[SOLVED] X/Y endstops not stopping motors, carriage grinds motor
-
Long story short, bought two Duet 2 Maestros of two Ender 5 printers. One of the boards was a refurbished board that I got a killer deal on. It worked for two months but gave up the ghost. The second D2M had not been installed yet, so I disconnected the wiring, pulled out the refurb, and reconnected the factory new one in its place. I pulled the SD card out of the refurb, and put it in the new one.
Everything lights up correctly. Jumps right back on my network. I initialized the SD card, and I can access the data in system editor. All seems good. But when I try to home all, I get an error advising G0/G1 Insufficient axis homed.
So I sent M564 H0 to allow me to move the motors. All motors move properly when instructed. They are all connected correctly, wired correctly and move correctly.
Moving to the endstops, only concerned about X and Y, as Z is controlled by and BL Touch.
I sent repeated M119 commands to retrieve the endstop state, and they are working correctly. When I manually trigger them, they illicit a response.
But when the carriage hits them....they keep on moving.
What could have changed between a simple board replacement. Any help, as I feel Ive uncover every rock.

M574 X0 Y1 S1 ; set active high endstopsX0 means no endstop. It should be X1 based on your homing move direction.

Also, don't load this in config.g
G29 S1Put it at the end of your homeall or in your slicer start gcode instead. -

Corrected this (I had fiddled around with these settings a lot before asking for help, must have gotten missed).
But this still did not help. Powered up this morning, corrected this, checked my M119, endstops are in fact working and registering change. But the motor still wants to plow on through.
Is it possible there is something stuck on the board digitally from manufacturing tests that needs to be erased? Again, I had a refurbished Maestro working fine (until it died) and simply swapped it out for a new one I had.
Thanks.

Update, hoping this helps somebody solve this problem.
The the M564 S0 in place I can manually move around the motors. So I can move the X and Y carriages to the endstops, make the click, and then send G92 X0 and G92 Y0.
This makes the "Home X" and "Home Y" on the web interface change from orange to blue. And the motors will stop when they get to 0.00 now.
But, when I hit "Home All", they continue to want to plow right through the endstops.
So while M119 is registering the endstops as properly triggered, they are not instructing the motors to stop. Basically, they are not "zeroing".
Is it possible I need to reset the board?

Please post your latest config.g
G92 resets its home position, I only use G92 when I am resetting my Z axis after levelling it.
Take the G92 out and reboot the printer before any damage is done!
@Phaedrux created some guides for the Ender3 which are extremely helpful, I use them even with a CoreXY printer.
Have you seen them?You can see the endstops triggering in DWC, under 'Machine-Specific' on the left hand side.
When you click Machine specific or the RHS there should be a box labelled 'Endstops'
If you manually press the endstop switches they should change their state.HTH

It kind of sounds like your coordinate system is a bit out of whack.
Have a look through this post and verify that you have a right hand coordinate system with 0,0 in the front left corner. +X going to the right and +Y going to the back and htat your endstop locations are reflected correctly in M574 and your homing moves are also correct direction.

Hi Paul,
Couple of things. I'm only using the G92 temporarily to create the software endstop. I wanted to see if the machine would stop at 0.00, which it does. So onto the more perplexing thing.
Since I sent M564 S0 to allow me to move the axis before homing, I can move the axis to the 0.00 point for each axis. Whether I manually trigger them, or move the axis carriages into them, they respond correctly in 'Machine Specific'. But when it is triggered, it is not telling the steppers/motors to stop.
But it did it perfectly the previous D2M board that I had been using for 2 months.
My CR10S is working excellently on a Duet 2 Wifi board. And my troubleshooting/researching skills are pretty solid, but this one has me baffled.

The coordinate system is fine. It was working fine on the previous maestro board.
Question, when an endstop is triggered, what part of the HW/SW/FW is actually telling the steppers to stop sending current to the motors?
I can hold the endstop closed, and still move the motors around. The system is simply disregarding the endstop all together.

It all seems good, and was working before.

Try removing this line.

If I remove that, and it wasn't there before this problem, the printer will simply not move.

So I uncommented that line.
Hitting Home All or any individual axis home button gives this error:
G28
Error: G0/G1: insufficient axes homedAsking the printer to move in any direction using the buttons next to the home buttons result in this error:
M120
G91

M121
Error: G0/G1: insufficient axes homed
Error: Pop(): stack underflow! -
Usually stack over flow or under flow mean there is a compiling error, to my knowledge.
-
@RyanP Please check how you have connected the X and Y endstops. It sounds like they are reversed, or one is connected to Z endstop.

Can you send M115 and verify what firmware version you're using?
Endstops are only active during homing moves (G1 H1).
Moves with G1 H2 should allow movement without using M564 H0, so this leads me to believe you are using an older firmware version that doesn't understand G1 H1/G1 H2. It used to be G1 S1/G1 S2.
