Multicolor sequential printing
Hi,
I try to create multicolor text for a front panel using Sequential printing in Prusaslicer.
- The characters created in Fusion 360 are 2 layers high (0,4mm height).
- They are grouped by color and exported as 3mf files
PrusaSlicer 2.7.1 (target=MK4 and no MMU) for sequential printing)
- The extruder clearance for the sequential printing are: Radius:0 and Height:0,7mm
- the lift height is 0,7mm in Printer settings/Extruder1
In Prusa slicer, characters with the same color are parts of the same object (to avoid multiple filament change with the same color).
It works fine if the characters in the same object are next to each others, but if an other object (character) is inserted between them, the slicer refuse to work " Error: Some objects are too close. Your extruder will collide with them." Of course it's not true, there is no overlap between objects and I guess it's a bug in Prusaslicer.
for example: Prusa => Pr=red u=yellow sa=blue will work, but P u=red r =yellow sa=blue will fail.
How to fix this ? ... in a next release ?
For now, I have to use a more basic tedious solution without Sequential printing. I must create a g-code file by color
RE: Multicolor sequential printing
I got the same problem. My plan was:
-turn on seq printing set area to 0 to turn off safety distance
- add z movement to 1mm
-then First print Letters/Logo
-then print Body
Is it possibly to turn off this savety area?
RE: Multicolor sequential printing
Don't use sequential printing for this, use the process for "Manual MMU" with virtual extruders. The attached image shows an example for this using two colors, but you could use more if you like. Search for "Manual MMU" in the forum. It has been explained several times.
RE: Multicolor sequential printing
Hi, I tried this solution in the past
To get good colors, I always print a minimum of 2 layers for each characters. One layer is not enough. I tried to use virtual extruders but it doesn't fit my needs.
With virtual extruders , if you have 5 characters, 5 colors and want 2 layers for each of them, you have to change manually 10 times your filament (it's a waste of time). with sequential printing you should change filament only 5 times.
Unfortunately the sequential printing bug limit this usage. You can't print the same color on 2 different charcters if another color character is in between.
I don't understand why this bug about "false positive collision detection" is not fixed .

Thanks a lot for your hint. I will check this 😎
