External drives limited at 25Khz

I have also uploaded a ss from Saleae Logic analyzer, you can see some of the pointers and the measurements that I took from the signal on the right side.

Which firmware version are you running?
-
Firmware is 2.02RC5(RTOS) (2018-11-28b1)

you should update to 2.02 at least. there was a bug that would impact long running prints.

OK, so, I have upgraded to the latest 2.03beta3 (2019-03-25b6) firmware. The problem continues...
Here, the signal is at 25kHz:
Here the signal is at 27kHz, where you can see the 1.36us signal, which creates a problem:

Here is the config file:

Think I found it, correct me if I am wrong:
I changed M569 P0 to P5 and P1 to P6, this seems to have fixed the issue...will test

That's right, assuming you are using the first 2 sets of step/dir/enable signals on either the expansion connector or the expansion breakout board.

I guess thats because the reprap configurator has a problem, because I did select the correct board and the correct external motors 5-E2 and 6-E3 but, it still appoints P0 and P1 in the config file. I guess you might want to report that.

Thanks, we'll get that fixed.

Thanks, it looks like the configtool was using logical instead of physical drives. It's fixed now.
