I've decided to use the 3DClippy tool to avoid the tip shaping all together, but I need some help with the G-Code. I've used the G-Code generator for Mode 3 and I have the code, but in the code itself it says this line:
; <<<< insert mechanical cutter code here! >>>>
What cutter code do I use for this? My X axis is used for my switch at the limit at 235 and that was configured by the generator. I am using a regular Ender 3 Pro. Any help would be really appreciated.
Well, it really depends on your particular machine. When you install the 3DClippy, you need to adapt it (and the code) to your particular installation. In general, you need to add the code at that point that moves the X axis over to one side to trigger the cut, and then back to the other side (like a G28 X to home it) to reset it.
Our sample code on the Ender 3 V2 can be used as a guide on how we implemented it for that particular machine. You can see it here: https://www.youtube.com/watch?v=BBzq4Lhg4Jc
The Ender 3 V2 profile is in the description of the video. But here is the relavant section. Notice the cool "hack" used to increase the motor torque and slow down the cutting action... and then also notice the homing to reset it afterwards. ; go to holding position to unload the stock extruder
G0 X220 Y227 F2000 ; Â <<----- Â EDIT THIS LINE TO SET THE INITIAL LOCATION OF THE BUTTON
G91 ; set motions to relative for the button presses
M92 X8; set x steps per mm to a small value (very high torque)
G92 X0 ; set to 0 so we have a lot of room to travel
; cut off the filament tip
G0 X310 F10000 ; quickly cut the filament strings off
G0 X-310 F10000 ; ok... go back to normal position
M92 X80; restore x steps per mm to normal value
G92 X220 ; restore original position
G0 E-2 F2000 ; pull filament off blade (this will pull off the tip if it didn't cut all the way through)
G0 Y-10 F2000; move away from clips
G28 X; home the x axis to reset the position
G0 X0;
G0 Y10 F2000
; push off tip into ptfe tube
G0 E5 F10000
G0 E-7 F10000
; retract it back out of the extruder
G0 E-100 F10000
G0 E-40 F10000 ; total backout of 250mm
; ok - out of extruder - press button to remove it all the way
