Keeping my configuration values and moving to RCBugFix branch resolved my issue. I suspect that there are some regression issues in RC7, so I filed a bug on github.by base7 - Firmware - Marlin
I am having a small issue with the autoleveling G29 command. I have a delta printer and added an allen-key z-axis probe. When the G29 is issued, the printer will move to the Z tower and properly deploy the probe. The printer then probes the bed, but when it goes to store the probe after probing, the effector descends until the z-axis probe switches, and then the effector immediately begins movby base7 - Firmware - Marlin
Looking at the schematic for the RAMPS board, I now understand why the defective driver killed my 5V regulator. The step selection jumpers have a raw connection to 5V, there is no current limiting resistor in place. 5V was brought into the defective chip which then had a pathway to GND that required RESET and SLEEP to be shunted, as is the case when it is socketed in the RAMPS board. OOPS. Iby base7 - General
Thanks. My concern was that Vin would still be powered with 12V from RAMPS board and the 5V regulator would still be putting out 5V. Also with USB hooked up, I was concerned that there might be an issue. I'll take a look at the Arduino Mega schematic to be sure. I blew up my first Arduino Mega, interestingly enough the 5V regulator instantly popped when I applied power. Turns out that I hadby base7 - General
Thanks. I am running only the RAMPS board, no LCD. I haven't hit it with my temp gun, so I can't tell you what temp the regulator package is running at. As far as removing the diode, is there only a modification made to the RAMPS board? Does the Arduino need any mods?by base7 - General
I have an Arduino Mega mated with a RAMPS 1.4 board. I notice that after a while, the bottom of the Arduino board directly beneath the 5V regulator gets very hot. I followed a guide that uses the Arduino's DC barrel jack for power input and an additional wire is soldered up to the RAMPS board to carry the 12V load. I have also verified that there are no shorts or stray connections, and the outby base7 - General
