Re: Axis Calibration
Do the axes move in both directions on only in one direction. If they move infinite and only in one direction perhaps its looking for the endstop? The values for steps per mm in config file are correct?

Awesome! Thanks for the clarification, Noobman. I think I understand most of what you are saying... I'll take the rest on the faith that you are smarter than me. Thanks again.

I'm surprised that someone hasn't made a 3d printer controller from an Arduino UNO yet. To my knowledge, it should be possible to use some of the analog pins as digital pins. This would allow you to...

You can use only one endstop pin for all 3 of them, connected in series, if you set firmware to home one by one, and after homing one to move out of it so it is in continuity again.

Q's: 1. Since most of the communication to the stepper drivers is done via SPI, is there any clock syncronisation used to ensure all the steppers step at the same time, or are you simply relying on...

Hello, A: 1. The SPI driven DICE-L6470 has also a "step clock" signal, routed to the available GPIOs, so it is possible. The DICE has to be configured in advance and can be clocked independently or...
