Update:
I decided to get 3/4" MDF for top surface and replaced the table top moving the old 1/4 ply down to the bottom shelf of the table. The MDF came slightly larger then my table so I cut it down to size on one edge then let the 1 inch hang off the back. Everything else is square with legs and base. Create a nice wire hiding spot for the X axis.
- All motors and end-stops are wired back to a temp working spot. Using a cheap wire sleving from HD, works pretty well actually as a quick wiring job. Used the tape measure trick for the Z. Future note to self, label female pins for everything as you go. After finishing up all cable runs it makes it hard to tell whats what with multiple motors coming together on a axis.
-End stops are all wired correctly and working great. All show open unless compressed. GND = N, S = NC. X=Xmin, X2=Xmax, Y=Ymin, Y2=Ymax.
-Steppers currently not configured right and or plugged in wrong. Y+/Y- moves Y but not Y2 (and or very small ammount. Same with X, X2 does not move) Z does not move. Although through swapping plugs all motors have proved to be working.
-SKR 1.3 with 2208 UART has proven to be a royal pain in the butt. I could not get the MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop to compile at all in VSCode/PIO. Even after swapping PIO.ini env and board designation. I tryed a few diffrent firmwares off the forums here with each having there own issues compiling. (Stock marlin compiles just fine.) Ended up getting TT Lowrider SKR1.3 to compile after applying some fixes found here. ICT Avatar advice
I then found Glens SKR Firmware and merged changes that made since with my new version that compiled.
Currently I have a firmware that compiles although my LCD reads out “TMC Connection Error”. All end stops working fine as mentioned above and control over some stepper motors as mentioned above. All motors are rated for 2.0A, trying to control Vref over UART, I have not touched the manual on chip Vref.
Build is pretty complete for now. After I get everything working ill build a box and clean up the wiring to board.
I would love any help or advice you can give on getting the BTT SKR 1.3 + BTT 2208 V3 + UART working with dual end end stops for X,X2,Y,Y2,Z. Current Firmware configs are the ones linked here
