Category: Basic Configuration
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
