Title: Toolchange triggers limit switch = reset of current program [Print This Page] Author: denishegemann Time: 2019-12-18 06:14 Title: Toolchange triggers limit switch = reset of current program Hey there, when my program calls M0 for the tool change my Machine moves to the top end of my z axis and triggers the limit switch. The result is that my program gets stopped and I have to start it again by manually typing the line it stopped before. How can I prevent the from happening?
Thanks for your help! Author: jjae6 Time: 2019-12-18 19:24
Maybe #82 "Z axis safe height" ? Author: denishegemann Time: 2019-12-20 20:19 Last edited by denishegemann In 2019-12-20 20:24 Editor
No, that is 5mm thats not the reason. The spindle also moves to top z-axis position at the beginning of the programm. however, just at the tool change event the limit switches cause an alarm and prevent the machine from continuing Author: denishegemann Time: 2019-12-20 20:22
this is part of my g-code right around the toolchange (2D ADAPTIVE1 4)
M5
M0
T4 M6
S24000 M3
G54
G0 X-50.813 Y65.255
G43 Z4. H1
Z-2.6Author: jjae6 Time: 2019-12-21 03:12
You can test :
- Remove all internal text of "safez.nc". Please backup your file before.
- Look at some value in the "eng" file that moves Z axis above limits.
G43 i think is not supported.Author: denishegemann Time: 2019-12-21 18:56 Last edited by denishegemann In 2019-12-21 22:51 Editor
1. I'll try to look at the safez.nc file. Where do I find it? on the usb?
2. I use the mach3 post-processor I got recommended in your facebook group. What postpreocessor should I use if G43 is not supported or how should I modify my gcode to only use the supported g-code?Author: jjae6 Time: 2019-12-23 18:00 http://bbs.ddcnc.com/forum.php?m ... ge=1&authorid=8
