Description

On Auto-Home (and also via moving menu) the Z-Axis does not move back down anymore without the Z-EndStop. With the EndStop switch plugged in it does move down.

Steps to reproduce

Replaced the old original board with the new SKR mini E3 V3.0
Installed the BL Touch Smart v3.1
Removed the original Z-EndStop switch.
Installed the Firmware: firmware-ender3-bltouch-for-z-homing.bin
Press Auto-Home

Expected behavior Z-Axis should move down also without the EndStop with firmware-ender3-bltouch-for-z-homing.bin. And Auto-Home should success.

Actual behavior Z-Axies does not move down on Auto-Home or even over the moving menu. For example set moving +10mm the Z-Axis is moving up, then set back to 0 nothing happens without the EntStop plugged in.

install te previous version firmware, problem should be solved

hieblmedia commented 2 years ago

Thx for the hint. Tried all previous precompiled files. The only one works is the first version from 2 month ago, so far on an quick test. https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/a3076873ab0b34e1e33d44e56bc86c861c7e3432/firmware/V3.0/Marlin/firmware-bltouch-for-z-homing.bin

In the meantime have also tried to compile the firmware myself and had the same issue. Now, I am wondering - Is it a problem with Marlin or somthing wrong in the config file.

Hansd007 commented 2 years ago

Why is @bigtreetech not responding on this issue. They should already know there is a problem?

leventuri commented 2 years ago

I had the same problem. After almost frying my E3V3 board, I could solve the problem changing the sensing wires from Z-PROBE slot to the Z-STOP slot. It seams that we have some problem on PC14 pin in the last Marlin code. -Venturi-

P.S.: I'm using the last "firmware-ender3-bltouch-for-z-homing.bin".

mistic100 commented 2 years ago

Unless I am mistaken "firmware-ender3-bltouch.bin:" should be used if the BlTouch sensor pin is connected to Z-PROBE, and "firmware-ender3-bltouch-for-z-homing.bin" should be used if the BlTouch is connected to Z-STOP.

I installed my V3 yesterday with "firmware-ender3-bltouch-for-z-homing.bin" and using Z-STOP, works perfectly.
(used this configuration because my 3DTouch wire has 3-dupont + 2-JST connectors and I didn't want to change it)

bmgermann commented 2 years ago

I have a similar problem. I installed the firmware-ender3bltouch.bin, and installed the BLTouch to the Z-Probe. However, it worked once correctly, creating a mesh for the plate. After that, however, the probe would only move to the first point and not descend to measure the height of the plate. The printer would then report an error with the BLTouch when it deployed and did not make contact with the plate.

LazeMSS commented 2 years ago

I have the same problems with both V2 and V3 card: https://github.com/MarlinFirmware/Marlin/issues/23395

LazeMSS commented 2 years ago

@bigtreetech could you look into this - I will be happy to provide further debuggin - it also seems like linear advance is not working for the SKR e3 mini v3 and neither is pin debugging.

LazeMSS commented 2 years ago

And does this work?

JakeTheDawgg commented 2 years ago

yes bugfix file labeled for ender-3 on display works with bl touch and no zstop. https://github.com/Seelenkind/BIGTREETECH-SKR-mini-E3.git

what is different in that config vs BTT config? i definetly liked that UI better.

Favmir commented 2 years ago

I spent the entire yesterday trying to figure out what was wrong with my new setup, narrowed it down to the BTT firmware not being able to handle zprobe port input — unlike the original Crealty firmware, the zstop port has to be physically plugged in or the printer would freeze from G28 or G29 command with M112 error(fails when it tries to go down with the probe out). Tried both firmware-ender3-bltouch.bin and firmware-ender3-bltouch-for-z-homing.bin, and neither works without a zstop plugged in. firmware-ender3-bltouch.bin needs BOTH the zstop and bltouch, and firmware-ender3-bltouch-for-z-homing.bin needs to be plugged in via 2 connectors(one of which goes into zstop socket, no idea where the other one goes) instead of the dedicated bltouch port.

EduMota commented 2 years ago

I'm having the same issue, do someone knows whats the different between current firmware and that version? I really wants to make more changes on firmware.

MavrEars commented 2 years ago

Have the same issue. Tried my own compiled firmware with this FAQ: https://www.makenprint.uk/3d-printing/3d-firmware-guides/marlin/consolidated-marlin-guide/ But after UPDATE to Marlin bugfix 2.0.x it do the PROBE an MESH but when starting to print stuck with error "Printer Halted Please RESET" UPDATE!: Managed that problem was in power loss restore It need to be like that:

define POWER_LOSS_RECOVERY

if ENABLED(POWER_LOSS_RECOVERY)

#define PLR_ENABLED_DEFAULT   false // Power Loss Recovery enabled by default. (Set with 'M413 Sn' & M500)
//#define BACKUP_POWER_SUPPLY         // Backup power / UPS to move the steppers on power loss
//#define POWER_LOSS_ZRAISE       2   // (mm) Z axis raise on resume (on power loss with UPS)
//#define POWER_LOSS_PIN         44 // Pin to detect power loss. Set to -1 to disable default pin on boards without module.
//#define POWER_LOSS_STATE     HIGH   // State of pin indicating power loss
//#define POWER_LOSS_PULLUP           // Set pullup / pulldown as appropriate for your sensor
//#define POWER_LOSS_PULLDOWN
//#define POWER_LOSS_PURGE_LEN   20   // (mm) Length of filament to purge on resume
//#define POWER_LOSS_RETRACT_LEN 10   // (mm) Length of filament to retract on fail. Requires backup power.

// Without a POWER_LOSS_PIN the following option helps reduce wear on the SD card,
// especially with "vase mode" printing. Set too high and vases cannot be continued.
#define POWER_LOSS_MIN_Z_CHANGE 0.05 // (mm) Minimum Z change before saving power-loss data

NOW everything is working! ENDER 3 PRO CR TOUCH (OR BL TOUCH) + SKR mini E3 v3 + Marlin bugfix 2.0.x Here is the link: ENDER 3 PRO BTT SKR MINI E3 V3.0 CRTOUCH MARLIN 2.0.x.bin.zip

nofate301 commented 2 years ago

@MavrEars Thank you! Holy crap, I was going nuts about this and finally yours worked.

ruralTom commented 2 years ago

Because they already have your money. Each of these boards has been plagued with issues that only get resolved by issuing a new version of the board. Stop doing business with them.

creggerj commented 2 years ago

I just got this working. had the same issue for a long time.

In all my findings I believe its something to do with safe homing and probing not enabled in the firmware. No sources... It tooke me a while before I was able to make anything work .

My next venture is getting my DWIN display from an ender V2 to work with this.

austinprimo commented 2 years ago

new to 3d printing does this have filament runout sensor enabled?

Russ48 commented 2 years ago

Found that I had to plug in the Z stop to get consistency in the Z position using BLTOUCH.. regardless of what Marlin setting.

OOPS Failed again when trying to do Bed Leveling with the BLTouch

morencyam commented 2 years ago

Your firmware solved my issue as well. Is there any chance you have the associated config files as well? There are a few other changed I'd like to make as well.

rvsuper8 commented 2 years ago

Yes config files please.

jrgleason commented 2 years ago

I can confirm that the image worked for me when the others didn't as well

jrgleason commented 2 years ago

Ok I tried to recreate what you are doing but I am still having issues. Using the config here (https://github.com/bigtreetech/Marlin/tree/SKR-mini-E3-V3.0-G0B1) I tried changing the following...

// Configuration.h

...
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
...
#define BLTOUCH
...
#define Z_SAFE_HOMING
...

// Configuration_adv.h
  ...
  #define POWER_LOSS_RECOVERY
  #if ENABLED(POWER_LOSS_RECOVERY)
    #define PLR_ENABLED_DEFAULT   false // Power Loss Recovery enabled by default. (Set with 'M413 Sn' & M500)
    //#define BACKUP_POWER_SUPPLY       // Backup power / UPS to move the steppers on power loss
    //#define POWER_LOSS_ZRAISE       2 // (mm) Z axis raise on resume (on power loss with UPS)
    //#define POWER_LOSS_PIN         44 // Pin to detect power loss. Set to -1 to disable default pin on boards without module.
    //#define POWER_LOSS_STATE     HIGH // State of pin indicating power loss
    //#define POWER_LOSS_PULLUP         // Set pullup / pulldown as appropriate for your sensor
    //#define POWER_LOSS_PULLDOWN
    //#define POWER_LOSS_PURGE_LEN   20 // (mm) Length of filament to purge on resume
    //#define POWER_LOSS_RETRACT_LEN 10 // (mm) Length of filament to retract on fail. Requires backup power.

    // Without a POWER_LOSS_PIN the following option helps reduce wear on the SD card,
    // especially with "vase mode" printing. Set too high and vases cannot be continued.
    #define POWER_LOSS_MIN_Z_CHANGE 0.05 // (mm) Minimum Z change before saving power-loss data

    // Enable if Z homing is needed for proper recovery. 99.9% of the time this should be disabled!
    //#define POWER_LOSS_RECOVER_ZHOME
    #if ENABLED(POWER_LOSS_RECOVER_ZHOME)
      //#define POWER_LOSS_ZHOME_POS { 0, 0 } // Safe XY position to home Z while avoiding objects on the bed
    #endif
  #endif

But I am still getting the behavior where it doesn't move in the z axis. Again the above linked image does work but because I am using a different hotend and mount it goes off the bed when I try to center so I need to get the config and rebuild.

shawnpetros commented 2 years ago

so...just installed this firmware, but octoprint is not connecting to my printer. Is there a jumper I need to add or does the firmware need to be updated to allow serial over usb? Kind of lost here since all I wanted to do was add auto bed leveling to my E3P, and it required a mainboard + firmware compiling and it's been sort of a nightmare so far.

dartarien01 commented 2 years ago

Thank you so much!! I spent hours looking for a fix, probably clicked on at least 40 videos and subreddits etc, your firmware fixed my issue immediately! I made an account just so I could thank you and let others know it worked!!!

LaddiusMaximus commented 2 years ago

Ive tried all the fixes here but I still cant home my z axis or use my bl touch. Has anyone made any progress on this?

nofate301 commented 2 years ago

Double check everything.

Make sure you're using the right board, the right cr touch. Check all your connections.

Test your axis and make sure the right axis moves when you test.

Check your plugs are properly oriented.

Seriously, it sounds like something is either catastrophically wrong with the board or a step is being missed.

Are you sure you're flashing the firmware correctly? You've renamed the file to firmware.bin and it's at the root of the card? Your memory card is good? Have you tested any other memory cards? Remember the card can't be too big and it's formatted correctly?

So I went back and checked everything. It turns out I did not follow the pinout as closely as I thought I had. My zstop pins were reversed which after correcting, everything is now working as it should. Thanks for the heads up. I now have to make sure my filament sensor is working so you may hear from me again. lol

Meatyhog commented 1 year ago

I'm very new to 3d printing. I've spent hours trying to get my skr mini e3 to work with bltouc z homing on my ender 3. I am having the same issues as above. It looks like the problem has been solved for the Ender 3 Pro. Will that software work for the standard ender 3?

LaddiusMaximus commented 1 year ago

I think so? But aurora tech had the fix here: https://youtu.be/dtwWnz2-5VQ

Not my version, but you are quite welcome. Glad it helped.

Hi, I've got the same issue but only after upgrading to Marlin 2.1.2. On version 2.1.1 everything worked as intended. I've compared the configuration.h and conf_adv.h from both versions with their counterparts and everything should be the same.

I'd try the version here but I'm not using an Ender3. Did you guys make any notable changes to Marlin but the ones regarding power loss? I've tried these but it doesn't solve the problem. Also like I mentioned it worked on version 2.1.1 with other power loss settings so maybe something else is the reason for it.

Some general information that might be helpful: Anycubic Mega SE SKR mini E3 V3 BLTouch Clone (3dTouch I think) Z endstop not connected to the motherboard use_zmin_plug not defined in marlin

I've noticed that while USE_ZMIN_PLUG is defined the Z axis does move down when you are inside the move axis menu however it still does not when homing. While USE_ZMIN_PLUG is not defined it doesn't move in either scenario.

Edit: What do you guys get from M119? for me the z_probe is always in "triggered" state indicating something is wrong according to marlin website. If I understand it correctly the printer won't allow Z to go down when the state of the probe is triggered.

SocalS4 commented 1 year ago

Hello, Just wondering if you eve got Octoprint to connect. This is the only firmware that allows my E3P to auto home correctly. I have compiled many different versions and have had the serial connection working through the USB to Octoprint but cant get the auto homing to work without using @MavrEars Version. Does anyone have a decompiles version that is working with Bltouch that i can compare? Or a list of changes needed for the compile to work? THNAKS

kentonbmax commented 1 year ago

How did you get past this? I have same issue.

SocalS4 commented 1 year ago

I ended up having a compile my own firmware from scratch many many times until I figured out the problems. And there were tons of them. If you'd like, I can try to find a way to upload the firmware bin file and it will probably work for you.

Jbrizuel12 commented 7 months ago

you're firmware fixed my issue also I know this is an older thread. But, im just now getting into 3d printing. How do you get the z axis to go into negative again? this was something I was able to do before I installed the new motherboard and firmware, but can no longer do.
