Printing problem with filament or set up?

Testpro

@phaedrux
I put those in when we first set up the new hot ends. I have only adjusted E0 because that is the only one we are using at present.

on the other question yes it will move up manually while printing using baby steps on touch screen 0.02 or on Net 0.5.

when i home it will lower the bed and when x & Y are done, the bed raises and stops like it should.

Could this have something in my slicer settings doing this?

@testpro
Yes i defiantly have something wrong with the set up of the Duet board in software or in the slicer Prusa.

i went over the slicer setting and basically have the bare minimum setting i think, 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 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. wired.

I would suggest that you change your tool offsets for tool0 to be x0 y0 z0, and then you can work out the offsets to tool1 from that 0,0,0 point.

I don't understand what you mean here.

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

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

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.

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.

To have prints centered on the bed you specify the bed origin in Prusa's Printer setup.

Prusa Bed.jpg

Clicking the Set button next to Bed Shape brings up the dialog shown where you specify the size of the bed and the location of the origin (the X = 0 Y=0 point).

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

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?

Testpro

@fcwilt
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.

Phaedrux

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.

Frederick

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.

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.

@testpro said in Printing problem with filament or set up?:

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.
