I would like my printer to prime a little more before it starts printing. Anyone know which setting does this? Basically the head is homed, it moves up slightly, primes and then moves to it’s starting point for printing. I would just like it to prime slightly more. Also, if you know of any other cool code to add to the start or end I would appreciate that as well. My printer is an Anet E10 if that really matters. Only a couple of minor mods but nothing that should affect any of the settings below. Also, the below settings are the stock ones from Cura.
In the start Gcode line G1 F200 E3 change E3 to a bigger number.
G1 F200 E3, E3 means extrude 3mm before printing, increase it as you need.
If you retract more at the end (you probably need 10-20mm, depending on your hot end), you’ll be able to swap filament between prints without heating up the hot end to release it. Of course, if you do that, you have to account for it in your priming at the beginning.
@Sonex128 That’s kinda what I thought it was but I wasn’t sure if the 200 maybe meant nano meters because not much comes out. The printer I use at work extrudes a lot more and it allows the plastic to be dragged along just before it starts printing. This basically moves the primed filament out of the way so they don’t get tangled up or stuck to the hot end. I’ll give it a shot and see what happens. Thanks for the info.
F200 is the feed rate. E3 is the extruder distance in mm. It may not extrude all of it due to ooze. My a8 oozes terribly.
I set mine to 15 so it makes a little pile in the corner and doesn’t drag it over into the print. G1 F200 E15
The other one I add in, if not already there, is G1 Y250 F3000 to the end code just before turning off the steppers (M84) so it moves the bed forward at the end of the print. Presents your print to you. The value after Y needs to match or be slightly less than your printable dimension in Y. 250 is for a 10" deep bed.
I generally use a skirt as a priming for the print.
@Jeff_Parish I do something similar on my printrbot except I can use G28 Y0
@Thomas_Cox Yep. I use the G28 X0 Y0 to home mine and then the G1 Y250 to move it forward in Y. I guess it depends on where your bed is homed from. My 0,0 point is front left corner.
@Jeff_Parish The printrbot moves the bed in x and the head gantry in Y. So there is no need to x0 then move the gantry back out. It also seems most stable with the bed centered in x. Your move looks great on any i3 clones.
