Hello everyone
I'm doing a Delta Robot, like the one in the picture (link), for use as a 3D printer.
The robot is driven by brushless motors 3 Nema 23 with its driver. This driver has the direction inputs, Step, etc. and it can optionally be controlled by USB. (The driver of the seller said that can be controlled by macro
My problem with the project is: I can not find a control board and a software for controlling the robot;
does anyone know how I can make it work?
Thank you!!

Hi,
Without knowing or seeing the drive you have, I am going to guess it's a Chopper drive (constraint current drive) Way back in the olden days (the 80's and 90's) I used a few chopper drives to power steppers. The ones I used, had one of two methods to move the steppers. One: Pulse per step and Two: PWM. Both methods had a pin or pins for setting the direction (TTL HIGH or LOW) The pulse per step, was a same speed controller (had a pot or buttons to set speed) Each pulse you sent (TTL HI/LOW) would drive it one step. These are less common now. The other was PWM. With these you send a PWM signal out via a TTL GPIO (using the analogWrite for arduinos) and that would control the step. It has been a long time though, so take this as direction for further research and not law
