I cannot make this work :-(

Hi All,
I got used Voron 2.4 with Duet 2 wifi board. I also have Creality CR6-SE with Klipper. I enjoyed the CR6 for some time, but i want something bigger and faster and also possible to upgrade. The Voron machine i got was a mess (it was cheap) when i got it. So i rewire it, cleaned it and get some new parts for it.I never use Duet boards and REPRAP but i was able wipe the firmware and upgrade it to the lastest version of REPRAP 3.4.0beta4. I calibrate the PIDs, calibrate the bed, calibrate the Z offset and e-steps. But when i start printing it seams like the extruder is extruding slow, the plastic have weird gaps in the skirt and it doesnt really stick well to PEI bed. I changed couple times the Z offset, because i thought that is too low or too high, but nothing works. On CR6 I always printed on the glass bed and it was fine. This coarse surface little bit confuses me.
Could you please check my config files if i am doing something stupid?

@dank0 All I would say is klipper uses RMA for motor currents and RRF uses peak, so your motor currents might be a little low.
Multiply the klipper values by 1.4 and that should get you more in ball park or check the datasheets for the motors you are using and set the values at ~80-85% of the maximum current. -
@dank0 this looks all very strange to me:
M557 X25:300 Y25:300 P5 S280
starts at 25 and that's it, because +280 is bigger than 300bed.g G30 are 4 points, repeated 3 times each.
Both don't fit the image of the mesh. Maybe doubled config file, or taking an old heightmap.csv or something else?
-
@joergs5 the 4 points is the position of the screws and it only works when i do true bed leveling. the M557 is the area and number of points for mesh compensation in my understanding. And when i do the bed leveling it does exactly what is in those configs. go over the 4 points and after do the mesh compensation with 25 points. I don't know if this is correct, but it did all those steps exactly how they are defined in the config and the height mesh didn't look incorrect to me so i was thinking that this is the way to do it
-
@dank0 ok, I am not a mesh specialist, I overlooked P5, but S280 is IMHO then superfluous.
The rest of the config looks correct for me, I would only check
M404 N1.75 D0.6 ; Set nominal filament diameter to 1.75 and nozzle width to 0.4
whether the D parameter is correct. -
the S parameter in the M557 line is the probe spacing so s280 will only probe every 280 mm on the bed try setting it to S20!

It might help to give the PEI sheet a light scuff with steel wool or sand paper.
-
@dougal1957 this is what I also thought, but the P5 means 5 points in xy direction, and S seams to be ignored then.
-

:@dougal1957 this is what I also thought, but the P5 means 5 points in xy direction, and S seams to be ignored then.
I had missed that cos P5 is also used as a probe type but even so 5x5 grid on a 300mm sq bed is a bit wide I would suggest.
Also would the S280 coming after the P5 over rule that (not sure but It is a possibility)
-
@dougal1957 I second this. Maybe the bed is bent by temperature effect and more points will give better mesh compensation results. The mesh measuring should be made with the printing bed temperature. @dank0 , is the bed heated while printing?

how did you calibrate your e-steps? extruding through the extruder when at temperature?
that bed mesh is not the worst i have seen in a long way. I am and assuming you have the right probe offsets set so its applied correctly.
Try printing without mesh compensation enabled in the center of your bed. use a reasonably large layer height (0.3) and you may need to baby step to get the first layer down good enough. I would print a simple test part to start with, and confirm that the rest of the print is ok (the first layer might not be perfect at this point).
-
@joergs5 nope i didn't heat it up the bed before measurement . I will do it. Thanks
-
@dougal1957 I will add more points and test it, thank you
-
@t3p3tony I heat it up to 195C, measure 11cm, extruded 10cm with G1 E100 F60 and measure the rest and calculate. It extrudes perfect amount and keep 1CM. I think the e-steps are ok. I will try disable the bed compensation and let you know. thanks

Hi, I might be barking up the wrong tree here but I have a few questions:
AFAIK, the bed.g is used for bed leveling G32 (quad gantry leveling) which a lot simpler than that.
For bed mesh calibration G29 the mesh.g is used and that is also a lot simpler IMHO.Also The comment says 0.4 nozzle (I don't use that gcode) but you have 0.6
EDIT: I might have read your config a bit sloppy but when do you do the run G32 QGL?
-
gixxerfast what do you mean by this? "but when do you do the run G32 QGL" . you are asking when i am calibrating the bed?
also to be honest i believe that my configs are not correct/sloppy, that is why i am asking you guys who knows duet boards well. I am learning.
I got tired of the coarse surface and i turned the PEI surface to the other side, and it prints ok( still not great quality), i need to figure out the pressure advance settings. But i will be definitely buying new bed.
Also one thing is still question for me. I tried Cura and Simplify3D for slicing with Reprap gcode flavour and it prints slow, how do you guys setting the speed of your prints?

:bed.g G30 are 4 points, repeated 3 times each.
Since you seem to be using firmware 3.3 you can make use of it's features to avoid duplicating those sets of 4 points and always running 3 leveling passes even if they are not needed.
Now the points in the G30s below are for my printer by the approach works for any printer just by changing the points.
What it does is run a pass (4 points in this example) and check the results. If the results are not within the specified range (0.02 in this example) it runs another pass. It will run up to 5 passes trying to get the result within the specified range. On my printer it most always finishes in 2 passes.
Just FYI.

@fcwilt Thanks for the bed.g example - it works nicely

Glad to hear that is worked.

@dank0 Sorry, I don't mean that your config is sloppy. I mean that I read them not thorugh enough.
No, what I am asking is when are you doing bed leveling -> G32 which uses the bed.g macro and when do you do a bed mesh G29 that uses the mesh.g macro. To me, I could be wrong here, it seems like those are mixed in your config.
On the Voron 2.4 the routine is always (very roughly) G28, G32, G28 (G28 Z)and sometimes a G29 depending on how large the print is. That converts into macros as homeall.g, bed.g homeall.g (maybe homez.g) and then maybe a mesh.g.
Anyone who knows anything different may please correct me
