@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.
-
Thanks for the input , tried all of your suggestions
changing the H value didnt seem to have much impact
changed the G1 to G4 ( my mistake )
R0 and R1 did try it but it should not make a difference
M201.1 it thought this had fixed it but on the 14th try failed to move front left stepper
will try tweeking a few values to see if i can make it more reliable -
@moth4017 since your Z steppers are geared, you may run into issues there, so the H value might need to be adjusted accordingly
-
@oliof
i have thought about the gearing but the stepper motor is still doing the same amount of steps , but the back EMF generated may happen sooner as there is more torque required, so maybe thats why the M201.1 was a little more reliable -
@moth4017 - whats not working ?
-
Hi after a print is finished i send the Build plate to the bottom of the printer (core xy ) i have 3 Z motors belt driven.
when the bed is give the instruction to go to bed max ( gcode above) one or 2 of the motors will not be driven intermittently , sometimes this causes the Bed to fall off not ideal ..
-
that sounds like your mechanical system may have binding and is only marginally related to stall detection ... unless the binding is strong enough to trigger stall detection.
-
the belts and the gearbox's are very smooth running, i have built printer with ACME threads and these were very smooth but i think the belts and gear boxes could be as good or better.
Keep coming up with things i may have forgot.
did more testing tonight the M201.1 has defiantly made an improvement, played around with the H values did not seem to have any major effect other that a bigger/louder stopping noise until i went too far and didnt stall at all.

if you have stall detection enabled, you may get stall warnings, that's normal. I tend to get them during prints on Z when I do fast Z hops because the sudden stop during those moves also generates back emf.

@oliof
thanks, that's interesting to know, ive mainly seen them on Z axis , but have also seen them on X too now and again.i suppose i could set a new sensitivity (S parameter) at the end of the homing routines .
