CR Touch With Marlin Firmware

Thank you for making this! I have very limited coding experience and was at a complete loss when setting up my CRTouch. Your video was a lifesaver!!

[@3DPrintscape]

[@CheeseWithMold]

Absolutely fantastic video! For anyone who might find this comment in the future and that it might apply to (small chance, but who knows); I was initially trying to update firmware for a 4.2.2 board on an Ender 3 pro with a BLTouch that was using the Z endstop for 2 pins, and a 3 pin adapter that was given to me by the vendor that sold the BLTouch. To be clear, this was an adapter board that plugged into the LCD screen port on the motherboard, that had 3 extra pins extending off of it where I would plug in the 3 remaining pins of the BLTouch. This would not work, and doesn't seem to have an option in the firmware configuration files to get it to work. In the end, I got a CRTouch that used the normal 5 pin connector on the motherboard, and following this guide to a T worked.

[@3DPrintscape]

Hi. Thanks for sharing your fix and the feedback.

I really appreciate when people type shit out like this. definitely comes in handy when dealing with printer stuff. usually people dont take the time, they just type fire emojis like retards and never update their solutions. thanks!

[@tylerbrauer22]

Thank you so much! I fought with this thing for about 10 hours and the use probe for z homing was not mentioned in 10 different videos I've come across! i learned a lot in that time frame but boy was that frustrating watching my printer crash. Thanks again

Think this is my first ever KZbin comment - I'm about a month into 3D Printing, picked up a CR Touch Yesterday and have been flashing and re-flashing the correct Creality firmware for my board to no avail. I was literally about to take it(CR Touch) off and go back to manual levelling then I followed this video and boom, there's a benchy printing off as we speak. Many thanks for the clear and straightforward instructional video/fix for me Rob!

[@3DPrintscape]

Hi. Thanks for the feedback, im glad i was able to help :).

[@alanrobertson7015]

In addition to your suggestions (thanks again), I also modified the _Bootscreen.h file. The first time I did it was pure vanity; to add my initials to the splash screen. But then I saw it when the printer powered on and saw that it was the fastest way to confirm that the flash took. There is a constant variable called "custom_start_bmp"; where bmp presumably stands for bitmap. If you look at it in the right way, you can see the ender logo comprised of 0s in a see of 1s. That logo appears in the upper right of the VSCode workspace. To make my modifications, I replaced 1's with 0's in the second column from the right (the far right column didn't appear on my printer.) It may be redundant, but I am tempted to add a version number after my initials.

[@3DPrintscape]

Hi. I have made some changes to the _bootscreen.h file before as well. You can actually do a decent bit with it, including adding multiple screens and adjusting how long they stay up for.

[@pabadear]

Thank you so much for this tutorial. I used it on an Ender 3 running a BTT SKR Mini E3 V3 motherboard. I was initially intending on splitting the 5-pin connector on the CR Touch to create a JST 2-pin connector for the Zstopper port but figured there has to be another way - this was it! So, for those looking to see if this works with the same set up, it sure does. I also worked off the Marlin Bugfix 2.1.x file without a problem. When enabling auto bed leveling in Visual Studio Code, be sure to disable mesh bed leveling otherwise you'll get an error when building the firmware at the end. First time attempting anything like this and this tutorial was spot on! Thank you again.

Hi. Thanks for the feedback.

What about the "Z_Min_Probe_Pin"? Does this need to be set?

[@3DPrintscape]

@@motorexp If your building with the right board config as your starting point, you don't need to set this. It will default back to the default pin for that board, which is what you want most of the time.

[@saranisntnice]

After the changing the settings as you told and uploading the firmware all the X, Y and Z axes are only going positive values. Not even able to set negative values from the LCD. Please suggest any changes required to overcome this issue. I have reset the EEPROM after uploading the firmware. Hope you reply soon.

When adding Nozzle to probe offset you mention in the video to measure it. How do you measure it?

[@3DPrintscape]

Hi. For the x and y offsets, you would measure the distance from the nozzle to the probe on each axis. I use a pair of calipers to do that.

[@jrrdw]

To all Windows 11 users, the search is VS works differently then what shows in the video. I could find what I was looking for just couldn't make it take me to it in the code block. Also if looking for things by scrolling everything in the video is approx 150 to 200 lines lower in the code. I was able to work through the differences and get the Marlin firmware installed and now my CR Touch works as intended. Thank you so so so much for sharing this video.

[@3DPrintscape]

Hi. The line numbers will change based on updates to the config examples which is why i didn't say got to specific lines. I didnt notice the search function changing when i went from Windows 10 to 11. Hitting ctrl+f while your courses is in the text field should bring up the search box.

You literally just fixed my newly upgraded Ender 3 Pro! I installed a 4.2.7 board, and my CR touch went bye-bye, along with my -z movement. I was able to figure out which files to use for my board, make changes, and it's WORKING! W00t!

@@3DPrintscape Oi... I spoke too soon? I set the offset values for the Cr touch to my measured values of -43 and -7. However, when I go to auto-level, the CR touch is hanging off the bed on the left, meaning it would completely crush my print surface. Any idea what's going on? This is an upgraded 4.2.7 motherboard, and I used the 4.2.7 config file. Everything I've found SHOULD have fixed this, but it hasn't. Advice?

Thanks bro. I've been actively looking for a step by step to do an edit to the firmware on my ender 5's. I had updated the hot ends about a year ago and have been keeping my eye open for a solution to get those temperatures up a bit. I ended up using a stable version versus the bug fix, but for the most part everything went well. That z offset wizard is the best! I noticed two issues that were solved after doing some research, one was that a manual negative z movement was not possible and that a bed PID tune was not possible. As I said, there were some adjustments that were made to fix these issues. I kind of liked how the CR touch did a 16 point level versus the 9 point level, but with a glass bed, it's really not necessary. Thanks for your help!

Love the video. Also want to make a comment for others - do not unzip the Marlin files to either a network location (i.e. \\some-pc\some_share_directory) directly to the C folder. On the first you'll get errors about remote directories not being supported. On the 2nd, it will attempt to delete some temp files and give you an error due to admin privileges. There are probably ways around these - but just save yourself the headache and use a directory in your c:\users\username folder.

[@vagautohaus4492]

just wnanted to point out though, BLtouch is electromagnet, CRtouch is optical sensor - not sure if that makes a difference to how its set up on configuration.h

oh, another thing, if you check your vid at 10:58 -10:59 youll see a bunch of yellow text regarding DRIVER_TYPE, do we just ignore that?

[@3DPrintscape]

Hi. Thanks for the feedback. Your right, the sensors work differently but the signal sent back to the board is the same, so the config is the same for them. The yellow warning is more of a reminder to check your drivers. The 4.2.2 ships with the normal and silent drivers. The firmware assumes you have the normal drivers but its telling you to verify there.

Great informative video.. i got marlin 2.0.9 running on my ender 3 pro now and got rid of some nasty bugs it came with when i bought it.

Hi, I’ve been very interested in your videos. I wonder if you can help me? I purchased a Creality Ender 2 Pro in 2023. I am trying to install a CR Touch. I read many articles on the subject and don’t want to blow the main board so I began measuring and checking the 5 pin socket on the board. I have Creality 2.4.4s board, looks like it was manufactured in 2022. Anyway, I probed each of the 5 pins in the hope of checking the grounds were correct etc. I read 12v or thereabouts on each pin when using a multimeter. I’m glad I didn’t just plug the CR Touch in. I’m running stock Creality firmware at the moment. So my question is this, if I upgrade and configure Marlin, will it work and change the pin assignments / voltages etc. for the CR Touch or is my CR Touch interface faulty? I’ve built a couple of RepRap printers from scratch in the past but auto levelling is a new topic for me. Do you have a an email ?

[@3DPrintscape]

Hi. I dont think changing the firmware will impact the voltage. The 2.4.4 board is 8 bit so that complicates things as well. You can reach out on discord or email. [e-mail]

[@twc9000]

Great video. Why would someone want to leave the z-axis stop switch in place? What are the advantages and disadvantages?

[@3DPrintscape]

Hi. I know some people still like to home their printer with that, vs the probe. Also, if setup right, its basically an insurance policy incase the probe fails.

[@willn9589]

Hi and thanks for this video it is very well done and one of the few if not only one I have been able to find regarding installing the new cr touch with marlin firmware! I followed both your videos to a "T" have tried everything and cant get the crtouch working yet on my cr10s printer. I have the v2.1 board that does not have the 5 wire connector so I had to wire it several times using z minus and d11 pinouts because wiring diagrams differ so much its been trial and error and is just really pathetic! I have the creality bltouch firmware installed now because there is no hex file available for the cr touch and I cant get my sd card reader on my control box to read the only available .bin file but even if there was i cannot use the creality firmware at the end of the day because of my upgraded heated bed and all metal hot end is not supported in the creality firmware for high temperatures that I need! by putting in the Creality bl touch firmware at least my y axis homing errors finally went away but the cr touch does not work still. It auto homes and then the z axis goes up 3 times before completing auto home sequence and stops at least 50 or more mm above the bed. I cannot adjust the z offset that much!! but am able to go in the negative direction now at least where as it wouldn't using every version marlin firmware there is..I tried them all! I also have upgraded my bed to a 750 watt silicone bed so Creality firmware is not going to work at the end of the day for me but I just wanted to try the crealtiy bl touch firmware to see if the cr touch would at least work and it doesn't even though it did fix my y axis auto home kill errors and allow me to adjust z in the negative direction now. Question: When I use the configurations for the cr10s which one do i use for the 2.1 board? The crealityv1? or the Bigtreetech skr minie3 2.0? I tried the V1 and it does not work at all so thats why I am asking. to be honest I really am wondering if I am ever going to get the cr touch working on my 10s as I have dealt with this mess on my own now for about 2 weeks to no avail and if by starting completely over with another custom marlin firmware build for the cr touch and then adding everything back in that is needed for my upgraded heated bed doesn't work I am going to throw the printer out the window as I am at my wits end here!! Your help would be greatly appreciated! update1: I just used marlin bugfix with V1 config file and edited it per your video and now my printer gets homing error kill every time for y axis again! when i start the z offset wizard the cr touch will home to center of the bed but will not exit the wizard after homing in order to continue setting z offsets. tried setting z offset manually and z will not move in minus direction again! This is definitely an all marlin firmware issue at this point!! Can anyone at all please assist?????

[@3DPrintscape]

Hi. I think the CR10s comes with an 8-bit board, so that will make this upgrade difficult. I dont have that printer, but thats what im seeing based on the research. Can you confirm?

[@3DPrintscape]

Hi. Thanks for the feedback and you're welcome. Im assuming it will be similar to the bltouch but mapping the purpose to the wire color will be important. Im going to play around with that some hopefully this weekend. If I can get it to work, I will make a video on it.

Hi, thank you for this tutorial, you made great job ! Maybe you can help me with my problem, I assume that during printing heating of the bed is turning off in some time, maybe you can help me to turn it off ?

[@3DPrintscape]

Hi. Im not following your question. When you are printing, the bed will continue to heat as needed to stay at the set temp.

[@tchrapko]

Hopefully it's not foolish of me to proceed before I get an answer, but when I went to run the test compile of the Marlin Firmware I had several options including: "STM32F103RE_creality (512k)", a (256k) version, and a couple others ("xfer", "maple"). I'm choosing the STM32F103RE_creality (512k) version. This is on an Ender 3 Pro with the v4.2.2 board. Sound good? Fingers crossed. Thanks!

[@3DPrintscape]

Hi. The short answer is it depends on the chip you have on the 4.2.2 board. I cover it more in this video. kzbin.info/www/bejne/qmW0dmSghdOWo9U

Hello, my set up is, ender 3 pro, glass bed, cr touch. I followed the guide and upgraded to marlin bugfix 2.0. X, . If I go to motion/move axis/move z/ move 0.1, I can't go bellow 0, therefore I can't find the proper z offset. Any ideas?******* I just saw your video on Z-off set wizard, eveything works perfect!!!! Cant wait to apply your next video... YOU r the BEST!!!!

Hi. It sounds like the software endstops are enabled. If you built the firmware you can comment out #define MIN_SOFTWARE_ENDSTOP_Z . If its prebuilt, you can disable it with m211 s0 g-code command.

I'm very new to the 3d printing world and these videos helped me alot. I'm curious though, why couldnt the firmware come precompiled per machine?

[@3DPrintscape]

Hi. Crealty has precompiled firmware, this video is if you want to use Marlin. I also have premade firmware on my site.

[@ronaldfoss]

Thanks again for this awesome video! 1. Where can you switch between 3x3, 4x4, and 5x5 sampling points? Is that in the firmware code or in the menu? 2. Does this bed leveling data get stored so you don't have to do it every print? Thanks!

[@3DPrintscape]

Hi. You would update this value #define GRID_MAX_POINTS_X . Most printers store the setting to the eeprom, but i still run the g29 command at the start of each print to get the latest data.

[@ronaldfoss]

[@scottjackson8931]

Rob, I'm using the Sprite extruder with my CR Touch and I've downloaded on of your preconfigured files from your site. Shouldn't I be able to edit the probe/nozzle offset and then change the bed size (something that needs to be done to make that combo work), copy the files into the Marlin firmware folder then hit the build button?

[@3DPrintscape]

Hi. If you have a build from the same config file it would work but this is a bit older so im guessing you will need to move all the changes over to a fresh copy of the config and binaries.

[@royalegavi7643]

Just would like to say that this looked very daunting at first. I would like to ask that I've gotten E1 heating errors ever since installing the CRtouch, I read from reddit it might be the firmware from creailty is no longer able to support it or something like that.

[@3DPrintscape]

Hi. The e1 error is related to the thermistor, either firmware or hardware related. Check the connections going to it first.

[@vfrpipe]

I have no understanding of anything I did, but I blindly followed this stranger on the internet and my son's 3D printer is almost back from the dead! Blue screen with multiple different firmware versions after installing BLTouch. I no longer blue screen! I still can't home the Z and don't know what is happening there. But man, it's good to have a access to controls at least!

[@3DPrintscape]

Hi. What happens when you try to home? If the z axis doesnt go down connect the z stop back up if you removed it. Creality had a couple versions that needed it removed but most firmware that is prebuilt want it connected.

[@vfrpipe]

@@3DPrintscape After checking the cabling a dozen times, I went with brute force and smashed the connectors with the nippers that come with the machine. It worked. Basically, they were too loose on the pins to make good contact. Up and running at 2am last night! You're video was a godsend, I learned so much. Thank you!

@@3DPrintscape So far it's been great! I have a nagging issue of the table hitting the Y hard stop at the front during leveling, and remaining build time has gone away. But I'll figure it out sooner or later.

Just stumbled across your video. Very straightforward I am looking to update firmware for Ender 3 Max Neo I ended up corrupting the stock firmware after installing sprite pro extruder. I do see the max neo as option. I also am looking for specific offset locations in the code. Any help would be greatly appreciated.

[@3DPrintscape]

Hi. I would start with a printer config example that is close to your printer and has the same board. The main thing here is the board needs to be the same. Then, update the build size and any other settings.

[@cheynespringbett8761]

Great video! With Marlin 2.1, you need to define the probe type for the compile to work, specifying BLTouch, as opposed to manual probe, fixed mount, Z servo probe, etc. I've been having issues with my leveling, with the left side of the bed (the size with the Z-arm) being consistently lower than the other side, producing a slant in my level. Any idea why this might happen?

[@3DPrintscape]

Hi. Make sure you cleared the eeprom after uploading the new firmware. Does your build plate or carriage have any excessive movement?

[@ThaShoeMaker]

Very useful channel! Thanks. I'm just about to embark on the CR Touch install on 3 Pro. I installed the 4.3.7 motherboard and see it has a socket. I'll watch this and hope I do ok. It powered up and says Marlin 1.0.1 - is that the "standard Creality f/w" you mention? I also got the V2 display (not the touch) but was reading a few negative comments about both that and the touch. Have you updated yours?

[@3DPrintscape]

Hi. Do you see any bltouch items in the menu? That will tell you if it grabbed the firmware. I have the crtouch on my v2 with that display and it works fine.

[@werebeertumono]

Hello, I'm having issues with my Creality Sprite extruder. It works correctly with the CRtouch until I send it to home, and that's when it stops working and responding. After conducting more tests, I noticed two peculiarities. It works when I connect it directly to the v4.2.2 board, but when I connect it to the mini board of the extruder, it stops working correctly. By "correctly," I mean it doesn't activate during homing (the nozzle doesn't drop; it stays inside the CRtouch). The second thing I noticed is that this happens after activating a motor. When a motor is activated, a kind of protection is enabled where you can't move them. It's at this moment that the CRtouch stops working when connected to the mini board of the Sprite. When I press "disable steppers" and remove this "protection," the CRtouch starts performing all the actions it didn't respond to before. Update: Yes, indeed, it's the motors. When they receive this voltage, it renders the CR touch unusable. I don't know if you would know how to help me with this?

[@3DPrintscape]

Hi. So its working with the 4.2.2 board but not the skr mini? What mini do you have, what firmware is on it, and are all the end stops connected?

[@L3Thanh]

Hi Rob, Thank you very much for your amazing videos. I've recently bought my first 3D Printer and came across your videos. They're very good with clear examples and details the others don't have. I hope you can clear up my confusion trying to get my bed levelling correct on my Ender 3 Pro with CR Touch - I've followed your tutorials and can't seem to centre the head when Auto Home, it sets X=157, Y117 & Z=10. The issue I have is when I try to run Level Bed, it probes the 9 points, but the prob points furthest to the right have the nozzle off the bed (even though the probe is on the bed). My Nozzle X Y Offset is set to -45,-5,0 as per measurement and other videos/forums. Is this the expected behaviour or can you tell me where I'm going wrong. When I set 'Auto Home' I was hoping it would place X & Y around 120 mark. Thank you

[@L3Thanh]

Actually, ignore me - I'm being a little dense... I realise now that the CR Probe is probing where the Nozzle would be.... D'Oh! 😂

[@3DPrintscape]

Hi. Im glad you were able to figure things out. Is everything working as expected with the crtouch?

[@athmug]

Can you add a part about when the leveling of the bed occurs off the bed? Like the first point after the center is completely off the side of the bed. Thanks!

[@3DPrintscape]

Hi. Try to clear your eeprom, that fixes that issue most of the time. If that doesnt work, you may need to adjust the X_MIN_POS and Y_MIN_POS in the firmware.
