What is your stepper current for each stepper driver. Can you easily move the Z_Axis with your fingers by turning the Z_Axis lead-screws or couplers. configuration.h would be helpful.by Roberts_Clif - Prusa i3 and variants
Quotemagnetos thank you Robert, i will test with a 1.395 volt on the drv 8825. i was afraid of fry the drv or the motor. will test later.. I would not just jump to the 1.395 v ref, I would adjust the voltage up until steppers function correctly. This should occur around double the V-Ref as a single stepper. I have installed heat sinks on all drivers, and using a fan to cool the circuit.by Roberts_Clif - CoreXY Machines

OK, When I bought a Reprap DISCOUNT SMART CONTROLLER to replaced if with my MLCD2004 the cables needed to be turned 180 dregrees. In order to have the correct pins connected to the correct pin assignment.

As stated from first post QuoteRoberts_Clif To stay withing the bed boundaries I choose too use a 20mm side boundary and a 25mm front to back boundary from bed edge As my proximity sensor is exactly 25mm directly behind the nozzle the following chart is used for a 220mm X 270 Bed. Location 0,0,0 the nozzle is touching the front left corner of the bed. Quotedc42 Cartesian printers it is commby Roberts_Clif - Reprappers
My 3D Printer location 0,0,0 is in the front left Corner of the bed, Edge of the Bed front and left. I have no area outside of the bed that the nozzle can travel. My Printer nozzle cannot travel outside the bed area, there is no physical way without breaking the endstops. It was designed and adjusted this wayby Roberts_Clif - Reprappers

In my understanding all measurements are made from the center of the Nozzle to the center of the detection area of what ever device you are using to detect the bed. On my 3D Printer the proximity sensor has a small area on the front of the sensor (shape 30mm x 10mm x 6mm ) of which only a 4mm circle in the front can detect the bed. (Sensor is a TL-W3C2 Omron ) To stay withing the bed boundaby Roberts_Clif - Reprappers
I had and solved this problem. I have an aluminum frame 3D Printer and routed the LCD cables alone the T-Slot covering them with Aluminum Foil Duct tape from my local Hardware store. First I found the route that gave me the least amount of interference, Which was at the front of the printer. Then I ran both cables alone the T-Slot.

Thank You I have determined that there are two different EMERGENCY STOP buttons, and I was using the one that is in the file menu on top. Not the one you circled. I also stated using collapse plugin to allow the EMERGENCY STOP button to be visible at all times.

Using the thermo-coupler with the AD595 amplifier board means you have a positive and a negative leads, reversing the leads would cause the the Ramps 1.4 to miss understand the input as shorted (zero ohms). Pins 1, 4, 7 and 13 are ground. If you trace the ground power wire to the output you see that this wire has to be wired to ground, the other is wired to thermister input to ramps 1.4 circuby Roberts_Clif - Firmware - Marlin

I have a Ramps 1.4 compatible controller where the driver are directly soldered to the controller board... Though I have component level troubleshooting experience of electronics. It sound like you may have a defective A8994 driver control board. This could be simply because of a solder ball or a cold solder connection causing the controller to make the erroneous movement.

I wish I new what to tell you, althou you have been 3D Printing 3 years longer than myself. I know you have tried all the X,Y and Z Stepper adjustment calibrations. which is strange as the test cube was printed smaller and then the sample part was printed larger. This could be print speed, loose GT2 16t gears, loose X and Y-Axis belts, old stepper motors, Low Stepper current, loose nuts on the fby Roberts_Clif - General Mendel Topics
Not sure if this is what you are looking for, will post it for your consideration anyway. OctoPrint using a Raspberry Pi seems to be the way most are going, it will allow you to slice the G-Code with your current slicer then you can simply upload this G-Code to OctoPrint for 3D Printing. Raspberry Pi's OctoPrint is not the only micro computer thou it seem to be in my opinion the best solutionby Roberts_Clif - Controllers
