Hey everyone, So I just got my first printer on Thursday, the FLSUN Prusa i3, and after putting it all together realized that the board that comes with only has one Z axis motor connection, but two Z axis motors. They supply an adapter to connect both to the single connection but it was missing from the kit. They're shipping me a replacement, but in the meantime I wanted to try and get things upby Ynothna - Prusa i3 and variants
Quoterufinus Hello Ynothna, here how it is in my manual and on my board (RAMPS 1.4): On the right side there are 2 vertical motor connectors, they are for Z motors. Not the one horizontal with Z on top, where Z-switch is plugged. Hey rufinus, My layout is definitely different: My motors are the top connections, in order they are X,Y,Z,E0,E1. If I had another stepper driver I could use theby Ynothna - Extruded Aluminum Frames
Quoteenif Have you also tried swapping the stepper drivers instead of the motors? May be it's just the X stepper driver which does not work properly... I've been skyping with the engineer from the company I bought it from and that was exactly the problem, I didn't realize what the stepper drivers were and the one for the X motor was in the E1 stepper connection. After moving it the X motor is wby Ynothna - RAMPS Electronics
Hey everyone! I've just finished building my first printer, the FLSUN Prusa i3 with RAMPS 1.4 and have run into an issue at the very end... The connection on the board for the X motor does not seem to work at all, the motor doesn't even try to move, but when I check the resistance in the pins everything seems normal. When I swap motors around they all work, just none of them work on the X motorby Ynothna - RAMPS Electronics
Got it working! There is a variable in the Marlin firmware to turn on dual Z or Y steppers and use the next available unused extruder connection. Annoyingly, the variable was in the copy of the firmware they sent with the printer, just disabled, so there was never any need for the adapter. Oh well, both of my Z axis motors are working now. My X still isn't responding, baby steps. In case anyoneby Ynothna - Extruded Aluminum Frames
Quotefadroid Which board do you have? is it the ramps 1.4plus? (this one has 3 ports for the Z, and they are all the same, one in the regular location under the Z marking, and two vertically placed on its right side) send a picture of your board if you are not sure. It's a RAMPS 1.4 but I don't think it's a plus. I didn't notice until now, but there are 4 pins a little below each motor connectiby Ynothna - Extruded Aluminum Frames
QuoteKingDWS There are two Z motor connections on the board so is just plug and play, no need to make anything. Just look at the picture of the board in the manual (pdf) that shows where everything goes. Mine doesn't seem to have 2 connections, and the manual I have shows an adapter used to connect both motors to a single plug on the board. The only other motor plug I have is for another extrudeby Ynothna - Extruded Aluminum Frames
Hey everyone! I just received my FLSUN Prusa i3 yesterday (first printer) so I'm pretty new to all of this. I've got it all put together but seem to be missing the adapter for the Z motors to connect to the one connection on the controller board. The pictures in the manual don't show the end very well, is it just a simple joiner for the two, or is there anything fancy that needs to be done? I'mby Ynothna - Extruded Aluminum Frames
