Replacing your fans on the Ender 3 will help lower the noise and possibly push more air. Take note of the voltages of the fans below before purchasing new fans. Test center of bed to confirm a completely flat bed. Raise or lower other 4 corners and re-level if necessary. Note: Make sure there is no extra pressure on the bed. Any pressure on the bed will cause incorrect leveling due to the compression of the springs on the leveling screws.

How-To Guide.PID tuning refers to the parameters adjustment of a proportional-integral-derivative control algorithm used in most repraps for hot ends and heated beds. If the temperature ramps up quickly and slows as it approaches the target temperature, or if it swings by a few degrees either side of the target temperature, then the values are incorrect.
This will heat the first nozzle E0and cycle around the target temperature 8 times C8 at the given temperature S and return values for P I and D. In the case of multiple extruders E0, E1, E2 these PID values are shared between the extruders, although the extruders may be controlled separately. If it is not enabled, save these settings in Configuration. If you have access to a PID controller unit and a compatible thermal probe that fits down into your hotend, you can use them to tune your PID and calibrate your thermistor.
Connection of the output of the PID to your heater varies depending on your electronics. After the PID is connected you can use it to measure the nozzle temperature and correlate it with the thermistor readings and resistances.
Converting these to Marlin PID values:. Differences between the results can be caused by physical differences in the systems, e. The kP,Ki,Kd lists the converted parameters.Creality Ender 3 Pro - 3D Printer - Upgrades & Fixes

It also didn't look like there was any easy way to move the bed either. Yes, this is the "intended" behavior, as the home in relation to the physical limit position is not placed correctly about 7. In the firmware, an offset is defined from the build plate origin to the endstop locations. This is normal, nothing to worry about. When you hook up your printer to your computer over USB, and install a program that can interface with the printer e.
You will then see the head move to the origin, which should normally be the left front corner. If it did start on the build plate you could crash the nozzle when the bed is not levelled. Note the level varies with temperature and build plate type. Having just had the innaccurate z-end stop switch cause a deep gouge across my stock build plate, I strongly recommend getting an ABL auto bed leveller. Sign up to join this community.

Active Oldest Votes. Trish Trish If so then why should it be "corrected"? From what I've read, every Ender 3 including mine homes off the bed, and some people say how to "fix" it while others say it is supposed to be that way so presumably we should leave it that wayThe default heat manager for the i3 printer is using the DeadTime method which usually works pretty well.
The heat manager can also be changed to use PID which can yield better results after running the PID Tuning command for a set temperature. PID is a control loop feedback mechanism with many uses. A general description of PID is beyond the scope of this article. Tune the PID control system to the temperature you most frequently use. If your printing temperature varies greatly for example, you print low temperature PLA as well as higher temperature ABS or PETGyou may find that tuning somewhere in the middle will work but you will likely have to re-run the tune for the new temperature each time you make a drastic change.
Changing and tuning the PID control is a means of addressing unstable temperatures. If you do not have temperature fluctuations, then there is no need to do this. Description The default heat manager for the i3 printer is using the DeadTime method which usually works pretty well. It will show the progress on the screen and when it has completed you are set to go.

This consists of the Temperature that you want to reach print at and the number of cycles of tuning to run. Go to the Manual Control tab.
Note: Some older versions of the firmware take a P instead of C for the number of cycles. Once you hit send, the auto tune function will take about 15 minutes to complete.
You will see the following information in your log appear multiple times with different numeric values Note: Your values will be different! You will see one last set of numbers. The values you are looking for are Kp, Ki, and Kd.
We'll assume you're ok with this, but you can opt-out if you wish. Accept Read More.Not happy with how your 3D printer keeps its temperatures? So, temperature control is one of the most crucial features of our 3D printers -- while the earlier printers simply controlled the temperatures of the hotend and later on, the heated bed, by simply turning the heaters on when the temperature was below the setpoint and off when it was above, todays firmwares use a much more elegant way of managing heating.
Simply speaking, they determine how much power to send to the heaters by looking at how large the difference between the actual temperature and the setpoint is, how long the actual temperature has been off from from the setpoint and how quickly the temperature is changing at the moment.
The other option is C as in Cesar, which tells autotune to run the tuning process a couple times in a row and improve the results with each pass. The hotend will heat up and then cool and heat again around the target temperature for ten times.
It will report back to you each time it has finished a pass and give you a set of PID tunings. You can temporarily set them until the next time you reset the printer by using M with P, I and D and each of the calculated tuning values as arguments. You can then go and try these shiny new PID tuning on a print -- Marlin will use them until the next time you disconnect from your printer.
Now, that was for tuning a hotend. If you want to use PID for your heated bed, there is one more option you need to add to the M command, and that is E for extruder. The heated bed is extruder negative one, the first hotend is zero, the second hotend is one and so on. By the way, if you have more than one hotend, Marlin will use the same PID tunings for all hotends, no matter which one you used for autotune. To make the settings permanent, you can either send a simple M, which will make Marlin automatically load up the values you just set with M and M each time you power up your printer.

I currently at 8mm x 20mm springs and have found they are more consistent that the stock springs provided by creality. A month or so ago, I bought two Creality Ender 3 Printers. Overall, I still love em.
They have been printing non-stop and I would still highly recommend them to anyone just starting out or looking for a entry-to-commercial duty FDM printer. They are beasts and both are going right now. Best consistent deal I have found. On the left one, the base is not level even though I loosened it all up and it is just a tad more finicky.
Initially, they would both print and print again without adjustment.
But after a week or so, The Bad Ender, would require that I manually level the bed, on the fly, at the start of each print. This week, I decided to solve that and this post will document that so that other benefit. It never hurts to use a little Loctite Blue — medium strength — threadlocker! Here is how I lay out my clips so the print head will not hit them.
What I learned is the bed would not stay stable between prints no matter how gently I removed the build plate. If you want an assortment of Metric screws and nuts use this link. Tighten them all the way down. Snug them up. Replace the bed with the sprints between the base and the nuts. Another view. And another…. Put the leveling wheels back on. All the way around and tighten them up. Take a look at the nozzle and make sure the bed is below the nozzle before trying to level.
A little more than that…. Just about right. Level all four screws until the bed is level, this will keep you from damaging the print surface.The Ender 3 Pro comes partially assembled. The base of the printer containing the print bed and the Y axis back and forth control as well as most of the wiring are already assembled before leaving the factory. To finish putting the printer together will require connecting the remaining parts to the base using less than 2 dozen bolts, and then plugging up a few wires to the various motors.
The instructions that come with the printer do not have words, just pictures. Fortunately several decades of assembling Lego kits served me well in figuring out what needed to be done.
Once you unpack everything you will need to attach the uprights to the base. Then you connect the gantry arm to the uprights. The gantry will control the X left and right and Z up and down axis movement. Once that is completed, you only have a few more bolts to tighten up and a couple of wires to plug in and your printer is ready to start printing.
Sorry that I did not take pictures of the assembly process, but the process is straight forward and the images in the instruction manual are easy to understand. I will be linking to a bunch of different 3D print files that I found on Thingiverse.
I do not have affiliation with any of these authors except myself lolI am simply providing access to the files I used to set up my printer. If you want to use different test prints feel free to look around, there are lots of options. Did you use this instructable in your classroom?
Extruder PID Tuning
Add a Teacher Note to share how you incorporated it into your lesson. Once the printer is assembled the next vital step is to make sure the bed is level in relation to the print head. There are 4 knobs, one on each corner of the bed, that will raise and lower that corner. Turning the knob to the left raises the bed towards the print nozzle, turning it to the right lowers the bed. To properly space your bed away from your nozzle, you want them close enough together that when you have a single sheet of paper between the bed and nozzle there should be a slight amount of friction when you try to move the paper.
It is a simple test that prints 3 passes around the perimeter of the bed and then it prints a filled circle at each of the corners as well as the center of the bed. Push the button on the printer after testing each corner the printer says something like "waiting for user" to go on to the next corner. After stopping at each corner twice, it will print several skirts around the bed you can continue to adjust height as needed as the skirts printthen a disc in each corner and a disc in the middle to check adhesion.
There are literally thousands of videos available on youtube regarding 3D printing.
HOW TO: PID Auto-Tuning for Ender 3 and Other 3D Printers
I watched a lot of different videos to learn about the printer that I got and how to set it up to get the best results. One of the better youtube channels that I found was Teaching Tech. Michael does a great job of clearly explaining each test and how making changes to the printer will affect your print results.
The arms print at increasing angles of overhang from 10 to 80 degrees. If you look closely at the picture of the backside of the arm you will see that it is not until after 60 degrees that the print starts to get ripply yep. This will make sure that your extrusion temperature is set correctly so that you are able to bridge sort distances without support without sagging or delamination of the layers.
Stringing happens when there is too much pressure in extruder and melted plastic leaks out during movement in free space. There are 3 majors values, which you are going to adjust to remove stringing : retraction, temperature and travel speed.
This tests the ability to make crisp clean corners and tapers. This tests the ability to make fine lines and grooves. Tests the accuracy of the scale of the circles outer and inner diameters of each circle are listed.
