Marlin 1.1.8 with BLTouch for i3 Pro B - with T8 Lead Screw

[wwysocki]

Hi

If you guys interested here is latest Marlin Firmware I prepared for my Geeetech i3 Pro B with BLTouch bed leveling sensor. My printer is using GT2560 A+ motherboard - using pin 11 for BLTouch (original firmware is using pin 32 but it doesn't work on my device). Spent a lot of time troubleshooting issues, calibrating but finally was able print good objects !

My previous post https://www.geeetech.com/forum/viewtopi ... 20&t=60548 was for "stock" Geeetech Prob B printer with BLTouch probe - right now I upgraded my printer and replaced stock Threaded Rod with T8 Lead Screw - huge improvement ! ( please note that I'm still newbie in 3D printing hobby so something which is HUGE for me might be nothing for you Pro guys :-) ) but anyway - below link for new 1.1.8 Firmware for Geeetech i3 Pro B printer with BLTouch sensor and T8 Lead screw

Again as always I would like to send Big Thanks to Olimatou who uploaded his modifications for 1.1.4 Firmware ( https://www.geeetech.com/forum/viewtopi ... 20&t=19846 ) - I doubt I will be able prepare 1.1.7 and then 1.1.8 without his guidance in previous version.

Latest Update 02/25/2018 2:13 PM CST ( REMEMBER this is for printer with T8 Lead screw ! )

Wow!Thank you for sharing!

No problem - hope someone will find it useful :-) - that upgrade was worth all the money and time I spent on it - prints are much much better than before :-)

I agree with your point.T8 is more stable than M8 rod.

@wwysocki, I recently contributed a couple of example/reference configurations to branch bugifx-1.1.x of the official Marlin repo. It'd be awesome if you could just add yours there: https://github.com/MarlinFirmware/Marli ... %20Pro%20B

Note that there are two versions: with and without bltouch. But there is none for T8 Lead Screws, both are for M8 rods.

You must select the correct board... go to "tools" --> "board" --> Mega2560

I have the same issue at this line and I have the correct board. anyone knows what happens?
