Issues with setting up an "endless" print
I am trying to set up an endless print where the printer will print the object, bump it with the extruder to automatically eject it out of the front of the printer, and then print the next part in the queue. I have figured out how to append the gcode to do this to the end of the print, but there are two things I haven't been able to figure out how to do:
1) Attach the purge line to the part: The stacked purge lines are causing problems. I want to move the purge line so it becomes a pig tail that merges into the first layer of the part so it can be automatically ejected when the part is finished. But I can't find any slicer settings to control the purge line location?
2) Automatic start of next print: I can stack multiple copies of the print in the queue, but I have to keep hitting "set ready" after the part is ejected. Is there a way to automatically proceed with the next print after the completion of the last job? And I would prefer that the solution not be manually copy/pasting a block of gcode multiple times into a single print file. I have ~100 of these parts that I need to print, they are all slightly different, and in total will take a week to print all of them; copy/pasting the gcode manually into one big file is going to be very hard to do error-free, and take far too long to validate.
The purge line is commented as 'intro line' in the Start G-Code section of Custom G-Code.
Is there a way to automatically proceed with the next print
Not simply.
The only rather outlandish work-around I can come up with would be to add g-code to tap a button outside the bed and have that cut the power and start a timer, then after a pause to let capacitances discharge, reconnect...
Probably better to do your copy into one procedure but make several smaller daily files using about one spool of filament at a time.
Cheerio,
RE:
I think you can Set Ready with M1200 ? I saw something on the forum about that.

RE:
The purge location is in Printer settings, Custom G-code, Start G-code, near the bottom.

RE: Issues with setting up an "endless" print
Making the purge line pigtail into the print body wasn't working, and it was a suboptimal strategy anyway since it just added another post-processing step. However, I managed to find a workaround by positioning the part just +Y of the tab where the purge line is normally purged. Now the ejection of the part reliably scrapes the purge line off of the print bed too. Nice and easy! I ran the print 24 times while I was travelling, and came home to a box full of them on the floor.
However, just adding M1200 to the end of the end G-code is not restarting the print. While I was traveling, I had to click "Set Ready" on Prusa Connect every time, which meant missing out on a lot of print time while sleeping or when I didn't have internet. I really feel like human intervention shouldn't be necessary, and that there should be a way to have the printer automatically "Set Ready" at the end of each job. LarGriff: Thanks for finding that thread! I will take this over there and see if they have an answer, or if there is more needed than just "Add M1200 to the G code"
