(the last post seems to have disappeared so I am re-posting this)
I don’t know if this really counts as hardware development for the MP3DP, but as the ramps 1.4 was dropped from the store not that long ago, and I am a ramps runner I thought these looked interesting.
So I am running ramps on my new MP3DP I made. I was using a relay, and I have had to run my anet a8 bed through a relay as well, but that was always annoying. Anyways, I was looking at getting some spare ramps (cause I only seem to have a 50% success rate with them) and I saw these ramps 1.6??? Well they were 8 dollars (vs the 3 to 4 for 1.4) and they looked to solve most of my issues (supposedly 270 watts and has better mosfets with heat sinks, also i like that you only have to run 1 set of wires from the power supply, no 11 and 5 amp stuff)
Anyways…. I just switched it out for my ramps 1.4 and it seems to work fine. I will play around with it some more this weekend I hope and see how it does. Does anyone know anymore about these? I bought 2 and they both work so for me that is better already than my success with ramps 1.4. The heat bed and hotend seems to heat up in good time, which was something that always bothered me in the past.
