So I went to my parts chest. Found an epic controller updated firmware to 42 the newest and bang I got action on the t21. with the s19 psu. single phase
I also found buss bars from a s19xp that fit. So altairtech sent me short/misized buss bars.
Still fucking with the software. but I do have single phase psu working.
So I needed an epic controller I had one cost is 155
I needed buss bars I ordered one and got one that was too short I took bus bars from the s19 xp I have been modding
I used a new s19 psu I could have used the one that is on the s19xp
Since I have two more coming it is not an issue that I paid for parts.
I will ask Altairtech why I got the wrong buss bars.
based on what I did I actually think that the t21 could fit in the 1 board s19 build I did
