Bltouch firmware on FT-5 r2

[RodSME]

I have been struggling for some time trying to get my newly purchased and mounted Bltouch working on my FT-5 r2. Can someone post a file with the firmware changes they made to get the Bltouch working? The changes listed in the Bltouch manual didn't work. I'm just a dumb mechanical engineer and don't know much about software.

let's start with what version of marlin are you using? what did you do to the firmware already (and did you upload the changes)?

also, what aspects aren't working? does it light up? does it actuate? none of the above?

I don't know where to find the version of Marlin I'm using. I downloaded the firmware from the Folger Tech web site as described in the setup manual, "Marlin_ft5_stock_060518". I have been using that for some time. I love the printer and it works well. I decided to add a Bltouch. The Bltouch manual was of little help. I following the instructions on the last page of the Bltouch manual by downloading and replacing the configuration and configuration.adv files. All sorts of errors when I tried to Verify. I decided to try making the changes to the stock FT5 firmware configuration file. It Verified and Uploaded to the printer. When I opened Repetier-Host V2.1.6 and connected, it showed connected. However, the printer doesn't work now. The Bltouch is rapidly flashing red for about one second, it stops for a short time and starts flashing red again. The pin is fully retracted. There are two rows of "f"s on the display and at the bottom of the Repetier-Host window there is a message, "No start signal detected-forcing start". Attached is a .zip file with the configuration file as I modified it I didn't modify the configuration.adv file, but it is included in the zipped file anyway.

Thanks for your help.

downloading and replacing the configuration and configuration.adv files

I'm guessing the versions didn't match... the stock ft5 firmware is pretty dated. It still works, but likely won't line up with the files that antclabs provided.

I decided to try making the changes to the stock FT5 firmware configuration file. It Verified and Uploaded to the printer.

what did you have to adjust here? If I remember right, it was just uncommenting a line and that was about it. linked below is my firmware for the ft5, though please do not use it directly, there are a number of other adjustments that may not play well with yours (also, it is marlin 1.1.8 which is a few versions newer than stock). you can look through it at the bltouch sections to see if you have that all set correctly. if not, perhaps you have some wires crossed?

First I want to thank you for the time you spent responding to my plea. I realized that the Marlin rev is shown on the FT-5 display. It is 1.1.2.

Just to keep you updated, The display problem showing two rows of "f'"s was because I changed the SERIAL_PORT from 0 to 2. Leaving it at zero fixed the problem.

The Bltouch is mounted and connected. I've updated the firmware pretty much per the Bltouch manual. Using Repetier-Host, sending M280 P0 S10 does push the pin down, sending M280 P0 S90 retracts the pin. Progress! Now to calibrate.

Unless you are interested, I won't trouble you with my efforts. Thanks again.

it is for:

BL Touch
Endstop testing
Bed limit and bed abjusters position
Z-probe configuration
Bed Level Tool
Scan building surface and create visual chart
Z-rod maintenance
Auto PID calibration

I've managed to get the Bltouch to work. I used SolidWorks to create a grid to print on the printer. The grid is a square pattern 9x9 of lines 0.3mm wide by 0.23mm thick, 25mm x 25mm spacing. It printed perfectly using a 0.2mm nozzle with PLA, printed at 250C on a 65C bed.

Thank you for all your suggestions and help.
