I am designing an expansion Kit that could allow some new functionality and improved print quality on Ultimaker S3 (later S5). I need to replace the second feeder motor by a smaller stepper motor rated at 0.2 A. Any advice on how to reduce the current for the smaller motor? I will be adjusting the G-code later to use the second feed motor for a different function while the first feeder motor operates normally and prints using core 1 normally.

Hello Users of Ultimaker 3 Printers. I am having surface defects on my prints with Ultimaker 3. I believe the problem could be belt tension, so i followed the instructions to adjust tension. The surface problem persists and the corners appear to strongly overshoot while printing at 30mm/s. Any suggestions for a solution? Anyone familiar with the problem, why does it happen and how to solve it? I attached pictures.

The extra travel and deposition does not appear in the slicer.

I am trying to print a simple part as shown in the picture, the nozzle however keeps traveling to the corner and deposits an extra unconnected lines on the left. Anyone has had this problem ? I could not find the reason for this in the cura slicer settings.

Thank you for the comment gr5 that helped a lot. 1) The test is also done in the build direction , the layers are pulled apart. I will try to program the nozzle to keep going without extrusion an extra distance forward in gcode. 2)Fans are on 100% 3) 4) I will print slower and maybe make pauses between layers or print two parts at the same time . 5) i will run it at 10mm and maybe try with thermal camera to see differences . 6)That is a great tip , i will disable that , slice again and check changes in the gcode. Thank you for the very helpful tips.

Thank you for the reply smithy. I uploaded the 3mf and a picture of the slice. I am printing parallel non connected infill lines to test bond strength . (This geometry is perfectly suitable for my test setup) UMS5_Block-print.3mf

I tried to print a plate upward with 0.8 Nozzle. It seems to have over extrusion and beginning and at end , but the middle of the line looks perfect . This was done on Ultimaker 5 PLA material. Any suggestions on how to fix it ?

Thank you for the replies. I will try this to get every layer in different color. So i am calculating the length.

Has anyone tested extruding pieces of filament of different color ? Any suggestion for a better way to do this ?

I just found the easy solution staring me in the face in cura !!! Just switch Infill extruder to "Not overridden".

I managed to slice each part independently and generate two gcodes. Then i combined the gcodes in notepad++ and it is now working. I hope the manual solution could become a feature in cura at some point.

I am trying to print a part with two materials. I need to fill one section with nozzle 1 and infill with nozzle 1 and then when i switch to nozzle 2 , and i want the infill to also be nozzle 2 . Cura 4.2.1 says " The settings is always shared between all extruders " it always sets the infill to one default nozzle. I cannot independently select the infill nozzle. Is there already a method to remove this link between nozzle settings ? Is there a work around ?
