[SOLVED] X/Y endstops not stopping motors, carriage grinds motor

PaulHew

Please post you Homex.g and homey.g, lets check them!

Also, if you are going to paste text from your config, use the </> button above, where you can set bold and italics. (I only learnt this one the other day!!)

It all seems good, and was working before.

M564 H0 ;allow movement without homing

Try removing this line.

@PaulHew

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 homed

Asking the printer to move in any direction using the buttons next to the home buttons result in this error:

M120
G91
G1 Z25 F6000
M121
Error: G0/G1: insufficient axes homed
Error: Pop(): stack underflow!

RyanP

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.

Please update to 2.05 and you'll find your problem is resolved.

Your homing files are using H1/H2 which is not supported syntax in your very old version.

@Phaedrux Well spotted! We should get the forum software to enforce people put the M115 response in the first post of a thread...

Perfect. Thank you very much. I thought simply swapping boards would be ok. Lesson Learned.

I spoke too quickly. I grabbed another SD card and did the complete RepRap config tool again. Created a brand new SD card for this new board. Plopped it in. Again, same problem.

So I have done an SD card from scratch. And my M115 looks like this:

FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 2.01beta1(RTOS) ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2018-06-23b1

Im pretty sure that is the same as before.

Ryan,

You are still running 2.01beta, you need to update as @Phaedrux suggested

Get the files from here and upload to your Duet.

Regards,
Paul.

You'll need to download the 2.05 zip file from PaulHews link and upload it tot eh system folder using the DWC. It should prompt you to update the firmware.

The firmware is flashed to the board itself, not the SD card.

Thanks for confirming that. Will do that now.

Fixed. Thought I did that yesterday and was perplexed by the same firmware being reported. I greatly appreciate you help. Back to printing.

Justin

I just upgraded to 2.05.1 after having the same issue. Though, before i flashed to 2.05.1 the motors were completely silent, now they make a noise.
