Download preconfigured configuration. Copy this file and paste it in the main folder. If you are going to use two extruders you will have to change the line to. I think it is not worth the time setting all up. Just get a new display for a couple of bucks that is compatible to the Ramps, like this or Then we will have to configure marlin to use the display we have.

For the full graphics display use the following one:. You will also need to install the u8glib library. The Anet A8 used a baudrate of This is already set up in the example configuration under:. Under the following line you can set up how many extruders you are going to use. If you have the standard A8 leave the number on 1. If you are using the normal thermistors you can leave the settings as is.

However if you changed the thermistors for example to the NTC use the thermistor 1. For the hotend change the following line:. A safety feature for the thermistors are the mintemp.

This is for example necessary if the thermistors are not connected or broken. So that the printer will not heat up till it begins to burn.

Marlin RC8 AUTO BED LEVELING BILINEAR

Another safety feature ist the maxtemp. For the hotend the temperature is limited due to the PTFE inliner, which decomposes above these temperatures and produces toxic fumes. For the heatbed it is a safety feature against burning.Additionally, this process often has to be repeated after several prints due to the possibility of the bed going out of alignment after several hours of use.

In some cases, it can even lead to a clogged extruder or scratch marks on the build surface if the nozzle is far too close to the bed. Luckily, many new 3D printers include an automatic bed leveling feature that makes it easy to ensure you are printing on a level bed every time. This article will explain why the auto bed leveling feature is important and how to use it in Simplify3D. If your printer supports automatic bed leveling, this usually means that it includes some type or proximity sensor or switch near the tip of the extruder.

When you initiate the bed leveling process, this sensor will probe several locations on the build platform to calculate the distance between the nozzle and the bed at each point. So even if your build platform is slightly unleveled, the firmware will make small adjustments to the Z-axis while you print to ensure the nozzle is always the perfect distance away from the print bed.

If the printer you purchased already includes auto bed leveling directly from the manufacturer, then the Simplify3D profile for your printer should already be setup to use auto-leveling at the beginning of each print. Run a small test print and watch to see if your nozzle starts probing several different locations on the bed before the print begins.

If you want to know more about how this process works, or you need to enable this functionality for another 3D printer, keep reading and we will explain all the details.

To enable auto bed leveling, we will need to edit the profile for your 3D printer. This script defines the actions that your 3D printer will perform at the beginning of each print. We are going to add the G29 command to this script, which tells the printer to perform the auto-leveling process. However, keep in mind that the printer needs to perform is normal homing operation first before it begins the auto-leveling process.

Make sure that you place the G29 command after the last G28 homing command in your starting script. The screenshot below shows an example profile that is properly setup for for automatic bed leveling. Please note that starting scripts may vary from one printer to another. Just make sure that the G29 command comes after the very last G28 command in the script.

After you have made these changes, go ahead and save your new printer settings. To test if the changes were successful, start a new print on your 3D printer and watch to make sure that the automatic bed leveling process executes at the start of the print.Bilinear bed leveling and associated gcodes and procedure Posted by gavatron Hey guys, I made the move from rc6 to rc8 and have configured to use the bilinear bed leveling.

By issuing a G29 my machine begins probing and goes through its probing routine. I see the resulting mesh in the terminal, all good. Now if I issue G29 S1 to save the mesh it just probes again but doesn't seem to echo a save command, it just echos G I can't seem to get the mesh to apply for a print or save and I believe I may have missed a step or I'm issuing contradicting gcodes.

I have a feeling if I issue a G28 after a G29 it will wipe the mesh, but again documentation on this new feature is elusive and minimal.

Could someone point me in the right direction? Cheers Gav Reply Quote. Positive away from bed, negative closer to bed. Reply Quote. Ahhhh righto no worries, that makes sense.

So just to clarify M will save the mesh like before using manual mesh leveling as well as M S1 to activate the mesh? Thanks for the help mate Gav Reply Quote. It depends which system you are talking about. M used to save the mesh in the UBL system, but that was problematic for a number of reasons. M no longer saves the mesh in UBL. It is my belief it will save the mesh when using Bi-Linear leveling in RC You can verify that pretty quickly. Yep referring to the bilinear in rc8 Reply Quote.

UBLis a bilinear with fade height toobut very complete to make precision meshbut in theoryeverybody have a ' correct ' bed and will not need to probe some other points after the automesh generated.

I recommend you use it to report all informations to help the developers to make it more simple. You can save your meshand use it on each print No need to enter dimensions values in firmwaretotal area is used automaticly You can make a mesh without probe and with an endstop ' manually meshing ' You can make it with hot bed and nozzle at different temps You can adjustadd a new probed point if needed outside of the predefined grid You can make a test print to validate if you are not sure of your mesh.

Becauseall devellopers have decided to make war to the first layer. It's a good idea becauseit's really possible. And it's made nowUBL will scan all the surface ' 10x10 points by defaut'will make a smooth mesh that can be very precise with the interpolation between probed points. If we set a good mesh 'UBL is made for this 'we can have the first layer perfect like the second layer lol!!

No you're not dreamingplay with UBL and you will have this results. Thks to Roxy-3D. For informationthe only material that can help you to have a perfect bed immediatlyis the vitroceram glass or borosilicate3mm glass can hold 2kg of plastic without bendingif you can buy 4mm or 5mm glassyou will have a buildplate impossible to bend with the heat or the weight of the object My buildplate is x and 3mm and with thisi don't need autolevelthe bed is so perfecti just use the probejust for swapping the nozzle and adjust offset by firmware.

Sothe first jobis to make 'mechanicaly' an amazing buildplateand if you have thisyou can use a probe ' bltouch' or other to probe the zerobecause when you change the nozzleyou don't have to touch your bed screwbut just to find the offset by softwareno mechanical modifications The probing with sensor offer to never touch the bed screwsbutsometimesyou can verify it lol To make a perfect bed on another already installedcut a borosilicate glass and fix itto fix it you can glue it with silicone '5mm of perimeter glued is enough and very solid 'and place under one or two coats of aluminim paper to equal to the height of the silicone of the edgethis solution worksthe bed can be unmounted and back to origin mounting and the heat conduction is good.

Before -Mesh Inset must be goodif notthe probe can not go everywhereif you choose a 3x3 grid ' in firmware'your mesh must probe 9 times if notset better the MESH INSETor use the manual mode -Try to inform the firmware of the area the probe can reachif notyou will have 'unprobed zone ' and you willl have to make it manually and it takes time for nothing.

Print Behavior With UBL precisionyour first layer will be perfect mathematicly and it's a problem for users that never have this precise settings. Because the first layer is not compressed and the risk of bad printing is possiblethenask to your slicerto reduce a little the first layer height and SLOW the speedthe extrusion will have no pressure on the build plate andthe fixation of the melt plastic can be corrupted.

If you have winnowyou can tweak value and make your own adventureyou know all is needed to go deep in this abyss.

No need of G29before printingonce activatedyou can print directly. This tool 'if defined in Firmware ' will heat bed and nozzle as specify and print some linesyou will now see where you need to add some probing points to perfect you mesh but always with the minimum points as possible ' of course'.

The printer should be able to successfully print a small object at the center of the bed. It is very important to verify the configuration.

My CRS came with marlin 1. The latest version of Marlin is 1. Is there any substantial benefit to updating Marlin to this version on the printer? There are a ton of bug updates and changes between 1.

Personally I'm running 1. Really easy to add a BLTouch for automatic levelling too. To help I've cut down the change log on the marlin website and pasted below I cut out language features and some other development related stuff :.

Yeah, how does that work anyway? So if I don't have that, does the 1. It is a manual process that measures nine points on your bed and works very well. The only tool required is a piece of paper or a feeler gauge. MBL uses the mesh to compensate for variations in height across the bed. Not if you're just keeping the printer stock.

If you ever decide to start upgrading components or adding features then yes, I would. If the stock firmware doesn't store e steps then it's not a full Marlin load.

You will end up with a few rows and columns in the mesh map that are not automatically populated with the Z-Probe. G29 P3 T maybe twice depending on your mesh resolution should fill in the unprobed locations. Reply Quote. Along the lines of ubl I have been reading whatever documentation and old threads I can dig up and due to the age of what I found I am still a bit confused on ubl.

I am currently using the latest skynet3d firmware which is based on marlin for my anet a8 printers. Skynet3d has the option to use ubl but it was easier and faster for me to setup bilinear leveling.

I have tested my inductive probe and its deviation is along the lines of 0. The bilinear mesh data shows this as well with point 2,2 having a higher positive number than the other points after probing a 3x3 grid.

I tried a 9x9 grid at one point. What I noticed is that the high side of the bed sees the closest point of the nozzle and the low side sees the farthest point. I thought auto leveling was supposed to adjust z up or down to keep the gap the same but it is not happening in this case. My z offset has been set correctly My mesh data is being activated in gcode prior to the print start with M S1. I was looking at ubl to test but with all the information I have seen about manually editing the mesh it seems counter intuitive to the name "auto level".

marlin ubl vs bilinear

I like the notion of using g26 to print a test pattern to verify the mesh level data but this option is not available for bilinear leveling. So I am wondering, what is there about ubl that would make it more desireable over bilinear and how can it be done as automagically as possible?

Thanks for any information. Edited 1 time s. Quote So I am wondering, what is there about ubl that would make it more desireable over bilinear and how can it be done as automagically as possible? Thanks roxy. I have no problems overall using bilinear. This allowed me to see how the gap looks as the nozzle tracks along the bed.There are 5 main types of auto bed leveling currently available at the time of writing this article:.

In order to utilize UBL, you will first need to enable it in your firmware and re-flash your machine. Using Arduino IDE, go to the "configuration. To make things simple we will show you the typical start code we put in our slicer for UBL.

Then we will go through line-by-line so you can understand what each function does and decide if you need to make any changes for your own setup.

This function ensures the bed is up to temperature before taking any probing points. This is critical to getting accurate readings as the bed will change shape when heated.

Homes the machine so it knows the location of XYZ "zero. Runs the automatic probing routine for UBL. Extrapolates the leveling topology to areas of the bed the probe could not reach. This lets the software make an educated guess on bed topology in the areas it was unable to probe. For example, the probe may have only been able to probe the area in green see below due to machine limitations and probe position.

G29 P3 will use the surrounding in green to fill in the missing mesh data for the areas in red. Sets fade height to 10mm. The first 10mm of the print will have a variable Z position during the print. This means the nozzle will follow the ups and downs of the build plate on the first layer, however, over the next 10mm this effect will taper off.

This allows the rest of the print to have a constant Z which will likely lead to cleaner, more accurate prints. Note: if your bed is not leveled properly, this can result in finished parts that are out of square as shown below. This is why it is vital you still level your bed even with ABL capability. Saves the bed topology results into slot one.

Loads mesh 1 for the current print job. If you have multiple meshes saved in different slots you can also call a different number mesh here. Simply replace the L1 with the appropriate L number.

If you do not save, all data will be lost after powering down the machine. There are more functions that can be used with UBL, however, these are more than enough to get you up and running.

It offers many tools like the ability to save multiple meshes and manual editing of probe points. In addition, you can recall an existing mesh using G29 L and then run G29 J afterward which will probe 3 points to tilt the existing mesh to match your build surface in case it has changed since running previously.

Getting a grasp on all of the functions can be intimidating at first but once you get them down it will ensure you get a perfect first layer every time!
