Endstop instantly triggered when homing (y-axis)
-
I got working other axes homing, but Y-axis does not seem to work. It is as if the endstop is immediately triggered when trying to move to endstop.
M119 Reports:
Endstops - X: not stopped, Y: not stopped, Z: not stopped, U: not stopped, Z probe: at min stopThe machine I have is markforged kinematics style idex-printer (one motor for each axis).

Hi,
Why do you have stall motor detection configured as well as end stops?
Thanks.

Printers: A FT-5 with the 713 upgrade bits, a custom MarkForged style, a small Utilmaker style, a small CoreXY from kit and a E3D MS/TC setup. Various hotends. Using Duets (2 and 3) running 3.4.6

@Visionary said in Endstop instantly triggered when homing (y-axis):
M350 X256 U256 Y256 Z64 I1 ; configure microstepping without interpolation
this will overload your cpu. go with x16 unless there is a specific reason

@fcwilt
It is for stealthchop. My machine used to be corexy
and I have not yet optimized/checked best values for stealthchop with the new kinematics. -
-
@Veti
It was set high as possible for silent movement.
I will try lower values, though 16x seems very low?
Can I use something like 64x or 128x?Main printer: 3-5 Axis, 400x400x450 Duet 6HC || https://grabcad.com/eetu-4/models

the driver interpolation will run them interally at x256

@Veti
I changed all microstepping to 16x and commented stealthchop related commands. This didn't change y-axis homing. It still seems to instantly "reach" endstop. After homing y-axis can be moved normally, though the position won't be correct.Main printer: 3-5 Axis, 400x400x450 Duet 6HC || https://grabcad.com/eetu-4/models

M915 not M569

@Veti
That is also related to stealthchop according to some post. Stall detections doesn't work with stealthchop . -
what kind of endstop are you using?
-
@Veti
Regular normally open microswitches. I think ill change it just be sure because I have crashed into it few times.Main printer: 3-5 Axis, 400x400x450 Duet 6HC || https://grabcad.com/eetu-4/models

That worked! thanks.
