0816 Vacuum sense

[Rashid Guseynov]

Hello.I need help with vacuum sense on 0816  Native Shield.

what do I need to enter in "actuator_read_regex" and "actuator_read_command"?

Hi Rashid,

According to this

https://docs.mgrl.de/maschine:pickandplace:feeder:0816feeder:mcodes

1. For ACTUATOR_READ_COMMAND set for sensing actuator 1
   M144 A0 ; read vacuum sensor 1
2. For actuator 1
   M144 A1 ; read vacuum sensor 2
   
3. The response seems not to be documented on that page by mgrl. So we need to "reverse engineer" it.
   
4. Set the log level to TRACE.
   
5. Try Read using the actuator panels (for both actuators in turn):
   
   https://github.com/openpnp/openpnp/wiki/Setup-and-Calibration%3A-Actuators#actuator-control-panel
6. You will still see the errors, but ignore them.
   
7. Then send the log, it will help one of us to assist for an ACTUATOR_READ_REGEX.

Hi,

"actuator_read_command"  is used to request data; "actuator_read_regex" is used to extract the final data from response.

For "actuator_read_command" , you can use M143(raw ADC value, int)/M144(scaled ADC value, float) as mark said.

For "actuator_read_command" , you can try:

^value:(?<Value>-?\d+\.\d+).*

[Rashid Guseynov]

Now it work!!!Thanks

in " actuator_read_regex  " need write ^value:(?<Value>-?\d+\.\d+).*

Hi,

Happy to hear that!  And sorry for my mistake, the second "For" is for the "actuator_read_regex" :)

In your log,      << value:0.82      is the response from 0816 controller, so you can get 0.82 now.

[Rashid Guseynov]

Yes, when vacuum pump is off value:0.82

Max negative value: -38....
