Printing problem with filament or set up?

What does your height map look like?

Either the file is too large or not allowed by the forum software. If it's more than 4mb, upload it to a cloud drive and share a link, if it's less than 4mb, try adding a .txt extension to the file and upload again.

now it will not let the Z axis increment and will not increment on second layer either.

Do you still have that weird 5mm z offset for the tools?

Testpro

@phaedrux

the file format is not allowed. and no more offsets for the tools at this time.

100mm_Rounded_Cube.txt

still can not figure out why z will not increment with the bed compensation working.

Testpro

@testpro
after doing the manual bed leveling several times my height map is -0.22 to 0.021.

so pretty even at this point.

Testpro

@testpro

at this point the objects are now printing in the center of the bed. so that is cleared up for now.

i have found the reason why the Z axis was bit incrementing. in the slicer Prusa 2.3.3 under print settings. Custom G code i had the following:

G28 ;home all axes
G29 S1 ;allows bed compensation
G1 Z5 F5000 ; lift nozzle

this would not let the Z axes increment while printing but i changed it to this :

G28 ;home all axes
G1 Z5 F5000 ; lift nozzle
G29 S1 ;allows bed compensation

and it now works just fine. why is this an issue? or did i just stumble on to a bug?

While printing any normal Z move is going to be affected by mesh compensation.

Enabling mesh compensation is the very last step in my "print start" code.

That doesn't make much sense to me either.

Can you share the actual gcode file now?

I had a look at the 3mf you uploaded and your settings look ok. Though I would suggest enabling relative extrusion in the slicer printer settings tab. Relative E distances I think they call it there.

ok i have gave you the gcode for the Cube which printed very well and then the make robot which is not printing so well at this time.

Sorry this is the latest and best print file i have at this time. the one above is an older version of this file.

It looks like your retraction settings could use some attention in addition to enabling relative extrusion.

Retract on layer change, yes
Retract always on travels, not just when crossing perimeters
Retraction length is 2mm, which may be too much or not enough depending on the hotend and extruder. What do you have on there by the way?

Retraction should reduce the oozing.

Retractions speeds and extruder jerk and accel should be tuned as well.

Based on your last config that was posted I would use

M566 X900 Y900 Z60 E3000:3000 P1
M203 X12000 Y12000 Z600 E6000:6000
M201 X600 Y600 Z200 E3000:3000

I would also add M204 P600 T2000 to that section of config.g to allow faster acceleration on travel moves for less oozing, but lower on print moves for quality.

That should allow the retractions and layer changes to be a bit quicker which can help with the layer seam bulges.

Your print and travel speeds are also quite slow. 20mm/s on solid infill, 15mm/s on top solid. Even your first layer is faster at 30mm/s. Travel speed only 100.

Try setting these speeds.

Retraction: 50mm/s length 1mm
travel speed: 200
inner and outer perimeter 50
solid infill: 50
infill: 50
top solid: 40

If those speeds work ok, bump the 50s to 60s
