Print cancels at the start of a new print

[GeckoBox3D]

For some reason I've come across a weird error after installing the new firmware.

My prints often cancel themselves before they have even started, weirdly though, this only happens on about half of the prints and is more likely to happen after I've already done a print, but it has also done it on the first print.

my routine: I set temps manually, slice file and then upload it to the web interface. The homing process then starts and the print will cancel after the X axis homes and then it will turn the heaters off etc, just like ending a print. My starting script in the slic3r is just G28.

my Homeall file:
M84 E0:1 ; Extruder motor off
G91 ; Relative positioning
;G1 Z5 F6000 S2 ; Lift Z
G1 Y-195 F1800 S1
G1 X-195 F1800 S1 ; Move towards X and Y axis endstops (first pass)
G1 X5 Y5 F6000 ; Go back a few mm
G1 X-195 Y-195 F360 S1 ; Move slowly to axis endstops once more (second pass)

G1 Z-200 S1 F100 ; move Z down until the switch triggers
G1 Z20 S1 F100 ; Move Z up 20mm
G92 Z0.10 ; tell the firmware that we are at Z=0.10mm
G90 ; absolute mode

My homeX file:
G91
G1 Z5 F6000 S2
G90
G91
G1 X5 F6000
G90
G1 X-250 F360 S1
G91
G1 Z-5 F6000 S2
G90

Any help appreciated.. I have checked the forums and this is a head scratcher

It could mean that the Duet is resetting. Next time it happens, please run M122 and post the report here.

M122 just tells me that a file was selected for printing. nothing else happens.

using USB and S3D yields this:

What’s your bed size?

[GeckoBox3D]

@stealthy_tt

195mm^2

[Stealthy_TT]

Try adding more bed size in the Homeall.g for example here is a modified section of yours.

G1 Y-220 F1800 S1
G1 X-220 F1800 S1 ; Move towards X and Y axis endstops (first pass)
G1 X5 Y5 F6000 ; Go back a few mm
G1 X-220 Y-220 F360 S1 ; Move slowly to axis endstops once more (second pass)

Even though your bed size is 195mm in some conditions it may take more than 195mm of travel to make it to the endstop while homing.

I noticed that in your homex.g you gave the X position 250mm of travel during homing of just X, you can use that number in homeall also if you feel like it.
