configuring Dual Z w/ Dual Z endstops....

Veti

for dual endstop you should upgrade to rrf3

see

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 ??

dingo007

@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.

and how does one convert working configs ??

why not?

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

works for me. did you forget to add the io mapping?

dingo007

@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 ......

Veti

@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.....

yes change it. thats the manual change that you did.

Veti

@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

dingo007

@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 bed

M671 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

dingo007

@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

@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.
