Amazing! It is now working again! Thank you so much for pointing this out - I could have sworn I did the upgrade to 3.0.0 first, but apparently not!

Looks like PEBKAC and issue now appears to be solved, so please accept a virtual beer from me :).

@JoergS5 I managed to fix it and am currently printing a calibration cube - will let you know how it goes but looking good so far...

Thanks so much for your help - it has been a long journey to get here!

@Phaedrux Embarrassingly, I didnt realise that my previous M303 hadn't been stored, so the heaters weren't actually configured!

Unfortunately, my cubes are printing with a backwards lean, so have raised another question to see if anyone can help.

The best thing is that this is all in preparation for transitioning from a prusa clone to a hypercube evolution, so I can imagine I will have a lot more questions to ask again once I start using the new build!

@T3P3Tony Hi, I did calculate them initially on the reprap configurator, but Y was slightly out of whack (possibly due to belt or build).

An adjustment of -10 steps per mm seems to have worked perfectly, though I admit I know far less about this stuff than almost everyone here

Hey - thanks for the responses!

I am attaching a few different images of the most recent cube to show the lean:

As you can see, it seems to start off straight and develop the lean after about 1/5th of the print.

I shall check angles on the frame and hardware (I only have spirit levels and an inclinometer) and see if I can spot anything.

Could this be anything to do with my config?

Hi all,

Bit of a strange one for me here. I have finally managed to get to the point where I can actually print (it's a big deal for me! ).

I have started with calibration cubes, but though I have gradually managed to improve the overall quality, my prints are leaning backwards.

It started off quite severe until I slightly reduced Y steps per mm (160 to 150), but I'm concerned that if I reduce much further I will screw my whole print geometry. The lean is reduced now, but definitely still there.

I have gone to great lengths to ensure my bed is as level as possible - does anyone have any other advice?

Can't get photos or files right now, but will upload later if needed.

@JoergS5 I managed to fix it and am currently printing a calibration cube - will let you know how it goes but looking good so far...

Thanks so much for your help - it has been a long journey to get here!

@JoergS5 Afraid not - both of my heaters are now giving me faults (heating more slowly than expected). This happened yesterday too, but seemed to be fixed after I ran M303.

I am destined never to print with this board!

@JoergS5 said in Endstops not stopping motors:

@Harrynice you should also check the following chapter:
in https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3
"Endstop type S0 (active low switch) is no longer supported in M574 commands. Instead, use type S1 and invert the input by prefixing the pin name with '!'. Ex: M574 X1 S1 P"!xstop". Invert the input when using an NPN output inductive or capacitive sensor, or using a NO switch (not recommended, use a NC switch instead)."
You said you have active low endstops, so you may need the ! parameter.

I tried this again just to double check; once the '!' was added and the board rebooted, when i pressed home for any of the axes, z moved up as expected and then the other axes moved about 5mm or so in the wrong direction.

So, I removed the '!', rebooted and tried again and now all of the axes are homing properly!

I am REALLY confused now - that is the only change I made other than correcting the stop naming mistake you spotted earlier. I dont know what happened here but it looks (for the moment at least) like it is fixed!

Thank you so much for your help!

@JoergS5 said in Endstops not stopping motors:

@Harrynice What do you mean by stopping: it says immediately that endstops activated, or do you mean something else?

Sorry - not sure what you are referring to here...

@JoergS5 I do - have attached it to this post

config-override.g

@JoergS5 I have actually tried this; as soon as I add '!' to any of the stops, WiFi stops working...
