Ender 5 plus trigger switch position

Im wondering where the best place to put the trigger switch is on the ender 5 setup. I have it mocked up in place in the front right corner. im trying to place it off the build area to keep as much build surface as possible. This setup would keep is so the only way the button could be triggered is intentionally. My issue is this, the position of the switch would be a negative coordinate. But when i tried to set minimum for that stepper motor with Sonic pad it wont let me set negative values. I wondering if i can make my max bed size 360 or so on that axis in order to move the "0" point farther away? or is there a better place to mount the sensor? im not 100 percent sure on the best place to mount it without it being triggered accidently during bed mesh or printing. Thanks so much. Ive got pretty much everything else ready to test at this point so hopefully this can get me going this weekend

I'm confused as to what you're talking about... the Sprite Extruder is a hotend as well, so there shouldn't be any long distances at all... The only distance you need to deal with is the distance between the Sprite's drive gears and the nozzle tip... which is only about 65mm or so.

The distance should never involve the Y adapter... that's the timing one, which you have as 30.6 seconds.

when talking about the y adapter, i was referencing how i got to the 30.6 second estimate hoping to verify that was correct. My other question was about the E75 command. i was asking for a roiugh estimate of the distance that could be used but you answered that in your responce sayingf about 65mm. So i would change my E75 to E65 in the above G code? everything else looks correct to you? Sorry im still not very versed in g code commands

Does this seem correct? im going to switch over to Bambu slicer as im using for my X1C and want to have it correct before i copy it over. thanks bill

So I do have the creality silent board installed currently. To be honest though I'm not really sure what you mean about setting up a spare I/O. I've had to relocate my front crossmember due to the sprite extruder so I also wouldn't be able to mount it there. I've moved it to 0.5 on the y which seems to work and I don't see it getting in the way of any homing or abl calculations so im hoping this will suffice

If you're using a Creality main board still, then you can actually set it up to use a spare I/O instead of using a physical switch. Green wire goes to the signal pin from the board, and black goes to a ground. But if you still want the switch, then you can literally place it anywhere... all you need to do is tell the gcode generator where on the X or Y axis it is. The Ender 5 can have it at the front along the X axis (Y all the way to the front, regardless of what that value is) anywhere that is convenient.

That way it's in a specific spot on the X and Y axis only and not necessarily only on one axis.

Yes, that's correct. The S15 parameter is the one you need to adjust... so that the extruder's drive gears start spinning right before the filament reaches them... that way they're both working together to insert the filament.

Optionally, you can replace the S15 with P15000 (P = milliseconds) to get a more exact time delay. The E75 in the next line tell is how far to load into the extruder to get to the nozzle... you want to tune this so that the filament stops just before reaching the nozzle exit... that way it resume printing in the purge instead of creating a blob outside it before it reaches the purge block.

press the button to select the new extruder
G0 Y-3 F2000 ; press the button
{if next_extruder==0}
G4 P500 ; dwell for .5 seconds - adjust this to match your machines single pulse time
{endif}
{if next_extruder==1}
G4 P1000 ; dwell for 1.0 seconds - adjust this to match your machines two pulse time
{endif}
{if next_extruder==2}
G4 P1500 ; dwell for 1.5 seconds - adjust this to match your machines three pulse time
{endif}
{if next_extruder==3}
G4 P2000 ; dwell for 2.0 seconds - adjust this to match your machines four pulse time
{endif}
G0  Y3 ; back off the button

G0 Y-3

G4 S30.6 ; delay 30.6 seconds while the previous filament unloads

M400

G0 Y3


G4 S1 ; wait for the color to change


G0 Y-3

G4 S31.6 ; delay 31.6 seconds while new filament loads

M400

G0 Y3

G4 S30.6; wait for it to happen ; adjust this time to match the actual tool change time - subtract the time it takes to load for the last 1" into the extruder
G0 E75 F1500 ;      << -------   ADJUST THE E50 VALUE TO STOP IT RIGHT AFTER IT LOADS INTO THE STOCK EXTRUDER (50mm is the default)
;                ADJUST THE F1500 TO MATCH THE SPEED OF THE FILAMENT FROM THE 3D CHAMELEON
;                NOTE: This defaults should work, but you can always tune them to be perfect.
G4 P1500 ;          This is just a half second extra reloading time... just to make sure
G92 E0

So this would be correct for my tool change other than the E75 line? Im running the sprite extruder, im unsure how long the throat tube distance would be. is there an esitmate for that I could use? I measured with a piece of filament, 778mm from the stop of the sprite extruder, where you would have to hit the release lever to go further, to the middle of the second "Y" on the chameleon. Thanks Bill, I appreciate the help this is really my first time trying to "modify" g code

any help with this would be very appreciated. I'm still struggling to get this setup so i can even test the machine. thanks bill
