I was printing the control Panel on my Eustathios 2 and realized that my X is inverted on my prints. This wasn’t apparent when doing simple tests and non-engineering pieces. I’m using RAMPs 1.4 board and running Marlin and have not been able to get this corrected.
I’ve checked and my hardware is mounted according to Eric’s Solid works model, with both x & y at a single corner. Both X and Y are connected as MIN. Any suggestions?
Check the wiring to the stepper. You can reverse directions in the firmware. Configuration.h
You can also reverse wiring on most stepper config but not all. E.g make wires 1234 reconnect as 4321. Always change stepper wires without power. Don’t unplug steppers if there’s power in the system
I’m using Ramps 1.4 on my Eustathios and here is the relevant part of my configuration.h:

The print head should home to the front left of your machine if everything is done correctly. If it doesn’t, flip the direction of the stepper motor (either wires, or through config) and move the endstop.
@Ted_Huntington thanks. When I get home I will compare with my configuration.h. I did try reversing the motor, but ran into a problem with the homing switch.
Found the solution. The X and Y motors were reversed as well as the x and Y endstops. Prints pretty darn good now.
@Rick_Sollie can you share your Marlin configuration. Using Marlin with my Prusa works like a dream. With my Eustathios (in progress) I get the impression it is to slow create speed in the X and Y axis. Using 1.8 degree steppers and 1/16 micro stepping.
I use .9 degree steppers

@Rick_Sollie , thnx a lot. is almost equal to my configuration. Btw, using 0.9 steppers as well. Will first realign the gantry to make sure friction becomes as low as possible. Otherwise move to 1.8 60mm steppers that should bring a higher torque.
