what firmware to flash to get Bl touch working?

@immaculato I am sorry the R&D does not have the updated firmware for 10 mini, as far as I know. One alternative way is that you could try an ender 3 BL touch version for your printer. As long as the mainboard version is the same and the main parts are similar( bed size, screen)

@degezx

Then I should probably give it a try 🙂 

Did you use XLoader as recommended on the website you shared or did you stick to the BLTouch instructions and used progisp.exe with LowValue=D6, HighValue=DC and ExtValue=FD ?

I have included a picture of my BLTouch, where the version SMART 3.1 is indicated, is it the same on yours? Maybe you could have a look at yours, after you finished your print.

Really appreciate your help, I am just a bit worried to destroy my Cr-10 haha.

Good luck with your print!

@kingblackfox thanks, print came out really good haha.

i used the Stick that came with my BLtouch kit, useed progisp with the same values you described, i too have the BLtouch SMART v3.1 so you should be fine 🙂 

the steps in this tutorial are the same that i did, minus the ender 3 firmware of course

little disclaimer tho: the firmware that i used for my cr10 v1 doesnt allow negative values on the "move axis" part, so to set the offset you'll have to do some tries, nothing too hard tho, you can ask me anything about the entire process if you get stuck

@immaculato you can probably find some here

on the "hex files" folder

@degezx

You are my todays hero! 😉 Works pretty fine, the Z-Probe Offset is indeed a bit of a try-and-error approach. 

For me, a Z-Probe Offset of -4.05 seems so work good, if someone needs an orientation.

@degezx Sometimes the printer starts with this firmware with a bluescreen and I had to restart serveral times, I think it has something to do, whether a SD-card is inserted or not? Do you also have such a problem? I used the "Cr10_bltouch.sanguino.hex" file, not the "CR10_bltouch_.with_bootloader.sanguino.hex".

To auto-level after bed-heating I am using the following starting script for cura, works for me, but I am no expert;) Maybe helpful for someone.

@kingblackfox

yes, i too have that issue when powering the printer on cant quite figure it out, sometimes works fine with the sd inserted, sometimes not, i know that if the cooling fan starts spinning its gonna be fine, but that approach its not ideal, im currently working on making my own firmware, if my printer doesnt blow up i can share it once its done

i too have an auotbed script but its for simplify3d

@kingblackfox hey partner, updates, you might wanna try this one

GITHUB.COM "https://github.com/InsanityAutomation/Marlin/blob/CrealityDwin_2.0/Hex+Files/CR10_BLT_SD_DW7.hex.gz"

the one i recommended before had a lot issues connecting via USB but this one is A LOT better, lets you play with the steps and everything, only issue i've encountered this far is that it wont let you bed level manually you either have to G29 on the code or send the code manually, to be honest i never used the level bed option from the menu haha, always used it direclty from the slicer code. also the z offset isnt a pain in the ass in this one :^)

you can either download it from the github link or directly on the attached files

@degezx

Thank you for your efforts! I will try it out as soon as I have some free time again and will give you feedback here. I also only use bedleveling via G29, so that wouldn't be a problem for me.
Your Github link seems to lead to a 404 for me.

@eli-liu did you get it fixed. if so can you provide a link to the right firmware.
