Duet 3 mini 5+ wifi sensorless homing - Help
-
@moth4017 Ok increasing current to 1amp does nothing. It’s just the first power up and home all stalls on X axis, it looks like the printer needs to warm the electronics. But once you get a successful home all everything seems to work, oh and something the z axis would stall on homing sometimes and that have a limit swith.

what are the setting you have for the sensor less homing?
did you also use M201.1 as dc42 suggested?i did some checks on mine tonight , i still get a non home event on the first time, so im doing a double home on x and Y , as you say after the first time it seems to be ok .
im about to swap my control board so i can try different drivers , im suspecting the tcm2209 and stall guard 4 , my next drivers will be stall guard 2 ,

@moth4017 Hey no I did try M201.1, I been working on this printer for two weeks now trying to get sensor-less homing to work properly . I have two duet 2 wifi with duex5 and they working flawlessly. I know what you are saying about homing, I have to home x and y separately then home all works it’s a hit or miss.

@Karim hi, testing tonight , if i turn down the acceleration while homing it stall less, M201.1 X800 Y800 remember to put the values back after homing.
i was at , M201.1 X1200 Y1200

Try using a G1 H2 move to move the motors a few mm away from the endstops at the start of homeall.g or at the start of homex.g and homey.g. That should clear the stall status.

@moth4017 try a longer move such as 1mm and use H2 not H1 in those moves. It needs to be more than 1 full step, or more than 4 full steps if you are using the filtering option in M915.

@dc42 Hi tried the H2 and changing distance moved , 1mm = 10 full steps on my printer , but still have random stalls on the Y axis so far .

Are they stalls right at the start of the homing move (i.e. immediately after your 1mm G1 H2 move), or stalls part way through the homing move? If they are right at the start then try lower M201.1 values e.g. X300 Y300.
Which firmware version are you using?

@dc42 3.5.0 beta2. The stall is after the small movement

@moth4017 Mine stall at first homing, X would stall, but if you get X to home successfully. Home all work every time, but if printer is power off overnight in the morning you have to go through that procedure again.

@dc42 Did some testing tonight setting M201.1 to x300 y300 seems to be working at the moment , ill keep an eye on it over the weekend

Try using M201.1 to reduce the acceleration during homing.
