Have you checked the temperature of the motors themselves. I noticed the same issue on mine and found it would skip steps when the motor became hot to the touch. I played with the driver tuning for a few days to no avail, so I tried adding a fan to the motor - motor is now only warm to the touch and the issue went away.

Well, I had a feeling this wasn't a thermistor problem.
Received my new thermistors today, installed one in the heatbed, changed the type (now ATC Semitec 104GT-2 ) and fired up the printer: -20deg reading on the heatbed - WTF!!!
Time to debug. Switched the pins/thermistor types with the extruder (which was reading correctly) and readings switched - not a problem with the board.
Got out the mu

How about something like this:
Inexpensive, small and shouldn't take much to wire to RAMPS board.

It looks like the layer options are now in a resizable window, and the default is too small to show the sliders.
Float your cursor just below the horizontal slider for the GCODE editor and you should be able to resize the slider window.

This does get rid of the compile error, but has the same effect as disabling the SDCard all together.
Trying to solve heatbed thermistor problem ATM, will get back into this once I have that figured out.

So I decided to try walking through the .91 config, using a generic thermistor chart and my calculated Beta value.
Temp now reads -20deg and still no display change if I turn on the heatbed. But I can now turn it on/off manually and the heatbed output graph shows power output and a blue line that goes on/off with the average temp checkbox. The top graph will show the heatbed target temperature (

My printer started going into dry mode because of a heatbed thermistor error. I removed the thermistor and found that it had split. The bad thermistor was replaced with what I believe is the same type of thermistor (both purchased at one time from same vendor, both in same bag, but no data sheets).
With no FW changes, the new thermistor shows -50deg temp - causing default.

WOOT!
With fire extinguisher handy, I brought my freshly completed Prusa i3 to life.
Here is a pic of the first .5mm wall test and the 20mm square test:
It took 3 tries to get the 20mm square, but the .5mm wall test was my very first print.
Since the first prints came out much better than expected, I printed out a part I designed to cover the power outlets on the Dell power supply that wa
