Every time I print, I need to increase baby steps

[TimsWorkshop]

@phaedrux thanks for the response mate and looking into it.
I've got an EZABL and I used this article to set it up and set my offset.

It's roughly the same amount, 0.06 - 0.08, but it varies.
I did run a G29 earlier and I've got a height map, but not sure if I'm loading it or not... I think it's in the bed.g file G29 ; probe the bed and enable compensation

Yes, but are you ever using G32 to run bed.g? I don't see it in any of your start code.

I would suggest that you update your firmware to 3.3 by uploading this zip file to the system tab in DWC
https://github.com/Duet3D/RepRapFirmware/releases/download/3.3/Duet2and3Firmware-3.3.zip

Re measure your G31 Z offset with nozzle and bed at temp.

Test your homeall again by seeing if the nozzle just touches the bed at Z0.

Then re-level your bed and send G29 S0 to create a fresh heightmap.

Then add G29 S1 to your slicer start gcode after the G28

Make sure your extruder flow rate is calibrated and then try a test print of this file to test how well the mesh is working.

@phaedrux

Thanks mate, I will give this all a go now

[TimsWorkshop]

@phaedrux

Thanks for this! I've done the upgrade and reconfig... Z-offset is set to 1.750, G31 P500 X47 Y10 Z1.750

When I did the first print of the suggested file, I had to babystep to -0.33
On the second print, I had to again babystep to -0.45

On the third print, I had to again babystpe to -0.66

On all three prints, when I am facing the printer:

• the right side of the bed prints very low to the bed and the filament is almost squished.
• but on the left sidem, it prints very high and the filament barely sticks.
• In the middle, it's also still pretty lose

This is my height map, after configuring the z-offset, after levelling and this looks pretty bad and I've had better.

It's also good to point out that I don't yet have a LCD screen, I've ordered one but it's two weeks late or lost, so I am doing everything via DWC.

When I level the bed, I jog the hotend to where my 4 bed levelling screws are and I use a sheet of paper to get them all having the same resistence when I pull on the paper and then I check centre again.
After I do this, I run the G29 S0.

Also, I still don't see a mesh.g file... am I supposed to have one of these?

@infidelprops

Hi,

Since you have a Z probe you can get some help adjusting those bed leveling screws.

Manual Bed Leveling

Basically the firmware will move to each of the 4 locations you specify and probe the bed. Then it will compute the adjustment needed for the 2nd, 3rd, and 4th leveling screws. It uses the 1st point as a reference and screw isn't adjusted.

It works well.

@infidelprops

Hi again.

The G32 command executes the bed.g file and that file you must create and populate with the needed commands.

The G29 command executes a mesh.g file, if it exists, and again that file you must create and populate with the needed commands.

---

I put in each file all of the needed commands to insure that I can execute a G32 or G29 command and have the process complete successfully without having to be sure to do certain other commands first.

This can lead to a bit of inefficiency as you may be doing a few of the same commands in each file. But given the time each process takes any extra time due to the duplicated commands is minimal.

---

I also should mention that the DWC is already setup to invoke G32 or G29 from a pull down menu so if you stick with creating bed.g and mesh.g then you can invoke those processes from the DWC without errors.

Frederick

[TimsWorkshop]

@fcwilt & @Phaedrux thanks for the explanations!

I've tried this previously, but I wasn't doing it right and I've now put them in the right file, but when select True Bed Levelling (G32) within DWC, I get the below message after it homes z, but the hotend doesn't move anywhere:

@infidelprops

Hi,

You recall that I said I put all commands needed into each file so the will execute successfully without any other steps being taken first?

Now having the M671 in config.g works. But you may find you need to change those values because they are not quite right. If you put the M671 in bed.g then anytime bed.g is executed the current values in the M671 command will be used.

---

Now as to why it is not working for you. In your G30 command you are using Z-500.

Read this from the G30 documentation:

G30 with a P parameter

This is used for operations that are performed after the printer has been homed and that require the height error at more than one probe point to be measured. These operations are typically performed in the bed.g file. With a Z parameter of -9999 or less, the head moves to the specified XY coordinates and the dive height (set using the H parameter in the M558 command), and probes the bed.

---

Also since bed.g is intended for bed leveling (auto or manual) and mesh.g is intended for creating the height map needed for mesh bed compensation I would not include the G29 in bed.g. They do not need to be done together and if you included G29 in bed.g you cannot do them separately.

For example I implemented auto bed leveling on one of my printers. I level the bed when I home it. But I only create the height map manually using a DWC Macro as the height map can usually be created once and used over and over. I load the height map use G29 S1 in the code which is executed at the start of a print.

---

One thing you do need to add to your bed.g file is the code to set the Z=0 Datum using a G30 command. I always set the Z=0 Datum using the center of the bed for the XY position that you must always set before executing the G30. You use a normal G1 command but you have to compute the X and Y parameters so the probe is positioned at the center of the bed and not the nozzle. This means you have to take into account the X and Y offsets of your Z probe.

---

Frederick

[TimsWorkshop]

@fcwilt thanks for the details!

I've updated bed.g with the following, but not sure if I'm setting Z=0 correctly. Based on reading the documentation for G30, what I'm doing is:

• Move Probe to centre of bed
• Use G30 to probe the current location
• Then move and probe the screw locations and probe

@infidelprops

I made a mistake.

It's quite late here and I overlooked the fact that you are doing manual bed leveling so setting the Z=0 datum would have to be done after you completed the manual process.

Sorry about that.

Now that I know how much to adjust it... what's the best way to adjust the knobs given they're a manual turn? And do I still need to run a G29 as well to get a height map or this a 1 or the other situation?

Now that I know how much to adjust it... what's the best way to adjust the knobs given they're a manual turn? And do I still need to run a G29 as well to get a height map or this a 1 or the other situation?

I find it difficult to turn the adjustment screws the amounts specified - like 0.14 of a turn. After awhile you just get a feel for it but it can still take many tries. I strive for perfect but I'll settle for being off by 0.01mm.

Now I may just be inept but I find my printer with just 3 adjustment screws much easier to get right than the one that as 4 adjustment screws.

With my manual adjust beds I check them periodically with G32 to see if they have changed.

With my auto adjust beds I do that as part of homing Z.

I create the height map periodically if I think something may have changed. If you implement mesh.g you can create the height map via the DWC pull down menu, via a DWC Macro or just by executing G29.

I load the existing height map in my print start code.

the basic steps related to leveling and mesh compensation are:

• home the printer
• level the bed if auto bed leveling is implemented
• set the Z=0 Datum
• load the height map

Of course I do others things in my print start code like set the bed/extruder temps, wait for them to reach temp, prime the extruder, etc.

Frederick

[TimsWorkshop]

@fcwilt thanks! I actually got some sleep last night and this morning I realised that I just need to turn the knob slightly, then re-run the test again... so the coffee did it's work this morning.

For the G29, I have an empty Mesh file now, and when I run G29 it does nothing... should I put the following in my mesh.g file?

mesh.g

M561 ; clear any bed transform
G28 Z; home   
M557 X90:400 Y15:360 P20 
G28 Z; home

For the G29, I have an empty Mesh file now, and when I run G29 it does nothing... should I put the following in my mesh.g file?

Below are the essential commands from my mesh.g file.

Now I make use of many separate files dedicated to a specific function.

Below you can see M98 invocations of probe_config.g and probe_set_z.g. The comments below say what they do.

You can of course configure the probe in config.g as many folks do and you can set the Z=0 Datum using a G1 command and a G30 command.

But since these two processes (configuring the probe and setting the Z=0 Datum) need to be done in several other places I create dedicated files for such processes to be invoked with M98 as needed.

M98 P"probe_config.g"             ; configure Z probe
 
M98 P"probe_set_z.g"              ; set Z=0 datum
 
M557 X-140:140 Y-125:140 P20:20   ; define 400 point mesh
 
G29 S0                            ; do probing and save height map

If you have questions please ask.

Frederick

[TimsWorkshop]

@fcwilt Thanks man, really appreciate it!

I've got the manual adjustments done now and reporting back 0.00 for all but one screw, so I'm OK with that for now. I've updated mesh.g to include the below and it's creating the height map now.

;mesh g - manually configured
 
M98 P"probe_config.g"
 
M561 ; clear any bed transform
G28 Z; home  
 
M557 X90:400 Y15:360 P20 ; define probe area and points
G29 S0 ; probe and save height map

I've also setup a probe_config.g file as I do like the seperation of files, and in here I have:

; probe_config.g
 
; Z-Probe
M558 P5 C"!zprobe.in" H3 F650 T12000 	; setup my EZABL
G31 P500 X47 Y10 Z1.750  		; set Z probe trigger value, offset and trigger height

Can I see what you have in your probe_set_z.g file? I've seen multiple post from you around setting Z=0 Datum, and would like to see what you have in there so I can read the gcode doco and figure out what's going on. Question: Will setting this help me to stop having to re-do my babysteps every time I turn my printer back ok? (IE: When I print, as indicated above, I'm constantly updating baby steps, even for the same layer height, but when I turn off my printer and back on... my baby steps go back to 0.00 and i need to reset it as when my first print starts, it's a good .5 mm off the bed)

[fcwilt]

@infidelprops

Forgot.

Once you set the Z Trigger Height correct (and it seems you have) setting baby stepping will not be needed every time you print.

I still find myself tweaking the starting Z height when printing if it looks like the first layer is not quite right.

Thanks, making more sense and I will take you up on the offer to see the homeALL_verify.g, center_probe.g and your config.g file?

And nah, I don't get confused... it makes more sense to me as a developer. (more on the JS/Node side than this/perl)

Here are the files. I cleaned them up a bit removing experimental stuff. I hope I didn't break anything doing that.
