configuring Dual Z w/ Dual Z endstops....
-
ive read the document, though i dont see alot of information about dual Z endstops
https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors
also theres also this so im still a bit confused about the right / wrong way to go about this
https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches/182 Z screws connected to Y and E1 .. I used Y because my Y is serial Dual steppers also... so i put them on the Z plug
right now my config.g looks like
; Drives
M569 P0 S0 ; physical drive 0 goes forwards
M569 P2 S1 ; physical drive 2 goes forwards
M569 P1 S1 ; physical drive 1 goes forwards
M569 P3 S0 ; physical drive 3 goes forwards
M569 P4 S0 ; physical drive 4 goes forwards
M584 X0 Y2 Z1:4 E3 ; set drive mapping
M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z800.00 E420.00 ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E250.00 ; set accelerations (mm/s^2)
M906 X800 Y800 Z800 E800 I80 ; set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minima
M208 X350 Y350 Z850 S0 ; set axis maxima; Endstops
M574 X1 Y1 Z1 S0 ; set active low and disabled endstops -
for dual endstop you should upgrade to rrf3
see
https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3 -
Your config.g file indicates that you are using RepRapFirmware 2, so the second link in your post is applicable. However, if you are ready to upgrade to RepRapFirmware 3 then it supports multiple axis endstop switches much more directly.

@Veti RR3 runs on Duet 2 ? I thought it required a raspberrypi 3 ? or is that just for a Duet 3 ? and how does one convert working configs ??
-
@dc42 so... Thanks foir the input, use the second link if i stay on RR2, use the first if i decide to go to RR3.... what scares me is the config changes required to get to 3 from 2 when i almost have 2 completely configured properly.
and RR config doesnt seem to work for RR3. -

yes

no, not even on the duet 3.

why not?

@Veti i tried it, wouldnt let me download anything.

works for me. did you forget to add the io mapping?
-
@Veti must have been cashed in the browser.... ok went through it again i see 3 issues..... doesnt appear to let me map E1 to Z2 ... manual edit i guess, hrmm hows the second Z stop get configured LOL
kill me now... ok ok putting on the patience hat.... and second BLtouch is blanked out ... i generated what i could for V3 lemme start manually editing to match what i had for v2 ...... -
@dingo007 said in configuring Dual Z w/ Dual Z endstops....:
and second BLtouch is blanked out
you need to assign PWM Control Channel (BLTouch only) in io mapping
dual z stop is explained here

@Veti wow this config is really confusing now.....

@dingo007 said in configuring Dual Z w/ Dual Z endstops....:
rr3 config (makes no sense) (M584 X0 Y2 Z1 E3:4 should be M584 X0 Y2 Z1:4 E3 )
yes change it. thats the manual change that you did.

@dingo007 said in configuring Dual Z w/ Dual Z endstops....:
M574 Z1 S0 P"ystop" ; configure active-low endstop for low end on Z via pin ystop
now add your second stop like this
M574 Z1 S0 P"ystop+e0stop" ; configure active-low endstop for low end on Z via pin ystop -
@Veti
And below where it states, makes completely no sense to my brain, can someone explain ?
You must use the M671 command to define the X and Y coordinates of the leadscrews
where my left and right Z screws are at 225 to the bed which is centered of the 450x450 bedM671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis
M208 X-5:205 Y0:200 ; X carriage moves from -5 to 205, Y bed goes from 0 to 200 -
@Veti said in configuring Dual Z w/ Dual Z endstops....:
M574 Z1 S0 P"ystop+e0stop" ; configure active-low endstop for low end on Z via pin ystop
Im using Y and E1 so.....
M574 Z1 S0 P"ystop+e1stop" ; configure active-low endstop for low end on Z via pin ystop -
@dingo007 i guess its..... ???
M671 X0:250 Y0:250 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis
M208 X0:250 Y0:250 ; X carriage moves from 0 to 250, Y carraige goes from 0 to 250 -
@dingo007 said in configuring Dual Z w/ Dual Z endstops....:
M671 X0:250 Y0:250 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis
what are you trying to do now? dual z endstop or independent leveling?
thats only needed for the second one. -
