How to increase the Z axis punch speed? was created by programador
Good afternoon
Everyone
First of all, I would like to thank you for all the help I received in this forum, especially from Mr. PCW. With this help, I was able to go far and achieve a satisfactory result.
However, although the machine is working, the customer wants more speed on the Z axis. I don't know if I'm already at the mechanical limit of this machine, but what parameters can I change and how can I change and calculate them to test the limit of this machine? If anyone can give me a tip on how to change the INI file to improve performance, I would be very grateful.
Below is the video of the machine that was retrofitted and working perfectly with the boards from the manufacturer Mesa.
Below is the INI code

You might try setting the Z axis velocity the same as the joint 2 velocity (125):

Good evening Mr. PCW, everything is fine, I managed to increase the speed, thank you very much. The results of the electronic boards from the manufacturer Mesa were surprising, being able to increase the speed beyond what the machine can support.
Please, can you tell me which HAL configuration component I can use to connect MAX_VELOCITY and MAX_ACCELERATION with a variable in the classicladder or using a UI grid graph in the GMOCCAPY graphical user interface tabs? The machine operator requested to be able to increase and decrease the machine's operating speed without having to change the INI file.

Might easier to just have a few configurations with different settings in their .ini files
You can change ini settings with LinuxCNC running (but interpreter idle) but setting up a GUI to
do this is outside my area of expertise.
