Z-probe released with a solenoid

@marcossf, try uploading just that file again, then run M997 again.

Which version of Duet web Control is currently running? See the Settings General tab.

Marcossf

@dc42 This one:

Unable to upload the files, not even one by one.

I can try some options, try to run from USB (bossa method) or write the files directly to SD card....

You are running a version of DWC older than the version of RRF installed on your main board.

If you send M115, what firmware version does it report? Maybe it has upgraded the main board firmware already.

Are you able to upload the DuetWebControl-SD.zip file from the 3.3beta3 release?

Marcossf

@dc42 OK, done!

First of all i updated the DWC version uploading the ZIP. After that, uploaded the files remainig succesfully.

Just intuition. There isn't documented or advert anywhere.

OK, the problem was that you were running DWC 2.1.0 with RRF 3.2.2, instead of installing DWC 3.2.2 when you installed RRF 3.2.2. I'm glad it's solved now.

Marcossf

@dc42 said in Z-probe released with a solenoid:

However, RRF 3.3beta3 released yesterday already includes some of the changes to remove this limitation. If you upgrade to that release, then a G30 command should stop the Z motor even if it is connected to the tool board.

I could test really fast this with 3.3.0beta3 and its still unsolved. G30 command or home doesn't trigger when the motor isn't connected to 6HC.

The deploy and retract probe now works well in G30 or home, connected to out4 fan connector.

That's odd, because I tested it this morning (G30 with the Z motor connected to a EXP1HC external driver board). Please check that after deploying the Z probe, the Z probe status in DWC still changes from 0 to 1000 when the probe is triggered.

Marcossf

@dc42

Yes, the status in DWC detects the endstop activation.

At this moment Z motor is in the 1LC board.

I could try changing the endstop and the Z motor to the 1XD instead of the 1LC, and thus potentially fix the other added problem you mentioned.

I have thought that the probe will not be in the head anyway but it will be on the Z1 axis, so we would simply have to bring the endstop wiring to the 1XD board instead of the 6HC.

I'll test that inmediately.

I changed the endstop to 1LC where Z motor is. I couldn't test in the 1XD at this moment but serves for check as it has the same typology.

Tested, but same behaviour, the endstop activation can be seen in the DWC status (0-1000) but not stop the Z motor.

@dc42 Do you have any clue as to why the endstop does not stop the motor, both on the 6HC and 1LC boards, and yet if it detects both the DWC status and the M119 its activation?

Whatever you do, the g28, g30 etc will not stop the Z axis motor. The problem is no longer with the probe or the solenoid, there is something else.

I know why it didn't stop the motor in firmware versions prior to 3.3beta3. I don't know why it doesn't in 3.3beta3.

Please can you try configuring an extra Z driver on the main board. So your M584 command would look something like this:

M584 X40.0 Y0.1 Z121.0:0.5 E0.2             ; set drive mapping

This should cause the main board to stop the motors when the Z probe triggers, even when using firmware older than 3.3beta3. You don't need to connect a motor to the extra driver, however you will probably see "phase may be disconnected" messages.

Marcossf

@dc42 Ok, I'll try this inmediately.

Marcossf

@dc42 OK, tested

Warning: motor phase A may be disconnected reported by driver(s) 5
Warning: motor phase B may be disconnected reported by driver(s) 5

Indeed the log gives the error of the engine that does not exist, but even with this configuration, the endstop is still detected as before, but the Z motor does not stop when activated.

Physicaly the endstop is in LC1 where the Z motor is:

Endstop Z.gif

dc42

@marcossf thanks, that's useful information. I will test that configuration on my bench system.

Marcossf

@dc42 Ok, hope you could find something wrong. Ask me if you want to do any test with my HW.

dc42

@marcossf, I have tested your configuration. G30 works as it should:

Solenoid output is activated
Z motor attached to tool boards drives in one direction
When the probe is triggered, the Z motor reverses. This is because after triggering, it returns to the dive height. Your M558 command has the dive height set to a large value (25mm), so it travels quite a long way before stopping. When it stops, the Z coordinate reads 26.0 which is the trigger height plus the dive height.
Solenoid output is deactivated

The behaviour is the same (using firmware 3.3beta3) whether or not I have the dummy Z drive configured in the M584 command.

Marcossf

@dc42 Ok, tested and works well same as you tested.

The H parameter was the hint, and dificult for us to see what happened with the bare motor axis. We could test it right when H=0. Greater values doesn't retract the probe in the moment the endstop is triggered.

M558 P8 C"121.io0.in" H5 R1 F120 T5000       ; set Z probe type

We had to add a "R1" option to let the probe stabilize at bottom before touch, because if I not do this delay, the endstop triggers at probe deploy.

Also we tested if the endstop can be activated when isn't at the external board where the motor is, wich is better for our cabling, and it works also.

The problem that still have, it's when issue a G30 command, the probe deploys, the z motor moves a little, and after that the probe retracts without having been toched the endstop; it reflects Z=1mm in the DWC status. However when G28 waits for the endstop, trigger it and set the Z=0 status. Different behaviour.

I'll do some aditional tests to see what's happening.

Marcossf

@dc42 Still fighting with G30. Quick test in video, hope could unterstand it.

https://youtu.be/rOLtE_f9bOM

Video timming:
0:03 - Initial G28 move, back Z up 5mm.
0:13 - After X and Y home, the probe is deployed and start to move Z down.
0:18 - I push the probe for endstop trigger stop and back Z up.
0:25 - G30 issued after been homed all axes.

As you can see, the G30 triggers itself without touching. It is assumed that it would have to behave in the same way as the g28 (homeall.g or homez.g) does. Isn't it?
