Controller for my larg format 3D printer
-
We have finally come to the end.
We bought the electronics (from the Italian dealer) and it arrived yesterday morning.Before moving on to the assembly, however, I wanted to create a wiring diagram of the connections, to be sure there are no surprises.
I would like to know from you if it is correct or if there is any error.
Then I have questions:
- 12 volt 30 Amp or 24 volt 15 Amp power supply?
- Is it possible to install the electronics and relative display on a "console" external to the printer and connected to it with a cable of about 2 meters? I mean ... can the length of the connections affect the correct operation of the printer?
Thank you

Just for your information it is perfectly feasible to have multiple Z endstops.
On my printer I have 3 Z steppers each with their own endstop.
When homing using the endstops the firmware runs each Z stepper until it's associated endstop is activated.
BUT I also have a Z probe which I can (and do) use with Auto Bed Leveling (ABL) to insure the bed is level as possible.
Now it may be that I have the Z probe configured wrong but I can home Z much faster using the endstops than I can if I configure things to home Z with the Z probe.

I forgot to mention that with firmware v3.2.0 there is a problem with multiple endstops that occurs under certain circumstances.
I use v3.1.1 and it works just fine.

Thanks so much.
Beautiful ... 4 Z limit switches, at the moment, are ideal.
I have to connect them to the E2, E3, E4 and E5 inputs of the Duex5, right?Correct?

I also forgot to mention that the cause of the problem with v3.2.0 has been found and a fix is being devised.

M574 Z1 S1 P"!duex.e2stop + !duex.e3stop + !duex.e4stop"
Yours would look like...
M574 Z1 S1 P"!duex.e2stop + !duex.e3stop + !duex.e4stop + !duex.e5stop"
BUT you may or may not need the ! character. It depends on your actual endstop sensors. If you find that the firmware reports the endstop sensors are activated when they are not then add/remove the ! character as needed to achieve the desired behavior.

That issue is now fixed. The fix will be in the 3.2.2 release.

I would nominate you for a Nobel Prize if I knew how.
Thanks.

Please:
I have two questions:
-
12 volt 30 Amp or 24 volt 15 Amp power supply?
-
Is it possible to install the electronics and relative display on a "console" external to the printer and connected to it with a cable of about 2 meters? I mean ... can the length of the connections affect the correct operation of the printer?

Yes there are going to be some distance limits. It might be a better idea to have the electronics on the printer itself and then use the network to interface with the Duet. Then your "console" just needs to be a computer device with a web browser.

24v is preferable for a number of reasons, but your heaters and fans must be compatible. A buck converter can be used to provide 12v for fans at least.
