can anyone explain to me the following info , this was after Drive 4 failed to move the Z axis.
the only big difference i can see is the "POS" value drive 4, 40 but drive 5,6 600 and 680, what is "POS"

running M122 within the macro i can see that the drive is stalled , its not always the same drive and its a random event

Have also noticed M122 does not always report the Stalled motor , sometimes the motor does not move but is this because its NOT stalled but just didn't move for other reasons
-
Without having seen either your machine, your config.g, your stall test macro, it's really hard to say anything about your setup.
The gurus luckily wrote down their wisdom at https://docs.duet3d.com/en/User_manual/Connecting_hardware/Sensors_stall_detection
AFAIR,
posis the microstep position as reported by the driver, usually a value between 0 and 1024. it will wrap around multiple times when you move your axis. I would not worry about them being different per axis, especially if you use something like automatic bed alignment.Regarding the irregular report of stall in M122 -- this may be a simple race condition. Usually if you detect a stall for homing, the motor stops moving, so if M122 runs, the stall flag may have already cleared from the driver.

@oliof
Hi i can post everything , just when i think ive fixed it it happens again, when a motor stalls do you know if it turns of the power to that stepper motor? -
@moth4017 See the M915 description. With
R0a stall is only reported but nothing is done beyond that. If your motor stops while it should be moving and you haven't setR2/R3, then it is most likely a physical issue, i.e. binding.I can tell you that I can create stall reports on Z when enabling Z hop just from the back emf of stopping a short movement if sensitivity is high enough (-:

@oliof
Hi yes im using R0 , the file below is using R1 as i have just tried itI have 3 stepper motors on the Z axis , when i send the Z axis to the bottom of the printer , 1 or 2 of the motors will loose drive , its not always the same motor and its not all the tame.

@moth4017 what firmware version are you using? Use M115 to check.

@dc42 release 3.4.1
the one you did 7 days ago -
@moth4017 we'll need to see your config.g file and your homing files.

@Arnold_R_Clark no, you are absolutely right. Simple microswitches are far superior to sensorless homing in ease of configuration, repeatability, and reliability. I have so far spent more time dealing with weird behavior of the sensorless homing setup I am running purely to be able to show how it would work for those that insist, than it would have been to order microswitches, wait a week for them to arrive, and fitting them -- including the wait time I guess.

@arnold_r_clark hi I do agree with you, i had 3 micro switches on the z axis but I needed the inputs for other functions and as the x an y axis work fine 100 % after the first homing , I thought it was going to become an easy exercise..... yes I could get an extension board but progress of stepper drivers and software can be archived . I'm not one to give up so I have persevered for 3 versions of software and a lot of reading and testing I'm sure at some point it will be as reliable as the X and Y. Wish me luck and a few more beers ..
-
The thing is I am running stalldetect homing on all 5 axis on the same printer flawlessly. I mean its bonkers! The difference is I run the Duet 2 wifi + Duex 5 as is TMC 2660 drivers. I still find it strange that the TMC 2209 drivers act so different
-
The 2660s do StallGuard2 in SpreadCycle, the 2209s do StallGuard4 in StealthChop. They work differently, so it's not a super big surprise that they need specific tuning.
-
hi any thoughts on how i can track the homing issues ?
