Triple Z Ballscrew G32 Leveling Wrong Direction

@jordan_miller41 said in Triple Z Ballscrew G32 Leveling Wrong Direction:

How can I switch my Y-Axis direction to be Y0 at the front?

M208 X0:100 Y0:100 Z0:100 ; a imaginary printer X=0 to 100 Y=0 to 100 Z=0 to 100

M574 Y1 S1 P"ystop"       ; this would configure an active-high endstop for low end of Y

M574 Y2 S1 P"ystop"       ; this would configure an active-high endstop for high end of Y

The following command would move in the positive direction on Y until it moved 199 mm or the endstop is triggered.
G91
G1 H1 Y199

The following command would move in the negative direction on Y until it moved 199 mm or the endstop is triggered
G91
G1 H1 Y-199

In either case when the endstop is triggered the Y position is set to according to the settings in M208 and M574

If the M574 specifies the endstop is at the low end of Y then the Y position is set to Y min as specified in M208.

If the M574 specifies the endstop is at the high end of Y then the Y position is set to Y max as specified in M208.

These settings much be "in sync". Things are not going to work as expected if:

the endstop is located near Y max but the M574 says it is at Y min.
the endstop is located near Y min but the M574 says it is at Y max.

Also the endstop may not actually trigger at exactly Y min or Y max but the Y position is set by the G1 H1 command as if it is.

When this is the case you can use a G1 and/or G92 commands to get the actual Y position to match the firmware Y position.

My guess is you have got M208 and/or M574 wrong.

Of course you have to have the M569 command set so the axis moves in the proper direction for + or - moves.

It gets a little more complicated with coreXY. When in doubt, use this motor direction test.

@jordan_miller41 can you share your entire config.g file?

Where are your endstops located?

End stops are located left side for X and Front Left for Y. I do remember having the Y setup to where the homing is at the maximum and I think it was because it went the wrong way initially, I could be remembering wrong as this was 6+ months ago when I first started.

@fcwilt Ok.... I followed @Phaedrux 's article he tagged and have my motors flipped, when I move with the G92 command I get my proper +Y to the back of the printer and +X to the right of the printer. Origin being at the front left corner of the build plate.

The next issue I had to deal with was flipping my pins for X&Y endstops, I have X working as it should, but no matter what I change, the Y-axis goes to the back of the printer (Ymax) and not to the front. I changed the M574 Y1 S1 and it still wants to move to the Ymax. So I am kind of at a loss here. Not sure what is happening, I am sure it is something simple I am missing.

@jordan_miller41 the config.g just tells the machine where the endstops are. You want to edit the homing files (homey.g and homell.g in your case) to change what it does when you click the home buttons

Jordan_Miller41

@engikeneer that would make sense now wouldn't it. Thank you for pointing out my blindspot.

@fcwilt said in Triple Z Ballscrew G32 Leveling Wrong Direction:

@jordan_miller41

Your M584 has this: M584 X0 Y1 Z3:4:5 E4.

Let's assume that is correct - for now.

Then in the M671 the first X/Y values must refer to Z3.

Likewise the second X/Y values must refer to Z4 and the third X/Y values must refer to Z5.

And, of course, each stepper in Z3:4:5 must actually be connected to the stepper that is near those X/Y values.

And the G30 X/Y values in bed.g don't really seem to match up well with the values in M671.

If things are not in sync the process can make the bed less level.

Now back to your M584:

You have Z4 and E4 - one of them must be wrong.

Frederick

Can you explain to me what the E4 vs Z4 thing you are talking about is? Is E4 even needed, I am kinda confused.

Your board has driver connections for 5 steppers.

In your M569 they are P0.0 to P0.4.

Just FYI, since the 0. prefix is the default you can use the short form of P0 to P4.

The first M584 you posted had X0 Y1 Z3:4:5 E4 which says:
X is connected to driver 0
Y is connected to driver 1
Z is connected to drivers 3, 4, 5 (meaning 3 steppers for auto leveling)
E is connected to drive 4.

So the Z seemed wrong since you didn't seem to have 6 drivers.

The E seemed wrong since the Z was already specified as using drive 4 so E could not also use drive 4.

Your last M584 has X0.0 Y0.1 Z0.2 C0.2 E0.3:0.4 or in the simplified form X0 Y1 Z2 C2 E3:4

I have no idea what the point of C0.2 is.

The E makes sense if you have two extruders.

So what is C?

And do you have two extruders?

Thanks.

@fcwilt Ok, that's kind of what I was thinking. Here is my layout. Btw I have Duet 3 6ch MB and Duet 3Ch daughterboard with SBC Raspi 4.

I also am using E3D's toolchanger, therefore the C-Axis.

Mainboard:
Drive 0: X
Drive 1: Y
Drive 2,3,4: Triple Z
Drive 5: C axis (toolchanger)

Expansion Board:
1.Drive 0: E0
1.Drive1: E1

Does this clear things up? I think we were getting some wires crossed haha.

So would this be correct to correctly map what I have above?
