the lerdge endstops are meant for 3.3v but should also work in 5v mode
post the changes you did in the config
-
@Veti i used this config:
M574 X2 S1 P"!io1.in" ; configure active-high endstop for high end on X via pin !io1.in M574 Y1 S1 P"!io0.in" ; configure active-high endstop for low end on Y via pin !io0.inShould i connect with the additional resistors like it is mentioned in the dozuki
3.3V-compatible optical endstop Connect Gnd to Gnd, Vcc of the opto sensor to 3V3, and the output of the opto sensor to STP/IN. Opto sensors usually have active high outputs, so use S1 in the M574 command. Note: opto endstops made to the Generation 7 design are often claimed to be 3.3V-compatible, but in fact the design is marginal with a 5V supply and frequently doesn't work at all on 3.3V. Here are some workarounds: - This design normally works with a 3.3V supply if you replace the 180 ohm opto switch series resistor resistor by 100 ohms. Tip: if your opto endswitch uses surface mount resistors, instead of removing the 180 ohm resistor it is easier to solder a 200 or 220 ohm resistor on top of it, so that the two resistors are connected in parallel. Make sure you pick the correct resistor to replace or solder another on top of! There is often also a load resistor, value 1K or higher. - If you are using Duet 3 then you can use the 5V pin on the IO_ connector to provide power to the opto endstop instead of using 3.3V power. - If you are using a Duet WiFi/Ethernet hardware rev 1.04 or later or a Duet Maestro, these boards can tolerate 5V on the endstop inputs. So you can provide them with a 5V supply instead (leaving the centre pin of the endstop connector not connected) and connect the outputs of your endstops directly to the STP/IN pins of the endstop connectors. -
i run the endstops fine on my delta without resistors. the lerdge endstops are actually designed for 3.3v because the lerdge board run on 3.3v
check with m119 if you can trigger them.

maybe a bad crimp in the cable?
-
@Veti the led on the switch is on , but it doesent trigger
-
@Frederik
it could be a bad crimp in the signal wire -
@Frederik
the advantage of the lerdge endstops is they light up when they are triggered. the ramps endstops light up when they are not -
@Veti one moment , i will check it a second time
-
@Veti you were right
I tested it with the original cable and it triggers .....yeah...thank younow both the ramps and lerdge are functioning
