Hi there!
I’m developing a software for a project similar to the Thor. I’m using GRBL firmware. I have started from steppers connection and them work correctly. But, when I connect optical limit-switches to Arduino’s Mega 2560 pins, written in cpu_map_atmega2560.h file these limit-switches don’t work. So, perhaps, somebody has a similar problem with limit-switches or knows, how to solve it?
Hi Angel LM,
currently I am facing two problems with the Limit Switches.
First, one layer of 3D Print is not dense enough to trigger the switches properly -> I had to put the whole arm apart, but after a short Fusion session, I could design more dense onto discs.Now I try to run the homing command, but by now without success 🙁
Any idea how to fix this?
Running $H only ends in a alarm.
Running G28 moves the stepper for A for around 360 degree, but also after that the system stops.If you have any hints, I would be pretty thankful 🙂
As long I read the code and try to understand the implementation for homing.Regards
PhilippHi EleKoPhi!
Could you please share your $$ settings? To see the these settings just send
$$via Serial to the Arduino and it should send them back to you.Hi Angel LM,
I had to invert the limit switches.
After doing so, everything worked fine.Last remaining issue now, is the correct control of Art5 and Art6.
But i think this should be solvable 😀For the 1. tests, I modified the code of Asgard to run Thor as expected.
