .5" above table ) m2 You can also change the G0 Zx.xxx instructions to G0Xx.xxx or G0 Yx.xxx to test the x and Y axis for proper configuration. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
