Hi motiondave ,yokoyoko,vicpopo,prodigy,kevin123, Battlestar,adbgg( x-sim and simulator builders)
In the event I forgot someone please forgive me ,
Thanks so far for all the excellent support advice ,encouragement ,suggestions and solutions I have received from everyone so far .
Just to update everyone .I have had tremendous problems in trying to find a working solution for my K8055 and Sabertooth 2DOF system.However I have followed many manuals ,advice ,read and re-read manuals ,tutorials etc and always seem to be not finding the correct solution to my problem .I have persevered with all the good advice and some real brainstorming and decided to look at various profiles in the forums ,( some written by abdgg,kevin,stephaned61,bigtalltim)
These tutorials are extremely important and excellent in content , ( Please forgive my ignorance ) however there is a lot of setup and profile and configuration information and I think it depends upon how a person`s perception is regarding how a person starts and advances through one`s project ,the outcome of the final result can either be very frustrating ,or it all comes together and not many problems are experienced .However ( although very technical myself ) this has not been the case for me .Everything I tried in setting up the software ,the profiles and trying to get the system working proved futile ,and once I started getting motors turning That is all they done ,they did not stop .Going back ,and checking ,feedbacks ,motor outputs ,percentages using the k8055 demo software ,x-sim software etc,this was all happening ,so why did I not get the results I have set out to achieve .
Well I have finally progressed a bit further and I promise to give a full posting on the x-sim site with regard to all my questions ,screenshots ,feedback I have received form everyone .I will also give a thorough breakdown of what I have experienced ,the problems encountered and the soloutions that I have been provided with or contributions made to me by members and also my own findings and will give a detailed writeup as to the sequence of events I went though .
As I did not want to break my simulator before I had even completed it I decided to dig out some items ( fortunately laying around ) and managed to find two 12volt dc motors ,some brackets ,plates ,perspex and fasteners and couplings and power supply and then adapt them to build a basic simulator of what the electrical and electronic system consisted of .Sitting next to a ready built simulator and trying to make it work is not easy or very practical as one has to stretch ,press buttons start stop ,push accelerator pedals,brakes ,clutches in short there are too many things happening or required to happen and the objective of trying to resolve the software side of things then becomes lost in this hive of activity ,the danger also exists if the main wiper /drive motors are coupled which can cause injury or even damage the system.Therefore the need for the basic dummy simulator
I have a basic avi of how the motors move with feedback to the potentiometers (don`t know where or how to post this .avi ) ( although the motors are fast they do not supply sufficient torque and therefore they do not respond quickly to the output motion ,they however do give one a good indication as to what is happenning in the system .I have also posted in my gallery a few more screenshots and photos of the basic system setup.
I managed to look at a lot of profiles and compare them to the ones I made as per the tutorials made by members as mentioned above, but they somehow they do not all work and one has to pay extremely good attention when making any changes in the profiles which can lead to many days of frustration ,believe me.
At the moment My system is working but as mentioned ,the leds on the board ,dac1 and dac2 give a fairly qiuck response as to how and when the system is giving control output to the motors ( although not moving as quick due to torque size etc as explained ) I also have a photo af the output performance graph which shows the system appears to be very responsive ,but somehow I don`t see this hppening at the output.
Am I correct in saying this or can someone please have a look at my attached photos of the profile and give me a solution to my problem please ,or any suggestion or feedback of any kind .It would be greatly appreciated.
Thank you to everyone again for all your support thus far
