Endstop Z don’t work on BTT SKR-v1.4 Turbo #483

Open Esla2 opened 3 years ago

Esla2 commented 3 years ago

Hi All, You are my last chance, I spend days to resolve that. I put this board into my old 3D( Malyan M180). I wired all the connections. However, I fail on Z Endstop. He don’t want to work. The others endstop(X, Y) work fine. But Z don’t. He stay ‘Open’ and when I home the Z the bed crash the nozzle. When I swap connectors Y and Z it’s work. The endstops on X and Y Are Mechanic, Z is not the same. I ad pic chowing the swap Y and Z ( Y stay open, Z triggered). And Config.h and adv.h Is there a work around ? Sorry for my English, It’s not my native language. And thank you for your help. EndstopZ 1 image config.zip

Hi Redek8 Thank you for your help. The two Youtubes, I seen them already. But they didn’t help me. Because my board don’t work even with endstop mechanic. Now I think my board is defective. I spend a week trying, without result. Now I’m facing, two possibility: The board is made before february Or the Z channel is defective ( endstop Z and andstop mecanic : Two differents Endstop don't work) In addition, the Fan0 don’t work too. I’m going to see that with Aliexpress.

radek8 commented 3 years ago

endstop Z remap to another connector. You can remap Fan0 to HE1.

Esla2 commented 3 years ago

I use HE1 for a second hotend. I already tryed remap Endstop Z without succes.

Esla2 commented 3 years ago

Hi Redek8, Happy New Year. Sorry for my last comment. I was upset about my board. For remap endstop Z I tried this : https://www.reddit.com/r/BIGTREETECH/comments/ewfqn0/skr_14_turbo_inductive_sensor_not_workinghelp/ Without success. In the post, its talk about switch X and Z but they don’t talk how! If you know how could you please tell how to do it. Moreover, thank you for your help.

radek8 commented 3 years ago

A small recap. You are using an optical probe on the Z axis. does not switch when connected to the Z-STOP connector, but works well when connected to the X-STOP. Am I correct?

radek8 commented 3 years ago

Connect the optical probe to the X-stop connector. Connect mechanical endstops to Y-stop and Z-stop. Make sure no endstop is activated and send an M119 command. Activate all endstops and resend M119. Write me both results. This will test whether the optical endstop is on or off by default. We will set the configuration accordingly.

Esla2 commented 3 years ago

No, I’m not using optical probe. Just standard endstop. X, Y mechanical endstop, Z optical Endstop, you can see it in my first Pic. endstop_report

radek8 commented 3 years ago

No, I’m not using optical probe. Just standard endstop. X, Y mechanical endstop, Z optical Endstop, you can see it in my first Pic.

OK, I spoke badly. According to the response M119, it seems that the bird stop does not work even after connecting to the X-axis connector. The optical stop does not seem to work well.

The Z-STOP input works well. The problem will not be on the board but in the optical sensor

Esla2 commented 3 years ago

it was my first deduction, but I changed it with this one and it still doesn't work https://www.amazon.fr/gp/product/B077X8XL56/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Endstop_Amazon

radek8 commented 3 years ago

The problem will be in the sensors. Can you measure the voltage on the signal pin in the activated and deactivated state?

Esla2 commented 3 years ago

With the stock one the value don't change always = 0.01V With the second one( Amazon) Triggered = 0.36V ; Open = 0.17V

radek8 commented 3 years ago

It is bad. are you connected correctly?

radek8 commented 3 years ago

the difference between closed and open must be according to the 3.3V logic. high ≥ 2.0V low ≤ 0.8V

radek8 commented 3 years ago

connected V = 5V G= GND S= Signal pin

Esla2 commented 3 years ago

Yes my connection est correct. my connection check twice. and measured 3 times. V = 5V G= GND S= Signal pin Yes correct. I have betwine V and G = 4.95V

radek8 commented 3 years ago

The voltage between G and S must be in the range high ≥ 2.0 low ≤ 0.8 depending on whether it is closed or open. Is the LED on and off when turned on?

Esla2 commented 3 years ago

The led stay on all the time.

radek8 commented 3 years ago

Esla2 commented 3 years ago

Yes, mine is always on triggered or not.

radek8 commented 3 years ago

Then you have a problem with the sensor

Esla2 commented 3 years ago

My sensor is like yours. and i bay it from Amazon Three days ago.

Esla2 commented 3 years ago

Triggered Open That imply my sensor is faulty. all i have to do is buying others. thank you very much for your help. We can close this thread. Esla2

radek8 commented 3 years ago

Don't buy a new sensor. Buy 3DTouch. It's super

Esla2 commented 3 years ago

have you any brand to advice me ? What i have seen in Config.h it's to tricky to configure !

I bought this and it works great. I wouldn't want a printer without leveling. Configuration is not complicated.

radek8 commented 3 years ago

The malfunctioning fan, remap the fan pin and use the external MOFSET module

Esla2 commented 3 years ago

Thank you for the link to 3DTouch and MOFSET Module. For remap Fan0, with what pin. I use HE1. They are pin 1.26, 1.25 or 1.0 ( E0DET, E1DET or PWRDET) ?

radek8 commented 3 years ago

Pins 1.25, 1.26 and 1.0 cannot supply the fan directly, so a module with Mofset is needed. If it is a fan on the heatsink, or a fan for the cooling of electronics, which is only to be turned on or off, you can use any free pin. But if you want to regulate the power using PWM control (fiber cooling after extrusion) you have to use a pin that supports PWM control, for example 1.26 (via the Mofset module) Pin PWM support can be found in the CPU documentation

Esla2 commented 3 years ago

I need fan for my two HE0 and HE1 (#define E0_AUTO_FAN_PIN P2_04; #define E1_AUTO_FAN_PIN P2_04). I understand I need a MOFSET to turn them on ( EXTRUDER_AUTO_FAN_TEMPERATURE 50). I have Two fans of 12V linked in series. Logically I connect then into FAN0 but FAN0 is faulty. With MOFSET I have to change the pin in adv.h and in pins_BTT_SKR_common.h if i'm correct ?

radek8 commented 3 years ago

FAN0 (pin2.3) is predefined for fiber cooling and is switched by g-code from the printed file. That's probably why it doesn't sleep at 50 ° C Use pin 1.25 to cool the heat sink

define E0_AUTO_FAN_PIN P1_25

define E1_AUTO_FAN_PIN P1_25

Esla2 commented 3 years ago

All this with the MOFSET that you give the link ? What is the the g-code command too turn it on ?

radek8 commented 3 years ago

With another pin you can control the switching and power of the driver cooling fan

define USE_CONTROLLER_FAN

if ENABLED (USE_CONTROLLER_FAN)

define CONTROLLER_FAN_PIN P1_26 // Set a custom pin for the controller fan

 #define CONTROLLERFAN_SPEED_MIN 0 // (0-255) Minimum speed. (If set below this value the fan is turned off.)

define CONTROLLERFAN_SPEED_ACTIVE 255 // (0-255) Active speed, used when any motor is enabled

define CONTROLLERFAN_SPEED_IDLE 0 // (0-255) Idle speed, used when motors are disabled

define CONTROLLERFAN_IDLE_TIME 60 // (seconds) Extra time to keep the fan running after disabling motors

define CONTROLLER_FAN_EDITABLE // Enable M710 configurable settings

OK, I just have to buy MOSFET and 3DTouch Thank you.

tca72 commented 3 years ago

Hello On SKR V1.4, and probably on sKRV1.4 turbo there is an hardware bug on optical endstop on Z axis. There is a wrong resistor on the board ( Z axis). but on other axis it could work. See videos here: https://www.youtube.com/watch?v=gdecCW3vsIM https://www.youtube.com/watch?v=gdecCW3vsIM

i had the same problem as you, but with an inductive probe it was a configuration.h error, there were some not-obvious changes that had to be made in order for it to work with this board and my printer (tronxy xy2pro)
