[not yet solved] Tevo Little Monster DuetWifi errors

@giostark What do you have in your slicer end code?
-
@phaedrux
just this :
M104 S0 ; turn off temperature
G28 ; home -
If 60% is still too low for an idle hold current try leaving it at 100% so the motors stay powered.
-
@phaedrux
I noticed Matter Control (usb connected) send in the terminal when I stop the printer via "cancel" in MC panel those gcode : N5 M84*26.
Instead If I press the stop or emergency stop in WC (so no usb cable) , I see the popup of M112 and M999 and the head fly down.
I tried to print via file.gcode and there is no M84 inside.
And the only one way to stop the printer via WC is the stop emergency button. (there is not a cancel button)
When The printer is finished, after some second, the head crash in the bed. Of course is just matter of time before Ill break the glass. In the last print the head melted the plastic falling directly on the printed part
-
Does it crash down on to the bed immediately the print finishes, or 30 seconds later? If it's immediate then there must be a M18 or M84 or similar command at the end of the GCode file.
-
Was after 30s , so I found in the section drivers in config.g this "M84 S30 ; Set idle timeout" and I now excluded it. I have settled at 60% the motor, lets see if if enough
-
@giostark If you removed M84 S30, it will never drop to 60% idle current.
-
Have sense...ok ,
now I launched a print . It will take near 6h lets see what happen. -
Some progress...
1- I discovered that the problem of crash in the bed depend by MatterControl. It look like after the finished printing it send some Gcode independently by the printing data.
If I generate the file.gcode , now that I have commented the M84 , the head stay in home position like expected . So i have to discover where to put attention in MatterControl for resolve this.
EDIT-2 ! And here how to solve this ! https://github.com/MarlinFirmware/Marlin/issues/1485It suggest where to look: C:\Program Files (x86)\MatterControl\StaticData\SliceSettings\Properties.json
Look for this line:
"DefaultValue": "M104 S0 ; turn off temperature\nG28 X0 ; home X axis\nM84 ; disable motors"
And remove the M84 ! Or just put in front the ";".
For configure the delta printer LM there is not a pre-built profile so you must choose "other" so You have also to change the "Other.printer" profile in the folder C:\Program Files (x86)\MatterControl\StaticData\Profiles. Looking always for the M84 and remove or comment it.
The printer configurated come located here: C:\Users{user}\AppData\Local\MatterControl\Profiles\guest . So if you have already reconfigured the printer here you can change the M84 value.
in linux is here : ~/.local/share/MatterControl
Fine.2- Some printing issue:
I discovered that for small printing object base the glass is perfect , BUT for big object base I cant let the corners stay on the glass , ending to ruin the print.
So for big printing I used one thermal adhesive pad and hell the print stay down and the problem is to remove the printed part from it. Any way I'll see what to do.
Now suggestion about those print?
This is the 1st layer, and what you see is what is against the bed.
Here ,the lines are not lines !!! This is incredible...look ! seems like a patchwork !
I used the infill 100% and could be this the issue? In the preview of MatterControll those that are broken and discontinuous lines instead appear regular lines.
The motors need to be cooled? I settled the 1700mA of current because the motors need 1.7A so should be fine right? Or should I sett less of the target specification?
Here, always the first layer, look melted. I should use some fan percentage? I read ABS didnt like cooling (but I experienced that for small print it is necessary)
The last picture show How ugly the finish looks. In some places is perfect and in other is horrible.

That looks to me like a first layer that just isn't sticking very well.
The flow rate needs to be correct, and the first layer height needs to be accurate. That should give the right amount of flow and squish. If it's too close or extruding too much, the plastic can squish out and curl up.
Then temperature needs to be high enough that the plastic stays molten long enough to bond. This is why a high bed temp is needed for the first layer.
It also helps to print the first layer very slow.
How fast are you trying to print?
What layer height are you using?
What is your extrusion width?

I settled 45mm/s and 30% for 1st layer and 100% width for 1st layer and perimeters. The fist 2 pictures where about the contact with bed , the last is the top face.
Can you tell me something about the fist picture? Especially in the center the lines are not lines. They seems interrupted and the filled again...it is really weird. -

That's exactly what I was talking about. I think you are over extruding, and the plastic is getting pushed up and then smoothed back down when it comes back the other direction. That's why the lines look woven.
Your top layer looks like it's over extruded in some areas. Especially the left side. But then it looks like you're under extruding on the right side.
Have you calibrated your E steps?
13.5mm/s sounds ok for first layer speed.
I'm not familiar with MatterControl as a slicer, so I'm not sure how it behaves.
-
Yep , I have calibrate the E step , BUT is arriving the Bondetech BMG and I'll put on it the 0.9 motor , so I should gain some better extrusion.
Maybe is worthy to wait that I have installed it before losing time looking for a configuration that must be replaced.
Thanks you for your time and attention. I'll try to investigate your points and I'll write back.

Hi folks !
I'm facing this issue: the calibration report an absurd bed leveling. (see the picture)
I installed the new motor (changing the microstep to 160 in config.g) that look more accurate but after this the mesh bed compensation become more strange.
When I try to print large object one side of the printing is just few attached the other is strongly attached.
If I send the calibration before the print and with the M122 I can verify the mesh compensation is loaded but the result is as above described.
Im using the last firmware (but this is not relevant maybe)
Re-calibrate the Z-probe have not produced improvement. -
-
Some post above there is a calibration that look like very different
-
I presume you ran auto calibration before you generated that height map. Did you run auto calibration (G32) before generating the height map (G29)? Assuming that you did, what was the reported calibration deviation; and are you using the same bed.g file that you published in your earlier post in this thread dated 21 September?
-
Hi dc42,
This is the actual bed.g :
*; bed.g
; called to perform automatic delta calibration via G32
;
M280 P3 S160 I1 ; clear all BL-touch errors
M561 ; clear any bed transform
; generated by RepRapFirmware Configuration Tool on Mon May 22 2017 22:56:20 GMT-0400 (Eastern Daylight Time)
G28 ; home all tower
G0 Z400 ; Move while giving the BLTouch time to clear the error
; Probe the bed at 6 peripheral and 0 halfway points, and perform 3-factor auto compensation
; Before running this, you should have set up your Z-probe trigger height to suit your build, in the G31 command in config.g.

; Use S-1 for measurements only, without calculations. Use S4 for endstop heights and Z-height only. Use S6 for full 6 factors

;G1 X0 Y0 Z150 F15000 S2*Turning on the printer the M122 didnt load the mesh , so I do all the time the calibration and after this the M122 report "mesh" for the bed compensation.
Bed compensation in use: mesh
Bed probe heights: -3.115 -2.859 -2.963 -3.287 -2.919
Yep ,I do the auto calibration from the web interface pressing "auto delta calibration" , then the result is that image you can see this post above.
They look to me strange number...are too big... -
Boh...I mean boh...just because i didnt know the cause>effect related to what im doing...anyway...
I changed the bed.g coordinates for the calibration from actual to the one taken from the Eric files and this is the result LOL Maybe the S6 compensation or calibration point , against the S3? More point to read?

Yes, using S6 normally improves the delta calibration by calibrating inaccuracies in the tower positions too.
When you run G32 several times in succession, what deviation does it converge to?
