I have been upgrading my delta printer for a few months to print Peek and ultem, its nearly finished, just finalising the z probe although its manual. Just a few covers to print to make it pretty.
Specification:

• duet3d ethernet with paneldue
• 500w 240vac magnetic bed good for 150 degrees
• chimera water cooled, upgraded to copper heater blocks, high cartridge heaters and PT100
• manual mechanical z probe
• volume 300mm diameter x 280mm high
• heated enclosed chamber with extraction

Also will be investigating direct heating of the layers as they are printed to increase layer bonding.

How do i implement for the paneldue to display the chamber temperature?

Finally testing my high temperature delta printer, changed all pulley mounts to metal and calibrated machine. Looks a bit rough, but its functional, just waiting for sides to enclose the printer.

I must say that i am very impressed with the duet3d and paneldue, very easy to setup and calibrate, first prints were excellent.

Finally moved my delta to the fume cupboard to print PVDF. If the PVDF over temperatures 300 plus then it can give off Hydrogen Fluride, nasty gas.

Printing PVDF at 260 degrees, 60 degree bed on glass with 3dluc to aid adhesion, speed 15mm/s with 0.4mm retract. Good material to print, bonds very well between layers.

We are using the PVDF as it is chemically compatible with solvents we are using the prints for. Below are some pictures of the setup.

Update to upgrading my delta printer, the design has been refined following been added:

• IR strip lights to heat print to 80 degrees plus
• thermocouple on head to measure print/chamber temperature (yet to control via duet)
• front cover (still needs work to do)
• glass bed

Picture shows it printing with PEKK an electrochemical cell with 150 3mm hexagonal holes, prefect for a 3d printer

@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.

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?

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?
