Hey guys and gilrs, I am not Happy with my Ramps Board, no thats not true, Iv got my 3rd printer running with my realy first Ramps 1.3 but came to a point where it realy got messy with all the spi headers on the #tmc2130 …
i did not find a new Board within my price range so i
MADE ONE…
currently im in testing an if someone is interrested in a prototype I could Order a few more and send dem out ~12€ in europe
its a RAMPS alike board wit more fans (5 externals up 1A) and 6drivers (tmc2130 integrated spi,cs&config 2servos 4thermistors eeer… no Display at the moment… anyone interested?
the Git is there https://github.com/workheart/Ramps-1.6x
Firmware??
Potentially, but I see a lot of these so called RAMPS replacements which are quite space inefficient.
IMO there is no point in creating another 8bit compatible RAMPS board.
Control logic needs a minimum of 2A at 5V to keep up with extra loading on those lines.
More importantly, it needs to be designed with a 32bit micro as the basis for a stackable 3d printer controller.
You could just do the RAMPS 1.4 specifically for the TMC SPI drivers, and upgrade the piddly 1A to a 2A version.
While you are at it, replace those fuses with automotive blade fuses.
Also fix the thermal relief on the ground pads.
@Javier_Prieto Firmware Is stock Marlin, just changed Pins.h
@Gary_Tolley_Grogyan Fuses are alredy replaced, and it is only 3cm longer than original Ramps, i dont do Delta so 8bit is completly okay for me.
but what is that piddly? you are talking about?
@Este_ban_S the 1A regulator on the typical arduino reached capacity for normal voard logic, and 5 drivers. so any more drivers andbthe LDO blows up. which is a problem, especially if people use the bltouch. 8 bit suppport is effectuvely dead, and 32 bit processors are the norm
okay good to pint out, never had problem with 5drivers plus 3externals, but i dont use servos and bltouch, so i could add a 5V Rail “independent” to arduinos Vcc or better i dont use Vcc in but use a seperate Vcc… no that does not work eerr----
you have to switch the linar voltage reg- on the arduino i guess.,. right?
@Este_ban_S just use the Einsy RamBO as reference, that us a well planned and laid out board
