Lets do some testing
I will test all three cameras using both Kobra 3 Printers, My Computers USB ports

The working camera works with all cables and both Kobra 3's, my Computers USB ports. This means camera and cables are good...
The no light camera has no light with all cables and both Kobra 3's, my Computers USB ports. This means something is wrong with it.
The blinking camera blinks with all cables and both Kobra 3's, my Computers USB ports. This means something is wrong with it.

All cameras have video working, only LED lights are not functioning.]]> Roberts_Clif Prusa i3 and variants Thu, 03 Sep 2026 22:15:03 -0400 https://reprap.org/forum/read.php?406,896280,897716#msg-897716 Re: Anycubic Kobra 3 Combo https://reprap.org/forum/read.php?406,896280,897716#msg-897716

I have two Kobra 3 combo's and have connected the camera to both machines when one did not work correctly.
I switched it to the other Kobra 3 Printer and the LED still did not function.
Shenzhen Vedos Technology wants me to take a picture of the broken camera to prove it does not function.

Can anyone here tell me "How to I take a picture of a LED that does not work to prove to Shenzhen Vedos Technology that the LED or LED circuit is bad.]]> Roberts_Clif Prusa i3 and variants Sun, 23 Aug 2026 08:17:59 -0400 https://reprap.org/forum/read.php?406,897627,897631#msg-897631 Re: X axis moves toward end stop when controlling Y axis after marlin update? https://reprap.org/forum/read.php?406,897627,897631#msg-897631

It appears to be working correctly so glad this is over and done with.

3D Printing more of the Dino bag clips, and a someone that would like a few.
I have the speed set high enough that a clip only takes about an hour to successfully prints in lieu of the 3 1/2 hours

My room is still so messy that I can barely see the floor let alone the 3D Printer desk.
Though it is time that I get started back to my favorite hobby.

My Bowden Ptfe tubing got all messed up so I had to fix the tubing by cutting the crinkled ends to get tubes to stay in the Bowden clips.
Forgot how much fun it was to 3D Print!!!]]> Roberts_Clif Prusa i3 and variants Sat, 08 Nov 2025 09:00:54 -0500 https://reprap.org/forum/read.php?406,896280,896680#msg-896680 Re: Anycubic Kobra 3 Combo https://reprap.org/forum/read.php?406,896280,896680#msg-896680
If you load your model into Bambu Studio create all the Painted surfaces and save to 3MF file
Reload model into Orca Slicer 2.3.0-RC change to your Kobra 3 and filament profiles slice and save to USB flash drive then print with Kobra 3.

I have been looking for a users manual for Orca Slicer 2.3.0 or anything even close as to allow me to use the full potential of slicers.
Would be happy to see this in any form pdf, you-tube videos just would like to learn everything that can be done with this slicer.]]> Roberts_Clif Prusa i3 and variants Sun, 23 Mar 2025 08:50:02 -0400 https://reprap.org/forum/read.php?406,896280,896675#msg-896675 Re: Anycubic Kobra 3 Combo https://reprap.org/forum/read.php?406,896280,896675#msg-896675
If the Painted is in Object mode then they will have a place to select/change the filament.

Painted Object

Else if they do not have, then the filament will not change in this global mode.]]> Roberts_Clif Prusa i3 and variants Sat, 22 Mar 2025 20:05:00 -0400 https://reprap.org/forum/read.php?406,896280,896674#msg-896674 Re: Anycubic Kobra 3 Combo https://reprap.org/forum/read.php?406,896280,896674#msg-896674 Well thought is would work simply because Orca Slicer 2.3.0 RC lists AnuCubic Kobra 3 in compatible Printers lists.

I guess in a way it does work because it will print a mono print though not a multiple color model.
OK back to looking for a better slicer for my Anycubic Kobra 3 combo.

__________________________________________________________________________________________


OK today I tried again by placing 3 different color models on the same build plate. the results were great.
I printed 3 completely different color model gears of spiral graph on the same build plate at the same time..

So my thanks to Orca Slicer 2.3.0 RC for finding a way to get Kobra 3 combo printing in color..

now maybe I can figure a way to get it to print using my painted objects.
I do not believe that posting a Photo does any good just try to print as I have stated an you will see.

I swear I did a color print using Prusa slicer but could never could duplicate, now I will try duplicating this again.
Using this same method of printing 3 Separate color models on the same build plate.

The thermistor type defines the highest readable temperature

Eg type 1 thermistor [github.com]
The highest value in the table is 320

Next you have #define HOTEND_OVERSHOOT 15 // (°C) Forbid temperatures over MAXTEMP - OVERSHOOT
You need some overshoot so firmware can tell its over the temperature you set

so the max usable temperature is 320-15 = 305

This can be further reduced with #define HEATER_0_MAXTEMP 275
eg if your hotend has PTFE in the heated zone, you must limit the max temperature down to safer limits.]]> Dust Prusa i3 and variants Thu, 13 Mar 2025 20:51:04 -0400 https://reprap.org/forum/read.php?406,896644,896644#msg-896644 Trying tô increse maximum temperatura of the hotend https://reprap.org/forum/read.php?406,896644,896644#msg-896644 I have a Reprap Prusa printer, and I am trying to increase the maximum temperatura of the hotend, but did not succeed, yet.
I have noticed that in Marlin this temperature is set to be 250 degrees Celsius, but, effectively, It is just allowed to reach 235.
Is there any way to set this temperature higher? Maybe 255 degrees?

Is the configure h file the same from version to version or do you need to write a new one every update?

The Configuration.h file varies form version to version. I use Winmerge to compare both files.
Winmerge allows you to compare two or even three files then make changes to them and save any or all.

In fact it is probably time to see what the next version of winmerge has to offer.]]> Roberts_Clif Prusa i3 and variants Mon, 24 Feb 2025 07:53:40 -0500 https://reprap.org/forum/read.php?406,896541,896563#msg-896563 Re: Geeetech I3 Pro B problems after updating https://reprap.org/forum/read.php?406,896541,896563#msg-896563 tag1260 Prusa i3 and variants Sun, 23 Feb 2025 19:41:33 -0500 https://reprap.org/forum/read.php?406,896541,896561#msg-896561 Re: Geeetech I3 Pro B problems after updating https://reprap.org/forum/read.php?406,896541,896561#msg-896561

You will need to Post what firmware you tried to upgrade to. And does your Geeetech I3 Pro B still original hardware.

On this Link are a whole list of Marlin firmware versions pre configured for Geeetech I3 Pro B.

The micro steps Z axis are 1600 micro steps for trapezoidal rod T8x2 so will need to select your language and your Z-Axis micro-steps and should be close.
