Hey everyone, I have a Monoprice Maker Select V2. I just installed a Ramps 1.4 board with an Arduino Mega 2560 and flashed the most updated version of marlin. Originally I was having some Y axis issues so I got another ramps. Now, when I turn it on it homes all axis' fine, moves the Z up and then down to min endstop no problem. But then once I use the scroll wheel on the LCD or Prontedface to issby ZackRP - RAMPS Electronics
After some experimentation here's the situation. When I start the printer and home, it homes up and then down to the min endstop, just like normal. Then if I start a print the z axis doesn't move up during. The LCD screen indicates that it thinks it's moving during the print, it just physically isn't. When I use the control knob to manually move the z axis up, it does nothing. It hums, like it'sby ZackRP - Firmware - Marlin
Alright well new board comes in, I hook everything up, flash firmware and it homes, but then it seems like the Z axis has an issue now. The Z motors wouldn't respond to up commands at first, and would only go down towards home. Now, if I go up, they just shake like they're at the min endstop trying to go down, and if I go down, since they're already at min endstop they shake the same, only much mby ZackRP - Firmware - Marlin
I did try the bugfix, which didn't change anything, and I've got a new board on the way, should be here tomorrow. I'm hoping that's the issue so I can just get this thing working! If not I guess I'll also replace the Arduino before going back to firmware as the issue.by ZackRP - Firmware - Marlin
After further experimentation it seems like the y axis just doesn't 'remember' when it's at home or not. If I try to print a small circular object it starts right how it's supposed to, and then the y axis continually moves away from min endstop until it reaches the end of the frame and starts grinding the belt, never moving back towards the min endstop, until I shut off the printer off and re-homby ZackRP - Firmware - Marlin
Thanks again for the reply! I switched it, and re-uploaded the firmware but get the same result. It homes perfectly fine when I first switch on the printer, but every time after that it moves 10ish mm away from Y home, and then stops, like it thinks it's always -10mm from home after that point. Then homes the other 2 axis' fine. And no matter how many times I try to home after the first home at sby ZackRP - Firmware - Marlin
Thanks for the response, I did switch connectors for the x and y axis on the board and the problem does switch to the x axis when I do that. I also tried just taking off the x and y end stops and switching them as well, but the problems remains, which is what leads me to believe it's a firmware issue as opposed to the end stop itself.by ZackRP - Firmware - Marlin
I just recently upgraded my Monoprice Maker Select v2 to a ramps 1.4 board because my melzi fried. I have been trying to upload the firmware but I'm consistently having this issue. I'm using the newest version of marlin as well as the arduino ide, and I've got ALMOST everything working, except my Y-Axis. When I first turn on my printer and hit 'Home' the Y homes, then the X, and then the Z. And tby ZackRP - Firmware - Marlin
