System restarts or fails on homing X axis from LCD #23038

Closed bmorse526 closed 3 years ago

bmorse526 commented 3 years ago

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

Updated a makerFarm Pegasus that uses Arduino MEGA and RAMPS 1.4. If X axis is over half way across travel homing fails and requires printer reset or does a full restart. Homing X works and homing Z with BLtouch works. Doing bed level works through first row (if X was close to home switch) but fails on second row. Will ocasionally work when printing a file from SD that has G28 and G29 at start. Prints without issues once started. X and Y home ING are standard microswitches. Issue only shows when X carriage is over 1/3 of bed width. Switches trigger manually with no issues. Only change from Marlin 1.0 on board previously was adding BLtouch. Movement starts toward endstop, acts like it is triggered backs up moves back toward endstop (over 80mm from switch), then errors out or does power reset on board.

Bug Timeline

On upload of bugfix 2.0.x

Expected behavior

X carriage continue movement to endstop.

Actual behavior

X carriage move part way does false trigger then errors or power restarts

Steps to Reproduce

  1. Move X carriage to far side of bed
  2. Center Y axis to bed center (more repeatable)
  3. Select home X from LCD Menu Bed is 232x232mm

Did additional testing through octoprint (raspberry pi platform) sending G28 X0 , G28 Y0, OR G28 Z0 allresult in completion without issue (starting from far X,Y edges) G28 X0Y0 completes successfully repeatedly. Entering G28 fails when X axis does false trigger and shuts down from error.

Can you provide actual config used? What type of LCD do you have configured?

bmorse526 commented 3 years ago

I changed the endstop filter threshold on and set to 3. It has not occurred since then. May have some noise being feed from stepper wiring to the X Home switch. But that setting fixed the issue. Thank you.
