I'm looking for a piece of code that will turn on 2 stepper motors for a certain amount of time when a limit switch is pressed. So I have a limit switch, (we will call it the front drop switch) at the end of my platen travel so that when the platen is ejected it hits the front drop switch, which turns on 2 stepper motors that lower my platen by a certain amount, via the base controller board, and then signals the AIO board to return the platen to the start position ready to print "page" 2 . Can anyone help me with this? I'm using a 1430 printer with an AIO v.2 board and a base controller board. My two stepper motors that drop the platen are attached to the base controller. I also need to know where I would connect my "front drop" switch on the base controller board. Any help would be greatly appreciated, as this is the final step to building my 3D printer!

I've not looked at the base controller or it's software but I would have thought the simplest way would be to add code so that the front stop switch is in either state 0 or 1 and each time it is activated the state changes between the two. If state 0 the height is normal and state 1 it is lowered by x amount of steps.
I would advise the end switch also has a on/off toggle switch inline so you can disable it for height adjustment.
The switches would need to be connected to an unused pin on the chip.

I saw that now is only one board available (OpenDTG AIO V2 DTG Controller for P600, R3000 and 1430). From what I see in the image, the board have only one driver. Do I need another 2 drivers for the height adjustment?

I have a board for the base controller that has 2 motor drivers.

I just have never put it in the online store. I will get on that.

I see 2 possibilities:
1. For a printer with height adjustment are needed 2 boards, one for the printer and the other for the height adjustment.
2. One board with 2 drivers is needed to control the height and the platen. One driver for the platen and the other for the height. In that case, an extra power supply is needed? Beside the motors and the board, what else is needed?

Which is the correct one?

For our Advanced printer we use an AIO controller in the Epson and that has a motor driver to move the platen.

We then have a base controller board that has 2 motor drivers on it to run the height motors. The base controller has its own power supply.

Thank you Andy!

Unfortunately I can't afford 2 AIO boards. So, I will use 3 TB6600 drivers (2 for the height and one for the plate) , 3 Nema 17 motors, 2 Arduinos (one for the height and one for the plate), one Arduino Shield V2 and one 360W, 24V power supply.
What do you think?

I looked at http://2fastprinter.com and no board is available (out of stock).

I couldn't find the code for the height adjustment. Is it available?
