[Feature Request] Print prime line in the front side of plate instead of on the back

[BambuLabDiscord]

Currently an L-shaped prime line is laid down in the back of the plate. This line is hard to remove without taking the plate off the bed. Printing a prime line in the front in the same area where the extrusion calibration lines are will make it possible to pick up everything from a textured PEI plate after the print is finished, without having to take it off the bed. This small change not only will make the plate cleanup easier but also helps to keep the ABL data reusable longer (at least for the same filament).

you can change the start gcode to accomplish this yourself, if you think its a good idea then learn the gcode like we all did and figure it out, here's a hint, G1 is the motor, Y265 is spot 265 on the Y axis

[Benderrodrigu3z]

it should be around the last couple lines of code in that, you could copy it all then remove the lines until that line purge line is removed and then copy them back

It might be this: G0 Y128 E6.4 G0 X252.5 G0 Y252.5 E6.4 G0 X128 E6.4

E means extrude this amount just make sure that the movement is the same amount, if the line is 3 inches keep it 3 inches when you move it else you will get extrusion issues

In regards to the above work around: I would really like to hear what bambu has to say about this. I would like to see them consider and weigh the issue, and perhaps provide the solution to a larger audience. While a work around for a single individual makes sense, it would be great to see the product improve and the user experience improve with it. This is not a forum for people to discuss tricks, it is a place to communicate with the devs about features, problems and potential solutions they maybe are unaware of. Consider posting comments on Discord and such, and consider that people on GitHub are contributors. This particular response of yours appears to be made in good faith (after the edit), but it's not as much about the OP's personal problems as a suggestion to the devs to improve the user experience.

On topic: I've always thought they should add a little tab on the second/third layers to make the end of the prime line easier to pick off the bed as well. I often find myself removing the plate to lift the line in the back, or unduly stressing the z-mechanisms trying to get the line off. I'm suggesting the tab at the end of the line as an alternative approach to solving the issue you mentioned. [Edit: Add picture]

I'd strongly recommend to incorporate a new check button in Bambu Studio (e.g. in Quality setup) to let user decide whether he/she wants to print prime lines or not. Prime lines are not friendly to plate, since they are printed on the same place again and again. And if user forgets to remove them, it may cause printer damage. I am used to use skirts for nozzle purging, prime lines are really really annoying me.

[GuzziRaz]

Agreed. I assume there is a reason for not only a prime line in front (even with calibration turned off) but also one at the back, instead of just defaulting to a skirt that will never be in the way. But what it would be?

[kibinek]

Well, I have solved the issue with unwanted prime lines here :)

You can remove them it’s in start gcodeSincerely,Shane FSent from my iPhone13On Nov 28, 2023, at 11:32 PM, kibinek @.***> wrote: I'd strongly recommend to incorporate a new check button in Bambu Studio (e.g. in Quality setup) to let user decide whether he/she wants to print prime lines or not.
