Had a question. I did everything correctly and have the Dual steppers going. I'm having a hard time leveling the bed manually. I screwed the four corners up as you stated, I heated everything up, did the Z axis auto align (worked great). However, I'm used to the button on the Ender Plus stock board for AUX leveling, just using a piece of paper to fine tune places on the bed. I can't seem to find a setting like that on this Marlin build. The closet thing is the leveling of the 4 corners and that doesn't help because I can get the front of the board up towards the nozzle (using the screw knobs), but the back of the board is maxed out. The ABL function is off, I feel like manually leveling is the better way to go. What do you think I'm doing incorrectly? Edited: looks like what I’m looking for is bed mesh leveling (points on the bed, paper under nozzle, turn knob to move the Z axis to fine tune each point) and the G28 command disables the mesh bed leveling..

Hey Kersey, thanks again for your help it's working on my ENDER5 Plus, so I tried to put it on my CR10S5, the bltouch is probing on left side then on the middle of my bed, not on the right as it's supposed to (my bed size is 510x510) I didn't changed the Z_STEPPER_ALIGN_XY so it was supposed to use the bed probe limits, any idea?

Nice, going to do this too 👍

I am liking this change, after playing with it a bit, along with the Bed Visualizer plugin to octoprint I have a bed that is consistently nearly all green zone after probing. I did notice one thing about the firmware compile you did, however. The G34 probing and the mesh probing is unbalanced. The probe deploys MUCH closer to the right edge than the left edge.

Your videos are all great! I have almost the exact same setup and I'm very grateful that you provide the compiled files! One question I have is do you already have the bltouch offset adjusted to your hydra fan setup? Or is it setup for stock offsets? Thank you!

Hi ! Great footage ! BUT ! The head is not moving simmetrical from the mid point. How to set this up ? What means the line: Z_STEPPER_ALIGN_XY with the coordinates ? If i change the coordinates I get an error when compiling "point 1 is not reachable"... So hiw to change the coordinates to place the head to the most end of the bed on both sides ?

I received my dual z-axis kit a couple of days ago and fortunately found this video while searching for instructions, so a big thank you from a new subscriber! I say fortunately, because the instructions I was looking for dealt with keeping the gantry level when both steppers were on the same driver (short answer: manually level every time your z-axis steppers are powered down). My new mainboard w/5 stepper drivers will be here in a couple of days. On a semi-related matter, what do you think about getting rid of the bed springs? I've had some run-to-run consistency problems (if I don't manually level the bed before *each and every* print) on my orange-spring equipped Ender 3, even with a BL-Touch and UBL. I've seen several suggestions to replace the bed springs with solid spacers, to eliminate the bed as a variable. I asked one of the folks who suggested this how much difference it made, and was told it made a significant difference.

@kerseyfabs

3 жыл бұрын

I'm glad the video was helpful. I don't recommend removing the screws unless you plan to add at least a 3-point bed leveling system. Otherwise, I don't know how you'll level it in one direction. That doesn't mean that people can't make it work but you end up depending on auto bed leveling more than I would. To make the spring as reliable as possible, make sure you compress them as much as possible and work from there. I usually compress all the way then raise it up 3-5 turns.

@@kerseyfabs As a proof-of-concept I cranked the springs all the way down and added a couple of thick washers to raise the bed above the z-axis physical limit. That resulted in significantly more consistent meshes, so I ordered 100 M4 washers and installed the same number on each corner, after which my bed was nearly 2mm our of alignment. Using my calipers, I sorted them into groups with 0.05mm deviation. I found thicknesses from 0.75mm to over 1mm (all from the same lot, mind you), and that was the problem. My new main board was delayed (thanks, Amazon!) and should be here tomorrow - let the fun begin! I'll be relying on my BL-Touch and mechanical limit switches going forward (or perhaps replacing my glass bed and going back to springs?).

I had a quick question. My Z motors only had a "Z" tag on both and not a "Z1 / Z2". I imagine it matters which goes to which side otherwise how would it know which side it is adjusting? Do you know (if looking at the printer head on) which motor is 1 or 2. ie left is one and right is 2 or vice versa. Thanks for the videos and firmware by the way they have been a major help.

Hello, great video, unfortunately I'm not able to get G34 function working, I have CR10S with V2.2 board which has extra E1 driver so it should be able to work as Z2. I set up everything in Marlin just like you showed in the video except for number of Z steppers (that line is missing in latest version of Marlin) and when I try to compile FW it shows me this error "TMC2208 or TMC2209 on Z2 requires Z2_HARDWARE_SERIAL or Z2_SERIAL_(RX|TX)_PIN." Is there any chance that you would know what am I missing there please? Thank you for answer :)

Hi Kersey. Have you had any issues with G34 making a mess of the Z offset I have found occasionally it gets it out of wack , I had the situation again today ran G34 then auto homed, then set a print running and found the nozzle was closer by around 1mm than it was on the last print which I didn’t use G34 Any clues

Hey Kersey, thank you so much for all of this, I learned a lot ! Everything is working great but I think the probe offsets on your "Dual Z-Axis Firmware" are for your fan duct (X -52, Y -20, Z -3). I'm using the stock hotend/fan so when I auto-home, the BL touch is not at the center of my bed, I can change the probe offsets on my advanced settings menu, do you know what are the value for the stock hotend?

Hey I'm on the latest version of marlin and I'm not seeing the # of z stepper motors in the adv config. I'm assume it's now calculatng it based on what motors you enable? I using 2 motors and uncommented z2 in the config. My issue is that no matter how I set the settings under auto align, it always probes 3 spots on the bed: middle left, middle, and bottom center roughly. I tried the manual coordinates and only had 2 sets of coords listed, yet it STILL probed 3 locations on the bed. It doesn't make sense. I just want it to probe the left and right side of the bed like it shows in the example. Do you know what's wrong?

Does it matter which of the left or right Z-stepper motors goes to which port on the board? More specifically the E3 Turbo board. I didn't see an answer in this video, or your E3 Turbo install video.

Great video I was waiting for something like this. I have tried to do it on my core xy tronxy x5sa Pro printer with skr 1.4 turbo and TMC 2209 and after updating the firmware I go to try the z axis movement in increments of 0,1mm and 1mm for safety and they do a grinding noise every time they move. I can home X and Y ok but no Z. When I home Z something very strange happens they start moving in sincro at least they appear to me but after 2, 3 seconds the right motor Z1 move down more steps than the left Z2 motor causing the bed to warp so I guess that is the cause of the noise. What may be causing this? I have connected the right motor (z1) to ZMA connection of skr 1.4 turbo and left motor (z2) to E1M. I don’t use sensor less homing so I’m using physical x and y endstops. I have tried to change up the current until 800 but no change. I don’t know what else to do. I guess that the cause of only being able to move in one direction may be because until it does an auto home and triggers the inductive sensor its always at 0. Looking at pins skr 1.4 section I can find #define E1_STEP_PIN P1_15 #define E1_DIR_PIN P1_14 #define E1_ENABLE_PIN P1_16 #ifndef E1_CS_PIN #define E1_CS_PIN P1_01 I have tried to change the E1 for Z2 but to no avail… here you can find my marlin files so you can see all the configuration. I was using one driver (connecting the motors to ZAM and ZBM)to move the two motors until now without problems but having an extra tmc 2209 driver I wanted to try this. mega.nz/file/DeIxBaSR#xZCH0mTVW_rQuZlErJrHpVbGzRnkrhGXpNizqBP3BUU Greetings.

Is there a simple way of just editing the firmware I'm using at the moment and enable the G34 portion, set it up on the board with the heatsink and it be good to go, theoretically? lmao

What you're asking for is theoretically possible, just as you described it. Unfortunately though, that's a V2.0 feature and I'd have to port all of the Creality special code (for the display) from this release to the new tree. That's just not something I have time for at the moment. Sorry I can't help out.

This technically should work using the alignment and bed leveling BUT it's not a good idea. Bed leveling is meant to compensate for bed deformation and slight variation in height. It is not meant to 'level' the bed. It will compensate for the bed being off level but that could show up as skew in your prints if it's too far off level. I still recommend manually leveling first.

I am not sure I understand why mesh bed leveling cannot fully compensate for a tilted gantry. Wouldn't it just look like a tilted bed, compensate, and print normally?

This is a fantastic function and I like that you brought this to the public eye. I would really like to use this on my E5+, but after multiple attempts to update with the .Bin file that you had graciously given to use, I cant load it. after a whole lot of searching forums, I have concluded that I have dropped my bootloader somehow. I have an E5+ with an SKR 1.4 Turbo and a TFT35. Sound familiar? I have purchased an Arduino UNO R3 and a ATMEL 51 AVR USB ISP ASP because that's what others have used. After reviewing the info that I had gotten my ideas from, I found that noone else was using the SKR 1.4 turbo, and it seems to be completely different. I thought I could figure it out but I've begun to realize that I'm out of my league. PLEASE HELP!!!!!

hello sir. thanks alot for your help. i have afew question and please help me becuase i really need to know this. 1- We use "z step auto align" to apply equal pressure on the motors? And some motors do not carry more weight? 2- if we have quad z stepers, we have to uncomment this 5:57? define z_stepper_align_known_stepper_position 3- could you please tell me what is this: "z_stepper_align_known_stepper_position", i didn't understand it in video. 4- in marlin commented this: "requires triple stepper drivers" ......for quad stepper drivers we also have to use this "define z_stepper_align_known_stepper_position"??? Thanks alot for your help. looking forward to see your answer. thanks alot. good luck! :)

@kerseyfabs

3 жыл бұрын

To be honest, I've never heard of that one. Are you running one of my firmware or is this something custom?

While auto-align is a nice feature, with 2mm lead and POM-nuts you mostly will not have any disalignment anyway, so it is a bit of overkill. Also the mechanic is not made for independend positions for both z-axis. It is staticly over-determinated. It works only by using tolerances of the mechanical parts. Any system with autoalign should be constructed with a staticaly determinated system. Much more interesting is auto-align with 3 steppers. Of course a bit of redesign of the z-mechanic is needed to move it by 3 leadscrews alowing the bed to be be adjusted )make the system staticaly determinated). But the printer would get real auto bed leveling, so no more manual bed leveling.

@@greggcaplan1304 I got one of the SKR E3 Turbos to solve this problem. It has 5 stepper drivers and was the least expensive path from my (nearly new) Mini E3 V2. Note that the Turbo's 5th stepper is designated for a 2nd extruder but Marlin (apparently) automatically remaps it to the 2nd z stepper if you set: #define NUM_Z_STEPPER_DRIVERS 2 and #define Z_STEPPER_AUTO_ALIGN // if you want G34 to work! in Configuration_adv.h. I say 'apparently' because, while the code builds without unpleasant messages from SanityCheck.h, my printer is still apart for mechanical tuning...compensating for a warped heater plate as well as a the carrier plate upon which it rides. I got this printer to build parts and enclosures for hobby projects, so I want the best dimensional accuracy I can get. I love my Ender 3 V2, and if I can get it printing as well as it's more expensive competitors I'm willing to put in the work.

I tried this for the first time on my E5+ with SKR E3 Turbo. I get a read out at the end that says 1:2=0.697. So it's telling me that the left and the right are still out of alignment by 0.7mm. I repeated it multiple times and it gives me the same error. Tells me the z align algorithm isn't working right. It is using the two points showed in your video. I'm using a different firmware, so I'm blaming that for the time being unless I can gain a new understanding or I have time to dig through the sourcecode to see exactly what it is trying to do. I watch the screen and it seems to dance around the value, so it's not making small enough choices in trying to adjust the position of the z steppers. It is varying them, but it's playing "love me" "love me not" type games instead of getting closer. I only share this in case anyone had a similar experience. I'm using TM3D firmware. Interestingly enough, after a while I decided to just move the z axis rods independently by sight and feel. I was able to get it within 0.04mm by manually adjusting them and rerunning the G34 after that.
