Hello everybody!

We all are tired of cheap RAMPS with burned connectors, overheated mosfets, and damaged electronics.

So, i decided to make a solid RAMPS with quality power connectors, powerful mosfets, and protection diodes.

The power connectors are original molex rated at 15A.

The MOSFETs are toshiba, rated at 70A of constant usage, with a very low resistance. They keep at low temperate for hours of printing.

The protection diodes will protect the electronic from the stored inductance on the heat bed and extruder.

This board had a huge success in the spanish reprap community during the 2014, with hundreds of units already shipped.

I choosed tindie to share this product in more countries. Tindie is a great platform for indy and amateur projects.

I manufacture the boards here in Spain. All the boards are cleaned and tested before shipping.

Please, feel free to send me your questions and comments.

Thank you!

Are these capable of 24v out of the box?

If so at 24v can it heat a 24v 300w bead to 120C without need of a relay?

The toshiba transistors will support 120V of voltage, but the arduino mega voltage regulator will get damaged with such a big conversion (it is a linear converted that transforms voltage difference in heat)

from arduino.cc :

Input Voltage (recommended) 7-12V
Input Voltage (limits) 6-20V

Not 120v 120celcius bed temperature. 24v components and optional Arduino power isolation are in high demand as this decreases heat up time and allows lower currents for Steppers and drivers.

Also a switching regulator would be a much better option.

i agree, the RAMPS design can be greatly improved. I will note this for future custom boards for 3d printing.

i said 120V because it is the max voltage of the toshiba mosfets.

I should say that people in the reprap community is telling me that they get faster heat with this board, probably because the low resistance will allow more current

Both my ramps are Dead. Haven’t replaced yet… So my printers are down. Ugh I want to print again…

There was a G+ thread on designing a RAMPS 1.5…here:

@Javier_Loureiro you kept the poly fuses in the redesign?

11

This is not a redesign of the RAMPS. It is the RAMPS 1.4 with powerful components to support long hours of printing.

12

@SirGeekALot hope we can improve 3d printing electornics for the future. The most interesting part is to get feedback of the actual issues and what really need to go futher

Nice job. Consider taking your experience and doing a smoothieware version of this. I can help if u wish.

Looks fantastic!. I admit I’m growing weary of seeing a constant flow of regurgitated cheap Chinese garbage being fed back to us cash strapped US consumers. I often wonder if the opensource movement I’ve been a fan of is actually just a big, free handout to China’s already booming economy. Keep up the great work!

The FETs are the first low hanging fruit on the RAMPS design. The second is the PolyFuses. Replace them with standard automotive style fuses and you’ve got 90% of the issues with RAMPS licked.

I’d try this but 15.00 to ship to US? No thanks.
