It was print with speed 25 for perimeter and loops.
It is very slowly.
I will try print with speed 5, but I think that will nothing change.

If you set the Min Segment Length [mm] field in the Printer/Hardware tab of the Settings window to some value, then KISS will not produce segments shorter than those.

Tool tip suggests a value of (x/y resolution * 2) as a starting value, but I think segments less than 0.1mm are not particularly relevant, but even that may be too small. What firmware are you running (sorry if you mentioned it before...)?

Sorry, I really don't have much of a clue here, so just guessing really :-(

At first time my printer "TEVO Tarantula" worked wrong:
- driver X move inverted and sensor X not worked.
... and something else, I can't remember now.

I saved original firmware to binary file.
Then I downloaded source files of firmware "Repetier 0.92.8", change the file Configuration.h a little and uploade to printer.
Zip-file attached.
Then, my printer became to work correctly.
I can restory original firmware but I not sure, is this a good idea.

What the name of options for "min segment lenghth" in Configuration.h?
What I will change Configuration.h or will set option "min segment lenghth" in KISSlicer?
What do u recommend for my situation?

I found this options in Configuration.h:

Code: Select all

#define DELTA_SEGMENTS_PER_SECOND_PRINT 180 // Move accurate setting for print moves
#define DELTA_SEGMENTS_PER_SECOND_MOVE 70 // Less accurate setting for other moves 
...
#define DELTASEGMENTS_PER_PRINTLINE 24
PS: I am sorry for my bad english. :)
And thank u for reply!

Yeah, sorry, I think this is beyond my abilities.

I did find a section:

Code: Select all

// Now ignore enough segments to gain enough time for path planning
Which makes me think that segments will be ignored if the firmware can't handle the speed at which they are being delivered.

Try slicing again with KISS set to a 0.1mm min segment length.

I maked 3 gcode-files in KISSlicer and visualise Perimeters.
Length of segmets in radial path: 0.62 - 0.75 mm.
Look to difference at picture below please (short perpendicular lines is markers end/begin of segments).
