For anyone who has this problem in the future my solution was to loosen the screw on top of the touch just a little bit

Again another nightmare for 3d printer users - it took me days to figure it out. My Ender 3 bed was warped in the middle. I got a glass bed, which helped. I installed the BLTouch and used the Ender 3 Pro firmware. It gives you the options in the menu. I also added the G29 code to G-code. But it's not perfect. I needed to manually adjust the Z-probe.

PSU is only feeding 12 V into RAMPS, but (if I remember correctly) RAMPS is using Arduino's onboard regulator for converting 12 V to 5 V. That regulator can not provide much power. If you connect some significant load to any 5 V pin (like servo, LCD backlight, or BLTouch), the regulator will be overloaded and its output voltage will drop (too low or unstable ...

There could be multiple reasons for this happening, the most probable cause would be that the bed isn't leveled properly, if you have an auto leveling bed I'd suggest that you give that a run through, I also found it personally helpful with mine (Ender 5 Plus) that if I did the manual leveling, so the four corners, then go and do the auto leveling. Another ...

Replace the probe The probe that came with the original BLTouch definitely had issues. There seems to be some slight difference in the original probe and was replaced with a spare probe that comes with the Ender 5+. There was an immediate change in success rate of turning on the device and other measurements. This blog post goes into more details. I was ...

Try calibrating your Z offset Based on this answer it sounds like the flashing red means there isn't enough clearance between your bed and your probe for it to operate. You might try raising your Z axis up a bit to let the probe achieve the minimum clearance necessary for deploying the probe. My guess is that your Z-offset isn't quite right and it isn't ...

I have a similar issue. My BLTouch does the 9 point leveling. But if I have not already got the bed level, it doesn't print correctly. It seems like the BLTouch isn't actually doing what it's supposed to do... This is my G-code: Ender 3 Custom Start G-code M117 Getting the bed up to temp! M140 S{material_bed_temperature_layer_0} ; Set Heat Bed temperature ...
