Is the thin wire enough for the heated bed? Im worried it might not be able to carry 10a

@CNCTinker 20 күн бұрын

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

Tell me, do you have a thermistor connected via 4.7k? Does it give me an incorrect temperature?!! The connection scheme of btt scr-piko on github is somewhat different...

@CNCTinker Ай бұрын

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.

I just installed it following a surge in the electrical network (250 volts) which damaged the boiler's printed circuit. I set p01 to 230 volts and p02 to 225 volts but I still have 250 volts supplying my boiler

@comendadordavila Ай бұрын

nice project! what divider resistors are you using on thermistors, for ADC?

@CNCTinker Ай бұрын

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

Why dont you just build like ender 3 , prusa mk3 those are far better designs.

@CNCTinker Ай бұрын

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.

@CNCTinker Ай бұрын

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

@CNCTinker Ай бұрын

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

make a clear video on how u flashed the rpi pico man youre not showing how u programmed all of it what ide u used

@CNCTinker Ай бұрын

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

Good day. I have some success with rp2040. I am using a clone of RP2040 WeAct. 1 - There are subtleties with the klipper firmware. 2 - The board has two additional outputs, an additional button and a neopixel LED. 3- I got gpio0, gpio1 working without any problems! I determined the functionality of the board for myself: 4 uart drivers, 5 controlled loads (mosfet) , 3 temperature sensors, 3 end caps, 7 spare pins (for uart or SPI or I2C + encoder). I will keep you informed of further progress.

Nice project, very budget. I see the idler is a bearing with pipe maybe some like that and it don`t have any holding for a belt so toothed belt can easly fell of the idler. Keep building I`m waiting for next videos :)

@CNCTinker 4 ай бұрын

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 😅

@bluemat. 4 ай бұрын

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.

@CNCTinker 4 ай бұрын

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

how do you fix the origin problem ? for example cura has it's origin in the front left side of the printer, if you don't mirror the part it will mirror the print. i mean yeah, you could just use another slicer program but i was wondering if there is another way

@hansmortensen5668 5 ай бұрын

A word of advice, you will likely find that that small motor will not have enough torque to directly drive the filament, but you could gear it down to increase torque but this will add backlash in the gears. But your boden tube idea will probably work well.
