Hello all together

I build up and maschine works. 
Now i build up the Schultz controller incl. the Controller Board from here: https://github.com/openpnp/openpnp/wiki/SchultzFeeder-and-SlotSchultzFeeder

It works. I added the driver. I added the feeder by script. Then i attached physical 2 Feeder (2 times 2Lane Feeder). I Get the ID and they where found. I Use Connector one for 2Lane Feeder1 and Connector 2 for another 2Lane Feeder.  The have different IDs, of course. 

All works but: When i switch from one Feeder to the next in the Feeders menue (testing between, Pre Pick and so on) each time i toggle between feeders I get Warning: "Actuator "SchultzGetID" read Error: No matching responses found."
This comes after the timeout of the controller. Then i just Push again "GetID" and voila -> It works and finds ID. 
This also is when i switch between the the Lanes of the same Feeder. Very curious.

What is wrong ? 

Thank you a lot. Without the help from your side i had still gave up........

Andy can you post PnP Trace log ? That would help

Yes of course. 
Machine started. 

This comes up when ok detected: Means i push on the Feeder Lane 1

I tested it with a Place programm. It worked well, all Feeder work, no error message.

Maybe it is a "Schöner Wohnen Problem" ? !

Thank you very much.

I am wondering about this line: 
2022-08-29 23:50:18.125 GcodeDriver$ReaderThread TRACE: [serial://COM3] << M608N1M610N1
May this cause the trouble ?

Yes, that is causing the problem.  The gcode parser cannot handle two commands on the same line.  I'm not sure why OpenPNP is doing this.

Hi 
Is this a bug and how to find out ?

> I'm not sure why OpenPNP is doing this.

OpenPnP is not concatenating lines, ever. So this is likely a mis-configuration.

Please go have a look in the ACTUATE_COMMAND of that actuator.

Or send the machine.xml

 Looking closer, I see that OpenPnP is not concatenating the commands, but it sent the second one without waiting for a response from the first one.  The controller should be able to handle this (it can buffer 4 commands).  Perhaps it can't handle that second command coming so soon after the first.  I am able to duplicate the issue, so I will take a look at it.  The good news is that it only seems to happen when viewing the configuration.

Hi
That sounds very good. It is a very unfortable behaviour, because i try to install 10 Feeder. Every time is switch or make some changes, i have to wait timeout, and then comes error message up, which has to be pushed away. 
So if there will be a short workarround available, great !
The machine XML: I put in the original config file of the documentation, just copy and paste it. 

Now i have a different topic.
When i pick a part in Schultz feeder: The Nozzle drives to position, the shutter opens (part free), the nozzle gets down, then the shutter closes and after that the nozzle gets up !!
That means the shutter closes first and attaches  the part at the nozzle. (Then it is in a very uncomfortable position) 
Why ? Where can i configure the sequence ? 

Behaviur must: (My oppinion):
- Open Shutter
- Nozzle down
- Vac on
- Nozzle up
- Shutter close
- move smd part in Feeder one forward.

Thank you

The shutter closes when the PostPick actuator is actuated (or automatically after 2 seconds).  Make sure you have Machine Coordination->Before Actuation? checked in the actuator configuration.

I found the problem. It was the speed of the Z axis and the waiting at end positions with 5000ms. I set this for test because of vacuum trouble.


Thanks for help.

I am not shure, is there an update for this issue ? It is a liitle bit anoying when change and every time the failure pops up.
Thank youz
