Mini5 to 1LC to smart effector wiring and control

@arnold_r_clark
well I was working from the instructions and config tool and both used the control and mod pins - found a post from DC42 referencing the need for the second pin if you wanted to adjust sensitivity but should work without it.
either way changing my M558 to only reference 20.io0.in still gives the same error though it does add "z probe" to the dasboard but not responding
I have had plenty of head crashes in the past so when it comes to the Z probe I make sure it works before commanding any movement.
the only references I have found to index is with multiple probes and there is an optional K parameter to M558 but tried adding K1 with no change.
without any references to what this error means I am struggling
-
@opentoideas your M558 line should be this
M558 P8 R0.4 C"20.io0.in+io0.out" H5 F1200 T6000note the removal of the 20. in the middle.
Can you post your full config and the actual wording on the error? -
@jay_s_uk @Arnold_R_Clark
must have been syntax as I thought mine and Arnold were the same but a copy and paste and it now works - not sure where the difference was but its running.
Jay I tried your M558 back to the error :
Error: G31: Invalid Z probe index
flip side without the second pin reference when I try to reduce the sensitivity....
M672 S105:020:235
Error: M672: Programming remote Z probes not supportedso with a single pin reference it works but the contact is far to hard and I seem unable to reduce the sensitivity

@opentoideas my guess is that theres something strange when using the toolboard to connect to the smart effector.
I don't see why it wouldn't work.
Maybe @dc42 can comment? -
@jay_s_uk yes I suspect the same. It looks like the sensitivity isn't lost on power off so worst case I will just have to make up a lead to directly connect the effector to the mini5 to adjust it.
at the moment it takes a huge force to trigger so unless I have done something wrong in assembly then it needs to be a lot more sensitive.
-
Its also possible my fan shroud is providing too much contact and support to the hotend heatsink. I am thinking this could dramaticly reduce sensitivity.
Tomorrow's job then will be to strip it down and fettle the fan mounting around the heatsink so its close but not touching. See if that helps.
-
@opentoideas programming the sensitivity of the Smart Effector from a tool board is not supported yet.

@dc42 thank you, I will modify the fan shroud first and only adjust the sensitivity as a last resort.
-
so I modified the mount to give clearance but it didnt make a huge difference.
reduced the sensitivity to 25 and that seems to have done the trick. everything now working so I have another question relating specifically to a delta....
@jay_s_uk since the tower endstops are at the top how does homing the towers relate to probing the bed?
what I mean is that in gonfig.g I define the height of the print area and when the homing command is run all towers move to the top and Z is set to the height given in the config.g
does this overwrite the Z=0 that was determined by probe results?
my normal routine on powering on the printer would be home all, delta calibration followed by mesh levelling then a home all to put the carriage to the top but wont that negate the probed height?
I am thinking that rather than a home all at the end I should just use a move command to move the carriage up and centre it?
definitely heading into the over thinking it category now but I am new to deltas and some things are not intuitive.
-
@opentoideas once you run G32, a new overall height is calculated and can be seen in M665.
That can then be saved using M500 so it appears in config-override.g and reloaded at the end of your config using M501 -
@jay_s_uk ahh the missing link. Thank you so much. I thought I must be missing something.
Running a few cycles of levelling to check consistency and probing trigger point then I will get the first print going and see how it goes.
Thanks again for your patience and help

@opentoideas good luck!

@opentoideas said in Mini5 to 1LC to smart effector wiring and control:

Yes. That's why I recommend that on a delta, after homing and before printing you run G32, and then don't home again. You can also run G29 after G32 if you want to.

@dc42 @jay_s_uk so I have added a M500 to the end of bed.g
my thinking is that now having homed and levelled the settings are now stored and a home all command will now accurately home based on the probed height?
just running a final mesh with everything hot to see if there is much variation from cold and soon printing again

@opentoideas heres my bed routine

Then the heightmap can be loaded and the print started -
@jay_s_uk interesting. Gave it a go and had to increace the tollerance to 0.03 as my average was 0.025 to 0.032
spoke too soon..... now holding closer to 0.1
I suspect that this is telling me I need to improve the mechanical accuracy of the machine and unless the tramming of the legs has been bumped out I suspect that my printed adapter for the arms is the most likely culprit.
- arm spacing looks bad so tomorrow will try to sort that out with shims as they are all under.
This will be solved soon once the linear rails arrive and I can swap to the magball mounts on the smart effector but its something to fettle while I wait
-
@opentoideas yea, 0.1 is pretty poor.
Magballs and the smart effector PCB carriages should solve some of that. Hopefully there's no other slop in the system -
@jay_s_uk before the change I was pretty consistent at about 0.014
It seems likely the printed caraige adapter is the culpret so I will start with getting the arms parallel hopefully that removes a good chunk of the error
-
Well I was wrong. while the arm spacing was out they were within 0.5mm of each other but what I did discover was that one of my arms had a very sloppy ball joint.
it must have been one of the 2 spares that I had and got swapped in by mistake when I swapped things around.
changed it and back to a deviation of 0.014 on the first run

@dc42 I am having a problem with my fans when printing
; Fans M950 F0 C"20.out1" Q500 ; create fan0 on pin 20.out1 and set its frequency part cooling M106 P0 S1 H-1 ; set fan0 value. Thermostatic control is turned off M950 F1 C"20.out2" Q500 ; create fan 1 on pin 20.out2 and set its frequency hotend M106 P1 S1 H1 T45 ; set fan1 value. Thermostatic control is turned on M950 F2 C"out5" Q500 ; create fan 2 on pin out5 and set its frequency Duet cooling M106 P2 S1 H-1 ; set fan 2 value. Thermostatic control is turned off M950 F3 C"out6" Q500 ; create fan 3 on pin out6 and set its frequency PSU cooling M106 P3 S1 H2 T30 ; set fan 3 value. Thermostatic control is turned onthis is as per the documentation with part cooling on out1 and hotend on out2 on the 1lC
when I print the hotend fan gets shutdown which I believe relates to the slicer using the deprecated M107. I found a thread suggesting part cooling set to fan0 and hotend to fan1 and so I swapped them above but still get the same result with the hotend fan shutting off at start of print.
is this a quirk of the 1lC or have I made a daft error?
