thanks for the suggesting in 2. I will impliment a square move instead of a linear move. I assume this would also be useful to avoid majority of the half printed workpiece by moving around its perimeter.
I don't have a call to lock and unlock because I am using magnets.

(not connected to the duet2. not sure how i would do it).
You can't. Don't connect it. It is really a stand-alone PI, just happens to be built with the Duet image as a start.
i followed this tutorial to set up duetpi on raspberry pi 3. took out the card and put it into the raspberry pi. powered it up, all i get is an endless list of EXT4-fs error lines after line. been doing this for the past 2 hours. not sure if I did something wrong?
Followed the Duet "etch" tutorial? And edited wpasupplicant.conf? And did NOT format when windows complained about the card after etching?
That last bit is the most important. The card is partitioned, with a windows readable "boot" partition and a much larger Linux partition. Windows tries to assign a drive letter to that Linux partition, balks, and asks to format it. Which you must always decline,
EXT4-fs is the file system that windows doesn't like, and asks to format. That certainly seems to relate to those error messages.
Yup. I followed the tutorial on duet exactly. Only thing was inside the boot partition, it already contained a wpasupplicant.conf file. I Openned itnin notepad and editted it with my ssid and PW. Pulled the card out and popped it in to the rpi. Then powered it up. Will try again tonight

you won't believe this. I used my other laptop running windows 8, win32diskimager to load the duetpi image. and that worked. i have no idea why using balena etcher on win 10 doesn't work.
these are what i came up with. it uses a plate of magnets in alternating polarities turning the plate 30 degrees in either direction will couple or decouple the tool from the x carriage. i was inspired by the jubilee and the way it is assembled is based on it's design. however, instead of having a frame mounted motor, it uses a N22 gearbox motor driven by a servo module or a mini stepper motor. still a concept at this point.
since it would require hardware either with neopixel or dotstar on the duet2 board. which way would be the easier route? is there a tutorial page with hardware to purchase and downloadable code to compile into arduino?
@JoergS5 i have the duex5. which pin would i use? i am already using all 10 motor ports
would it be possible to use the pwm fan output to control a stepper motor with something like a L298N module? the thing is, i do not plan to use arduino to control it. i was hoping to send the PWM signal from the pwn output to the module to have position control of the stepper motor. reason why i want to do this is because i can find stepper motors with a much smaller physical size with all metal gears compared to a RC servo.
or would a DC servo motor be just as accurate?
I found some N20 geared DC motor that I plan on using as a switch. based on this link, it mentioned the need for a flyback diode: https://forum.duet3d.com/topic/6415/bi-directional-dc-motor-control-without-h-bridge/1
I don't want to use the PWM output or the heater channels because they are used for something else. the only output channels I can think of that remains are the fan output to perform this function.
thank you.
thank you. you have solved one of the biggest mystery for me. i am trying to design an electromagnet tool change system for a corexy and one problem i have is if for whatever reason i lose power, the extruder will just fall on the build plate since it isn't mounted on rods like on a cartesian with a moving Y.
working on my own tool changer. does using PWN1 require disabling the heater channels?
thanks for your help. i am not familiar with conditions and its syntax. this totally helps. does duet website have any information on other conditional commands that can be used ( not particular to this OP)?
i have a duex5 and the heater in question is heater 2 (which is the first heater on the board). it is also assigned to tool T0.
Would this be correct?

hi there,
i have set up my machine to home Z after heating up extruder to 150C. However, sometimes i need to change filament or stop a failed print and start over. i generally home Z again because i need to rip off whatever failed which can move the bed. however, the hotend is at a higher temp than 150C and it would wait until it falls to 150c before it starts to home. is there any ways to set it up so that it will home at 150C or greater?
