@dc42 you saved the day again! It was a lose wire crimp that must have come undone over time!

@phaedrux I see no obvious damage on the pin or anywhere else for that matter.

I also ran a test to run the probing routine but pull the pin out manually beforehand it it did not work that way either

@phaedrux I am using a duex5, it is connected with the ribbon cable and running 3 of the Z motors.

When I do the boot up and it self tests it does not flash it stays with the LED on like everything is normal

If I pull out the pin it moves smoothly and the light turns off like it is operating correctly, when I put the pin back the light turns back on

the pin never deployed so damage to the pin seems unlikely through that route

I will disassemble it now and see what I can glean

@phaedrux

It is a BL touch I have been using, it was working just fine before this issue started.

I am using the deployment macros and test macros I am posting below

It was working fine and then I went to run a g32 and it didnt deploy the pin so I had to emergency stop it and it has not responded to commands since. I have power cycled it as well and same thing, but it does the self test and appears normal but is entirely unresponsive

Like the title says, my BL touch when the printer is turned on does its self test but then ignores all the commands I try to send to it after that. Anyone have any ideas?

@dc42 Ok I will change that over to right handed and see if that sorts everything out, the "back corner" on the height map shows it as low but the front in actually low and it sounds like the printer is just confused because of all the screwy coordinates

@dc42

Here is what I am talking about

EDIT: forgot to mention on the picture X0 Y0 Z0 is the back left corner but it shows on the back right corner fro the bed mesh

@dc42

My Main issue is that the G32 seems to level it backwards I guess, the front side of the bed is always too low and the back side of the bed is always too high, it is close enough to print stuff but say when I print a benchy, the skirt on the front is almost not wanting to stick and the skirt towards tho back of the printer is almost transpartent because its being squished so much.

I just tried to use G29 height map and it seems to be doing the same thing. I will draw a diagram to explain what I think it happening

@dc42 said in G32 not acting as expected:

Yes, the bug in 4-leadscrew levelling was fixed almost a year ago in firmware version 1.20.

I noticed reading about the M671 command that "For printers that print directly onto a desktop and have levelling feet, this command can be used to define the coordinates of the levelling feet, so that bed probing can be used to calculate and display the adjustments needed to the feet. In this case the displayed corrections must be reversed. For example, "0.2 turn down" means the bed needs to be lowered or the printer raised by 0.2 turn lower at that screw position."

My printer is a Hypercube that has the bed move down in +Z movement do I need to change anything due to that? The height map generated by a g29 seems to be upside down when I tried that so maybe that is the source of my issue?

@dc42

Ok good to know, the number has ALWAYS decreased when I did multiple G32 commands. I will give that F parameter a try and see what that does.

I am using firmware 2.02(RTOS) so It sounds like I am safe from math errors?
