BLTouch not really working

@modl can you home Y and then send M558 and post the output?

modl

M558
Z Probe 0: type 9, input pin io4.in, output pin nil, dive height 5.0mm, probe speeds 120,120mm/min, travel speed 6000mm/min, recovery time 0.20 sec, heaters normal, max taps 1, max diff 0.03

After homing Y

M558
Z Probe 0: type 9, input pin io4.in, output pin nil, dive height 5.0mm, probe speeds 120,120mm/min, travel speed 6000mm/min, recovery time 0.20 sec, heaters normal, max taps 1, max diff 0.03

@jay_s_uk I found the culprit !! I actually had an extruder wired the wrong way when i first powered the machine, I rewired it as soon as i found out but it's been getting really hot even if idle since then. I unplugged it from the board and the probing now works. How to know if the stepper is cooked ?

Thank you very much for all your replies and your guidance

modl

Hope i didn't cook the driver...

jay_s_uk

@modl glad you found the culprit! if it gets very hot even when not in use thats not a very good sign at all. is RRF generating any warnings?

modl

@jay_s_uk No RRF doesn't ring. I tested the coils resistance though one is .4 ohms the other is 4.8. I guess this one's cooked. Any way to know how the driver is doing except plugging in an other axis an changing config.g?

jay_s_uk

@modl thats probably the easiest way to test the driver. Thats the way i usually test drivers

modl

@jay_s_uk OK I'll try that. Again thank you very much!

modl

It was actually pretty fast, and the driver is doing fine

jay_s_uk

@modl fantastic!
