AI Help

It sounds like you have tried several common troubleshooting steps already. If you are still experiencing issues with your 3D printer, you may want to check for clogs in the hotend or extruder, ensure that the filament is feeding smoothly, and confirm that the nozzle is at the correct temperature for the filament being used. You may also want to double-check your slicer settings and make sure they are optimized for your specific printer and filament. If the issue persists, you may need to further investigate the hotend assembly or consider replacing any worn components.

When you yanked it out cold did the filament come out nozzle shaped, small cone on the end, or did it stretch, if it stretched try colder

Tips for better first layer success

The first layer is quite literally the foundation of a successful print. These are some of the things to keep in mind:

Wash your print surface with dish soap and water, refer to ?bedcleaning .
Ensure your printing temperatures are appropriate. For PLA, the ideal bed temperature is 55°C-60°C. If the lines appear to come out "gummy" and forms clumps, raising the nozzle temperature may help. Calibrate your nozzle temperature by printing a temperature tower. Refer also to ?platemps .
Relevel your bed and ensure your nozzle distance is equally spaced at each corner, refer to ?paperlevel . If your printer is equipped with a bed meshing probe such as a BLTouch or CRTouch, make sure your Z-offset positions the nozzle close enough to the bed, refer to ?z-offset for additional information. If your printer has automatic Z-offset calibration, make sure the nozzle is clean while the calibration runs.
You can confirm that your leveling and Z-offset is correct by observing your first layer extrusion by printing a full layer test: Printables, Thingiverse Refer to ?leveling for help with the interpretation of the results.
Ensure the nozzle is not colliding with the print. This usually presents itself as loud noises and layer shifting. Some causes may include overextrusion, insufficient cooling, mechanical Z axis issues, or insufficient Z hop
For warp-prone materials such as ABS, Nylon, Polypropylene and others an enclosure is recommended, ensure ambient temperatures are high enough (40°C+) and stable. Consider using a specialized bed adhesive.

After all this, you might need to tune your z offset if its starting to print too high up

orchid boughBOT Jan 3, 2025, 3:59 PM

#

Z-offset

Where your printer thinks the nozzle is

The z-offset is the distance from the tip of the nozzle to the trigger point of a bed sensor.

Setting your z-offset correctly ensures a good first layer squish and proper adhesion to the build plate (assuming its clean, see
?bedcleaning for more information). See
?leveling for a good representation of how the first layer should look like.
If in doubt: Refer to you your specific machines documentation.

For the Qidi X series printers: Adjusting the z offset from the Fluidd webinterface breaks it. Always set the z offset from the printers screen.

nimble slate <@406971626836721664> lmk what youd suggest

This is still kinda weird🤔

#

Rest works?

#

I guess you have no filament loaded?

#

How high does it start?

#

4 mm should ne plenty usually. Can you move the probe mount up/down?

#

Oh and I spotted an error in the start gcode🙈
It should be M206 X20 Y5

#

Not X5

nimble slate Jan 3, 2025, 5:49 PM

#

There is filament loaded

#

It just jumbled up

#

Didn’t come out straight

#

OK I’ll update it and record it with a video @untold belfry

nimble slate Jan 3, 2025, 6:29 PM

#

@untold belfry

#

I tried lowering with z offset but it’s not working. Is there something in the start code we can put in to lower it back down?

#

Was it supposed to go around the bed and level itself first?

#

Because it just went there and started the print

untold belfry Jan 3, 2025, 6:34 PM

#

Huh?

#

Thats...curious to say the least

nimble slate Jan 3, 2025, 6:39 PM

#

Sorry which part

#

That it doesn’t go around and level first?

#

Or the whole thing lol vaulthah

#

Well I’m assuming this has something to do with the start g code right?

#

Since it wasn’t doing that before and we changed something, so is it possible to remove the Z axis component there and maybe it will go lower?

#

Or is there a way to leave the Z blank and tell it to use auto bed level sensor and input that value in

#

Like idk set Z = missing

#

Run auto bed level and store coordinates for X1 Y1 and Z1

#

Set Z = to Z1

#

@untold belfry

untold belfry Jan 3, 2025, 6:48 PM

#

If you check your video (from before) it homes z with the probe, doesn't it?

#

Did you add the probe or did it come with it?

nimble slate Jan 3, 2025, 6:49 PM

#

I’m not sure if it homes the last two times I printed

#

Probe and everything else is stock to the printer

#

No hardware or software mods ever

#

I’m pretty sure it didn’t home this time though

#

I think it just went straight to start printing

#

I feel like we were pretty close when it was just missing the X axis by a few millimeters

#

Can we just tell it to go in by X=10mm and not change anything else or does it not work like that @untold belfry

untold belfry Jan 3, 2025, 6:57 PM

#

nimble slate Can we just tell it to go in by X=10mm and not change anything else or does it n...

Yeah we can roll back the last change I guess...

nimble slate Jan 3, 2025, 6:59 PM

#

Kk so to add the M206 line?

#

Kk

#

And this should make it auto level first right?

#

Or simply go into the print

Hey sorry for the delay! @untold belfry

#

So I tried the print it’s starting and looking better but it doesn’t create the mesh across the bed before it prints

#

#

It’s starting to print but not sticking well or something idk

untold belfry Jan 5, 2025, 2:58 PM

#

nimble slate It’s starting to print but not sticking well or something idk

Whys it not doing it? feelssobman can you connect the printer via usb to a computer?

nimble slate Jan 5, 2025, 3:00 PM

#

Idk I can try

#

What would I be looking for to see if I can

#

It has a micro usb port

#

#

How would I know if it’s connected correctly

#

To the PC

untold belfry Jan 5, 2025, 3:12 PM

#

nimble slate To the PC

You get the "Pronterface" software which gives you a terminal to send gcode and see the printers answers, basically

Why you should put tape on your USB cable

Your device might try to feed power to your printers motherboard, causing all sorts of problems from loss of connection to a destroyed board. Putting tape on the 5V pin of the cable can be an easy solution.

untold belfry Jan 5, 2025, 3:12 PM

#

Consider doing this to the usb cable, no clue if your board is protected from backfeeding power into it

nimble slate Jan 5, 2025, 3:16 PM

#

Oh I used to have octoprint running it for a year back in the day

#

So I think we’re just going to send it lol

#

Ok so download pronterface ?

#

Should I just set up an octopi and connect like that?

As long as you can get a console to send gcode directly

nimble slate Jan 5, 2025, 6:52 PM

#

I think octopi does that let’s see I’ll check in when I can. Thx so much for your help!

Are these issues probably due to bed not being level?
