@oliof no applozies needed

@rexx it depends where the endstops are and if you can physically pass them by. also depends on the length of you trigger leg if you actually need to pass them by. Without more detailed photos of your printer I'll probably give misleading answers.

@oliof
good day,
the travel is there the oem setup allowed bump past the stop i have about an inch and only need .5" to tap the abl retract away but at the stop switch its not enough to complete the retract probe tap completely the printer was duel material and nozzzles and now only one so i have extra room

it also may make more simplicity to simply chop the trigger tab down .5" where any home would retract the probe if it was deployed when homing then i only need deploy.g i think...
and i would need to home in a way it goes to the back center (outside the bed) then x's homed as the tabs and slider are to be hit from the side to side not back to front

for deploy similar just the other sides tab but first must be somewhere in the middle of x then to the back not to catch on an angle but side to side for the ABL use only.

when just the x stop is hit can it go 13mm more in that direction being told in the code for only x stop?

@oliof

i will snap a pic soon for you getting close with the wiring

for my abl optical switch if i use a 10k resistor across 5v and gnd guys said series resistor is that diffrent or just the way its wired?

are they directional a typical resistor?

sorry for all the school questions...

the head is back in the machine and its not gonna ever print single wall print with only supports at 2000% (the oem limitations no wall line counts 1 only no turning off supports N/A no raft N/A to revome either the sparse or 100% infil option only is pure sponcership)
now just dont crash it... stay tuned

hamlin 0404 (59085-040)
hey good day
the two wire hamlin switchs are magnetic so A.picture is how they will go correct?

does my opto 4 wire need to be wired like B pic or C picture for use as probe trigger

alankilian

@rexx The schematic in picture "B: is incorrect.

The pullup resistor should be between "+VCC" and "S signal" like it is in picture "C".

I don't understand your question about B vs. C so I can't help with that.

Optical switch :as for the resistor i have 180 ohm 2W resistors 330 ohm 1W resistors 10K 1/2W

i think i should use 5V side with 330 ohm /1w would this be fine?
do i need 2 or just one i have found two diffrent ways the PCB shows 2...

question: does a 222 resistor and 101 come in an inline form how do you find the impedances to replicate or do you know what the values are for them OR do you think mounting this board remote is a better route

Yes, 222 is a 2.2Kohm resistor and 101 is a 100 ohm resistor - except that it looks to me that the marking is actually 181 which makes it a 180 ohm resistor.

The 180 ohm resistor sets the current of the IR LED in the opto switch. The 2K2 resistor is a pullup resistor on the output. Its value is less critical, so your 10K resistor should work OK instead.
