Re: TMC2100 high pitched noise - 7 years ago
Question: Do I bridge all three points on the board at CFG 0,5,6? Or just the two shown inside the red box on your photo? Also is there a tips and tricks for doing this? I have never soldered something so tiny before.by behnt - Printing

Re: Optical end stop help Ramps 1.4 Marlin firmware - 10 years ago
Ok pins are good! Whew! But I want to clarify before I really blow pins I should take the "S"ignal wire to ground? Then should I put the ground to the signal pin? Then again with S to +5v? where do I put the +5V line when I do this? I am not convinced this will work as the stop needs constant power to operate I apologize for my newbie-ness but I guess you have to start somewhere. I totally apby behnt - Reprappers

Ugh... Ok then is it at least the Mega that is shot and not the Ramps board? I have extra arduinos... Feeling quite dumb.... Then again how do I test if the pins are live or not? Now that I am thinking this through I powered the stop with the endstop 5v so the return should have been 5v so maybe.... crossing fingers. If its burnt out then its the price I pay for jumping in I guess. Ill chalkby behnt - Reprappers
Optical end stop help Ramps 1.4 Marlin firmware - 10 years ago
I have a old chem lab CNC equipment platform (used to set up petri dishes) and it will do well for a printer. I have everything wired up and steppers moving. it comes with Omron EE-SX optical end stops. Now the problem. I have no idea how to set the code for the stops in Marlin in Configuration.h I have tried what I think are all the options of pullups and no pullups, reversing the the logic eby behnt - Reprappers
Re: 24V with Ramps 1.4 questions - 11 years ago
I am converting some old lab equipment into a 3D printer and am using a 24v system. I have done all recommended on here but wonder if I run a 12v nozzle off of D8 (heat bed) and put the 11A input to a 12v source would work? I was going to add a step down converter from 24-12 and then wire to the 11A input. I guess my question is will this work? Also I am a aero engineer not a coder or electricaby behnt - RAMPS Electronics
