As a first time printer, I just had to add a comment here about your videos. They have been a Godsend to me. You are very complete, well spoken, and the level of detail you provide is just simply amazing. I thank you VERY much for your efforts! Because of you I'm guarantee that 1000's of people are printing suggestively because of your efforts. On behalf of all of them, THANK YOU!

Thanks so much for this! All of us in the Ender 5 community appreciate it!

Thank you Michael, I've had the stuff to do this for months but been too scared to do it, It all worked fine and is printing away as normal again. You're an awesome teacher, keep up the great work.

I got my first printer a month ago and I am already wanting to do upgrades. I was kinda intimidated with this kit but after watching this video I am confident in my ability to get it done. Thanks for the great instructions!

BLTouch is such a nice addition. I used to calibrate my printes manually for years, but with nowadays tech you can forget about calibrating a 3D printer. Very nice video! I actually like more the repeatability of the inductive sensors instead, but that's just a taste choice. :) I hope you all have a great day!

It's good to see TH3D is finally supporting the BL Touch

Hey Michael, another great video. Thats the same technique I use to thread the wires through the sleaving. It took a while to work it out, but it really does make it so easy. I also wrap the ends in insulating tape or heat-shrink to stop them fraying. I no longer strap the wires to the PTFE, this is because the wires add weight to the PTFE and cause it to bend, this creates tighter radii which causes more friction resistance on the filament while extruding. To support the wires I thread a piece of 3mm nylon filament through the sleaving with the wires and anchor it at both ends, again, this helps to reduce the any bend radii on the wires, therefore extending their life. Hope that all makes sense :-)

thanks man. got this installed and working. couldn't have done it without your video.

Thank you for the tutorial. I know it takes a lot of time and energy to make these. Really helped me get my setup working well. Cheers.

9:05 is where ive been stuck at for weeks! thank you for sharing in detail!

Michael, if you simply compress the entire cable protector, it will expand in size, and become about 15-20cm long, but 2-3cm in diameter. That makes it very simple to feed the wires through.

I know this video is old but it was super helpful.

Fantastic video, thank you for posting!

Yes, the machine has the v1.1.5 motherboard. I made my own extension lead to the BLtouch from a bit of ribbon cable, 1m isn't quite long enough. I used the TH3D firmware as, when I tried to follow the vanilla Marlin instructions I ended up with an executable which was too big for the processor. Using the TH3D (version R2 config.h version 010109) worked ok and the v1.1.5 board had a pre-installed bootloader which kept things simple. Thanks again for the instructions. David

Thankyou, i have a blue screen on my E5p and i think the pinout may be wrong, cant wait to try this.

Thanks for the video. Just a question, can you upgrade the main board to an MKS Gen L as per your MKS Gen L guide video?

thanks for the guide, what type of extension should be used with BLtouch? AWG 26?

I have a cr-10s and that printer has 2 cables running to the lcd. To witch one do I have to plug the pin 27 board? Love your vids by the way especially the ant vid.

Hey been watching a few of ur videos but do you have a tutorial doing this for the 2.0 upgrade step by step I tried to follow this but for some reason I’m have sanguino errors when I try to compile

Quick question, in your configuration files which you offer, the modifications from this video aren't already done (bltouch isn't enabled, neither are the offsets correctly configured). Is this per design?

As far as the backplate.. There is a 4 roller plate on amazon that connects the drive belt on the other side, leaving that area free on the ender 5.

Thanks Michael. I'm just curious if anyone has checked the true Z-Axis setting repeatability of the BL Touch. Using an accurate dial indicator. Particularly over time and with many iterations.

I wish Creality would make an update kit with touchscreen and bigger mainboard that you could buy, because that size limitation looks like a real PITA.

Any chance of an Ender 3 klipper install guide?

Nice informative vid. Cheers Michael. I noticed that the TH3D BLT presets are very slow and on the conservative side, probing took 2min. Too long for me, so I also made a point of speeding mine up.,and safely got it down to 40sec.

I have an Ender 3. I just tried to update the firmware to run the BLTOUCH and I can't seem to get the firmware to update to the latest TH3D in order to run the new sensor.

Is there any difference in installing bltouch v2.0, 3.0, and 3.1?

I also posted this comment on your Ender 5 Marlin video. It would have been helpful information when I began this process and thought maybe it would help someone else or possibly me in the future :) I found out how to flash using the original ISPUSB that came with the printer. You just have to export Marlin from Arduino, which creates a hex file (in the Arduino directory, bootloader included) that then is able to be written through the progisp program from Creality. I had a few hurdles, after doing the modifications in this video, my compile was at 98% and though the compile completed the flash ended up giving me the blank bluescreen on boot error. Looking through the compile I noticed two errors, one with ultralcd.cpp the other with temperature.cpp which lead me on a wild goose chase, After realizing these were both temp files I figured they weren't an issue and redid the whole firmware watching your videos again from start to finish. I achieved the 98% before commenting out the ARC feature in your Bltouch video and thought it was ok. This time after writing again and failing again.I decided to comment out the ARC this brought me down to 96% and finally a fully functional printer. Next issue I had doing a test print was that my prints were getting smashed as though it was not raising up the Z axis enough, I discovered that the Ender 5 PRO has the lead rod upgrade. Your configuration files are for the 400 lead rod I finally found that the code I needed to edit was here... #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 800, 93 } Now everything is wonderful! Thank you for your help and the education!

when you set the x and y axis, is the meaning that the nozzle is in the midle of the bed or the BL? on mine ender 5 The BLtouch is on the middle

nozzle. the software should handle the offset.

Hi, you say here we are in Marlin but don't say how to get in there after the bootloader.

On a different board (SKR Mini E3) I was able to install the firmware by putting 'firmware.bin' on an SD card, loading the card in the Ender 5, and turning the power on. Does that work on Creality boards after the bootloader has been burned?

Hi. I bought myself the new (silent) 4.2.7 Creality3D Board (also known as 1.1.4): Is it the same procedure to within updating to BL Touch like the one in your Vid (1.1.4 i guess)? Thanks in advance :)

Hoping someone can help me. Got it installed got firmware loaded everything seems to work but when I do a leveling print no matter what I do the left side of the bed is too low. I have leveled the bed to get it into the ballpark but regardless of my settings the left is too low

Am I the only one having issues with this marlin setup? It’s not doing the abl (yes g29 has been added to the slicer start code), and it appears to be trying to print only on the front half of the bed. Had the same ABL issue with the TH3D firmware (just probes the center then starts the test print), but that printed using the entire bed.

I'm having a weird issue. I have a mostly stock ender5. I added bootloader, marlin 1.9 with the proper config files you supplied and a bltouch. Everything worked great for a few days. I had a long print finish, and now my Z homeing direction is backwards. When manually controlling the directions or correct. Any ideas what caused this and how to fix? EDIT: I figure out it is the probe is sticking

I did this right from pretty much the very first shot! Except, there was one thing that wasn't mentioned. The newer Ender 5 (perhaps even after your video was made) have a new z axis screw that is 800 steps/mm. The example cfg files for the Ender 5 have this set at the old configuration of 400 steps/mm. This leaves me with a question I'm having a hard time finding the answer to. How do I upload the changes I've made to the cfg file to my board, now, with the boot loader? I tried to just plug in and upload, but, was not able.

My BL-Touch came with a 5-pin cable, and I added a 32bit board, which has the socket already...

8:38 In Marlin 2.0.7 it is NOZZLE_TO_PROBE_OFFSET

Okay so I'm new to this, and I don't know what is bltouch and what is it for, can anyone explain it to me ?

I'm not sure this is an issue but my config.h is missing a couple lines. I flashed 1.1.9 as per your previous video and it's been working great but auto bed leveling sounded good. * The BLTouch probe uses a Hall effect sensor and emulates a servo. */ //#define BLTOUCH /** * Enable one or... I'm missing the #if ENABLED(BLTOUCH) ..... endif Any thoughts anyone?

Hi there, Help me pls : my ender 5 with bltouch original and firware from creality make two pb : - levelling end outside the bed for the 3 left side checking (around 3 cm out if the bed...) - last but not least, my extruder go the right at the end if levelling and go crash against the sensor of the axis and thé printer stops after... I really need tour Help because my Friends from the hospital want me to print lots of "door grabers without contact" to prevent from covid... Peter (from France)

why doesn't anyone just use the default mount for the BLTouch. I cant seem to find the default nozzle to probe values.

So if I understand correctly with the latest TH3D unified version all that needs to be changed to get BLTOUCH support is to update the configuration.h file, modify the printer section for the model being used to enable the custom_probe, edit the BLTOUCH section to enable it and pin 27 support and adjust the probe offset location? So much easier then in the past. I'm assuming this will work for the Ender 3 as well, just uncomment the Ender 3 sections.

Looks like this solution doesn't work anymore. Creality keeps updating the firmware so it gets larger and larger. Some of the recommended lines to comment out were already commented out. The few things I could comment out I was still 8000 bytes over. I don't know what else I could remove without making the whole thing not work. Also the pin 27 breakout board I received didn't allow my LCD to work through it. Tempted to look at just buying the TH3D EZ board with an EZABL sensor now.

this video is really great for setting it all, but how do you USE the bed leveling? I've enabled the lcd_bed_leveling but when I press "Prepare>Bed Leveling>Level Bed" it completes the sequence and that's it. No info on what parts of the bed were too high/low. Is that how it's supposed to run? how to I level the bed??

@SpoonOfDoom

3 жыл бұрын

If the bed isn't perfectly level, the printer will now be able to compensate for it because it knows the precise position of the bed. (Of course it's still a good idea to set the bed as well as you can, so the printer doesn't need to move in the Z direction more than it has to). I think where this really comes into play is compensation for a warped bed - you can't straighten that out just by adjusting the corners. At least that's my understanding of this whole thing.

Anyone know how to get this running with the new V3 of BLtouch? It seems that version isn't recognizing a probe impact with Marlin or TH3D.
