@IhorNehrutsa thanks for doing the testing! Unfortunately, I don't have the equipment to do that kind of testing, so it's great to see how everything is working. Do you have...

Did you disable all of the closed loop interrupts and everything? That could be really hurting the performance

@IhorNehrutsa since you have an oscilloscope, would it be possible for you to test the frequency of the oscillator on the board? I was unable to find a solid value...

@IhorNehrutsa how are we doing on max update rate now? I'm thinking that it should be higher

Truly a massive performance gain. Thanks so much Ihor. It was a great help! Can I close this now? I think we meet BTT's performance at this point

If I do the calculations the other way, the maximum rate is 7.7 rps at 1/32 microstepping. Now, if you consider that a typical printer pulley is about 10 mm...

@IhorNehrutsa now I know that STM32CUBEMX says that 72Mhz is the max for the SYSCLK..... but considering that we need more performance and programming optimizations are getting harder.... I did...

Darn! Do you have any idea why the speed really didn't increase? Maybe it's the register setting for setting pins? Also, I got PID somewhat working. I really don't like...

Getting really close to hitting the desired 100 kHz that you wanted. You can definitely run at 1/16th stepping. I'll look at increasing the GPIO clocks to see if we...
