Re: Help Wiring Large (12"x12") Heatbed Through Relay or MOSFET
Quote 1. Solder wire from + input terminal to + output terminal Yes, this takes care of bypassing the 11amps ptc fuse. This is main thing to do. This becomes so that current comes in one connector,...

Awesome, thank you! You're right, there isn't any reason to solder a wire from the + terminal to the other + terminal. I think I'll just go ahead and use the wire for the - terminal > source pin...

Yup i think 10 awg should be like overkill, so will do the job and then some :) Again full solid core wire, not multi-core multi-filar or stranded wire. Although at 10 awg it might work even if its...

Cool, sounds like a plan, I'll report back with the results when I have them!

I agree, I'm moving all my hobby stuff (printer, router, radio control) to 32-bit platforms. The 8-bit field already has many options, what we need are more 32-bit higher speed options. The Due is...

Have you tried tridprinting.com? (They just started selling the Azteeg X5 Mini.) UltiBots.com? (They do not carry a 32-bit board as of today.)

@angelo: Sorry, corrected my post, I was quoting xnaron. I think the only option for me is to use a breakout board for the drivers, and a separate power supply. I'm still piecing together what I will...

@A2 do you habe Seen my microstepperdriver? You can power it seperate (12/24/36 Volt). Also it is possible with The dipp switch full/16/32/64/128 steps. Noisless and a much better print result, but...

Fun new problem: I got the heatbed in last night and measured the resistance, and it's .4 ohms! At 12V, that's 30A/360W, which exactly what my power supply is rated for. Which means I need to add an...

Although I'm able to use my RAMPS-FD, I wish there was a RAMPS/RADDS style board that was designed primarily to interface to breakout boards that handled the power (stepper or heater). I'd really like...

Measuring resistances in that range could be kind of tricky, usually the low values are not read all that well and errors creep in. Depends on your multimeter and what errors/confidence it has. But...

I have not yet found a solution for this. But I have an idea. I'd like to swap the E0 driver to E1 and tell marlin to use extruder #1 instead of #0....maybe that fixes it... I somehow assume that...
View ArticleRe: DRV8825 tiny trouble
Do you know for a fact that E1 works and E0 doesnt, or is that just a test. If you are sure that E1 works while E0 does not, you can go in pins.h and see which pins does it use for E0 and E1, and just...

Okay, I'll check that when I get home (shorting the probes). I mean, it's a pretty huge bed, and the description said it needed a lot of current, so I wasn't too surprised (I thought it would be...
