Are you following the instructions here for setting the G31 Z trigger offset?
A BLtouch is a good option if your bed surface doesn't work well with an IR probe, which perhaps yours does not. Though it does have it's own set of demands to work well. Because it's a retractable probe, it requires a bit more wiring and configuration.
-
the link you have is what i have been following this whole time calibrate the Z probe. i can not get a consistent result when repeating the read out. two or three times it reads one thing and then it just goes and comes back with something totally different. From project to project and from day to day i have go back over things and reset them because it will not do what is supposed to.
if anyone have a better idea i am all ears because right now it is not consistent. i am getting tired chasing the same issue around.
so what other options are there?
-
The main variable for the IR probe is the IR reflection of the bed surface. So if you've tried with a plain piece of paper on top of the glass and it's still highly inconsistent than it's possible the probe itself is damaged/failing/dirty.
Can you post a photo of your probe and print head?
-
@phaedrux
yes i have done the paper on the top taped down and get the same result of a very lumpy height map. the sensor has been cleaned as well. Several times.i am thinking this is so frustrating because it reads rights a few times then goes and does something else for readings. the reading are consistent only for 3 to 4 times thin it changes .
i would like not to put more money into this project but if the Z is not consistent, i do not have a choice.
the one with the blue cover is E0, E1 is not being used at this time and nozzle is removed.

You'd have to take the probe out to get a good look at it, but it seems well protected there.
If you don't want to get another probe you could try manual probing instead. It's a bit time consuming, because it's a totally manual process, but it would let you get good accuracy to confirm that things are otherwise working during a print.
to set manual probing.
M558 P0 H4 F200 T6000
G31 X0 Y0 Z0 P500
M557 set whatever your current grid range is, but change to P3 to create a 3 by 3 grid just to reduce the number of points you have to probe.Now when you do a G28 or G29 when it gets to requiring a G30 to probe the bed you will be prompted to jog the nozzle down manually.
-
@testpro
ok so i put the above code in one line at a time and the M557 will set the grid.
so when the extruder moves to a location it will let me know to lower the nozzle until it cripsa sheet of paper and then it ok or whatever it will state and it will move to next point and do it again?if this what you are saying.
-
Yes that's the gist of it.
Test it first with a single G30. It should pop up a dialogue box to let you jog Z.
-
ok done a manual bed leveling. but now how do i turn this off.
the thing will not home on z i have to adjust it.
-
I'm not sure what you mean. The idea is that manual probing replaces the probe calls when you don't trust the probe. To turn it off you would change the configuration back to your other probe I suppose, but then if you use that to home and it doesn't give a good result your Z0 would be off and you're back to square one.
-
@phaedrux
ok i have done the manual bed leveling. then i cycled power on the unit and everything seems to be good.so then i redo the Z = 0 over again because i know it is off. My height map is way above the grid.
so i run down the codes and manually adjust the nozzle to the bed and then tell to lower 5 mm. then i put in G30 S-1 and bed moves down away from the nozzle but never goes up and the console states "The Z probe never triggered". so something is wrong somewhere.anyideas? ```

@testpro said in Printing problem with filament or set up?:
then i put in G30 S-1 and bed moves down away from the nozzle but never goes up and the console states "The Z probe never triggered". so something is wrong somewhere.
Is your Z axis going the correct direction?
-Z moves the nozzle and bed closer together?
+Z moves them farther apart?@testpro said in Printing problem with filament or set up?:
so then i redo the Z = 0 over again because i know it is off. My height map is way above the grid.
Using the IR probe, or the manual probing?
-
i just turned the machine on and homed all and it done just fine.
then i went to move screen and and hit +5 and the bed moved down.
on the height map i got a really low map using IR probe and a really high map using manual. so i am going to say it does not matter witch i use. or the Z axis operating backwards has something to do with it.?
-
When you created the map, had you done a single G30 at the center of the bed first? Normally that would be part of your homeall/homez.
What do you have in your homing files now?

The manual probing height map should be accurate because you're the one that is setting the actual position. Which is why I asked if you if there was a G30 first to set the Z0 position. Seeing your files, as long as you ran a G28 first to homeall, it should have had an accurate Z0 position and the resulting heightmap should be ok. Do you have a photo of it?
@testpro said in Printing problem with filament or set up?:
G1 X10 Y10 F6000 ; go to first bed probe point and home Z
G30 ; home Z by probing the bedIdeally you would want to use the center of your bed for probing.

@phaedrux
ok i had to reprint the bottom hot end piece due to the fact the one my boss printed actual broke because it was printed wrong.so i printed a new one with my resin 3d printer and it worked good and now have it installed. the height map is much more even now and the first layer prints great now. the more robust lower hot end helps alot.
now it seems the Z axis will not increment as it prints for some reason. the Z axis stays at 3.96 the whole time printing. i have not idea what i have done but that is what i got. any ideas on this one?

Does the z axis move up past that point when you jog it manually?
-
I notice your tools have a z offset. Where did those come from?
-
@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?
