Pablo:
 
    The old single pulse threading is not something Id want to add to Darwin. This means IF I add threading it would be by encoder only. Im not
opposed to adding it, but Id want to know the  numbers warrant it. Since Darwin takes a license , once M4 is fully released we'll know fairly quickly
how many are running the PP, and through threads such as this it wont be hard to tell how many want threading. If numbers are large enough, Ill
add a threading to the driver. Otherwise , it will be spec'd as having no threading capability.

Thx
Art


Well... put a +1 on the want threading column :)

  Not at all. As I said, Im happy to commit to adding it if indeed there are enough users that would use encoder
threading from the printer port.  Its not a matter of not wanting to do it or anything, its just a time management issue,
I'm fairly busy on at least three fronts and I dont like to shortchange anyone.

  I might add I even have an emco lathe that sites behind me on my workbench...Id only have to add an encoder
instead of that single pulse..

 " You can set a spearate one, OR just check the box labeled "ETrip" on the home switch signal in Darwin. The switch will then be both a limit
and a home. It will turn off as a limit during homing, or when you reset after hitting it trips an Estop, and it will reengage when you jog off it."



Hello Art, you can mark me down for wanting threading too.... got my home and limits working perfectly.... I was trying to make that way more complicated than it needed to be.... Thanks!!

Patton:

  Theres one more trick you CAN do.. map the home switch as X-- limit as well.. If you do that, youll find after homing that you cannot jog past the switch in the x-- direction, but you can jog away from it..

 Just in case it helps..

Hi art got the spindle working good its a little bit out on the slow side but that's ok.
what I had to do was set the speeds at 0.000-98000, 98000-180000, 180000-220000.

Hi Art

Darwin 1.145 fixed the Darwin regs forgetfulness bug. I shutdown and restarted M4 several times and settings stay the same. I changed spindfreqhi to 800 for my step/dir spindle and it stayed rock solid thru all the shutdowns and startups. Thank you
