Sounds like damaged voltage regulator When the mega is plugged into the ramps its generates 5v from the 12v fed into the vin pin of the mega. This goes threw a voltage regulator to produce 5v. Now...

I disconnected the 5v regulator on my board (because it was damaged). I plan to power the Arduino via the USB, and the RAMPS with the 12v supply. I'm not confident that this is the issue, however,...

Do I have to change anything on marlin if i use DVR 8825 AND A4988 together on ramps 1.4 board
View ArticleRe: Using DVR 8825 AND A4988 together on ramps 1.4 board
No, I use 8825 for all the axes, and a 4988 for the extruder. All you really need to do is get the steps per millimeter correct.

Auto leveling uses the Z_SAFE_HOMING position to make sure the probe is going to sense the bed. If your not using auto leveling, then Repetier doesn't use Z_SAFE_HOMING. For example, on one of my...

I'm surprised you're not getting a divide by 0 error on the change you made to the z safe homing points. If you don't want it to go to the center when homing z, comment out Z_SAFE_HOMING. Travel...
