I got everything but my end stops and heatbed wired up. Figured out how wire power supply to it found some test code that turned on everything at once and everything worked but now I'm stuck.
I can't seem to get marlin or sprinter firmware to compile to board every time I do I get multiple error messages about 60 percent of the way through. I can write code to arduino so I know that's not the issue. I went through the options and made sure I selected 33 for my board and picked the thermister. Can u guys tell me whats the best software combination to use or maybe even point me to a straight toward tutorial based off ramps 1.4

i used 0.23 got it to upload to the board now i got new issues
tried using pronterface i downloaded a pre compiled folder with everything needed to run and i can get it to connect to printer but i get this error
Connecting...
start
Printer is now online.

pretty sure its wired up correctly, it is the mkiv-b hot end however I did not see a option for that type of nozzle in marlin firmware files.

You should hunt down the info on the exact thermocouple/thermistor they use in their hotend, then apply the proper number for the proper type in the firmware. I believe the "b" version of your hotend is using a smaller thermistor, maybe it has a different selection?
Chances are whatever they are using is on that list somewhere.

ok.. I feel "dumb" now I figured out my issue was I had not set the fimrware to read temp from thermistor.
I finally got it working.
however new questions is it normal for the pololu stepper drivers to get really really hot. just from sending power to the board?
I also was testing the xyz axis I had the x to the y fixed that issue, however I started smelling a stronge electronics smell and everytime i clicked to 0.1 to make the motors jump a step they seemed to jump back a bit as well is this normal?

NO
If your drivers are too hot to touch, they are probably adjusted up too high.

ok thanks ima go do some more reading before I blow something up. I know just enough to get myself in trouble ima go do some more reading about how to adjust those and also I forgot i have not installed the jumpers on the ramps 1.4 board yet for microstepping will I want to put all 3 on each one?

also would like to have I have binding issues on every almost every axis. I don't understand it honestly. I finally got to the point that i can job the xyz axis but all of them bind at a certain point which makes no sense to me whatsoever I was very thorough in every step of building and squaring up the parts and by hand all of the parts move very smoothly. The y axis is the one thats giving me the biggist issue but when its not powered up it slides the best so I don't fully comprehend whats going on.
I tried doing a test print and my machine does nothing

If you turned he current down too much on your pololus, the motors may not be generating enough torque. Depending on your motors, it can be a fine balancing act to get enough torque without the motors or pololus getting too hot. If you have low resistance motors, you may need heats sinks on your pololus. Some people recommend setting the pololus by measuring the Vref signal. That should result in repeatable and controlled adjustments. Otherwise it can be difficult not to over correct.

I am adding heat sinks to the pololu drivers I had them but didn't have any thermal compound until today. I also figured out my threaded rod on my z axis was warped so ima see if I can get some shorter cut pieces instead of a 6ft piece hoping to find 2 that don't have so much wobble.
As much as I don't want to. I'm going to diassemble everything that has linear bearings and not zip tie them until I have the rods inserted. I feel like I could get them to free up some more if the linear bearings were more true to themselves

im at a loss. I rechecked everything I can think off its really odd the motors will go in one direction however they will go the other direction as well but only after I have clicked them the other way first and then its only one or 2 steps in the other direction then nothing.
Has to be something to do with the firmware

Connect your end stops or disable them in the FW.
