Sexball Probe doc issues

[Tavroswyn]

I did find some problems with the documentation for the Sexball Probe, that I partially can't fix myself or needs a decision on how to fix it. So I decided to create this ticket to track the discussion, that I started on Discord.

1. The info-box on the Calibration Tools overview page titled “LDO Kit” can be misinterpreted as in “you need an LDO kit for the hardware”. So I am suggesting to change the text to something like “LDO's Base StealthChanger Kit also includes all necessary hardware components to build a Sexball Probe.”.
2. The shaft for the Sexball Probe is too short? The original BOM for the SexBolt suggests two sleeve bearings of 8mm length. Combined with the height of 8.45mm above the switch of the mounting point for these 16mm of sleeve bearings on the original SexBolt housing, this means the bearings end 24.45mm above the top of the switch. However, the recommended 30mm shaft only has about 23.5mm length until the thread start. So if you screw in the ball all the way, the shaft does not reach the switch. There are multiple ways to solve this. I chose to just modify hartks model and moved the mounting point down by 2mm. If this would be the official solution, DSD should provide it's own stl for the Sexball Probe housing. Another solution would be to recommend a 35mm shaft instead. Or smaller sleeve bearings could be recommended. The hardware bom on the StealthChanger manual recommends a 10mm sleeve bearing, which is used for the LDO Sexball Probe I guess, but this doesn't work here, because in hartk's housing the depth for the bearings is 13mm, which means the recommended sleeve bearing does not even reach the top of the housing.
3. The Sexball Probe Ball in the CAD is shown far too high compared to the build plate. I measured in the CADs, that the distance from the switch in hartk's SexBolt housing to the top of the build plate is about 28.5mm. The hardware BOM for the SexBall recommends a 30mm shaft with a thread that starts at about 23.5mm. Therefore the ball starts 5mm below the top of the build plate. With the recommended 12mm ball, about half of the ball is below the top of the build plate.
4. LDO and hartk's model are not compatible, but are mixed in the build guide. The printed BOM references LDO's housing, but the hardware BOM says that either LDO or hartk Z endstop PCB can be used which are different and do not fit interchangeably, because the distance between the switch and the connector is different. There are also other differences in the BOM between the two with screws and sleeve bearings. Therefore I suggest splitting the guide into two, one for the LDO Kit provided one and one based on the hartk Sexbolt.
5. The Ressources tab in the build guide should link hartk's SexBolt.

1. We can change the wording to say they are "available as" part of the LDO kit rather than "come as".
2. This is something I can change in the model. It turns out the testing team received different hardware for the Sexball than what is in circulation now.
3. Would you mind sending some reference photo's for me to update the CAD. I only have a testing version of Sexball and it doesn't match. Getting the dimensions of shaft, bushing and ball would help a lot.
4. I was not aware of the incompatibility. Lets fix the LDO version that is there now and work on adding a hartk version.
5. Agree.

I can update the necessary pieces as required, I just need a bit more information on the dimensions of the pieces included with the LDO kit.
