M0

Try removing the M0 in you end gcode

Do you have any start/end gcode in your slicer?

dc42

@secure also, do you have a stop.g file; and if so, what does it contain?

secure

Thanks for the responses.
I recently added M0 to try if it fix problem.. Normally it was not there.
It is a custom built(2020) printer but this problem occured after I set the origin bed at center.(few months ago)
Normally the bed size is Y430 mm x X395 mm x Z510 mm.

I have stop.g file with default settigns.(no gcode)
Here is cure start gcode

M190 S{material_bed_temperature} ; start heating the bed to what is set in Cura and WAIT
M109 S{material_print_temperature}  T1 ; start heating hotend to what is set in Cura and WAIT
G28 ; home

Could it be a wrong axis limitation? I've two extruder (side by side.)
M208 X-215:180, Y-215:215 Z510

Here is bed.g file

M561 ; clear any bed transform
G29  ; probe the bed and enable compensation

Second job crash.

Is it crashing during homing of the second job? Post your homing files?
Or is it crashing during the end gcode of the first job?

secure

@Phaedrux
Totally no problem with the first job.
when I start another print, it is crashing after all the heaters are warmed up.

Homing OK
Warming heater and bed. OK
Starting actual printing for the first prime FAIL.

So it cant find the first starting point.
Sometimes crashing towards the switches(not forcing) or opposite side of the switches.(forcing)

Phaedrux

Can you share your homing files and an example gcode file?

secure

@Phaedrux
Thanks. Sure.

Gcode starting.. A bit messy but works for the first print.

This problem occured after I changed to origin at center.

Have you confirmed that your axis limits are actually valid for both tools after your change?

secure

@Phaedrux Yes. Never crashes normally.

@secure If the first print completes without issue but a subsequent print fails, then logic would dictate that something in the first print end code or a post print macro, is changing a configured setting. It would be useful to know if you always home the printer before every print or only before the first one. If it's the latter, then possible causes are that the end code turns the motors off which will then lose the homing position. Another possibility is that positioning is changed from relative to absolute and that it is not being set to relative at the start of the sliced gcode file.

To get to the bottom of this, we'd need to see everything in the sliced gcode file up to the first move, and everything after the last move. If there are calls to other macros within those sections, we'd need to see those too.
