3d printer help.

[Chuppster]

So wait, as far as the bed cable it is four wires. Would that mean that two of them are for actually heating the bed and the other two are basically a thermistor that tells you how hot the bed is? If so couldn't i just cut the plug off the end, use the two heater wires and just use the screw plugs on the motherboard to hold those, and then solder the two thermistor wires to a two pronged version of a JST plug that plugs into the bottom left hand corner of the motherboard?

That's what I would do.

Cool just wanted to make sure that would work. Thanks!!

So it has been a while sense i posted so here is what i got. I am building a delta 3d printer. I have finished the printer frame and am just starting on the gantry carts and motors. Here is a picture of the printer so far, their is a 36" ruler on the left of the printer for scale. View attachment 146303

Here are the electronics i am planning to use, please let me know if you see anything wrong or see anything that you think won't work well.

Hotend- https://e3d-online.com/v6-all-metal-hotend

I am upgrading it with this- https://e3d-online.com/volcano-upgrade-kit

What type of nozzle should i get? Does it matter at all what material it is or...

Extruder- https://e3d-online.com/titan-extruder


Here is where I am getting confusing

https://www.aliexpress.com/item/32980090169.html?spm=a2g0o.cart.0.0.1de93c00WmQLOR&mp=1This is the board i am gonna get, so does it come with drivers? Do i need drivers? If so which option do i need to choose for it to come with drivers that will work with these motors: https://www.oyostepper.com/category-6-b0-Nema-17-Stepper-Motor.html

Are those motors good quality motors? Would this screen work with it?

Thanks, i am sure i will have more questions but thank you!

I also have simialr question as you.

I also have simialr question as you.

Regarding what? Are you planning on building a printer?

Thanks!

 

[xihukouking]

yes, i will build my 3d printer recently. I have bought 2 stepper motor, but i not sure it is fit for 3d printer or not?

Depending on your configuration it could work. Have you ever built a 3d printer?

I want to start a business of 3D printing because 3d art is in trend right now. I saw on Facebook and Instagram, that many people are using the 3D printer machine and it also uses office work also.

So i need to figure out a way to extend the wires that come from the Titans NEMA motor and the wires that come from the E3D Volcano (both the thermistor and the heater cartridge). Could i just solder on more wire in the middle of the wires and if so what gage should i use. If not what options do i have? Thanks!

 

[IcedStorm777]

For a heated bed would it be better to run it at 220v at 800 watts or 220v at 1000 watts. It is 500x500mm. I assume i would be using 220v as my setup is 24 V. If i do this i assume i would need to get a more powerful power supply? If i did this would i still run my heated bed through the motherboard or would i just run it straight through the power supply?

If you match the wire guage that you are extending, cutting them and splicing more wire is just fine.

A 220v heated bed will run off 220v mains power. If you are in the US it is unlikely you have access to that in your house, unless you have an electric stove in the same room as your printer. Running it off 24v it'll never heat up more than a few degrees.

Gotta. So than would running it off of the 24V 450W version work? I just didn't know how much the watts mattered. This is what i am talking about. https://www.aliexpress.com/item/328...chweb0_0,searchweb201602_4,searchweb201603_53

As I said, you can't really run a 220v heated bed of a 24v supply. That heater is meant to be plugged in to mains (usually through a relay). Are you in a country that uses 110vv or 220v?

Wattage is the amount of power that the bed draws. More power means it can heat up more and faster. Voltage is the amount of volts required to reach that power. Your power supply (or wall outlet/relay) needs to support the power drawn by the bed. So, if you want to run a heated bed off a 24v power supply you will need to find a heated bed that is set up for 24v.

I am in Colorado (USA) so i am pretty sure we run on 110v. So would the 24V 450Watt version of the one i linked work considering i am planning on using a PSU that is probably 700Watts? So basically, the bed will plug into a relay (which is also called a mofset right?) and that will plug into the motherboard? Thanks

Relays switch mechanically, MOFSETs switch electronically. While they both do basically the same job, you don't want a relay switching on and off for a heated bed (they can pulse on and off quite rapidly.)

Here's an example of what you probably want;

Literally the first one I came across, so it is NOT an endorsement of this particular one.

Some of the newer (better) boards can handle this kind of amperage, but personally I like to use a daughter board like this "Just to be safe"...

They make "solid state" relays, and those are used for AC (wall) power. MOSFETS are used for DC power (what comes out of your PSU). So, you'll want a MOSFET and a 24v heater if you are running a 24v PSU.

If you're doing your own printer, you really ought to be doing a lot of research. Maybe start by watching a ton of Tom's videos?

I second @Chuppster recommendations and would add maybe look at just buying an Ender 3 or 5 (make sure it's a genuine product) and start with that. With a few upgrades (which I see are now are "standard" on the ender 5 pro) is all you need to take a $220 (ish) printer and turn it into a real workhorse... Those few upgrades (Extruder, tubing and connector updates and a few printed parts (spool holder, filament guide) will give you a taste of what it will take to do one from the ground up.
