Duex5 drive and endstop mapping

Phaedrux

How bout this one? M98 P"config.g" That might give us some syntax errors from your config.g.

3.3RC3

Firmware 3.3 final is available now, so good idea to update.

Upload this zip file to the system tab in DWC.

Y: no endstop

Can you repost your current config.g after any changes you've made? Looks like the Y endstop config isn't correct.

@phaedrux How do I get the M98 P"config.g" information?

resh

@phaedrux Ok I've got it homing now after the update but I've got a new problem. When I press HomeY on the panel due the gantry moves away from endstops. I thought I could just switch the S0 in the mapping of P5,P6 but it's not switching. Do I have to wire it backwards? The steppers don't seem to be fighting each other.

The Y steppers are facing away from each other. I switched P5 S0 to be opposite P6 S1 and they fight when I press homeY.

Update:

When I send M564 S0 H0

X moves correctly
Y moves correctly
Z moves correctly (a negative number should move bed downwards?)

~~I can home X and Y individually via paneldue with no problems.~~ I can home X individually and move it afterwords via paneldue. Homeing Y individually works but after it's homed I can't move it individually.

When I press home all or try and home Z individually all hell breaks loose. It sounds like all the steppers are fighting each other but individually they seem correct. I'm making headway, thanks for all the help.

EDIT: When I home Z the Y axis goes all the way to the back, hits the endstops and tries to continue moving backwards (crashing). It seems like it doesn't recognize endstops when Z is homed.

@phaedrux How do I get the M98 P"config.g" information?

You send M98 P"config.g" as a command in the gcode console and it will execute your config.g as a macro. Any syntax errors will get reported to the console.

@resh said in Duex5 drive and endstop mapping:

Z moves correctly (a negative number should move bed downwards?)

Negative Z should bring the nozzle and bed closer together. Positive moves them farther apart.

Let's take a step back for a second and get some things sorted out.

First you need to set your mind to the correct coordinate system and everything else will flow from there.

When looking at the printer from the front:
-X moves to the left, +X moves to the right
-Y moves to the front, +Y moves to the back

That's just the way it is.

The endstop location defined in M574 will follow this. If the endstop is at the low end of travel or high end of travel. If it's at the low end it will be X1 or Y1, if it's at the high end of travel, it's X2 or Y2.

That's just the way it is.

The homing direction is set in the homing macros. If the endstop is at the low end of travel, the homing move needs to be negative. If it's at the high end, the homing move needs to be positive.

That's just the way it is.

Now with all those things set in stone, the motor direction of rotation will need to be changed to allow the rest to be true. So if a -X move actually makes it move to the right, then you need to change the direction of rotation on X. Same for Y and Z axis.

Once that rotation direction is correct everything should fall into place provided the other details of endstop position and homing move direction are correct from the start.

Phaedrux

M574 X2 S1 P"!xstop"                           ; configure active-high endstop for high end on X via pin !xstop
M574 Y1 S1 P"!ystop+!e0stop"                           ; configure active-high endstop for high end on Y via pin !ystop
M574 Z2 S2                                     ; configure Z-probe endstop for high end on Z

So your endstop definition says that X is at the high end of travel, so the homing move should be positive.

It says Y is at the low end so the Y homing direction should be negative, but your homeall has a positive Y move.

It says your Z axis is at the high end of travel, so when the bed and nozzle are farthest away.

So where are the endstops actually located? That's the first question.

@phaedrux Thank you for all the thought out responses. My Y endstop is at the high end. I changed to M574 Y2 S1 and everything is working properly now. I also changed the Z direction. Thanks again

Phaedrux

Glad you got it sorted out.
