Well my old elegoo Neptune 2 gave me a err5 code.
The hot ended needed some love and I thought why not give the whole printer a little refresh.
The goal is to install klipper, I have very little experience with such things but thankfully there is some great ppl online that share their efforts.
The Neptune 2 is similar to a ender 2 iirc they are almost like a clone.
One difference I have seen is mine uses a touch screen the other uses a knob.
Parts I have purchased are as follows
BIGTREETECH skr mini e3 v3.0
BIGTREETECH btt pi v1.2.1
Ender 3 lcd 12864
Mk8 all metal hot end.
I already had a direct drive extruder.
I really hope I can get this all figured out. I ordered the lcd screen in the hopes of there was a firmware that is already built for me to start with.
Any input or comments are always welcome I am very new to this and I am sure I could have got another printer but I have been really wanting to learn more about the pi stuff for other projects.
Here is the video I found that explains it pretty well
I would skip the screen completely to start. You can use kiauh to install klipper, moonraker, and mainsail and just interface with the printer using a computer connected to mainsail. You can also install mobileraker to control it from your phone.
Google your board model and klipper to get the typical pin assignments in one of the template files for your printer.cfg file. I run a raspberry pi 8" touch screen at the printer from the raspberry pi with klipperscreen installed from kiauh, but upload slices to it via moonraker on its web page and watch it with its webcam on my phone with crowsnest. Klipper works well. I run it on all my v1 printer and cnc systems now.
Thanks again everyone for all the helpful tips you ppl are really amazing.
Well my parts have finally arrived hopefully by the end of the day I have some kind of movement.
I guess the skr came with a screen so that’s awesome even tho I bought the ender screen already I am sure I will use it on some other project.
Anyways I will try and make some note to help any super noobs like myself.
Im using that board on my lr4 for x and z and a. different one runs the y because neither have enough channels on their own. Cool stuff you can do with klipper… And you can also use the lcd on the board too.
Thanks again I am getting excited. I never realized how much I rely on my printer. I have a bunch of prototypes to print.
Hopefully in a couple more hours I can get a test print done.
Alright well I found out what’s going on the firmware I put on must be for using bltouch.
So now I will see if I can reflash the firmware on the boards chip.
Are ppl still using bl touch ?
*edit it appears that a main feature of this is that you don’t have to mess with the firm ware. Very neat
oh yes you can use a bltouch. Just make sure you wire it correctly… or so I hear.
Yes… regarding the firmware changes, all you need to do is change the printer.cfg in the machine menu. If you click the blue thing in the upper left of your screen, a menu on the left side should appear. once you get to that machine configuration screen there is a list of files and one of them is printer.cfg. click to open and edit. then save and restart from that web page when done. There are template files for bltouch functionality you can add to get that to work. I can share what I use if you like, but my bltouch acts like the z homing sensor and you may or may not want that depending on your system setup.
Thanks for the info
I was planning on just using the zendstop.
I did as you said and managed to get the z pin working and the touch stuff hashtagged out for now. Just testing a benchi now.
I’m a klipper fan mostly for this setup part. edit restart, edit restart. It works awesome for printers and cnc’s. You can even use those old ender 8 bit boards with klipper… or multiples of them… just keep dual axis motors on the same board.
old computer power supply, RPI power supply, or 2/24v buck converter to 5V (3+ Amps). the rpi is likely to work best because they like 5.1V and other sources are sometimes 4.9V and the pi will give undervoltage warnings sometimes because of it, though my boards have been working just fine for a few years now. If using a pi5 series, you need more power and an active cooling fan.
Side note:
this is one of the reasons I ditched Octoprint because it would go crazy because of these voltage warnings and refuse to update. I forget the specifics of it, but it really was bothersome.
Perfect I got one ordered.
And I have just found a issue lol
So I brought the printer to work away from my home network.
I haven’t installed a screen yet and am looking into hooking my laptop up to it so I can do some test prints.
It’s seems like klipperscreen might be able to do this.
I am assuming I can add another ssid block into the printer config to have two networks I connect to.
I dont know that i have done much network setting from klipper or moving of the klipper system between networks. The raspberry pi has tools to do this over ssh or plug it into a tv via hdmi and grab a keyboard log in and add it that way. This is vague but hopefully points you in the right direction. A web search will get you the raspberry pi terminal commands to add network authentication.
