Please Help - How to Configure a 5 Axis Head-Head

Okay did that, seems like we're getting closer. 

Edit: I don't see postgui_list.hal in this configuration...

Heyyy, so close now!! Axis gui opens, can jog xyz. 

Getting some errors popping up and when I try to jog rotary axis (joint 4 in picture) I heard the steppers switch off the controls grey out, and I have to "toggle machine power" to get them back.  Cannot get rotary axis to move at all. 

edit: messed with is some more.  Still getting "follow error" on rotary joints.  Also go the error "unexpected realtime delay on task 0 with period 10000000"  then told me to "Run the Latency Test and Resolve before continuing" 

edit2: the servo_period under [EMCMOT] didn't carry over from my original configuration. I corrected that and am still getting the "follow error" 
 

Aciera, I really really appreciate all your help!

I suspected something similar, and I noticed that my joint configuration from my initial ini configuration didn't make it over into your .ini file. So I copied my stuff from my file over for joint_3 and was able to get the A axis working on the machine.  By my caluclations there should be 37.68 pulses per degree on my machine (my gear reduction is very low) and I am forced to run the axis at a low velocity because of lack of torque. I am going to save a backup of your .ini file that we fixed and then go to work trying to get this working this evening.  Will post updates! Thanks again!

edit: tommy, i think it was because of the pulse/deg being set way too high. So I hope you're wrong cuase I dont want to but a computer haha.  Hopefully will find out tonight!

Okay been messing around.  Found out my pulse per unit was off by about a factor of two (two leads on lead screw and didn't calculate gear reduction correctly).  

Anyway, I am still having two issues.


One: should be pretty simple but is reallyy weird and a little long winded. The XY home switches are not working (the linear axis are just using simple switches currently running on 5V drawn from some of the Mesa boards open 5V pins).  But they were working, then they stopped.  And I don't think I changed any code that would effect that (and no matter what I do nothing seems to change it's function).  The X seemed to be working fine and then stopped, and the Y worked like once and then stopped.  I checked for continuity on my switches with a multimeter, they're good.  Mesa lights a LED when there is a pin connected.  It seems I am getting the X to connect, but not Y.  So I think there may be a wiring issues with Y.  Though that doesn't explain why it worked once and then stopped.  Right now I set my seek and latch velocities to 0 so that they would home in place and I could try to figure out the TCP.  But, I obviously want to get the home switches working. Is there a good way find out which of the 7I96S input pins are going high? This would really help me trouble shoot these as all I have are these LEDs to go off of (and it seems like some amount of parasitic voltage is causing them to light up ever so slightly when a sensor cable is plugged in, so I am wondering if that is causing the issue).  I added my .ini and .hal files incase those are relevant (I have the X set to home since I was testing with that).

Rotary axis. It looks like my rotary axis are lit up on the Mesa when they are not in the home position (again, maybe some leaky voltage) and then when they are in the home position they get really bright. These are 24V NPN sensors and these do seem to be working, so maybe the higher voltage is helping? I tried plugging my latch switches into the 24V, but since there isn't a 24V return on the Mesa they didn't seem to work (idk how the NPN are working). Worse case I can replace my last two latching switches with NPN sensors, not a big deal... But my XY probe does need to be 5V so I would be worried about that... 

I know that was a lot and was probably kind of confusing and I apologize for that. But I have been messing with it for a few hours and it's not making any sense.  Maybe a fresh start tomorrow will help. 


Two: Aciera, I am still getting a "joint 0 following error" when I try to move the machine in TCP mode. It seems like it is working for a moment (other than I need to change direction of one of the rotary axis) and then kicks the control off and throws up that error.  0 is the X axis and that one is the one that is moving the fastest (testing by driving b axis), maybe I just need to increase max velocity of that axis? I'll try this in the morning. 

The other thing I wanted to ask about is, how do I set the pivot distance? I imagine tool length effects pivot distance, but is there another way?

Phew.
