Hi,
I am looking to use duel z motors in parallel mode, other than buying a spliter from aliexpress, would there be a way of doing this directly on the duet i.e. how would i go about wiring z axis for parallel mode rather than serial mode.
Would this improve bed levelling in any way i.e. stop the motors from going out of sync.
Kind Regards
Hi,
Does the probing and ABL experience get better with using the endstop to set 0 and inductive probe to set mesh for abl...
or does it add no value to using the z probe by its self...
Please help or refer me to other user cases of this setup
whats better probe only or probe and endstop.
if the probe and endstop yeilds better result for bed levelling and z offset
please advise and share experiences
Hi,
I've got a silicone heated bed that has a 12v 240w sticker on it
Would connecting this to the device below allow me to connect the heater to the 24v driven duet wifi:
I wouldn't want to use another power supply to run it.
Hi,
whats a better version, or more stable/ reliable version of ABL
Or what are difference if any
which firmware did you have a better experience on
how would one go about installing Marlin 2.0 on the duet hardware
@deckingman
Thanks for the response, the extruder im using is a fake bondtech style
Would you recomend me increase the jerk speeds since when the printer shifts it is very rough...or would that be fine
I want that kind of move to be a bit more smooth so would i need increase the jerk or decrease it
Speeds in Marlin for the same hardware are:
#define DEFAULT_XJERK 7.5
#define DEFAULT_YJERK 7.5
#define DEFAULT_ZJERK 0.2
#define DEFAULT_EJERK 0.10
#define DEFAULT_ACCELERATION 500
#define DEFAULT_RETRACT_ACCELERATION 500
#define DEFAULT_TRAVEL_ACCELERATION 50
These speeds in marlin were slow but perfect
My current speeds for duet are:
M566 X650 Y650 Z12 E120:120 ; Set maximum instantaneous speed changes (mm/min)
M203 X6000 Y6000 Z100 E1200:1200 ; Set maximum speeds (mm/min)
M201 X2000 Y2000 Z1250 E500:500 ; Set accelerations (mm/s^2)
in duet im really just worried about the jerk doesn't seem smooth
As per the documentation speeds in marlin are in mm/s whilst speeds in duet are mm/min
So would these new values make sense:
M566 X1000 Y1000 Z12 E120:120 ; Set maximum instantaneous speed changes (mm/min)
M203 X30000 Y30000 Z150 E1200:1200 ; Set maximum speeds (mm/min)
M201 X3000 Y3000 Z1250 E500:500 ; Set accelerations (mm/s^2)*
I am using standard belts and MGN12H rails
Please Advise
Hi,
I have a spare 12v silicone heated bed, what modifications would I need to make it work on a 24v power supply?
.Buck converter
.Mosfet
.Direct connection with issues( please explain any potential issues)...
Please Help
I think for now in relation to my other post I am likely to use basic painters tape with ABS juice, as I have seen a youtube video that shows it being effective for pla/abs/petg... whos to complain.
In fact after having an even better squish on a buildtak like surface, the print is sticking to well
when viewing the heightmap when i see red do i need to loosen or titan the set screw, and how about when I see blue do i tighten or loosen the screws.
Manage to sort out the height map and make it as even as possible please look and judge my handy work.
So I've done further tweaking, and i might be onto something...
I ran M48.g as describe by this post: M48
M292
G32 bed probe heights: -0.024 -0.013 -0.021 -0.012 -0.025 -0.020 -0.025 -0.030 -0.022 -0.041, mean -0.023, deviation from mean 0.008
Before I did this i was tweaking my bed according to the heightmap.csv
01:25:46
G29 S0
9 points probed, min error -0.048, max error 0.136, mean 0.029, deviation 0.054
Height map saved to file heightmap.csv This was done when heated at PLA Temps
Its looks like the following:

When cold it looks like the following:

0.154, 0.051, 0.014
0.267, 0.101, 0.048
The question is, what do you reckon, do you see these tweaks improving my first layer...?
