Four Limit Switches and the Error Still Arises...

[silver2row]

Hello,

I added four limit switches to the board, i.e. NC accessible switches. I am still getting the first starter error.

I know what the docs. say. I have read them over and over. I just added my 12v PSU, some motors, and four limit switches.

If I solder on the screw terminals, do each of the soldered on screw terminals need an I/O or can I just leave them floating?

P.S. I have started a discussion before in here but thought this would solve the issue.

The "first starter" error is due to the reset (or estop) input beeing asserted, not the limit switches. Connect it to ground or invert it.

If I solder on the screw terminals, do each of the soldered on screw terminals need an I/O or can I just leave them floating?

I am not sure I understand this... If a terminal is not connected to an I/O pin it does not matter if it is connected or not. If a terminal connected to an input pin it should be wired to ground or high level voltage (3.3V) if directly connected to a MCU pin as the pull-up/pull-down resistors are rather large in value (typically ~50K). The best is to have optocouplers between the terminal and the MCU pin.

Hello,

Sorry for my late reply. What should I connect to GND and/or what should I invert? I currently have three motors and four endstops.

I read the article on how to attach four endstops to handle this error. I have not yet made it past this error.

P.S. I am using the board and a Teensy4.1 attached to the board directly from the headers.

Did you try the estop/reset/halt input (I do not know what it is labeled on your board).
Do you get an error or alarm, and which number?

Hello,

I have not tried anything yet. I just added in the motors and endstops, PSU. I am using the GRBLhal Board from Tindie w/ the Teensy4.1 attachment.

I will look for the estop/halt input. Thank you.

I will update you soon. Sorry it has taken me so long to let you know what is going on.
