Wiring done

in Proforge 3 Assembly

Just as a heads up for those with the Octoprint upgrade: there are no mounting holes for the 5V to USB converter…

you also have to bend the camera mount

Thank you for the help. My wiring is now done also!

Thank you for the answer. I've connected the extruder here: black wire. Is it right?

I would connect the "5V to USB converter" here:

Is it right?

An other question is the position of the jumpers under the blue heatsinks. Is it right in manual?

My board was pre-configured like this:

Thanks a lot!

@walentin s your cables look alright. Take out the jumpers that are on your board right now and only connect one per Stepper Driver as shown in the image you posted

@walentin s well, the positive cable of the converter you have to connect on any of the positive terminals on the PSU and the negative to any of the negative terminals, it’s just as easy :)

For the stepper Cable, the red arrows point to the Stepper Driver and to the extruder cable.

That’s my wiring so far, but I'll Solder the cables for the two Z-axis a bit shorter because one of the two came damaged >.<

I ordered without the PI upgrade and used my own and so far, it looks like the board delivers enough power to run the Pi. In a few days I guess I’ll see, how it runs when the second screen is connected :-)

Good to hear that you can power Pi off the mainboard. Which Raspberry Pi are you using?

@Gregory Zilber I’ve got the 4B. powering through the board is possible, but I recommend switching to a buck converter because the board delivers a bit under 5V. Did that too and I am very glad I did it :)

I'll drill a hole then. Seems nicer. Haven't received mine yet btw. I was expecting the firmware to already be done though with 2-3 months of delay....

@Akisame - shouldn‘t be a problem since the endstops trigger before a crash with the lead screw.

If you have an M3 nut left over, you can drill a hole. I’ve fixed mine temporarily with zip ties.

What do you recommend? Drilling some mounting holes or double sided tape?
