@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 ?

@danielkrah
Hi are you using sensor less homing on your Z access? -
@moth4017 oh you're asking on sensorless for Z? That's quite likely not going to work since unless you're taking special precautions a) you can't move the Z fast enough b) your print head has to be super rigid so it doesn't just flex when it hits the print bed c) you'll need a rigid print bed that doesn't care about getting hit with the weight of the full gantry.
And even then, the lack of precision on sensorless homing really doesn't make it suitable for Z.
-
@oliof Hi i can move my Z very fast at 10000mm/s if i want too but not recommended
my Z axis is on 4:1 gear box belt driven so speed not an issue. Im not homing at the print head but at the base of the printer against end stops. -
@moth4017 the best way forward is still to add two microswitches there. If you really insist, we'd need to see some pictures of the setup and your config.g and homez.g
-
@oliof hi set up is 3 belt drives config and homing files at stat of thread.
-
- H parameter in M915 should be set to the steps/mm for the Z axis which seems to be 320?
- lines 19/23 in home_max_z is probably supposed to be a G4 call, not a G1 call.
- Your M915s may need to have
R0rather thanR1(at least that's working for me). - you could replace the acceleration changes (line 32 etc.) by defining M201.1 in config.g with the special move accelerations.
- line 41 should not be required.
