Printing problem with filament or set up?

ok yes a little more detail on my part would help.

the slicer is set to 15 x, 100y for the center of the bed and the machine homes close to it 170 x, 85 y.

I don't understand what you mean here.

1A) in the Prusa slicer i have set the origin of E0 to X= 150 Y= 100, this will put the Print dead center of the of build plate. but when it prints there is only a fraction of the Print Cube on the front left corner of the print bed.

i set this cube up for printing dead center of the board but when it runs it the back right corner around y= -80 & x= -100 to -150. which it the front left corner of the board.

I don't understand what you mean with this either.

2A) This is stating when i print the print is in the front left of the print bed in reality but in Prusa slicer it is dead center of the build plate.

Ok, but why? I don't understand why you're telling the slicer that.

; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minima
M208 X280 Y180 Z300 S0 ; set axis maxima

Your bed has the 0,0 point in a corner, not the center.

Can you show a screenshot of your settings from the slicer?

yes it does and that is done my end. except my Y = 200. and the print never comes out in the center of the bed at all. if i have this way as you have it shown it will print front left hand side and if i move the item to the far back right and then slice it still comes up front to the right but not as far. but if i move the item to far back right in slicer it is off the bed in slicer and will not slice.

so at this time i have the origin set to x=0 y=0 just so i can get it on the board. still not right at this point.

Please post a screenshot of the settings.

Based on your config.g M208 settings, the origin should be x0 y0 and placing an object at the center of the plate in the slicer should cause it to print at the center of the bed.

Your M208 settings are possibly incorrect or need some adjustment. Can you tell me if the endstops are off the edge of the print area? As in, does the nozzle have to leave the printable area to strike the endstop? If so, we can adjust the M208 values such that the 0,0 point is still on the printable area. For example, if the nozzle must move -20mm past the edge of the bed to hit the endstop, then the M208 minima would be -20.

You mentioned something about setting the Extruder offsets to X150 and Y100.

That is very likely wrong.

ok at this point i have cleaned out all the slicer files from the last month of trying to get this to work.

I also took out the slicer completely from my machine and reinstalled a new fresh copy of the Prusa slicer 2.3.3.

i did mover the origin back to the front front left corner in the slicer as well. so this is where it homes for now. i would like it to home in the center but this is not practical at this time.

now i have ran through the slicer again with the factory settings and put the basic information in and now the Z works pushing the nozzle closer or away with the touch screen baby steps. Plus the printer now increments for the layers where before it did not.

what part of the slicer settings you need to see?

Not practical - what does that mean?

Homing does not have to mean moving to X=0 Y=0. Homing is simply the process by which the firmware determines where things are on the X,Y,Z axes.

One of my printers homes to Xmax and Ymax, one homes to Xmin and Ymax but they all have the origin (X=0 Y=0) at the center of the bed.

Having the origin be the center isn't too hard. See here:

https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin

One way or another, the firmware and the slicer just need to agree on where the 0,0 point is and what the size of the bed is.

Ideally everything. If you load a small STL and then do a file save project as .3mf and upload it here we can see all of your settings.

100mm_Rounded_Cube.gcode

ok first test print incremented as it should while printing the first layer and fine tuning it.

once i confirmed the Z was incrementing for the steps of adjustments and for the second layer. i did another test print but this time i added in the bed compensation and now it will not let the Z axis increment and will not increment on second layer either.

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.

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?

fcwilt

@testpro

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.

100mm_Rounded_Cube.gcode BB.gcode

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

Phaedrux

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
