Firmware 2.7.2.1 Changed G9111 startup macro

It used to set hotplate temperature, wait for that to complete. Then heat nozzle.

- Now, it sets the temp to 250, then loads the first filament.

Is there any reason it sits there at 250? Are we stabilizing the nozzle heater?
I'd like an 'M140 S140' to get the temperature down.
So, after the filament is flushed, set the temperature to 140.

- While waiting for Filament to load, the hotbed could be warming up.

I added to machine gcode:

M140 S{int(first_layer_bed_temperature[0] +10)} ; hotplate warmup is [first_layer_bed_temperature] + 10 is {int(first_layer_bed_temperature[0] +10)}

G9111 bedTemp=[first_layer_bed_temperature] extruderTemp=[first_layer_temperature[initial_tool]]

M117

But, I guess the G9111 quickly reset the printer. Can the G9111 kick off the non-blocking heating of the hotplate first thing?

Is there any way to do this where the printer isn't so single threaded?

Kobra S1 Best Feature! [Sarcasm!]

I love it in the dark of night all alone nothing can be heard except discordance of rrrrrrnt, rrrrnt, rrrrrrrrrrrrrnt, rnt of 3d printers. You break open an S1 to replace the nozzle from the 0.4, to the beastly 0.8. You take the printhead cover plate off. Flip the nozzle lock lever, reach behind and unfasten the heater thermistor jack.

Instant darkness.

My garage for a flashlight.

- Is this the joke reddit?

Hmmmm None?

Heat tower 220 to 250 with PETG and 0.6 nozzle.
I think it needs more model fan.

But I’m horrible on these tests. To me, it’s a speed/temp thing.

I don’t consider micro strings bad really. Sometimes 250 lays it down.

I raised my camera for 3 shots, then took left/right.

Is this normal or Do ai have a screw loose?

The heatsink for the Throat of the nozzle wobbles.
Is this supposed to be tight to allow thermal conduction? I’m not going to run the printer in a vacuum so I didn’t care.

But the firmware likes to cut the filament a lot and a 3 mm long piece got stuck inside a crevice between the back of the heatsink and the mount.

A few weeks ago I did find a small screw. And there is a clicking sound when the hotend moves quickly. That may all be unrelated.

PETG causing shrinkage/ warp

PETG shrinking causes part warp

Here at the very ends (of the build plate or the part?) the forces lift it as it cools.

I have 15 or 20 mm of brim at 0 separation.

Are there any ways to add mega brim in places? Change the first layer to .28, have bed at 82, then pause after first layer with a 65 bed plate?

I have 65 bed temp here. 60 even holds just like this. So it adheres well. But maybe at the end of the plate, at the high stress of the long part, it all adds up.

Suggestions?

Also, I was thinking to just put a 5 mm vertical slice at the plate a few mm beyond the second rim. That would eliminate the horizontal pull on the first 20 layers or so?

I have the chamber fan running at 42% to avoid clogging, which I just got because somehow the 4th bay was used instead of the 2nd. That was PLA. It didn't like the heat.

2nd reprint and it correctly grabs 2nd bay filament.

(From the slicer. Both Kobra S1 and S1 Max randomly choose filaments unless I select filaments multiple times, wait for it to randomize, select it back again - I suspect there is a filament server somewhere on the moon and it takes awhile).

\- how to fix warp?

\- is stress relieving cuts a good choice?

\- slicer ace pro and ace pro 2 sync delay happens.

800x800x800 model I wish to slice with AnycubicSlicerNext on S1 Max 350x350x350 multiple prints

I made a doghouse and I can scale it prior to, or after slicing (I guess).

I guess I need 27 parts. I can slice with OpenSCAD, but if the slicer can add dovetails and dowels, that is even better.

If I make 27 parts, How do I Then add a connector? I want to piece together all parts and have a big 33 inch object.

Too BIG to print

Can I temporarily move ACE Pro 2

Can I move an ACE Pro 2 from my S1 Max to my S1 to see if the S1 can communicate with it, then move it BACK to my S1 Max and everything works?

I know the iPhone/Android/Slicer software communicates with a System server and I don't want my S1 max to reject it's ACE Pro 2.

I ask this because almost a year ago I bought an S1, then an hour later an ACE Pro. Then a week later an Anycubic 3 V2 Combo.

I could have swapped ACE Pro around accidentally. The S1 worked towards never being able to see an ACE Pro again. Gemini says it could have firmware set to reject an ACE Pro since some database might list the S1 as NOT an S1C.

I don't want to destroy my S1 Max by doing something users are supposed to know but don't.

And if the ACE Pro 2 works with S1, I can buy an ACE Pro 2 to replace the ACE Pro. Then have two ACE Pro on my AC 3V2.

Unless, I can't.

How to use PolyCarbonate?

I have a new spool. It is clearly wet since the bag isn’t a vacuum anymore.

Anycubic says 80C for 9 hours. I found a sunlu FilaDryer S2. But it only goes to 70.

Do I take my s1 max outside and use the chamber? This way the BPA goes outside?

Is there a good magnetic model that attaches to the back of s1max so I can vent to out outside? Via a vertically opening window? Then I can dry it in the printer chamber with everything in the inside of my house? Do I use dryer hose? Or does MMA/BPAs, whatever react with that?

The printer gets hot enough to print PC, but the user really needs to know what they are doing to use this filament.

Where does this belong?

After a print I found THIS on the printbed.
It fits the smallest wrench included.

It is a very small screw.

Maybe a clue, maybe not, the printer makes/has been making a clicking sound when , i believe, it moves in the X direction quickly. The movement is very tight on this axis. I can’t replicate the clicking sound manually because i can’t push it fast enough. The sound happened the second or third day. The screw fell out today weeks later.

But, focus on that screw first. It probably holds on the X axis clicking sounder.

I want to dry TPU 95A in the ACE Pro 2, then set the dryer for 24 hours. Disconnect the data cable from the S1Max.

Have a wedge that fits in the ACE Pro 2 opened lid allowing a seal (like the lid isn't opened), Thread the filament through a small slot in the wedge. Then feed the filament as if it came from the external reel.

I don't see any quick prints with TPU because the speed is down.

I would need an axle to free spin the reel.

Are there parts out there for this, or a better way?

I have a nice attic which goes from freezing to 100°F. Essentially outside but never wet. There is space for many printers.

I have a basement. Same humidity, but much closer to household temperatures. But 5 feet high.

I use inside currently. 3 anycubic printers. But the space is tight, poorly lit, certain people complain when printing.

Is an attic fine? Do the printers rust or is everything coated? Should I build a “room”?

I hooked up Ethernet to my k1max and I don’t see:

Source:0.0.0.0:68

Destination:255.255.255.255:67

For DHCP discovery.

The display reports nothing connected.

Could a cable have disconnected? [Essentially, my home is upside down compared to it’s origin. That was a joke].

Is Ethernet implemented yet? [I assume the OS easily handles different interfaces.]

I put the printer a long way from the other printers. WiFi works fine, but just not 5Gb, or 1.

This printer is quiet! Wow.

Do I just toss my KS1? That’s how good the ks1 Max is!!! [I’ll keep them all.]

Did the Beta testers rate this printer as top of it’s class? Mr fish 98?

I love my KS1. I like this much more.

On to testing it’s accuracy!
