A number of things could be causing this, go over the new and the old Configuration.h files and see what changed. Mainly things like Acceleration/jerk settings and steps/mm for all axes and the extruder.by Nprod - General

The arduino might be running on USB power, have you checked if you have the D1 diode installed? Info on the wiki -by Nprod - General
Okay, the 12V solenoids just arrived and they work pretty well! They do get slightly warm when active for longer than a minute or two, but that's probably normal. Actuation force is small, so the only option when using a mechanical microswitch would be the way it's shown in the ROBO3D forum, with a lever and set up in the normally-open position. Opto-endstops probably make much more sense here. Mby Nprod - Experimental and Hobby
QuoteDalius98 QuoteLykle I am using the Engineer crimpers and am perfectly happy with them. Lykle QuoteWurstnase Engineer PA-09 I love this tool! Ok, a question for Engineer users: Did you need to use the smallest size "crimping die" (the one labeled 1.0 on PA-09) at any time? Trying to decide between PA-09 and PA-21... I have the PA-09 here, great tool! Crimping with it is more fiddly sinceby Nprod - Experimental and Hobby
Yeah, my suggestion would've been to try setting the jumper to USB power and see if there's any response. The fact that the LCD menus work is encouraging, it means that the 1284p is working as it should. Try buzzing out the USB connector with a multimeter to see if there are any broken connections. If everything checks out fine, you could try bypassing the FTDI Serial->USB chip and connectingby Nprod - Sanguino(lolu)
I looked at the ROBO3D's specs and it seems to use a regular 12V supply. My guess would be that they probably couldn't find a suitable 12V solenoid on Sparkfun or Adafruit and went with that 5V one instead. I'll give these "Shindengen" 12V ones a try (pictured). They're roughly the same dimensions and about 2$ a piece.by Nprod - Experimental and Hobby
Hey there, i'm trying to add a compact solenoid bed probe for my printer based on a design from the ROBO3D forum here - It seems like solenoid probes aren't as popular and i haven't been able to find much info on them. My main question is regarding the circuit - from what i understand an arduino board can't supply enough current to drive the solenoid, so a 12V->5V step-down board and a mosfeby Nprod - Experimental and Hobby
