Hey, is anyone else having problems with the FT 2004 LCD display? Mine just shows gibberish (I have attached a picture), and I can't figure out if the display is defective, if it's a problem with my firmware, or if it's something completely different.by ACoffin - Prusa i3 and variants
Hello, I will preface this by saying that I'm just getting my first printer working, so I am definitely no expert. But I was having this exact same problem earlier this week, and I just got it fixed. It turns out that my stepper driver was set to a much too high voltage (I forgot to change it from the factory default). This caused my z-axis motors to pull too much current and shut off, then thby ACoffin - Prusa i3 and variants
QuoteDust You need a voltmeter to measure the voltage over the sense resistor, from the voltage you can work out the current. The current sense resistors should be 0.1Ω You need to know the current rating of your stepper motors. Let say for this example you have 1.7amp stepper motors Normally you only want to run about 70% of max current The maths is Vref = I_TripMax / 2 Vref = (0.7 x 1.7by ACoffin - RAMPS Electronics

I just finished putting my kit together, and I am now tuning the stepper drivers. What is the current rating for the extruder motor? It looks the same size as the motors for the X and Z axes (I believe these are 0.4A motors), but I wanted to confirm if that was really the case. Also, when tuning the stepper driver for the Z axis, should I double the Vref since it runs 2 motors?by ACoffin - Prusa i3 and variants
