[adamfilip]

adamfilip your printer looks great! Coming along nicely and getting the little ones involved! Well done!


Man an all of the painted printers look fantastic! I really wish I had done that looking back.

Thanks. and you still can.. if your willing to dismantle

Haha very true! Since I keep telling everyone on here how much I enjoyed my build, why not do it twice right?

What I did on my 8-inch printer is move the Y-endstop to the motor-end of the rail as well, and no firmware change was necessary after flipping the two motor connectors 180 degrees so the motors were reversed. What this did was move the home location from the right-rear to the front-left. I preferred the front-left corner as home anyway, where it is easier to wipe away any filament priming before a print starts, and this way the orientation of the print on the bed is the same as it is in Pronterface and Repetier-Host.

stupid question: wouldnt flipping the motors. make them run in reverse. wouldnt the print be mirrored or something ? lol

This is why you do both X and Y. By reversing both, you essentially just rotate the print 180 degrees on the bed.

Staring to wire things up.

the instructions are confusing.

"Heat Bed Relay

The 10” i3v heat bed requires more power then ramps can handle. Because of this your

kit has shipped with a heat bed relay we are going to connect the heat bed relay to D8 and
connect the heat bed to the relay.

DO NOT CONNECT YOUR 10” HEAT BED TO D8, THIS WILL DAMAGE YOUR
RAMPS AND VOID YOUR WARRANTY."

Why say plug into D8 and then say dont..

...Why say plug into D8 and then say dont..

So that MARLIN can control the heat bed relay, the relay coil is wired to RAMPS D8. The high current wiring for the heat bed goes through just the relay. This may help - Clarifying i3/i3v heat bed and heat bed relay wiring

[beerdart]

The relay goes to D8 and the other side of the relay goes to power supply and heat bed.

[adamfilip]

I misread it.

I thought at the end it said.. dont connect the relay

Can I flash the Rambo with the USB connection to the comp, after i wire it all up to the the power supply and motors or do i need to do it before.
