General Mach Discussion / Re: m5 kills all outputs

« on: April 25, 2013, 10:04:23 PM »

Icing on the cake: 

Psyched to have everything sorted, I started putting misc. BOB's back together and getting cables re-routed back to their proper locations.  Unplugged the G540 and relay board, but somehow left the DC spindle motor plugged in.  Pulling the cord around, touched a bare end to the computer chassis... "pop!" "flash!"  Fried the Sherline Speed control board.  Laughing to keep from crying.  Will order another board tomorrow.

But cheers, anyway, Hood.  I really think the finish line is in sight (despite myself!).

M3 was already using 6, so now it's m3=5, m4=6; does that seem OK?

Next time you're in Boston, the first round's on me.

ok... I "fixed" the problem....  Not sure why this works, but I changed my ActivateSignal (Output2) macro to ActivateSignal (Output3).  Then I configured Output3 to be EXACTLY the same as Output2 and disabled Output2.

So, M5 seems to disable Output2 regardless of port/pin setting?  I tried several different pins for output2 while stabbing in the dark and nothing seemed to protect it from M5.

Hi Hood,

Thanks for taking the time to help with this - I'm nearly at my wit's end...

I checked your xml and the same thing is happening:  Activate outputs 1 & 2, start spindle.  When m5 is entered, output 2 deactivates (but not #1).

I thought maybe the ESS was ignoring Port #, which would cause a problem with output 2, as it is on pin 1 of Port 2 (the spindle uses pin 1 of Port1).  So I re-wired Output to Port2 Pin2.  ....Same problem....

Can you send me your "new" xml?

Thanks!

Additional info:

M5 doesn't de-activate inputs if the spindle isn't already running.  For example: 

Activate output 1, enter m5 = Out1 is still activated. 
Activate output 1, enter m3, enter m5 = out1 is deactivated. 

So that made me think the motor is feeding juice through the ground to the rest of the system, but a) the G540's spindle outputs are opto-isolated and b) even Mach3's diagnostics screen shows the outputs being deactivated (it's not an electromechanical thing).

Hi all,

I am excited to have a new ATC and spindle control all hooked up on my 24" x 24" Techno CNC!  However, before I can get started I have to sort out this funky minor issue:

m3 will start the spindle via the Gecko G540 (Port 1 Pins 14 & 1).  m5 stops it.
m101 activates Output 1 (Port 2 Pin3)  M102 de-activates Output 1.
m103 activates Output 2 (Port 2 Pin1)  M104 de-activates Output 2.

However, for some reason, M5 also de-activates both outputs.  Output 1 re-activates after a moment, Output 2 remains deactivated.  

I had a similar problem when I was making my solenoid bank and a diode on each helped eliminate feedback through the ground when the solenoid discharged.  Since there is now a diode on each solenoid - and more importantly, since the spindle is being fed from the G540 directly (not the solenoid bank) I'm confused about where the cross-feed is....

Any ideas?

What am I missing?

!!!! Awesome.  Thanks!
