Pause print to insert nut/washer
-
Sorry if this is not the proper place to put this. I am still using antient S3D (the devil I know). I have the need to stop a print at layer 11 to insert a fender washer and goggle is not helping me. I have found the code to insert from years ago which worked with antique Marlin but I can not find what I need for the current Duet firmware.
I am fine inserting it directly into the gcode at the start of the layer just need the proper code of a link to the "How To" document I have yet to find. Yes most of the current slicers have this option .. not looking to move to a new slicer yet.
Gee.. just had a novel idea.. just paste in the code from the pause button script.. testing now.. NOPE.. -
@airscapes I think M226 is what you're looking for: https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m226-synchronous-pause

@airscapes
apopos to nothing.. I've been doing this for some parts with good success (I manually pause the machine at the appropriate moment.. small parts..)I have found it helps to pre-warm these metal washers on the printbed, before dropping in with tweezers while hot. Seems to help once the next layer goes down on top of it, if cold they can lift and snag the nozzle.

I was making some small desktop speaker stands and wanted them to have some weight. Instead of washers I decided to use some sand. I paused the printed, poured in some sand, and resumed the job. The part cooling fan proceeded to blow dust and sand everywhere. I had added a solid layer to seal the sand layer in so it only happened on that layer, but what a mess. If I were to do it again I would probably use some hair spray or something to act as a binder. Maybe even some PVA glue

@Phaedrux .... or turn the part cooling fan off during the first layer
My next job that requires weight is actually going to be done with sand and I will try to remember to turn the fan off. -
@EasyTarget That is what I have been doing and yes it works fine but one needs to baby sit the layer to stop. I will revisit this at a later time when I have more time to experiment. I did try the M226 but the other code must have messed things up as it did not work as expected.. think I probably need to use M226 with some way to wait x number of second before doing the code to resume.. Clicking the button to resume after M226 does not work as it did in Octoprint years ago. If I remember from what I had read and tired to understand.. M25 and M226 do the same thing but one is for data coming from the SD card gcode and the other the Gui?? Anyway, thanks everyone for the ideas and insight into your own experiences!
Also I found that coating the top of the washer with glue stick and heating it as was suggested worked best. I was using TPU so probably the easiest to get to stick...
