Problems from the second layer to the 7th layer
-
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:

In the Gcode output, you are using absolute mode for extrusion; we recommend relative mode (M83)

Also, this line is wrong for RepRapFirmware. This is a Marlin command.

I can't see anything else obviously wrong with the Gcode file. It should not changing the motor settings in config.g. It does have some Z movements at maximum speed, so you should try moving the bed at these speeds; try sending the following:

Ian, thank you very much for the guidance, I did as you suggested,
The M208 is actually deactivated, I activated it. The Z tests with perfect F8000 drops 25 5 without any problems! When I send the command G29 S3 and G29 S1 there is an error reading the map and I cannot load it. I'm going to change the CURA configuration to RRPP even today it is with Marlin, but in config.g the command is as M83. -
It may be that the Map is not loading, I need to add some command to the config. g to load and activate the created map?
-
@carlinicompetizione
Check the grid spacing in M557 that doesn't make sense to me.
You have only defined 4 points in the grid. -
@carlinicompetizione said in Problems from the second layer to the 7th layer:
I need to add some command to the config. g to load and activate the created map?
There are several ways to do this.
I have added it to my homing routine.
But it also works at the end of the config.g. However, you must definitely call G29 before printing.
There are also several options for G29. I only load the saved map.
If the printer is stable, the mesh does not need to be recreated each time. -
@carlinicompetizione No, you certainly shouldn't save the map in config.g, as no map is in use; I'm not exactly sure what this does, but most likely creates a blank map, hence the 'invalid grid' error.
Also, you shouldn't load a map during config.g, because you have not homed the Z axis to set the Z datum point.I've just remembered you mentioned putting M374 and M375 in config.g, please remove these. They are synonymous with G29 S3 then G29 S1. M376 is okay.
You should home Z, then load the map or run the mesh bed scan, then home Z again. That will give the most reliable results from a saved mesh. You can do this in homez.g, homeall.g, in the start.g of the slicer, or create the file sys/mesh.g, which is run when G29 is sent. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#g29-mesh-bed-probe and https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_mesh_bed
But I don't think this is related to the problem of your machine not moving for the second layer, though you could try a test without mesh bed levelling enabled.

Having activated the M208 seems to have solved the problem, but it is still not going down, do the first one each, and remain in the same Z, it only starts to change from the 4th layer that starts to go down the Z, the second and the third it prints even Z then there is that excess plastic, the interesting thing is that the display shows the value of X,Y, Z, when the extruder moves in the map, this does not show, it is only from the 4th layer that it starts to descend, for example, it starts printing at Z=2 9 this value is the baby step. finishes the first layer and goes to the second and it doesn't change, it stays at Z=2, finishes the second layer and goes to the third and Z=2 continues. When the 4th layer begins, Z = 2.4 because I established a layer height of 0.4 mm in Simplify 3D. in fact it should be at Z=3.6. the extruder starts hitting the print.

@oliof said in Problems from the second layer to the 7th layer:
@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.
I would like to know if there is a possible solution to this problem that the system has that disregards the first layers?, the printer is industrial, and I have already spent too much time making it work with this Duet 3D 6HC card. I really need a solution, otherwise I have to change my motherboard to another brand that is less problematic and can print without so much hassle.
-
@carlinicompetizione If we knew the answer to this issue, we would have told you already! We have to find out the information to try and solve it from you, so any information you can give us helps.
it starts printing at Z=2 9 this value is the baby step
I think you're saying that you are using 2mm of baby stepping. I'd guess this is the issue, and it's probably because you have not set the Z probe Z offset correctly. Baby stepping usually only needs to be a small adjustment, maybe +/- half a layer height. Much more than that, yes, odd things are likely to happen.
Please set the Z probe Z offset again. Currently the X and Y offsets are set to 0 as well, so set them to. You're using a BLTouch I think, so there should definitely be an X, Y and Z offset. Your current probe offset is:
G31 P500 Y0; definir valor de disparo da sonda Z, deslocamento e altura de disparo G31 P500 X0 Z0.85 ; definir valor de disparo da sonda Z, deslocamento e altura de disparoYou can put this on one like together, like this:
G31 P500 X0 Y0 Z0.85 ; definir valor de disparo da sonda Z, deslocamento e altura de disparoFor setting Z probe X, Y and Z offset, see https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_testing

I believe we have discovered the problem. I started to slow down
changing microsteps from 16 to 8 and Z began to move as programmed in the slicer. Without being satisfied with the result, I went back to 16 microsteps and lowered the instantaneous on Z by approximately 30%. Then I managed to print a piece with a higher quality than what I had until then. Even so, the first to second layer is not respecting the programmed distance.
EX: the first layer starts at Z=0.40mm (this height is correct according to the baby step, also from 0.40mm or less. In the slicer, a layer height of 0.3mm was determined, so the second layer would start with Z=0.7mm , but it was only for 0.51mm, so I did a manual intervention just to understand if the next layers would maintain this flaw (I paused the printing and lowered the table manually to complete the 0.19 mm) when the second layer was finished and the third started. the value was already correct Z=0.81 mm. It seems to me like a bug in the firmware, it doesn't make sense to do that. -
@carlinicompetizione Did you try any of the things I suggested?
- calibrate your Z probe offset - https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_testing
- try a print without baby stepping - set
G92 Z0with the nozzle just touching the bed before printing, don't home Z at the beginning of the print - try a print without mesh bed compensation
And one more thing to try: yes, your Z jerk looks high to me, and so does your acceleration and maximum speed for Z, especially for the steps per mm on Z. I don't know the layout of your machine, how heavy the bed is, or even if the bed moves in Z, or if your gantry moves in Z. So the values you have might be okay, but might not be. Maybe post a picture of your printer so we can get a better idea of the size. For example, I have a bed slinger with 200x200mm bed and 2mm lead M8 leadscrews, and can only move them this fast before skipping (though they are quite small NEMA 17 motors):
M92 Z800 ; set steps per mm M566 Z12 ; set maximum instantaneous speed changes (mm/min) M203 Z600 ; set maximum speeds (mm/min) M201 Z20 ; set accelerations (mm/s^2)Yours were set as:
M92 Z1650.50 M566 Z300.00 M203 Z1000.00 M201 Z250.00Though I'm not sure why your settings would not work to start with, and then work okay at later layers. If you can share a full Gcode file, that may help.
I'd suggest setting low values for jerk, acceleration and maximum speed (ie like mine), and check if movement is correct. If it is, you can then increase them until you find the limit.

I am wondering if commas and decimals are interchangeable in config.g.
Your M566 uses commas and the rest use decimals.
@carlinicompetizione said in Problems from the second layer to the 7th layer:

In the config.g in the file everything is with a dot, but I'll check, you'll see that something typing is getting in the way too -

In these days I made several impressions to fine-tune the resolution that until then I could not make due to so much instability of operation. The last impressions with a 0.8 beak are getting good. using simplify3D that seems somewhat limited compared to Cura.
Even so, when starting the second layer, the table does not go down to the correct value. When it goes to third, it works normally. It's very strange. It doesn't make any sense. I lowered the Jerk values a lot from 500mm/min to 300mm/min. The z was at 110 I went to 60mm/min, but I will lower it more to see if it solves the problem of the second layer, it is interesting because it goes down only half the value stipulated by the slicer. But only in this layer that does this. Then take off cute. -
Sounds like mechanical binding on the z axis. Are you able to turn the z axis by hand and feel for change in resistance?
