Should I up date for arduino 1.6 Or 1.8 to solve the upload issue?
Im selecting the correct board!

what changes should I make to use this firmware with the 3DTouch?

[keescools]

I have the 3D Touch from Geeetech, this never worked properly until i found a thread on another forum that said to enlarge the delay time for the sensor to allow more time react.
This is in my configuration.h:
#define BLTOUCH
#if ENABLED(BLTOUCH)
//#define BLTOUCH_DELAY 375 // (ms) Enable and increase if needed
#define BLTOUCH_DELAY 600 // (ms) Enable and increase if needed
#endif

After this change the sensor worked for me. I hope this helps someone.
I have GT2560 A+ board Sensor connected to servo pins and z-max sensor connector

What would I need to change to use this firmware with an inductive probe instead of the BLtouch?

What exactly did you change in marlin 1.1.18 to make it work on i3 pro B????

[Blisk]

how did you use pin 11 when for Z_MAX is used pin 32???

Hi wwysocki,

I have a Geeetech Prusa I3 pro B, I've already upgraded it with T8 Lead Screw and solved very well wobbling problems. Finding tedious to manually level the bed I've installed the BLTouch also. I followed the instructions for installing, wiring and Firmware changing but even if the self test of the probe is OK after, it is not working. When is going to touch the first time the bed it is not stopping to go down. So I given up to it for some time. Now I discovered your Firmware that seems perfect to me. The only difference is my mother board, I have the GT2560+4 A4988, not the X A.
I observed your 1.1.8 Firmware configuration file that has 1773 lines instead the 794 lines of my original Firmware modified.
Do you think I can upload your one hoping to see my printer to work? I would like to see the BLTouch to work, I believe the different motherboard is requiring just a different wiring and so only the pins file it is different.
If you confirm it is possible I can start a new test session hoping to upgrade my printer.

Thanks a lot

Maurizio

Hi,

I think you should be fine using that firmware I uploaded - there is not too much in the board configuration - there is one file which is define servo pins
when you will open this file pins_GT2560_REV_A_PLUS.h you will see only few files - the original fine doesn't for me as well before (the Z was never stop on G28) so what I did I just changed the pin from 32 to 11 and that did the trick for me

Thanks
Wes

hello, how to set marlin to work this way? Could you share the marlin file?
