Hello everyone,
My name is German, I am a teacher at a technical school, and I am restoring a cnc milling cutter from the 90/00s.
The electronics are obsolete, as well as the control software, since the PCs to use it no longer exist. Therefore, I decided to implement a control through Arduino with CNC Shield v3, using GRBL v1.1 as firmware and Universal Gcode sender for control.
The stepper motors are LIN Engineering model 5718M-05D-01 of 2.0A, and they work perfectly individually controlled, with a time between steps of 3 ms.
And here my problem, the GRBL does not allow me times between steps greater than 255 us.
My query then is:
Does anyone know if it's possible to change these microseconds to millis? if so, how?
Do you know of any other firmware that I can use that allows me to work with intervals close to these 3 ms that I require?
Thank you very much for your help, my students and the school will appreciate it.
