[2016 version] How to set up the Marlin firmware!

Setting up the Marlin firmware can be quite overwhelming if you haven't done it before, but most of the settings are fairly straightforward if you know what they mean.

2020 and still helps. However, I think its time for an update!

[@4STEVEJOY34]

6:02 Boud Rate 6:29 Motherboard (Ramps) 7:39 Thermistor 8:33 Safety etc (Thermal runaway) 11:03 End Stop Info. & 16:13 12:00 Z Prob 12:20 Motion 13:14 EProm Settings

[@gunnarprinter]

Still relevant in 2022. I bought a V1.03 lulzbot mini off ebay and needed to upgrade to a motherboard compatible with LCD interface. The stock motherboard was a mini Rambo 1.1b and I needed a 1.3a. Lulzbot wanted to charge $200, but I could buy the same board from Prusa for $130 (somehow shipping to CA from CZ was less than shipping from ND). The only catch was that I needed to flash brand new firmware. Because this board came with Prusa firmware already installed, Cura alone was not enough to connect to the board and update firmware. Arduino was the only way and this video showed me everything I needed to make it work. Thanks Thomas!!!

[@pwerlvlin]

it's late 2020 and this is still helpful! Thanks brother!

[@cna9708]

Finally got the time to tinker with the printer and your videos help a lot, it is all I need to get started again and it covers everything I need. Really removes a lot of painfull research and testing. Many thanks!

[@spikekent]

Perfect explanations, presentation and delivery as always. And, I always learn more from you with every video. Keep up the great work Tom

[@ScottLahteine]

That was a very good and concise explanation of the configuration process. We've got a boatload of changes coming to Marlin 1.1.0 (which will have another so-called "release candidate" out shortly) and it would be great to see an update on configuration and some of the new features when it's released.

[@NerdlyCNC]

Great video! Love these in depth explanations.

[@onecarwood]

Thanks Thomas for this video I really needed it and probably all the others that you mention in here. I am learning more from this channel than I have from everywhere but the Docs! Your the best and really appreciate what you do. When I am able, I will make sure I hit you up with a little green! I finally picked up my first Printer ever because of you and the fact that I have this awesome resource. You are the best on KZbin! The Duke of 3D.

[@TacBlades]

Just made and working build of Marlin 1.1.7 for the CR10S and works amazingly well :)

[@chrisjericho7123]

Did anyone else time travel and come here from the 2014 version and see Tom get older and better?

[@MrWaalkman]

Actually, I time traveled an additional year to respond to your comment just... now.

[@PvtPrivate]

I highly recommend Repetier Firmware for delta machines, it has better delta calculation giving smoother prints and higher max speed.

[@christophergrove4876]

Just as an FYI to people. Marlin IS available for the Monoprice Mini DELTA machine that I am using. In fact I have Marlin running on it now. The fork is "MARLIN4MPMD". It saved my sanity.

[@coatduck]

16:14 Can we make this the new 3D printing gang sign please? This is perfect and I'm going to use this trick all the time

[@fntsmn]

Ahahahaha nice idea :D

[@neoncyber2001]

I think the "POVRay" crew already has that one. ;)

[@coatduck]

That's fair. We'll just steal it.

[@n70tonka]

Question when I open it. It doesn't have all the tabs as shown in your video?

[@marcellemay7721]

Super video. Very informative. Helped me very much as to what all parameters mean in the firmware and how to tweak them. Thanks

[@parasox6203]

Thomas, great informative video. I'm building a new printer soon and really appreciate the time you put in to these videos.

[@randomgenerated9742]

Awesome and helpful video, although i couldn't help but notice the sequence of Chinese in your shirt is supposed to be "今日娱乐节目".

[@Dust599]

Dont home any axis before checking endstops are working with M119 commands

[@goldbunny1973]

Good advice - and always be within 3ft of the power off switch. First machine, Repra i2, crash crash crash crash, and now I have a drone - crash crash crash....

[@sspndrby]

what software is being used to send these commands?

[@davec3275]

When updating the config for the latest version with entries from the old firmware, how do you account for differences in options? The firmware released with my printer is missing some options that are in the latest version, and vice versa.

[@askquestionstrythings]

I hope to see a 2020 version with Marlin 2.0 this year.

[@AlansWay3DPrinting]

This was an excellent video with great explanation of the config files. Thanks.

[@ozzloy]

this is exactly the video i needed! thanks!

[@KAFA2020]

Dear respected sir, Hope you are in good health with success and happiness. I am really happy for your awsome works. Two days ago, I bought a RUMBA control board for my large scale 3-color 3D printer. But I am facing some problem to install marlin software. What could be the differences if I use RUMBA control board and 3-color extruder? Please sir, reply me.....

[@icsamppl]

I much prefer the Repetier firmware, also comes with a nice web interface configuration editor so no sifting through config files.

[@thediscoman2001]

will that work with ramps 1.4

[@1984TK421]

Would you please do a video on the mks gen l v1.0 firmware for tronxy x5s configuration. I'm having trouble with this? Thanks

[@TeddyReight]

Very nice walk though Tom. Will you be doing a Repetier walk through? I'm interested to hear you thoughts of PID VS Dead Time Temp control.

[@animadoarts5123]

*Pls HELP: Want to adjust z home position to -0.1*, *Im not using any probe sensor* i do G28 M211 S0(so i can go below 0) Adjust my z axis(let say I want it to be -0.1, as we know sign should be opposite so +ve 0.1) m428(to save all offsets) m500 m501(shows i have successfully saved it X:0 Y:0 Z:-0.1) *but when I home again I expect it be -0.1mm below the actual position. which it doesn't. The nozzle stays at 0,0,0. But if do M501 it still shows my nozzle position to be at X:0 Y:0 Z:-0.1* *why is the nozzle not going down by -0.1mm even though it has been written on EEPROM*

[@delgueda]

Hello Tom, Great video, as always! In your previous version of this video guide you mentioned that you prefer not to use PID when you're controlling the heated bed with a solid state relay (for example for powering a silicone heater with mains voltage). Do you still recommend using the bang-bang method in such cases?

[@tezz777able]

Great video :) , it helped me set up most of my self build printer, but i dont know how to set the home position and how to tell the printer where to start printing. at the moment when i home the printer the head just goes to the top corner, it does not know where the bed is or where to start the print or even the bed size. any chance you have a video of how to set that up in marlin? thanks for all your videos...

[@yigittarakci]

Thank you so much. It became very usefull video for me. When i finished my clone ultimaker 2 extended's mechanic I'll start working on firmware :)

[@sudhakarnaidu6946]

Hey Tom that was great explanation ,I have used RAMPS1.4 board and in the firmware I defined temp sensor 0 for nozzle and bed sensor for temp sensor bed, nozzle sensor connected T0 on the ramps 1.4 and where should plug bed sensor ,on the ramps1.4 it has T0,T1,T2 PINS please reply

[@hemifivepoint7]

I'm completely new to 3D printing and have a question about the "Motion" section of the config. I understand how to calculate the steps per mm with the Prusa calculator, I just want to know in what order they are respectively in the code. For example, in the config file, you are showing us the values are (80, 80, 4000, 500). What order are these values in? (X, Y, Z, and E) ? I hope the way I asked my question is understood. Thanks.

[@amtpdb1]

Do you have a video on setting up Marlin for a printer not listed and more basic. People who are not trying this for the first time I am sure are clear when you say just change this or add this or go here and get this and add it..... I am new to this and have spent several hours trying different change this and add this or this should be scenarios and have not got it to work yet! Thanks for the videos and I am sure in the future they will make more since.

[@mirage3rd]

I must already have done it on a another video but nevertheless, THANK YOU, or should I say, DANK JE, Thomas. Your help for us newbies is invaluable.

[@andreykuznetsov6226]

Thank you for the video!!! Dear friends! I am building a 3D printer and I need your help and advice. I have 4 stepper motors on the Z axis. Question - How can Extruder 2 driver be used in Marlin as an additional drive for the Z axis (so that there are two drivers on the Z axis that work in parallel (each of which controls two stepper motors) Thanks in advance!!!

[@YahyaChanle]

Could you make another videos for Marlin ... That video so fast and I could not understand, was this work with you?! Because this version of marlin does not work I do not know why it doesn't ?!

[@qbold7093]

Just watched your video since i don't get my probe working properly on my Anet A8. Its a capacitive 18mm probe which seems connected correctly and gives optical feedback once it detects something. However it does not trigger the Z min endstop when homing. At 11:50 in your video you explained the endstop inverting, which was also my first try, but if I change the value of Z_MIN_ENDSTOP and Z_MIN_PROBE ENDSTOP the printer moves the Z axis up instead of down when homing ? And still the probe doesn't trigger the endstop. Any idea what I am doing wrong ?

[@ragabufragsome3426]

i am struggling with my anycubic chiron my bed thermistor suddenly stopped reading the correct value it is showing 19 degrees but when i plug it in the hot end thermal sensor it is showing its at 60 degrees i thing the port is faulty on the mainboard the mainboard has to 0 for hotend to 1 for bed and extra to ports i want to change my bed from to 1 too to 2 is it possible to do through firmware ?

[@squire_icefire]

Great video :) Just one question. In you tutorial you installed the latest RC version. Should we really go for the possibly bug-filled release candidates or is it a better idea to opt for the stable version?

[@nThanksForAllTheFish]

excellent production quality!

[@eserspckoglu9382]

Hello, I can not find an answer wherever you will be in charge, and if I run the 3d printer, the extruder will start to heat itself up and come up to a value of 304 degrees. then when I try to set it myself I get a "maxtemp" error and want to restart the printer. I made the necessary adjustments to the software marlin and code I'm using

[@atifali4703]

In start of video you told " i show you world of c++ configuration files that control every thing about your 3D printer." But you did not tell about lcd and sd card configuration. I am new in this field and did not familiar about c++ so please tell me have you any video about lcd and sd card configuration. Any it very help full. Thanks for sharing

[@timbrown9535]

Thanks for the very informative videos. I followed these directions as best I could but my steppers will not move. When I try to jog them they lock up. I'm searching the firmware line by line but I am stumped.

[@apusarwar2234]

I would like turn on an amplifier for 1s between the movement of xyz and stop. which is connected to aux 1 pin.

[@dunichtich100]

Mein drucker fährt nicht das komplette druckvolumen ab und wenn ich auf den Home X oder Home Y button in Pronterface drücke, dann passiert garnichts, obwohl die Endschalter nicht aktiviert sind, was soll ich tun? :(

[@amirhosseinhosseini7093]

Hi tnx for good Description... a question... I have Rumba+ board and 3 extruder & 1 nozzle and TFT 28 LCD. How add extruder num 3 on my TFT configuration...!? (plz help me I Really needed).

[@jimngugk4741]

Hi Thomas ! compare marlin and Skynet firmware , which one is more user friendly and easy to use ? Thanks :)

[@SplicesAndCelluloid]

Skynet is a fork of marlin. If there is a preconfigured version for your printer, use that.

[@ivanb386]

Hi Thomas, Im replacing a 2560 board that experienced a main power plug short (heated bed not working but the rest seems to kind of work) with a new gt 2560 on a Prusa i3 "CLONE" (pretty crap but works ok...its a printer at my work...I have an Ender 3 which is awesome!! ). Id like to read the current firmware to make note of the settings to upload to the new board. What is the process of getting that information from the original board please??

[@BrettILevine]

I am struggling with adding a "store memory" option to my LCD. I have changed/updated/and flashed the arduino EEPROM code changes and for some reason none of my changes take effect on the LCD. I even un-commented the line you suggested around 13:30 that sometimes causes updating complications. Do you have any ideas what I may be doing wrong? Thank you so much for your help

[@ShawnA560]

Hello My printer auto bed leveling does not seem to be working even though I have added the G92 in the Slicer. Printer performs the auto leveling but I don't see any difference from when I don't use G92. Can I send you my configuration.h so you can tell if there is a problem with it? Thanks

[@donwillson948]

I am having a very odd problem with my Anet A8 in that even though the bed is level and adjusted properly, the first layer of the print is being "printed" 1/8 of an inch off of the bed! My manufacturer has thrown in the towel (they won't/can't help me anymore) so I have no where to turn to for answers. Do you know of a site Where I can ask reliable sources for the answer that might know? I have tried the RepRapWiki and they are stumped as well... Thanks for your help! I watch your channel often and enjoy the information you pass on!

[@bryanlandry3327]

So I updated my firmware as you suggested but I have a problem with Z Axis i have HICTOP 3DP08. the problem is Z axis is not working correctly it turns hard and or won"t turn when I use machine control X and Y axis work great.

[@samblaha342]

I am building a custom delta 3d printer based off of a Kossel xl. I got the end stops figured out (meaning they are triggered when closed). The problem I am having is when anyone of the X,Y endstops get pressed the printer will not move anymore. Do you have any ideas how to fix this?

[@donaldengelmann6906]

I have a question: Why aren't SCARA machines more popular? It seems to me that a printer like the Fabrikator mini for example would get better performance and a larger build space with less material cost with a simple SCARA mechanism.

[@safaenet]

Hi, i use marlin on ramps 1.4. my question is: Is there a way to use marlin in EFF mode but still have heated bed via an external MOSFET ? My goal is to use both D8 and D9 pins for Fans (D10 for Heater) and connect a heated bed to it using an external MOSFET (Don't wanna use RRD fan extender) If So what codes in marlin must be edited to do that ? May i simply remap Heated Bed pin to a free pin ? Which free pin is suitable for Heat Bed ?

[@fntsmn]

Like always really well done video!

[@colinhough5664]

Is there a way to have a part cooling fan and 3 power outputs? at 7:20 he mentions how you can configure the outputs for a extruder, fan, and bed. i want to add in another extruder but none of the board have all 4 things.

[@danoconnell4730]

11:03 What does trigger mean? Does it shut the printer off? I have an Alunar m508 that restarts if I try to preheat the heated bed. I'm trying to figure out if it has something to do with the thermistor being wrong or something else.

[@Thomllama1]

as always, very informative,.. but one thing I noticed, I don't have a "boards.h" file or tab anywhere.... ?

[@DMANDIOGUARDI]

How do you put the Original v1. Anet A8 firmware on the Anet A6 mother board? Everyone seems to be keeping this a secret for some reason. Can any one tell me?

[@keydellfuller5750]

Having lots of trouble heating up my extruder and bed on wanhoa I3. Both presets of (1 and 6) for the thirmester show a bad reading for the extruder. Please help!

Can we get an updated 2017/2018 version of this video in 4k?

[@rent2ownnz]

May 7 2023 - I am really confused. DO I actually need to go and buy an Arduino board to get any of this stuff to work? Will an uno work if that is the case? I am trying to figure out what the hell I am supposed to do to upgrade my ender 3Pro with the 4.2.2 main board. I believe this one has been upgraded to the 32B main CPU..... not sure as there are conflicting stories out there. I thought that if I installed the ARDUINO IDE software is this IDE an emulator?????) , it would allow me to compile a file that I can then simply send it to my ender 3 pro and the system would reboot and update? - TRying to upload the custom Marlin 2.1.2

[@HyenaZin]

is there a way to download example configuration.h file for cartesian printers? im having trouble.

[@n4mwd]

Any advice on how to set up Marlin to run two extruders, a bed and a fan? The standard config allows 3 of 4 of these. I've been searching, but no word on how to control 4 of 4. The MKS boards support this, but I'm actually using a standard RAMPS with an external SSR to drive a 120VAC hotbed. I'm driving the SSR with one of the servo outputs since it only requires a TTL connection. This frees up the regular driver outputs for the extruders and fan. I found in marlin how to move the hot bed connection to the servo GPIO, but I'm still stuck with only 3 of 4 items I need to control.

[@techsavvyhero]

Hi Thomas..If I replace the configuration.h file in the newest Marlin firmware with my Tevo Tarantula i3 printer easy config...will that still keep the firmware new? or is it the weakest link at the older config?

[@starwars65622]

Hi had problems with anet a8 board that came (bundled with auto level) ended up ordering another board this one works but firmware is previous version and doesn't support autolevel need help with good firmware looked into skynet but printer wont connect to pc I need the right driver I guess any advice?

[@ardiwiranata2331]

can you help me ?? i have problem, when i try to homing all axis, always error with code "Error:Printer halted. kill() called", what shpuld i do ?

[@nikoracy]

What if m119 shows all n-stoppers are Open, and yet none of them works . I've checked the pins on the MKS 1.4 board. They seem to be sitting in the right spots (the same as other youtubers). What have I done wrong? Homing any axis crashes the unit into the n-stopper. Pls help

[@ahmadelwaly6514]

sir , i made a prusa i3 steel 3d printer and i use board called lsee v1.0 when i load the firmware marlin on this board the printer do nothing and it doesn't work what should i do and what the changes must be in marlin firmware to be compatible with my board

I've got an issue with my version of the program where the build area is mirrored when I put the part correctly in my slicer of choice it comes out backward on the printer, how do I fix this?

[@schano1992]

There is an option that will tell if the axis direction is inverted by changing the (true) or (false) to the opposite after the the optional axis your changing the direction (it's the option Thomas is showing on 11.30 in the video) I only had to change 2 not all 3 so make sure you check them after changing ;)

[@quad2004]

Hi, I picked up a old reprap i2,, I now have it printing nice, but realized one issue.. I wanted to change a few things and I do not have a backup copy of the Marlin script on the arduino,,,, is there a way i can get the basic info for the printer to show up using some g-code to get the info, so i could set up another arduino with Marlin ??? thinking some ways to save some time then from starting from scratch. ..
