Start/Stop print Stall detected on driver(s)

macpit

Hi,

I build a new Delta and all works, with sensorless homing, Auto Delta Calibration and mesh.

G28 and G32 works fine from the Web GUI, manual started.

But within Simplify 3D i have at the start of the print Stall detected on driver(s) printer paused, then i can resume and start the print.

After the print with the end Script i have the same issue Stall detected on driver(s) and the printer paused.

My start Script in Simplify:

G28		; Home
G32		; Home and calibrate
G1 Z5	        ; Lift Z 5mm
M300 S500 P1000	; Play Beep
M572 D0 S0.25	; Set Linear

My end Script in Simplify:

M106 P0 S0  ; Turn off Fan 0
M104 S0     ; Turn off Extruder
M140 S0     ; Turn off Bed
G28 	    ; Home XYZ,

I suspect that the stall is occurring in the G28 homing move when the endstop switch is triggered and the motor is stopped abruptly. Try reducing the speed of the initial G1 S1 homing move in homedelta.g.

Hi,

I don't think is the speed, I change now my home all to:

M915 X Y Z S2 R2 H400 F0    		; set stall detect drives, S-threshold (-64 to 63), F1 filtered, R-log only
					; Hnnn (optional) Minimum motor full steps per second for stall detection 
					; to be considered reliable, default 200 (try 400 for 0.9deg motors)
M400					; make sure everything has stopped before we make changes
M913 X50 Y50 Z50			; reduce motor current to 50% to prevent belts slipping
G91					; use relative positioning
G1 S1 X700 Y700 Z700 F3000		; move all carriages up 700mm, stopping at the endstops
;G1 Z-35 F1500				; down a few mm so that we can centre the head
M400					; make sure everything has stopped before we reset the motor currents
M913 X100 Y100 Z100			; motor currents back to normal
G1 X0 Y0 F2000				; centre the head and set a reasonable feed rate
M915 X Y Z R0				; Disable stall for prevent false detect
G4 S1
G1 S0 Z-415 F3000			; down a few mm so that we can centre the head (Test maybe that's stall?)
G90					; back to absolute positioning

My start Script:

G28
G32
M300 S500 P1000	; Play Beep
M572 D0 S0.25	; Set Linear Advance

Now I start the Print,

Heating up, then go home stall detected and go to G1 S0 Z-415 F3000.
After G1 S0 Z-415 F3000 I have stall detection, but why it's detected?
Bevor that move I have disable stall detection with:

M915 X Y Z R0				; Disable stall for prevent false detect

I think it's a Bug,

Upload & Print give me stall detection, upload the same as Macro works without stall detection.

Upload & Print I have stall detection printer paused,

Upload as Macro and rund I have no stall detection...

Is there a way to solve this problem?

I am on vacation, but if you remind me a few days from now then I'll try to reproduce it.
