Please help with adjusting the vacuum sensitivity on Marlin 2.0

[Kosta Yakovlev]

Hello all!

My system is: CoreXY kinematick, SKR1.1 board with installed Marlin 2.0.

Dummy termoresistors 100k on all hotends ports.

ACTUATOR_READ_COMMAND and ACTUATOR_READ_REGEX on screens.

Need to right setup vacuum sensitivity system and help to foarmig right ACTUATOR_READ_REGEX parameters string for Marlin M105 answer.

2019-09-04 13:00:15.332 GcodeDriver DEBUG: sendCommand(M105, 5000)...

Hi 

Measure the mV goint to controller pins at max and 0 vacuum = how much you get ? 

and ACTUATOR_READ_REGEX    =     ^ok.*V:(?<Value>-?\d+\.\d+)        nothing else on end.

Thank you for answer, Mike.

I can change dummy resistors value from 100k to other else and via M105 look to the answer from the motherboard.

I am not sure ACTUATOR_READ_REGEX = ^ok.*V:(?<Value>-?\d+\.\d+) is right string. This right for Smothieboard classic software, but not for Marlin.

Marlin gives the answer (after M105) in a different format, it differs from the smoothie answer.

I recommend you enable SHOW_TEMP_ADC_VALUES in Configuration_adv.h.  Then you will see the actual values being read in the log:

GcodeDriver DEBUG: sendCommand(serial://COM12 M105 ; read temperatures (vacuum), 5000) => [ok T:64.17 /0.00 (576.56) B:25.00 /0.00 (1023.00) T0:25.00 /0.00 (1023.00) T1:64.17 /0.00 (576.56) @:0 B@:0 @0:0 @1:0]

 ReferenceActuator DEBUG: V2.read(): 64.17

Here is the REGEX:

         <command head-mountable-id="ACT1566773588505" type="ACTUATOR_READ_COMMAND">

            <text><![CDATA[M105 ; read temperatures (vacuum)]]></text>

         </command>

         <command head-mountable-id="ACT1566773588505" type="ACTUATOR_READ_REGEX">

            <text><![CDATA[^ok.*T0:(?<Value>-?\d+\.\d+).*]]></text>

         </command>

         <command head-mountable-id="ACT1566773612067" type="ACTUATOR_READ_COMMAND">

            <text><![CDATA[M105 ; read temperatures (vacuum)]]></text>

         </command>

         <command head-mountable-id="ACT1566773612067" type="ACTUATOR_READ_REGEX">

            <text><![CDATA[^ok.*T1:(?<Value>-?\d+\.\d+).*]]></text>

         </command>

Bill - can you give a tip for me ?

Hi Mike,

Can you post a detailed log of your pick operation?

[Mike Menci]

Hi Bill 

see screen shots enclosed: for N2 is as for N1..

I hope this helps for start?   Unfortunately my Down Camera is mnot cooperating with me now :-) and cant start a job.. to print - need to restart computer.. 

Will come back in a little while.... 

Thanks Mike

Here te trace and debug Log enclosed

[Bill Ruckman]

It looks like there is no M105 or M106 command being sent to your controller.  Probably something wrong in your machine.xml file.  Maybe a ID mismatch somewhere.

[Mike Menci]

Hello Bill,

I delited and renameds actuators, restarted Open PnP and I get the same error..

I have enclosed all in one screen shot + new Log enclosed... There must be my mistake or its a bug !?

[Bill Ruckman]

Hi Mike,

You are getting closer.  I see the M105 command is being sent to your controller now, but the data is 0.0.

  

2019-09-11 10:09:11.151 GcodeDriver DEBUG: sendCommand(serial://COM4 M105, 5000) => [ok N1:inf /0.0 @0 N2:inf /0.0 @0]

I think your REGEX should be ^ok.*N1:inf /(?<Value>-?\d+.\d+).*

There should be a line in the log after the sendCommand that looks something like this if it is working properly:

2019-09-11 10:09:11.152 ReferenceActuator DEBUG: ReadVac_N1.read(): 0.00

You don't really need to define M105 and M106 in your smoothie configuration.  M105 is built-in and, as you see in the log, it returns the value for both.  Just use N1 or N2 in your REGEX to extract the correct value.

[Mike Menci]

Hi Bill - Yes I am closer - I get the read values and I know now where the problem is - my  power supply to sensors - when it is higher than 4.0V DC than they stop responding and I get no readings.- made as per description here - Open PnP V1 but I never realy used readings  with placement - now I have feeders and if there is a miss-pick they will help me;

... Need to work on this problem - tomorrow is a new day..

Thanks

Hi 

I fixed the power supply and readings (M105) go in log now,.. but seams no compare is done and nozzle stops at trash location and error pops out ...

I tested with REGEX-   "  ^ok.*N1:inf /(?<Value>-?\d+.\d+).* " but no difference - ??

see logs enclosed

any tips guys ??

Mike
