Hi Tom,

 software 4.33 

  Single point threading with spindle in M04 direction.

   Trying to execute the following code in a lathe application:

N002 G40 G80 G49 G90 G18 G28 M5

T8 M6

 G0 G43 H8

 G97 S750 M04

 X.109 Z.10 

 G1 X.074 Z-.09

 X.056

 G32 Z.10 F.0197

Machine stops and will not process the g32 line, gives no alarm message, just hangs. If I change the spindle direction to m3, then it works fine, and cuts the thread.

What am i doing wrong here

   Thanks

Hi,

That issue should have been fixed in the Released Version of 4.33.  Are you sure you are running the Released Version and not a previous test Version (it should have been fixed in 4.33i).

Otherwise when you command M4 does your spindle run in the reverse direction than M3?  Does the Encoder Position in the KMotion Axis Screen for the Spindle count in the reverse direction as well?

Regards

TK

Hi Andrew,

Actually 4.33 is the final release that would be after Test Release 4.33i so if it reports that you should have the fix.

From your response I can't tell if you verified that M4 actually rotates the opposite way and counts the opposite direction.

Tom,

   Thanks,

   I must be pre 4.33i on this machine. under help/about tab it reports just 4.33 as version.

   Yes spindle runs counter to M03 and position counts fine.

  I will upgrade this unit and see if that takes care of it.

  For now I just used the opposite hand threading tool, and M03 to cut the tread and it works fine.
