Recover failed print (modify g-code to start from Z height)
I was trying to save a 4 days print which was 80% finished. Basically it tried to do it using this CNC kitchen tutorial:
https://www.cnckitchen.com/blog/guide-resuming-a-failed-3d-print
This method helped me recover prints on my creality printers before. However due to the more complex startup routine of the XL I couldn’t figure out which parts of the g-code I should delete. Can you give me a hint how to accomplish this in the future?
I also posted a feature request, ideally this should be part of the firmware for large scale printers. It was only Petg so I wasted 100€, using performance filaments this could quickly be a few hundred bucks going to waste.

Same situation, I wish PRUSA will develop a solution for these situations and failed prints. Much of our time and our money in the trash by failed long prints. Firmware update is the way! Please @PRUSA team !!

Hi David,I'm following up on our last chat conversation regarding your questions about continue to print on a higher position of the code. I talked to my colleagues and unfortunately there is no specific guide or recommendation for it except for printing the missing part and gluying. You can play with the code, but we don't take any responsibility if it fails or damages the printer.Have a good day

The startup routine is too complex for me to figure out what to do without any risk of damaging the machine.
I would really appreciate if Prusa could give some guideline here. PLEASE!
If not it would be great to hear from professional users with better knowledge of g-code how they solve such issues.

HI All Of You
I do not agree with @prusa team they as developers if they were smart would do it no problem it should work in such a way that you can start the gcode from any height by doing it manually e.g.after resuming you lower the Z so that the head does not hit the model and manually do JOG so that the nozzle is brought to a position 5mm above the table. Then press the button with the command ‘catch Z 0’, after which it is necessary to lower the table below the model and hide the extruder, then enter in the board from which row the printout should start, e.g. 75 and the printer will know where to start at a speed of e.g. 10mm semi the first layer.
I am experimenting with the gpt chat we discuss every move and maybe I can do it today but....
The sad truth is that Joseph Prusa makes money on filaments and generally does not care if it prints out or not so @prusa team will not make such an improvement because less filament will be sold and the more you fail the more filament will be sold, they will do it only when the chinese do it first then they will be forced to do it because it is not rocket sciences
