Solved 1HCL probing problem with ***video***
-
I have a problem with probing on a 4 z axis machine, when the probe is triggered it backs up at a very very fast speed and the measurement is not correct. I read there has been a similar problem in the past but it should have been solved in the 3.4.1 stable version i am running.
In open loop it works correctly, in closed loop backs up to the point where the g30 command was issued and z value is wrong. Tried it with latest stable and latest unstable, same error.
For example if i issue a g30 command when i am at 300mm from the bed it goes all the way down until the probe clicks that it backs up 5mm and z is correctly set at 5 if i am in open loop, in closed it backs up to 300mm above (place where i started g30) and z still reads 5. Is there a known issue with 1HCL?
@dc42 please let us know if we are doing something wrong or there is a prob on 1HCL, we are stuck at the moment.
Any help would be greatly appreciated, as it is now i can't use it, if there is something really bad going on i'd like to know it and buy some other drivers and go forward with the project.
Could it be related somehow to pid tuning of 1HCL? If so, any suggestion would be greatly appreciated.

With firmware 3.4.2 released now, would you be able to test with that and report back?
Also please post the results of M122 and M122 B# where # is the canbus address of your expansions. Also post your config.g and any macros used to reproduce.
-
@phaedrux thank you very much. Will do tomorrow morning and report back. I guess i have to have my raspberry back to stable repository to see the new stable 3.4.2
-
Yes, stable branch, and take note of this:
This time users in SBC mode must upgrade using sudo apt update / sudo apt dist-upgrade due to changed package dependencies. If apt upgrade is used, apt will keep back the DSF packages and neither DSF nor RRF will be upgraded as before.
-
@phaedrux you mean sudo is needed?
this is i'll do, is it correct?
sudo rm -f /etc/apt/sources.list.d/duet3d-unstable.list
sudo bash -c "echo 'deb https://pkg.duet3d.com/ stable armv7' > /etc/apt/sources.list.d/duet3d.list"sudo apt update
sudo apt dist-upgrade -
Sudo is always needed, but the command has changed.
sudo apt dist-upgrade
-
@phaedrux ok thanks
-
@phaedrux said in 1HCL probing problem with ***video***:
sudo apt dist-upgrade
I updated as reported and it found 4 updated packages, than i run sudo apt dist-upgrade and it did it but didn't update any of the boards (i updated boards yesterday with unstable).
Is it ok?firmware version 3.4.2 (2022-09-13 15:04:57) is this the correct one?

@Phaedrux do you have any news by any chance? We are basicly unable to go forward with the printer because of the problem we are encountering in probing with 1HCL.
-
@highfreq are all four Z motors doing the same?

@dc42 Yes the entire gantry jumps up on all 4 corners.

@highfreq I've tried to reproduce this on a bench system with a single Z motor, but I don't see that issue. The behaviour is the same in open and closed loop mode. The only issues I saw were:
-
The maximum motor speed is lower in closed loop mode than in open loop mode. With microstepping set to x16 and Z steps/mm set to 4000, the maximum speed in closed loop mode is about 200 mm/min. That's equivalent to 133kHz step rate. This isn't unexpected, because the PID loop runs at between 9740 and 17045 Hz, and the maximum the motor can be commanded in one PID cycle is one full step.
-
If I run some tests in closed loop mode, change to open loop mode to run more tests, and then change back to closed loop mode, the motor no longer moves. Re-running my tuning macro makes it work again.
To set up for testing I do this
- Set up the motor in closed loop node and run basic tuning
- Send G92 X0 Y0 to pretend that X and Y are homed (because I am running on a bench system)
- Configure a Z probe with dive height set to H0.1
The test I run is:
- Send G1 Z20 F200 G30. After it completed the G1 move and starts the probing move, press the Z probe switch.
PS - if I create a homez.g file containing just a G30 command, then when I press Home Z in DWC it also works correctly.
What command are you running to provoke the error?

@dc42 i do G92 x0 y0 to home x and y than i run G30 and press the z probe switch than it jumps.
I don't send any G1 i just send a G30 while the switch is 30mm above a carton box and wait for the switch to hit the box.I have a dive height of 5mm, could it be the problem? Should i try 0.1mm? To be honest i didn't understand what dive height really is.
-
@highfreq I only reduced the dive height so that the motor moves back up less when the probe triggers, so that I can more easily see how far the motor shaft rotates.
I am running a slightly different version of MB6XD firmware from the standard one. I don't think it should make any difference, but I suggest you try it anyway. Here is is. To install it, upload it via DWC. After installation, M115 should return:
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.4.2+ ELECTRONICS: Duet 3 MB6HC v1.02 or later FIRMWARE_DATE: 2022-09-16 15:25:37

@highfreq I am trying to reproduce your configuration more accurately.
- When you run the G30 command, is the Z axis showing as being homed already, or not?
- What is in your homez.g file?

@dc42 thank you for your help, i am out of office now, will test everything tomorrow and will send you files.

@highfreq tomorrow is a public holiday in UK because of the Queen's funeral; however I may be online some of the time.

@dc42 I am trying updating firmware from web interface, it says i am running sbc and update only if adviced from developers i click yes but m115 command always shows old version.
Is there another way to update if running trough raspberry?
-
The video shows only one of the z axis during a G30 command, please turn on audio with phases description.

We are really at a loss now, we do not know where to look, if we configure our X axis as Z (it uses a different motor driver) probing works as expected with first touch than back than second touch than back. Using 1HCL it never works, not in open nor in closed loop. It is probably a configuration problem on our side but we do not know where to look.
One other thing, if we issue a G1 Z20 F200 G30 , he G30 is ignored, machine only execute the G1, if we issue two G1 commands on same line it executes them.
