I would like to add a piece of code to my slicing software (beginning code) and I am not sure how to do it properly. What I want to do is add a line to print before the actual print starts. I want to do this so that the nozzle is fully primed before starting. I can get the position right and extrude some filament, but the filament comes out in one go and then the line is drawn without the extruder pushing out more filament. So what I need to know is how to draw a line, say 100mm long and deposit some filament down while it is drawing the line. I want to add this code to all files before they start the actual print, so I would need to add it at the beginning code section. Anyone know how this is done? https://reprap.org/forum/read.php?1,312810,312810#msg-312810 Wed, 14 Oct 2026 16:17:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,312810,312929#msg-312929 https://reprap.org/forum/read.php?1,312810,312929#msg-312929 Many small items that are being printed together I like to put on a raft so that they don't come loose and then I loose the lot.]]> regpye General Wed, 19 Feb 2014 06:26:56 -0500 https://reprap.org/forum/read.php?1,312810,312848#msg-312848 https://reprap.org/forum/read.php?1,312810,312848#msg-312848 brnrd General Wed, 19 Feb 2014 01:27:07 -0500 https://reprap.org/forum/read.php?1,312810,312836#msg-312836 https://reprap.org/forum/read.php?1,312810,312836#msg-312836 I have auto bed leveling and the nozzle always starts at the front right hand side.
I can take the nozzle down to the bed no problem, and then move the nozzle 100mm to the left before it starts to do the print.
I would like it to extrude some filament on the way. I tried to send some filament out just before the 100mm move, however the filament comes out and then the nozzle moves.
What is happening at present with the prints is that the first few centimeters sometimes don't have any filament extruding when starting to print. If doing a perimeter around a print that is not so much of a problem, but if doing a raft it can mess up the raft where the perimeter is missing.]]> regpye General Wed, 19 Feb 2014 00:08:22 -0500 https://reprap.org/forum/read.php?1,312810,312834#msg-312834 https://reprap.org/forum/read.php?1,312810,312834#msg-312834 Edit: maybe i miss understood.. was my suggestion what you were asking how to do it?]]> cat.farmer General Tue, 18 Feb 2014 23:58:24 -0500 https://reprap.org/forum/read.php?1,312810,312810#msg-312810 https://reprap.org/forum/read.php?1,312810,312810#msg-312810 What I want to do is add a line to print before the actual print starts.
