So I was correct? btlouch does "shrink" my bed surface? if so, how can I reflect that on Cura?
I looked at the probe you mentioned and I thought maybe to use an ultrasonic sensor, but then again I just to thought about the hassle of making one to work with the printer too much work..

Phaedrux

No it doesn't shrink your available area. It just means it can't get a height measurement from the entire surface because of the offset. The firmware will extrapolate the non-probed area though. It's still usable.

Your heightmap looks quite good so the bed is pretty flat and well leveled. Maybe tilted a bit down on the right side.

Your test print looks pretty good.

Your homeall and homez use different points to probe,

homez
G1 X45 Y25 F6000 ; go to first probe point
G30 ; home Z by probing the bed

homeall
G1 X116 Y116 F6000 ; go to first bed probe point
G30 ; home Z by probing the bed

You should change the homez X Y position to match the one from homeall.

You can adjust the G31 Z value up or down to get the nozzle closer or farther away.

@Phaedrux done!
Regarding the bed mesh area. so, my "extreme" points are:
start:
x - 43.5
y - 20

end:
x - 228
y - 230

that the nozzle and probe on bed. I tried to enter those values in the define area for mesh but it didn't start utilizing the whole available surface as I wished for. I did (228-43.5)/5 to get the distance between each probing but it didn't work

another question I had, so the paper thickness I'm doing the manual bed leveling is 0.2mm. do I need to reflect that in Cura? I tired to edit the default profiles there but I didn't see anywhere to enable this option to edit any values (it's grayed out).

at the same momentum (while you're online :))
Is there a way for me to add custom buttons for the web GUI?
Like adding quick buttons to disable all motors, extract and retract probe, go to specific locations on the bed, basically anything else that would be nice and accessible if needed?

You can take account of that in the G31 value so that it's just applied all the time. Or just adjust the G31 based on how much baby stepping you need. Nothing needs to go in Cura.

You can create macros for any command you want and they will show up as buttons in the web interface more or less.

For your mesh grid you can use P instead of S, which would specify the number of points to probe rather than the spacing.

M557 X15:215 Y15:195 S20

Getting the largest area probed will require some experimentation. If you're going over the edge on one side, bring it in, if you're not going far enough on a side, remember that you can't go farther than the nozzle.

Hey Guys,

So far so good I'm able to print in great quality (I'm using fafts in all prints and it's great.
I would like to add a webcam to the web GUI, is that possible? I heard that I can do that with pi but I'm already using the Duet so is that a capability?

didi767

@Veti Bummer.. I thought it would be much more simple.
on the same momentum :), is it possible to integrate the Duet with Cura? so I don't need to manually upload it each time?

jay_s_uk

@didi767 yes. theres a cura plugin available in the market place to allow uploading and automatic simulating or printing of a file

didi767

@jay_s_uk It says only Ultmaker printers, but I can't connect my Ender 3 Pro even though I'm using the Duet board?

jay_s_uk

@didi767
thats the plugin on the market place under community plugins.

Its then configured under the extensions menu (after you close and open cura).

In there you add the printer IP and password if you have one set.

The printers then appear in the bottom right hand corner button

didi767

@jay_s_uk Thank you so much for the detailed instructions! unfortunately I still don't see this in Extensions tab.
I installed it via the marketplace and even tried to installed it manually (I created the path using the source files), but nothing (and restarted Cura , of course each time)
using Cura 4.8

resam

@didi767 the version straight from GitHub uses a different settings store. You can go to "Manage Printers" in the Cura settings and when you select your printer there should be a "Connect Duet RepRapFirmware" button.

didi767

@resam You're right, not it appears under the printer's settings. Thanks!

Hey guys,

quick question, I had few prints ruined because of filament jam and runout. is there a simple solution to monitor that and pause the print so I can fix it instead of losing time and prints?

thanks!

Veti

@didi767

runout. either get a filament sensor or check that you have enough filament before the print. the slicer will tell you exactly how much filament you need.

for jams.
the hotend of the ender has a probem. the ptfe tube does not fit tightly on the nozzle by default.
this causes filament to squeeze out and cause problems.
there are guides on how to fix this. e.g https://www.youtube.com/watch?v=7tCxO17XZtw

the ender extruders are suboptimal. consider getting a bmg extruder.
triangelabs does a special version that fits on the ender 3 directly

@Veti
I was researching a bit on the two (the ranout and jam) so the extruder you mentioned supposed to alert me whenever a jam has occurred?
I had an issue with the spooler getting tangled and messed up the print, so I was thinking about to do something with optical sensor to detect if there isn't any filament motion going on, are you using a similar solution? do you even get tanglement issues while printing from time to time?

Hi guys,

long time
I have a quick question if I may.
I became pretty familiar with 3d printing by now, all thanks to you!
I was wondering if there is a more efficient way for me to perform bed leveling instead of doing it manually?
is there a script that can move the motor to few places and then I just swipe the paper?
or is there a better way to do so?
and is it still necessary even though I'm using BLtouch? isn't it compensating the height differences already?

Thanks!
