Pause Print Directly After First Layer Skirt - G-code

[Joecool3]

Hey all, hope everyone had a Merry Christmas

I’m trying to add a custom g-code string that will pause my print for 30 seconds or so after laying down the one-layer-thick skirt that circles 4mm offset from a print’s base. I’d like to add this so that I have 30 seconds to apply glue along the inside of the skirt on the bed, ensuring that I know exactly where the corners and edges are going to end up in a print, so that I can minimize warping etc.

I have almost no experience jacking 'round with g-codes, so if you can give me any suggestions, that’d be great!

Alternatively, I am looking at other types of adhesives for printing ABS on low-temp glass (85C, Because right now my printer is limited to only that). Right now I just use a large Elmer’s Glue glue-stick, and my prints stick well, but I have to apply more glue after just about every print. Is there another relatively inexpensive brand or type of glue, or any suggested hairsprays, that can take several prints before needing to re-apply?

Thanks again,

Just apply the glue to a larger area before printing

That’s a fair reply, but I’m having trouble keeping sure that the corners are actually contacting the glue, therefore causing warping. Often I’ll cover the whole area and miss a section (due to the difficulty of applying a uniform coat of glue with a glue stick). Also don’t like having to cover a large section with glue anyway, as it wastes a lot more, and unfortunately I only really get one good print per coat of glue; in general after about a day, sections that haven’t been printed on loose their grip. I’m about to try hairspray and see how things fare.

*If* you can find the place in the gcode where you want to pause the printer, you can insert something like this…

M117 Pausing print ; Displays this message
M600 X10 Y15 Z10 ; Pause printing and move to: X:10, Y:15 and Z:+10 from current

M117 Filament Change Complete ; Displays this message

In theory, your printer will pause, move the head where you told it, and then wait until you un-pause it, then start from where it left off. How to do that depends on your machine and whatever interface you use. (That’s the vague part.)

Thanks a lot, that’s really helpful.
