Good Morning Ryan,
First off, thanks to you and all the folks at V1 Engineering for the Low Rider 2 design, hardware and software engineering.
I’ve been using the Low Rider 2 for over a year and am sincerely impressed with its functionality and precision.
Since purchasing the hardware and assembling the machine I’ve been trolling the forums and have been able to avoid opening any new topics thanks to feedback from you and other users.
I regret that needs to change today and apologise if I’ve missed a relevant post.
Again, thank you for putting this technology within reach of this old retiree.
My machine has the Ultimachine Mini Rambo 1.3a board with single endstops (limit switches) and was working fantastically on the Marlin 425 22.214.171.124 firmware.
Yesterday I compiled and uploaded the 510S 126.96.36.199 firmware and was having some difficulty with the x and Y homing features:
When I requested either of these axes to home, they would physically jog +5mm ,update their zero position on the controller and stop.
I am not a coder, but after using M119 and reviewing the configuration.h file for both versions I noted the following differences:
Marlin 425 188.8.131.52 Homing Logic Definitions
648 // Mechanical endstop with COM to ground and NC to Signal uses “false” here (most common setup).
649 #define X_MIN_ENDSTOP_INVERTING true // Set to true to invert the logic of the endstop.
650 #define Y_MIN_ENDSTOP_INVERTING true // Set to true to invert the logic of the endstop.
Marlin 510S 184.108.40.206 Homing Logic Definitions
658 // Mechanical endstop with COM to ground and NC to Signal uses “false” here (most common setup).
659 #define X_MIN_ENDSTOP_INVERTING false
660 #define Y_MIN_ENDSTOP_INVERTING false
After changing lines 659 and 660 from “false” to “true” and re-compiling this version seems to works well now on my machine. Is this worthy of a change to the GITHUB image?
I have two questions for you at your convenience:
- Could this change implemented by someone who DOES NOT undestand all the logic in the code (me) have other negative ramifications to the operation of the machine?
- Is there any simple way to change the polarity of the knob on the Full Graphic Smart Controller? In 510S, the knob requires a CCW turn to effect positive motion
on any axis. This was not the case in version 425.
Again, many thanks for your dedication to this technology.
