Make sure to update the configuration and macro files to those compatible with RepRapFirmware 3.4.1

The instructions can be found on the modix support site, and you can download them here

@Phaedrux - SOLVED! I didn't even know there was a setting for that.

@john-sinclair203, I think your enclosure looks pretty good. Any chance you can share the files? Also did you need to bend or weld the acrylic to keep it more air tight for ABS.

@juku That depends on the diameter of the pulley. I specifically chose F608 bearings for pulleys in my printer because they meet the Gates recommended minimum of 9 teeth in contact with a smooth pulley surface. I get no print artifacts from the smooth pulleys.

@asif-istiak M82 seems to be a problem here - use M83 instead. Also why involving other axes that the one You want to move? G1 E1.0 F2.0 should be fine.

@bberger I am currently preparing iHSV servomotor mounts with 3:1 drive reduction for my corexy printer. I have designed and printed the mounts to directly replace the original motor mounts and will be installing and testing them in a week or two (waiting for Duet expansion board to arrive). I had previously tried driving the printer directly with the servomotors but found the resolution of their Hall effect encoders was insufficient for 3D printing. The new motor mounts use 20 and 60 tooth pulleys with F625 bearings and 5 mm shafts to do the reduction. Here is one of the two motor mounts:

The motors are good for 3000 rpm, so with 3:1 reduction driving a 20 tooth pulley in the corexy mechanism, they should be good for up to 666 mm/sec. That's faster than I would ever expect to print, but larger drive pulleys would allow higher speeds. The motors have plenty of "grunt" to move the mechanism- much more than the steppers.

@blt3dp

Will try that tomorrow, thank you.

@dougal1957 thank you!

Looks very promising!
I hope your airfield has a long start track and you don't have to start on grass? From the looks it'll need good speed before you can take off? On some of my faster planes I had to use a 3-blade propeller, because the ground clearance was too low for a decent bigger prop.
Can't wait for the lift off video

@zapta Thanks!

@deckingman thank you for the link the article is good as a start, and interesting in respect of other aspects like acetone.

I hoped someone has personal experience how many times recycling is possible.
Experience with factors like:

contamination decomposition at higher temperatures *) effects of the colors effects of water content how to separate plastics by spectroscopy, density are other thermoplastics better suited

*) is it 0% if staying at normal melting temperature, or is it e.g. 5%, which limits the number of cycles it can be recycled?

@tenaja I perused a few of the reviews on all3dp.com and it was helpful, thank you!

@dc42 typical eBay description flamboyance, lol.

"This is a once in a generation chance to get this amazing printer at a fraction of the new price and already built and configured."

I brought mine secondhand for a fraction of the retail price.

Pretty sure I saw something like this at MRRF...

Yup here it is.

@vladimir_u said in Future development?:

@infiniteloop Unfortunately, socialism has lost to capitalism...probably with our help.

Large scale socialism is doomed to get corrupt and fail.

Small scale socialism is the norm for thousands of years. Every household is a socialist unit, "From each according to ability; to each according to need".

And don´t forget the lightweight PLA.
