Solved What controls the heat bed?

Lmao oh that feeling of being silly is back

 

So those jumpers and what we talked about before is all there is to it ?

 

Yes. Should be.

 

They just tried (apparently) to significantly reduce the extra parts count/pin count on the new style RAMPS and that can only be to try and trim costs. Even a buck a board adds up.

 

Ok so I'm wiring now. The r1+ d9 is extruder heat. This needs to go to d10 on the generic board? And the d9 on the r1+ board is the 4 wire bed heat that needs to go to the generic boards d19

 

• Swaps D10 and D9 positions, adds 2 pin connector for D10. Firmware stays the same (Pin 9 is fan, Pin 10 is extruder heater)
• Removes E1 port and reroutes the trace to use as secondary Z driver
• Adds 2 additional 12v pin outputs for LED's. Removes Aux 2 and 1

What was wired to D10 goes to D9 (and vice versa) I assume (don't have one to compare to).
On the Std Ramps mine are wired like this:

D08 -> Heated Bed
D09 -> Parts fan
D10 -> Extruder Heater

 

Thermistor for bed ?

 

That goes to a thermistor connector. Those are in a different spot (towards the back of the RAMPS).
T0 is extruder thermistor, T1 is heated bed thermistor

 

When you get this done you should document it in a MODS thread with pictures.

 

I absolutely will. A walk through would be amazing. I'm halfway there with your help

 

Hey, you at least have an R1+ specific RAMPS to compare to
And take pictures of ...

 

Lol I'm getting ballsy haha or cheap. So the z stepper drive has a dual pin, but the wiring has a single header for the single header on the r1+ boards. Do I need to just plug into 1 side of the dual pin? Or will I need to short the pins together?

 

End stops have a dual and single header together on the generic. Same question as these are dual pin headers on the r1+ board

 

Pictures of what you are asking please.
I have no idea what you mean.
On the standard ramps there are two Z stepper connectors and one comes from each Z stepper motor.

 

Hey mark,
Thank you. I'll get you pictures today when I get home at 3:30 cst.

 

The connector header for the endstops have 3 pins on the standard ramps (-/+/gnd) only the outermost ones are jumpered by the two pin header. If you jumper - to + that would be a problem

 

Ok attached are the pictures of what I have wired. Please check me over and see if I did something dumb

 

I have left the leds unhooked so far and have not put the heat sink on the mosfet yet

 

Looks correct to me.
One thing to bear in mind so I will throw it out there now (so you don't panic)... If you test a stepper and it is running the wrong way, simply reverse the connector by the stepper driver card (flip it around 180 degrees and plug it back in).

 

Ah! I would have defianently freaked out lol. Probably would have flipped the wires and freaked out more lol. Thank you! I'm going to eat then give it a whirl! Then if all is working write up a work instruction
