Z Endstop triggerd but not stopping

JetMeIn

Hi,
I just changed my Maestro to the Mini 5+ for my Core XY machine.
I managed to config everything, but have some problems with Z.

Firmware 3.4.5
Two Z steppers, and one optic endstop.
Checking with M119 shows that the endstop works:
First: Endstops - X: not stopped, Y: not stopped, Z: not stopped, Z probe: at min stop
Than: Endstops - X: not stopped, Y: not stopped, Z: at max stop, Z probe: at min stop
No Z probe.
Config for the two Z's: M584 X0.0 Y0.1 Z0.2:0.4 E0.3

After first config, it works for a while, but than stop to work.
I'm messing around for few days with no results.....

Any ideas??

@JetMeIn Are you using G1 H1 Z... to drive into the Z endstop? If you're probing via G30, you need to set up the probe differently. Please share your config.g and homing macro as well.

@chrishamm Here are my files:homez.g homey.g homex.g homeall.g config.g

X and Y axis are fine, just the Z decide not to stop...

@JetMeIn said in Z Endstop triggerd but not stopping:

After first config, it works for a while, but than stop to work.

So the endstop works intermittently?

The config looks ok.

Though your Z steps per mm seems high.

M92 X80.00 Y80.00 Z16000.00 E6720.00

If you start the homing and then try and trigger the endstop by hand, does it stop?

JetMeIn

@Phaedrux No, the endstop not working.
It works at first start after the first config.
M119 shows that the system do see that it functions.
Steps for Z are correct for the pitch.

Can you capture a video of it in action when it's working the first time and failing the next time?

Can you show the wiring at the endstop and mainboard?

JetMeIn

@Phaedrux I will try to do so.

I need to reconfig everything for it to make it work for the first time again.
