BTW, a bit of a bug on original RAMPS 1.4 is that the PSU pin tends to pull down when the arduino is unpowered, causing the power supply to turn on and get into a loop of the printer switching on and off when USB power is disconnected. This is solved by powering the arduino exclusively over USB, but that's not ideal. Has high-Z at rest on PS_ON been considered in RAMPS 1.7?by RX14 - RAMPS Electronics
QuoteMrAlvin QuoteRX14 But given I made this mess attaching just two TMC2130's to my board, I'm very interested in RAMPS 1.7! Definitely interested in testing my own board once the design stabilises. Actually I do not think that is messy at all. Jumper wires are jumper wires, and they will always add a new layer of visual impression. But I hear you: sometimes one just dreams of no-jumper-wire sby RX14 - RAMPS Electronics
I looked through the thread and I can't find exactly what changes 1.7C entails. But given I made this mess attaching just two TMC2130's to my board, I'm very interested in RAMPS 1.7! Definitely interested in testing my own board once the design stabilises.by RX14 - RAMPS Electronics
