you can set it in the menu to trigger between 1 and 63 amps, though I wouldn't recommend to use this above 40 amps, as its not a well known brand and at that much current you risk to set something on fire

I dont remember exactly what I used, but PET has a melting / printing point of around 260-260, so I think something like 220 should do it, its quite easy to adjust on the spot. I stopped doing it though because of the smell, if you have some outdoor space its fine, but indoors its not worth it. It was printing fine with this filament but same problem with the smell when you print as well

Yes you can

debian

you probably played around with the options, do this: get a clean copy - git clone github.com/Klipper3d/klipper, make menuconfig - and only change architecture to - rp2040, then press Q for exit and save, then make. and it will generate the uf2 file, I have done it many times.

@@CNCTinker it was because i had bootloader selected, need no bootloader for klipper.uf2. :D

yes its the one you can see in the video, its my main board with the stepper controllers, temps, heaters, endstops. I dont use a separate rpi 4 although I have one, I just use my laptop with linux instead of the rpi 4. usually people run klipper off and rpi 4 that connects via usb to this controller board. I use a laptop instead of the rpi 4.

i have read so much forums that says it's not capable of running 3d printer firmware

it depends on the firmware. marlin runs on small mcu-s like the arduido, or esp32. it could run of this as well but its not suported last time I checked. klipper on the other hand need a full fledged os. so it need a pc with linux, people usually use rpi3 or 4 cause they are compact. problem is rpi3 or 4 have just a few hw connections around 12. for steppers temps heaters etc you need like 20 so you use a separate mcu and board, it could be a pico like me, arduino anything with more pins and you connect this to the other one.

i got it bro now thanks alot I learnt new thing from u I can use it on a dead phone now i don't even need pc

@theflamecoreguy7929 well a phone it is a small pc :) it runs an os, should have said any gadget cause you could even install a custom os on a router and run it on that. what phone and os did you use ?

I have in the description a link to github where you can find high resolution image

@@CNCTinker I followed the link and the image resolution is low.

ok then you can install EasyEDA, its free, and use the project file from the github,, you will have unlimited zoom

@@CNCTinker Raspberry Pi power and stepper motor logic (VDD) from USB or external source?

I use the power from the usb connector of the Pi, it doesnt use much, around 35ma. I did add a dc-dc converter 5v for the servo cause that uses more current, so I should power all from that

I had no issue with it, but you can use solid solder traces, or a fatter wire. the distance is not big, I dont remember the gauge of the wire but its a similar size with the wire that comes with the heater

yes 4.7k its kinda standard with these 100k thermistors and 3.3v adc. It must correspond with what you set in the firwmare or it will give wrong temp. try to measure the voltage on the thermistor and check with a datasheet of the thermistor to what temp it corresponds, and what the firmware reports to find if the error is from the circuit or firmware.

@@CNCTinker Solved the problem. For WeAct rp2040 and similar boards, it is necessary to solder the VREF jumper. In order to use the ADC reference voltage from the main power supply of the 3.3v board.

sorry for the late replay, comment went to spam because of the marlin version with points, maybe try to keep pressed the boot button while connecting, some board miss a capacitor

thank you! 4.7k resistor. its what most firmwars use as default to calculate the temperture

they are not easy to build from scratch with no functional 3d printer to make parts, I wanted to make one without using another 3d printer like most people do

@@CNCTinker so can we use micro SD card to print, just like marlin, because we can't just attach laptop whole time. In marlin with Arduino mega and micro SD card module required, as I can see you used just one pi pico is there any some special requirement for klipper like pi 4 or 5 to just print using micro SD card.

yes most people use a raspbery pi 4 or 5, instead of a laptop. you dont need an sd card as with marlin, since the raspbbery pi its a computer with s and storage, you just send the file to it.

@@CNCTinker pi 4 is expensive, can we have cheaper options

Orange Pi 3 LTS its a bit cheaper, or use an old laptop/pc if you have one. even a 10 year old laptop will run faster then a pi if you want cheap

no ide required, check my klipper linux install video. you download klipper from github, open a cmd and type make menuconfig, select rp2040 as the cpu then make and copy out/klipper.uf2 to rp2040 - if its new it shows as storage. that is all. also check www.klipper3d.org/Installation.html you also need for this either a rasp pi running linux, or a virtual machine running linux on your laptop/pc. klipper doesnt work on windows, and last time I checked rp2040 is not supported by marlin

it actually charges even when its cloudy and you dont see the sun

I have a newer video with the schematic that also has link in the description, check my other videos

yes, I will post it soon

@@CNCTinker do it bro its not clear and not working on here your videos are very poorly documented

@theflamecoreguy7929 ok, I posted a new video on how to do it, hope it helps

@@theflamecoreguy7929 Everything works, everything is installed. It just takes a little figuring out.

​@@CNCTinkerthanks a lot bro i will also upload my cnc project very soon and your name will be on it ❤️ 😊

actually I do have "proper" belt gears, I just found using a pom wheel or just spacers works much better :) its very easy to remove the belt, you just slide it, and as long as you align them properly, the belt doesnt fall. and the project its intended to be very budget, my last corexy was getting to expensive 😅

If belt is not falling of idler is alright and printer will print ok I have similar solution in my prusa on x axis where idler is only bearing and it works fine.

hi, I'm not sure rp2040 it is fully supported, 2 months ago they did add a HAL - hardware abstraction layer - for it in the marlin code, so it might work but maybe not with full capabilities yet. you need to compile it in the same as on any ohter mcu. you eithet use arduino ide or visual studio code, and edit the config file and select the board with that mcu

@@CNCTinker many thank, bro! it is my first time. i can saw a rp2040 in to src folder. let me try.

check the previous 2 videos, I show there

sure, its comming next

last time I checked no, though it says on their website they are working on adding support for it

@@CNCTinker thanks that very helpful

sorry I don't have an expensive one

I'm working on a new design, smaller

klipper

yes you can, they are almost identical, the 2208 has a bit lower specs but unless you go high performance there's no difference.
