Hi Art:
Did some more testing,
>>1) when a e-stop is activated, if mach 4 is in enabled mode, you cannot get back to enabled, even though the log says e-stop cleared.
The system seems locked , until restarted.
When you press enable do you get any message about what causes it to drop back into Estop? Is the EStop switch showing active?
>>also noticed that I have to press enable twice for the very first time, before the motors are engaged. Could this be related.
No, thats normal.
>>> The enable locks up only if you do an estop (still Locke) , then press enable.
>>> if you reset the estop first , it will enable ok.
Checked the history and nothing is shown
Once locked up, the enable is sort of greyed out, could this be a safty feature / bug of M4 or is there a special button somewhere to unlock it?
The sequence in history is:-
..Estop condition
..signal 5 set to 0
Then reset estopbutton
..Estop cleared
at this point the enable is red and locked.
>>2) when I reference home, the dro zeroes , without searching for the home switch, as if it thinks its already at the home location.
Darwin does that if it senses the home is already made. Check the home switch in Darwins config to make sure "Active" is set to the condition
when the switch is pressed. All switches in Mach3 should be left at active high in their settings, no matter how they work..
Under the History button Darwin will put messages about a home, so if it thinks the switch is made it will tell you that. Also
in darwins config you have to tell it in the axis config which signal is the homing switch for that axis, if you havent set that it wont home.
Try those things to see what they do, based on what happens Ill boot back into xp for some tests to see how mine is reacting with latest build,
last I tested was 2805.
>>> when i press my limit switch , the history shows:-
>>>Home switch x tripped
>>>Limit X++ tripped
>>>Limit X-- tripped
>>>which is ok as I have all 3 tied to the same signal pin, physically only one switch( optical).
>>>Have set up the signal pin in darwin,sorry! I thought this was controlled by Mach4.
>>>The ref home all, now works.
>>> Can you tell me where to set the back off distance, same as Mach3.
>>I preseume darwin should do this befor handing over control to Mach4,
>>else if does not , the ref home is set ,
>>and also trips the limit, so you have to disable limits , then jog off each axis.
