bed mesh result weird... is this normal? #139

Open tjengbudi opened 5 months ago

tjengbudi commented 5 months ago

after install bd sensor and place mesh bed for 30 point to check i got strange result. is this normal? klipper mesh

markniu commented 5 months ago

yes, this looks strange. are the heightmap almost the same for each bed mesh? could you paste some data here from the console?

tjengbudi commented 5 months ago

suddenly the bd sensor cannot response. i do not why. now i event cannot get Z HOME... check it first and confirm after will report you

tjengbudi commented 5 months ago

@markniu i check the cable and change the SDA to used EXP1 port and it still cannot receive any data. what i must to do?

markniu commented 5 months ago

Both the SCL and SDA pins are changed to EXP1? make sure the 2 GND wires are connected to the mainboard

tjengbudi commented 5 months ago

the scl still used probe/servos pin. i checked with m119 the z always open i put metal and the light in the bdsensor's led is on, but m119 return z still open

M102 S-2 always return " BDsensor:Out of measure Range or too close to the bed"

markniu commented 5 months ago

Calibrate again

tjengbudi commented 5 months ago

how to calibrate. i cannot homing for Z. it never detect my bed. and crash after i homing. force manual?

tjengbudi commented 5 months ago

Calibrate again

BDsensor is too far from the bed:1015

markniu commented 5 months ago

how to calibrate. i cannot homing for Z. it never detect my bed. and crash after i homing. force manual?

yes ,use the manual and SET_KINEMATIC_POSITION , M102 S-6

markniu commented 5 months ago

and then check the data after M102 S-5

yes ,use the manual and SET_KINEMATIC_POSITION , M102 S-6

after i send M102 S-6 i got BDsensor is too far from the bed:1015

after i send M102 S-5 i got

markniu commented 5 months ago

the data looks right. btw the led on represent that it is in the measure range but not mean it is triggered for the z axis

tjengbudi commented 5 months ago

and now it suddenly "BDsensor is too far from the bed:1015" again

markniu commented 5 months ago

you can comment out the no_stop_probe in the section BDsensor, and send M102 S-2 to check the actual distance after it stopped by that error

tjengbudi commented 5 months ago

after some touch here and touch there... it is working again. check cable with multitester. it is connected ok

after plug again and test it is run but the result is amaizing

klipper 2

M102 S-2 fave result "0.42mm"

markniu commented 5 months ago

is the data returned by M102 S-2 almost the same after very G28
G1 Z1
M102 S-2

tjengbudi commented 5 months ago

after idle... it stop working again... frustrated what happened with this sensor

it crash after i sent g28

tjengbudi commented 5 months ago

tjengbudi commented 5 months ago

trying check and meassure without changing the height at all

it can changing by him self from 0.99 --> 1.03 -->0.44

tjengbudi commented 5 months ago

must i reflash it ?

markniu commented 5 months ago

I suspend that there is a hardware problem maybe the cable EMI from other wires. where and when do you purchase this v1.1 . I would like to send you a new one, you can send me your shipping address to my email niujl123@sina.com

markniu commented 5 months ago

did the hotend heat? if the hotend too close it maybe heat the coil

it can changing by him self from 0.99 --> 1.03 -->0.44

tjengbudi commented 5 months ago
