        @Phaedrux its a glass bes with a black material on it. i can throw a piece of white paper on it to see if it makes a difference.

            Consistently? Does that make sense given the thickness of the glass? assuming the black is on the back side?

              @Phaedrux im new to this but i dont think so. i thought when we got it level in the middle and sent that code it told the probe where 0 is? shouldnt that be where it stops then?

                Post your homing files and bed.g.

                When you do the G30 S-1 procedure to measure the trigger height, is it consistent now?

                    Your homing file is configured to use the Z endstop instead of the probe.

                    So in homeall/homez you'd want to replace this part:

                    @agent0810 said in New IR z probe issues:

                    ;G1 H1 Z305 F360 ; move Z up stopping at the endstop
                    G1 H1 Z-320 F360 ; move Z stopping at the endstop
                    G90 ; absolute positioning

                    with something like this

                    G90 ; absolute positioning
                    G1 X150 Y150 F6000 ; move probe to center of bed
                    G30 ; probe the bed

                      @Phaedrux Changed as requested, and same result. do i need to move the mount holding my probe up a bit?

                        Maybe? I haven't seen how you have it mounted and even then I'm not an expert on the IR probe. Maybe post a photo?

                        Also check the lens of the sensor to see if it's dirty or bent or something. It can be cleaned with a cotton bud and IPA.

                          would a BL touch be a better route?

                            Well the IR sensor should be a good choice, I'm just not sure what's really going on. Can you provide some more details on the setup as it is now so we can figure out if it's a configuration issues, or an issue with the probe itself. We'll try and cover our bases first.

                            Post your config.g as it is right now. Confirm you're running fw 3.1.1 by sending M115. Also send M98 P"config.g" and post the results.

                            Post a photo of your probe as mounted and a close up of it. Also maybe the wiring at the board.

                                That mount seems to put it at a bit of an angle?

                                  yea the mount isnt the best but the best i can find right now. ive stood there and pushed it level and made sure it is. i make sure it is for tests, but same results. right now when i home/or print it runs the nozzle on the glass bed so nothing comes out.

                                    Your trigger height in G31 is still the default 2.5. Your measured amount was closer to 1.7ish, so you need to update that. The trigger height would be more consistent if the mount was improved.

                                    It is triggering now though right?

                                      so when i do home all it goes up to the nozzle then back down a bit, then i do the G30 S-1 and it goes up to almost where i need it to be, so close. but still needs to go up a bit more. i have gone through the page alot and changed the offset and trigger heights with no luck. i tried at 1.7, 5, and now im at 0, all put it at the same place.

                                        @agent0810 said in New IR z probe issues:

                                        Sorry this doesn't make any sense to me.

                                        Are you following the instructions on jogging the nozzle to touch the bed, sending G92 Z0, raising the nozzle a bit and then sending G30 S-1? That should give you a trigger height. You then put that trigger height value into the G31 Z. Then after rebooting and homing you should be able to have Z0 just touch the bed.

                                          Doing everything you say there, except instead of raising the nozzle i am lowering the bed. that is what has me confused, from everything im doing i feel like i should be getting the results i want.\

                                          and to be clear, what i put in G31 Z is the output on the console right?

                                          thanks again
