It can indeed be resolved with the new threshold settings I mentioned in the support article.
This is what I changed:
Here is the project file Mari_CFFFP_Project Save.3mfThe settings changed are a bit extreme. It will differ per printer if it can indeed be printed.
If your printer is still struggling you can also just increase the horizontal expansion until you see very little white spots indicating start stops.
WOW! Thank you so much! That made an incredibly huge difference! The only thing now (which isn't the biggest deal) I see is that the font is just a little on the thicker side, almost as if it was BOLD. So they are a little too close due it being like that. Is there anyway to keep the quality like this, while not fattening up the font as much? Here is a before and after of another font I printed after using your suggested settings...I added a small amount of 'ironing' at the top as well.

Hey @xoxoang,
What a cool project 💝
Which version of Cura are you using?
In Cura 5.x we introduced Variable Linewidth Engine that should be able to print your files well enough with the correct settings. You can read more about them here:https://support.ultimaker.com/hc/en-us/articles/4792077687068
I see a lot of white dots indicating starts and ends of lines, That often also indicates retractions and not all printers handle that well. With the amount of oozing I wonder if you have the correct temperature for your material.Do you have a project file for us? It contains the printer and settings we need for troubleshooting.
To save a project file go to File -> Save project.Hi. Sorry I am re-commenting as I forgot to do it as a 'reply' to make sure you see it. Thank you for responding! I messed with the temp a little bit and it did correct the oozing a bit, however everything else is pretty much the same issue. Here are my current settings (after the temp correction). Thank you again!
Oh and I am using Cura 5.2.2
Thanks!

I am trying to make stamps for soaps/clay/cookies/fondant and it's coming out horrible. I don't know what I am doing wrong and I have spent countless hours, actually... days, just trying to figure out how to fix it myself and messing with the settings in Cura with no resolution. What am I doing wrong? Please see pics for examples.
I have an Alta + and originally wanted to use their 3D software, and while the print is pretty "smooth" and nice, it just slices any text/font horribly and leaves lots of holes and gaps in the text no matter what. Apparently the program itself is just horrible (said by everyone who has ever used it) so I opted to learn the Cura program instead.
While the slicing in Cura is MUCH better and the text/font doesn't have any gaps/holes in the letters, it does however have some openings in between the lines, and the layers are not smooth at all and just look horrible (see pics). I honestly just don't know what to do and I am beyond frustrated. They seem to stamp fine, but the appearance is ugly and won't be useful for food items if anything were to get caught in those line gaps either.
The text/font is NOT too small for my nozzle size (0.4) because it prints just fine using the Silhouette 3D Software and doesn't come out with the "line" look, nor does it look gunky either. It actually looks great minus the issues with slicing. I just cant use that program due to the slicing issues and there is just no way around it as that program is extremely limited when it comes to adjustments in the settings, and it also prints sooooooooooo slow. I just really want to get the right settings in Cura. Please help!
Any help is much appreciated!

You don't have a heated bed?
What is your "retraction distance"?
What nozzle size are you using?
This line moves the Z down so the nozzle is only .02 above the bed
G1 Z0.020 F540 ;slowly lower
and two lines later it squirts 50mm of filament into that tiny gap
G1 E50.00000 F100 ; extrude 50mm filament at 100mm/m
This line is missing a carriage return:
G1 Z0.800 F540G1 E5.99500 F3600.000 ;lower to buildplate begin extruding begin smear/smudge
I think it should be:
G1 Z0.800 F540 ;lower to build plate begin extruding begin smear/smudge
G1 E5.99500 F3600.000 ;un-retract - but there is no previous retraction so this is more blobbing
I would certainly make some changes but I need those questions answered before I start to scribble gcode.
Hi. No the Silhouette Alta + doesn't have a heated bed. The nozzle is 0.4mm. I am not sure about the retraction distance or what that means, sorry,. I do know that the printing area is 124mm diameter (round bed), and 130mm tall.
I was able to fix the issue (temporary fix) by adding some blue painters tape on the bed to make it a hair higher. So now the nozzle touches it enough that the print now sticks. This was the only solution I could come up with for now. So the bed basically needs 2 layers of tape. 1 layer of tape is a hair too low.

The problem is likely to be within the printer (Z-offset if you have ABL, Z binding, under-extrusion, etc.).
As this is the "UltiMaker" forum - you would get better support from the manufacturer of your printer, or maybe there is a sub-group somewhere like Reddit where you can get support.
I'm confident that the Cura gcode file will show that LAYER:0 starts at your "Initial Layer Height".
If you open a gcode file in a text editor you should see this around the "LAYER:0" line:
;LAYER:0
G0 F9000 Xxx.xxx Yyy.yyy Z0.2 >>>this is the "Initial Layer Height" you enter in Cura.
;TYPE:SKIRTThank you. I am still very new to all this and I am having trouble finding the area I would need to adjust. Can i show you what I have in my current setting now for the start gcode?

I have input the recommended gcodes and using my Alta Plus with Cura looks promising so far. It performs the initial blob and all correctly. But then when it moves up and goes to start the print job, the nozzle is just a hair too high off the bed so the first layer doesn't quite touch the bed. How do I fix this? Thank you!

Hello Everyone.
I just signed up but I am not new here by any stretch of the imagination.
I finally feel like I have something worth while to contribute to this ongoing discussion concerning the silhouette Alta / Alta +
I have both an Alta and an Alta +_
I have spent hours well weeks even working out everything there is to know about this machine. (that Silhouette wont tell you and neither will the actual maker of this machine..)
First. this is a repackaged Colido d1315 from Print-Rite.
They are the only retail outlet on the web (that I am aware of) Beside silhouette who is always sold out. (by the way the filament is Colido filament as well )where you can get parts for the Silhouette Alta /Alta + Such as a new print head, circuit board. etc.
Also the silhouette alta + was released amazingly at the same exact time as the D1315 +
I have rewritten the Calibration Code for the Alta So that you do not have to use the Silhouette 3D Software.
And the borrowed the Colido code for filament change so that you can use any slicer that lets you send gcode or uses scripts
(I may write a couple of Cura Scripts but I haven't decided yet)
I have also re-written the Start Code for the Alta So that you don't Fall Asleep just waiting for it to finish the prime tower and the the smudge/smear prior to print. Also for anyone else who has experience that cracking/grinding/ popping sound just after the prime tower I have gotten rid of that.\
and for anyone curious as to whether or not i am pushing the alta outside of its design specs.
Here is MY hard coded print-rite written and embedded settings
echo:Stored settings retrieved
echo:Steps per unit:
echo: M92 X100.00 Y100.00 Z100.00 E97.90

A couple of hints:
UNLESS YOU KNOW ATMEGA2560 /ARDUINO/ FTDI in system programming DO NOT Flash you Marlin Firmware. At least until I or someone else figures out a work around I REALLY want auto bed leveling.... Print Rite took marlin OPENSOURCE changed/complicated the flashing procedure removed some commands and didn't add a bootloader to their system and called it their "in house developed specialized os. its just dumbed down marlin 1.0
if using their filament
THESE FIRST TWO THEY NEVER TELL YOU ANYWHERE BUT IF YOU WERE TO FRESH LOAD THEIR 3D SOFTWARE YOU MIGHT NOTICE
210 C temp
115% extrusion Rate
it has a .4mm nozzle but you should be laying down .45mm to .6mm lines and .35 for things like supports
and I usually run .08 to .16mm layer height
Speed regular prints 45-60
Detail prints 35-45
Travel 70-80
jerk 20
acceleration 3000 to 8000mm sq/s
maximum dimensional extrusion 12
YES because of the enclosed frame YOU CAN USE A BIG OLE 120mm PC Cooling fan straight off of the main board Labeled fan connection and the software will control it. Cura included (honestly it works better than the alta + built on rinky dink filament fan which blows but not in the way it should,
And it is configured to use an sd card in fact the firmware still searches for it at load (i think that's how they flash firmware)
That's for starters
I am attaching
all the g-code files I referenced
Index of uploaded Files.
Start an End G-Code -- Revised for speed and accuracy put these in your cura settings
Complete Calibration routine -- each tower individually, or all towers plus center
load/unload filament Captured from the Colido Software matches silhouettes exactly.
Complete Capture of Silhouette Alta Reset routine
if this is received well and people are interested, i Have Cura Print profiles , Slic3r config, Repetier Host config and a few others as well for the Silhouette Alta/Alta+
Later all

Thank you for this! Here I am reviving this in 2023. The Silhouette 3D program is horrendous. I just downloaded Cura and found this thread. Cura is on v 5 now so I am hoping this will work! I also have the newer Alta +

Printing Text/Font issues in Cura. Please help!
in UltiMaker Cura
Posted
Hi. So I did everything you said in #1-5, and set the horizontal expansion back to 0, just to test out if I could print the letters thinner with the same quality. Everything looks pretty good and smooth, except there are a lot of white squares again for start/stops in the same exact spots. I tried messing with the seam options and randomizing it but it didn't make a difference.I think it is what is causing the little spots around the letters in certain places. Here are pictures.
Also, I believe my temp issue is resolved, but as far as the retraction settings, what do you suggest?
Thank again you have been such a great help thus far!
