Does anybody know which directory on the Raspberry pi the config files are stored for the duet 3, i want to copy the config.g?

@DaBit they are holding up but i am changing the design to move the slideways and belts to the outside of the machine. It will look ugly and fit for function long term i will redesign, this will allow 200 plus temperatures in the chamber.

The latest upgrade to my high temperature delta print, fully insulated with aluminium backed rock wool. Also i am printing on glass using vision miners nano adhesive to print peek and ultem, its good stuff but not cheap, i would certainly recommend it.

My delta reaches 450 degrees no problem with an e3d online hotend, not tried 500 yet, but there are no plastics that i am aware of that need that temperature.

@tekkydave cheers that works

@dc42 i tried M950 S7 c"io7.out" and then M280 S7 S80 and it did not work and just an error: duplicate S parameter but i cannot see another S7 in the config.g

I am struggling to figure the code to put in the config.g to control a RC servo connected to IO7 on a Duet 3, please can somebody help me?

@DaBit IR maybe a good for your machine as you are only heating up the part, but your bed moves unlike a delta printer. My machine has a thermocouple on the end effector with a black heatshrink sheath to measure the temperature close to where you are printing and i have been monitoring the sides an they get up to a max of 40 degrees with chamber at 110 degrees. If you go down this route try to eliminate black or dark colours, i have changed most to reflect the IR.

@DaBit i use a water cooled chimera with a pt100 and the high temperature heater, copper heater block and copper plate nozzle available from e3d online. The chamber/print is heated by ir strip heaters which are idea for the delta printer as the bed is fixed.

For ultem 1010 really need a chamber of 110 plus and the cost although for the filament is much cheaper than printing PEEK. Higher the chamber temperature helps layer bonding, stops warping and reduces the thermal stresses in the printed part, although you can anneal it after printing.

What type of printer do you have? Do you have a picture of it? If you are interested in the ir strip setup i post details and suppliers etc.

@dc42 said in Z height probe before print starts:

G1 X0 Y0 Z5 F6000

so is the command G30 S-3 to set the z height before the print?

Picture below of a test print in Ultem 9085. Its printed on kapton tape with a bed temperature of 150 degrees, hotend 395 degrees and chamber at 115 degrees. The printer has also printed PEEK and PEKK, although PEEK is difficult to stick the bed.

Next i am designing a 200 degree plus vacuum heated bed for plastic films to be printed allowing greater flexible to bed material changes.

Please can somebody tell the command to measure and set the z height with the z probe before the prints starts, i only want to measure the center (x0,y0) so i can add the command in the start gcode of the print.

I am having problems with the config since changing to firmware3, i looked in the wiki on z probe and the only mention of the latest firmware is in the BLTouch section, is this relevant for all z probes or just the BLTouch?

firmware changes
M558 P8 C"^zprobe.in" F100 H15
is this correct, its wired to the z probe (duet2) and its a switch?

Thanks in advance for any help

@droftarts i have figured out the problem the 5v supply to pi is split one to the touch screen and the other the board, so if i disconnect the power to the pi and power the duet it works with top jumpers connected. Thanks for your help.

Andrew

@droftarts the top two, so internal 5v En and 5v->SBC

@jay_s_uk which jumpers please, just followed the instructions on the wiki.

@droftarts i have read through the notes and it does not say how to choose the booting for duet3 or pi. I have a problem that if the pi is connected to the duet3 and duet3 is powered then the pi does not boot up. I have to disconnect the power to the duet3 and power up pi to get it working.

I read somewhere that either the duet3 or pi will boot the other up on power up, but i cannot find where the instructions, can anybody help please?

@Danal Sorry ignore my post its working, me being a bit thick

Duet 3 Pi not rebooting after a change on the config.g configured to my delta. Does the Duet 3 require the thermcouple and PT100 slave boards adding if configured in the config.g, is this stopping the PI displaying anything?
