BLtouch frustrations, trying to get back to original firmware

Hello everyone, I'm very new to 3d printing, I started with trying to print PPE shields and decided I wanted to try printing with a BLtouch. Turns out I got a knockoff from ebay that isn't playing nice, I'm trying to figure out how to remove it and go back to default how the printer was shipped. I'm really at a loss on how to set the firmware back. I have read a lot of posts on trying to work through the issues but I think it is just a junk knockoff that is the problem.

​

When i remove the bltouch and put the z sensor back in the LCD beeps at me, i guess that is how the bltouch is controlled through an audio connection.

​

I've tried to set the fuses back to default without the BLtouch installed but just get the LCD stuck o the creality logo.

​

I'm afraid to brick the printer but feel i might be close to it.

​

I have seen articles on how to get to marlin but i don't have the background or arduino to do so.

​

Any thoughts on how to get back to default and the BLtouch out of the mix.

​

Thank you all

Correct. Servo pin is repurposed from beeper. You cannot run a bltouch enabled firmware without a bltouch.

I've tried to set the fuses back to default

What fuses?

How did you flash in the first place? Have a bootloader installed or used an ISP?

You should be able to go back to factory firmware

That worked, Thank you. I know it was a simple link to share but I would have spent hours trying to figure it out. I really appreciate it

I used an ISP

​

one of the bl touch videos referred to the low/high/ext values as fuses, I'm way too new at this, i know that is probably the wrong term

Did you install a bootloader and replace the firmware when installing the touch? A touch won’t work on default firmware, you have to flash the mainboard.

Thanks, I was able to get things working again once I was able to find the right firmware with out the BL touch in it

Flash Marlin 2.0.3 and use mash leveling, it works for me on 1.1.4 board perfectly.

Marlin 2.0.x is mainly for 32bit boards. Marlin 1.1.9 does have Mesh leveling available for it.

I have 2.0.3 running on 8bit 1.1.4 and it runs perfectly.

Oh it runs fine, just not necessary as there's no benefit over just sticking with the 1.1.x branch as most of any new major features on the 2.x.x branches will be geared towards 32bit boards that can handle the xtra processing. Honestly it would probably be better to look into Klipper instead Marlin if you're sticking with the factory/silent board as the way it works the host PC/Pi will be doing all the heavy lifting with the gcode.
