Printer can’t do anything, no homing, no bed levelling, no printing. Just flashing BLTouch red.
Attempt to Home - Pin can be pushed out but not pulled in. And then Z-axis is raised instead of going down to home.
when printer powered on, same thing, pin pushed out, flashing red light.
I tried to print from laptop via USB cable but stopped just after heating nozzle and bed.
Error M99 - see image below
Any idea how to address this trouble / error message? Please, advise or suggest possible solutions.
Try disconnecting the BL touch and see if that fixes the problem. If it does then there is something wrong with the Touch or it just isn’t playing nice with the motherboard. If not then it could be several things bad motherboard, firmware, broken wires etc.

sounds like a wiring issue.

I cant confirm this exact error, but i find i need to “reset” my bl touch sometimes.
Is the bl touch flashing when this error occurs?
Yes, the BLTouch is flashing red. How to reset it? Where to find reset instructions?
Is there a way to test the hardware? I could simply buy and replace with a new 1 but that does not help if problem is anywhereelse (motherboard, wiring, etc…)

Thanks, did this a few times but still did not work. Even removed probe and checked for filament debris or other potential blockages but still no luck.

check if the probe is still straight if you haven’t already. a tiny bend can get it stuck and it’ll time out trying to retract

Probe looks straight. it goes in and out quite easily with a light/gentle push or pull. No apparent issue there.

One other thing that happened on mine when it was new. After a couple months I had to screw the set screw in a tiny bit more and never had a problem with it again after that. I had tried everything else and still had an intermittent problem wit it erroring out.

I tried so many things (list below) with this error and I am not sure what exactly finally fixed the problem. Thank you for all suggestions - The problem is partially fixed and now I can print. When I turn on printer sometimes the bltouch does its self-test, sometimes, it does not. My hack: if does not work, turn off printer, wait 10 - 20 seconds, push bltouch probe inside, turn on printer = success. (Note sure why but if probe out when i turn printer ON, selftest fails: just flashing red light).
Trial and error List:
- Check/fix wire connections
- Remove set screw, remove probe and clean inside as needed.
- Reassemble, adjust screw to flush with the plastic, reinstall on printer
- With probe out, turn on printer, if self-test fails, go to (5)
- Turn off printer, wait 10 - 20 sec, push probe inside and try again. if this too fails, try to screw in or out the set screw by 45/90/135 degrees (less than 180).
- My case worked (at lest, partially) by screwing in approximately 90 degrees.
Note: If turn on printer with probe in - works 100% of time. If probe out, it may/may not work (not sure why. May be Hall sensor, or coil magnetic field sensitivity). At least now i know. Voila! Thank you!

Im away from my printer (cr10s pro) and i have some custom firmware on it from tiny machine. But they had it as a option (the bl touch reset). Id say look into a flashing bl touch fixes and see what comes up.
Im overtired right now but if you mention the printers particulars (model, control board version, and firmware version installed) ill look into it tonight and try to get back to you.
The printer is Creality CR-10 Max (original, unmodified, cura 1.1.6)

Hi, just received the cr10 max with bltouch and it took a full 24 hrs to get it to print. I wanted to share what was necessary to do, it might save someone a bit of time. After manually leveling per instructions then going through the auto level sequence, I attempted to auto home to try a print. The probe deployed twice and then lowered the nozzle into the print bed creating a deep indentation. After checking the probe, resetting the probe set screw and rechecking all wiring connections, I was running out of ideas. It would repeatedly drill the nozzle into the bed. After searching MANY forums, videos and Facebook groups my wife came across the answer. The z offset was way off, set to -13.The solution: I attempted a print, went to the adjust screen, and zeroed the offset(I had to do this twice, once it warms up the screen changes). The next auto level was well above print bed, and I was able to adjust it once again. The second issue was the supplied SD card was faulty. I added my own file and attempted to print it with no luck, same with the supplied g-code files. Luckily I had a spare card from my ender 3 and it worked fine (as long as the filename is 11 characters or less). I use PrusaSlicer. One last thing. During my first successful print I changed the z offset live while printing, I could tell the first layer didn’t have enough squish, it ended up being -2.10. Hope this helps.
