You have implemented the control signals CW/CCW ?

Sorry, there is a problem with the parameter description. It should be A/B phase mode.

Thank you for your suggestion, I will add a description in future updates.

There were 2 problems with manual movement of axes:
1) If # 114 is set to Mode2 and # 45 to # 48 to values ​​below 10, a glitch occurs. You can see it on this video https://radikal.ru/video/oe38oN1KQae
For clarity, set # 114 to Mode2; # 45 - # 48 at 1; # 2020 - # 2023 to 1. If done, several steps in a row, without continuing movement, the acceleration starts from 0. If you take a step after the ongoing movement, acceleration starts at 100.

2) There is a very unpleasant glitch when I release the axis shift button on DDCSV, and the axis itself continues to move.
Unfortunately, I can not reproduce it yet, but it happens from time to time. Recently because of this, I broke a thin drill.
That is, you press, for example, the arrow to the right. The X axis goes to the right. You release the button, and the axis continues to move.
To stop it, you must press any button with an arrow. Previously, this problem was when you connect a USB keyboard without a hub, directly into the USB connector of the DDCSV.
Now with USB keyboards everything is fine. But the problem sometimes appears with the buttons on the DDCSV itself.
Think about it, maybe there's a way to fix it. If not, I will try to reproduce the conditions under which this happens.

Due to accuracy of the fpga speed planning module (currently using 24-bit accuracy), the first problem you mentioned will occur when the difference between the manual start acceleration and the stop acceleration is too large. You can try to make the stop acceleration smaller.

The second problem you mentioned should be caused by defect in your controller keyboard hardware.

Thank you. Reducing the parameters # 263 - # 266 to 200 helped (there were 600).
About the keyboard. What kind of malfunction can there be in it? Sticking of buttons is excluded.
Is the TM1638 chip defective?

Sorry if this question has been asked before : are the firmware postings in this thread also usable for the 3-axis variant of DDCSV2.1 ?

I post a new version of the Russian translation.
There are a lot of changes. In future firmware, you should use this file.

The meaning of the six settings is still not clear to me.
Please, someone explain their meaning.

# 50 "HOME signal Effective when HOME" - what does this mean?
-----
# 3 "Tool path" or "Try cutting" - what is the "Try cutting" mode? Control the program with the MPG wheel?
-----
# 218 "Cycle Start key mode selection" - where is the Cycle Start button?
-----
# 396 "Number of line" - please, tell us more about this setting? Is it needed to render the Tool path?
-----
# 109 "M Bus IO default status" - the links you wrote do not work anymore. Where can I read more about M-Bus? Where is the connector?
-----
# 5 "minimum log radius of 4axis machining" - what does this mean?

# 50 "HOME signal Effective when HOME": If the HOME signal is already valid before starting the HOME operation, when #50=0, the HOME operation will be directly exited; when #50=1, the reverse motion will be performed until the HOME signal is invalid, then In the HOME operation.
