OK, I will take your advise and use the latest code. Where is the best place to obtain it?
I will share the STL files, however I am still working on the design to see what works the best. I have just printed a new design that I haven't tried out yet and will probably have that all tested within the next few days. With the current hardware design it does work, however I have noticed that there is some deflection caused by the extended arm of the X axis (becomes a long lever) and that causes a small amount of flex while probing. To overcome this I have re-designed to give much less pressure while probing.
When I have tested and found the improvement I will post the STL files. Photos are a way of seeing how it works and I have posted several in another few replies already in this thread.
The test machine is a highly modified SmartRap. The SmartRap uses fishing line for the drives of both X and Y. I changed that to use GT2 belts. Also the SmartRap uses a servo and RAMPS for the auto bed leveling. I have changed that to use Printrboard (because I have a lot of them left over) and no servo.

This machine is using RAMPS, servo and the old Marlin code.

This machine is using Printrboard, no servo, old version of Marlin.
This is the very first test print with settings as in the uploaded firmware files. (old Marlin)
Both machines are using my design of extruder that is geared while the original machine design uses direct drive extruder.
All these machines use a Bowden delivery system for the filament feed.

There are two micro switches. One is for the X limit and the other is for the Z limit and probing
The yellow zip tie is for tying the loom to keep the wiring tidy.

Please explain to me how to...
