Problems from the second layer to the 7th layer

[carlinicompetizione]

I'm having problems with over extrusion from the second layer to the seventh or so. I've already used avance presion but it doesn't solve the problem, it only makes it worse because it thickens the filling even more.
or from the 7th to the 8th layer, the printing normalizes and in some cases even due to the lack of plastic.
I'm using the filament monitor

@carlinicompetizione please post response to M122 and config.g

I expect you are using bed mesh compensation? Is your bed particularly uneven? If you have bed mesh taper set M376 https://docs.duet3d.com/User_manual/Reference/Gcodes#m376-set-bed-compensation-taper, what layer height are you printing at?

Muito obrigado, não entendo nada de programação, mas acrescentei no config.g essas funções M375 e M376

@carlinicompetizione

Firstly, thank you very much for responding, I have already included the requested information, M122 and config.g
In that same file I added the functions M374 -M375-M376H25, there were no changes, the subsequent layers of the first one have excess plastic for at least 5 years after the first one, then it starts to normalize. I'm very sad because I don't know what to do.

[carlinicompetizione]

Hi Ian, well unfortunately I'm very sad about the board, it should work well. I ask for your attention if possible and if there is any way you can help me. In the first layers, I detected that the table does not go down, it only does this from the 4th layer onwards, which is why it keeps accumulating plastic and stagnating the print. I've tried everything I've been told, I've used several slicers and in every case the same problem occurs. Is there a way to resolve this? via firmware putting the Mxx that helps solve it?, if putting a Rapberry PI 4 does it solve it?

[oliof]

@carlinicompetizione A raspberry pi does not help here. There is some chance that this is not a software, but a hardware issue, i.e. the mechanism raising the nozzle (or lowering the bed) may be binding until it overcomes the early layers.

You could try commanding the printer without issuing a full print, doing moves with the G0 and G1 commands after homing, to see how things behave.

[droftarts]

@carlinicompetizione This sounds more like backlash in the Z axis, or the Z axis is sticking when it changes direction. If you move the bed up, then move it down in small increments, eg 0.1mm, does it move straight away, or only after a few moves? What Z height does DWC report at the beginning of the print, and what height when the bed starts to move? If you can see the Z motors, do they move, but the bed does not?

When you start a print, do you use baby stepping? Is the Z probe calibrated for Z height correctly?

@oliof

So, it's not a mechanical problem, because it makes the home without problems or locks. the printer has large dimensions 400x 700 mm and Nema 17 motors of 0.8 kg/cm2, if there were any blockages the motors would make noise. In fact, they move, correcting the height of the Z of the map throughout the construction of the first layer, when it is finished, it does not change height for the next one and begins to deposit plastic, thickening too much. From the third layer onwards you feel the movement of the z when changing to the next layer.

@droftarts

Yes, I use CR touch to create the map and I placed the M 374-M375 and M376 without success, it looks the same
I use Baby step to get the first layer right, which looks really good. From then on it does another three layers without going down, from the fourth down it goes down normally.

[oliof]

@carlinicompetizione I can hardly imagine that the machine would ignore some Z motion commands and then suddenly respect them again. Maybe share the start of a gcode file up to the layer where things work again?

[carlinicompetizione]

@oliof

I will place a dial indicator on the table and activate the fan on the third layer to check if there is a change in the Z height

[carlinicompetizione]

@droftarts

I've read a forum where this happens, but I lost the link and I can't find anything about it, it gave some instructions to read. If I barely remember, the problem was related to a conflict with self-leveling that removed the first layers from the first.

[carlinicompetizione]

@oliof

In the settings made on the board, there is something wrong or something that could be improved or something that is missing. I know about jerk accelerations to some instruction that is missing for the automatic height adjustment in Z with the CR touch.

[dc42]

@carlinicompetizione have you tried reducing the Z speed and acceleration limits in the M203 and M201 commands? Your Z acceleration value in particular looks high to me.

[droftarts]

@carlinicompetizione

I use Baby step to get the first layer right, which looks really good.

How much do you need to babystep to get the first layer looking good?

Can you post the first 100-200 lines of a Gcode file that causes this problem? Or upload a whole Gcode file somewhere so we can take a look? It's possible the slicer is inserting speed/acceleration/jerk settings that are overriding those set in config.g.

Some errors in your config.g:

; Aguarde um momento para que as placas de expansão CAN iniciem
o G4 S2

Remove the o from the beginning of the line.

M566 X500,00 Y500,00 Z300,00 E1200,00 ; definir alterações instantâneas máximas de velocidade (mm/min)

Do not use commas for decimal point. Use decimal point: .

;M208 X0 Y0 Z0 S1 ; definir mínimos do eixo

You have commented out the M208 minimum, but X0 Y0 Z0 is the default.

Check your config.g is valid by sending M98 P"config.g", and check the response in the console. If there are any errors, please post the response in your reply.
