Extrusion Calibration?
-
Thanks...
Let me repeat it: The roughness comes from over extrusion because the gab between the nozzle and the bed is to narrow.
I will re level the bed and will print tiny batches of first layers. Lets see how they look than.

Here's a good quick bed level test print to verify mesh compensation is working well. Print once with it disabled and once with it enabled.

Yes, I will. I will make sure that the mechanical part will do it's job too.

The HightMap looks like that now:
Very much the same warping which is not an surprise. The front right corner is a bit smoother now.
-
I have printed the "leveling_test" files. Once "normal" with the mesh compensation and once without it (G29 S2). I touched the lead screws from time to time so I was able to feel that the motors where rotating while the head was traveling when the mesh compensation was enabled. They did not rotate while the mesh compensation was off.

I have some more pictures, but I do not want to spam here.
The squares on the bed to look very good stick on the bed. I will print the big one again, lets see how that ends up now.

What is your printer a know type like a cr10 ?.
Have you tried printing on glass or a mirror ? -
It is a cr10 pro v2.
No, I tried PEI, Pertinax, FR4 and I have a sheet of printbite on my RatRig CoreXY. But this one is still "under construction". I had no chance to tune it in toll now. The CR10 have still to much problems.I'm not sure whether I want to try glas or not. I heard about enough problems there, too. And I think that the trend goes away of it, too.

Yes , another cr10s pro owner !!!!
Mine is a cr10s pro v1 , but with the bltouch upgrade .Now I know your machine a little better , how is the gantry on Z is it level and is the uprights level.
Mine was a pig at first I had to take to gantry apart to get the z axis to run level.
Just a personal one !!!! did you fit the duet in the control box.I use one of these :-

The portal was not optimal square and it was slightly bent to the back. I fixed that with some slices metal out of a beer can.
But I would not bet that it is perfect now.I printed a "holder", which are basically for "pins" on a rectangle:
I glued it right to the original mainboard and the expansion board to the place where the original mainboard was. That works very well.
I do not need access to the USB and micro SD card, so that is no problem for me, I'm happy with the network access. I swapped to many floppies, harddisks, SD-Cards in my live, I'm more than happy that I do not have to do that any more.Hahaha... I ordered the same product a minute ago while you edited your post.

Didn't the cr10s pro v2 come with one of these ?.
https://technologyoutlet.co.uk/collections/printer-parts-spares/products/carborundum-glass-plate?variant=32606698438735Or was it like the v1 a metal plate with a buildtakie clone sheet ?
-
I'm not sure whether it is getting better or not:
I will cut it again later and measure it again. I need to spend some attention to the paperwork for my accountant.

@peter247 said in Extrusion Calibration?:

It came with that plastic thingy glued on a alu plate, I guess to reach the same high as the carborundum plate. I tried to get that some month ago but I was not to get one of them. There where so hard soled out that even Creality in CN canceled my order after some month.
I ordered on from Amazon and I ordered a similar one from one of my preferred dealers here in Germany:
https://www.3djake.de/3djake/glasplatte-mit-chem-beschichtungIt seams to me that this is very much the same coating.
Btw: I replaced the original heater and the metal plate with a fine routed 4mm aluminum plate. The original one was to close to a banana for me. And I wanted to switch to a 240V heater anyway.

try the UK version :- https://www.3djake.uk/3djake/glass-plate-with-chemical-coating

Hahaha... well, as a German....
-
Hahahaha... they are from Austria!

I've ordered off them before , but thought they was Czech , but I think I was mixing that up with Fillamentum which is what I purchased.
( The niceshops group is an Austrian company )

This is my test of my cr10s pro.
My test file is 200mm x 200mm x 0.2mm , 30mm smaller and a second layer , 30mm smaller and another layer .
Had a little problem in one corner , but I think it was due to not cleaning the bed for the test and running over the remains of my last print. -
Looks good to me, well at least I can tell with this resolution of the picture.
I will get my glass surface in the next days, lets see what the results will show than. I have enough 3D printer for today.
