@sungod3k I should also mention it can be very effective to add a few drops of brown or black tint to the resin.

Use a tint compatible with the resin you are using of course.

This allows you to adjust the metal colour to suit your needs. Like making Carbonite.

@mrehorstdmd, no problem, thank!

Great to see more Fusion360 users. It's a great tool. And great advice from @deckingman on how to design for the belts, and including all fasteners. I even include washers in my designs.

My general F360 advice (if you are not already doing these things).

Make sure all your sketches are fully constrained.

Use moving joints for moving parts. It's great for looking for things that will crash into each other.

Assemble your parts in the timeline in the same order as you'll assemble in real life. It's help expose places where things are hard to assemble.

This one is controversial, but I design most of my parts in separate files and link them into the main assembly. The good part is a simpler main assembly. The bad part is lack of ability to project features from existing parts. For parts that benefit from a lot of projections, I'll often design them in the main assembly file, then export to a stand-alone file when the design seems stable.

For flat parts that will get laser cut from sheet stock based on DXF files, I create a new sketch as the last part of the design that captures the whole part. This way, I get a DXF file where I don;t need to delete construction lines.

@dc42 Interesting, I will keep my eyes out for the changes in 3.5.

@Phaedrux OK thanks for all

@sungod3k It could pay well. AFAIK, Tom Sanladerer doesn't have a "proper job", and there are one or two others who's social media output is their main source of income. But it's a huge amount of effort - you have to do all the social media, not just YT. And there is a lot of competition out there nowadays so you'll need to find a "niche". I think your main problem will be finding people prepared to part with cash when the answers are all out their somewhere and for free.

.......................... My hot-end is a takoto and capable of these speeds.

I guess "pretty good quality" is a subjective thing - it's not the phrase I would use to describe the attached images. That aside, it would be interesting to see a video of the machine printing at 700mm/sec. But assuming for a moment that you can move the print head at such speeds, in order to attain that speed, you'll need very high accelerations - especially with the short moves on an object such as that toy boat. Whilst it is possible to accelerate a print head in 3D space at such accelerations, it is highly unlikely that the flow rate of the highly viscous molten filament being forced through a small orifice can be accelerated at the same rate as the print head. It's basic physics and no amount of tuning or tweaking is going to fix it.

@plasticfactory I would be interested in seeing if there are any differences in the consistency of the extrudate size compared to a standard nozzle I would also be interested to see if the improvements made to the nozzle since the previous tests had any effect on the surface finish of parts, or line consistency.

@achrn, thanks for your thoughts! I wasn't really looking forward to hoard yet another kind of filament as I have so much still to be used up but thought that maybe I should try and expand my world of filaments. With your comments, I think I will dig some more into PETG (and try something produced more recently)

@kjiwa the idler should be positioned so that the belt passes over it at the same distance from the vertical tower extrusion as it it in the carriage. That way, the belt sections above and below the carriage will be in line even when the carriage is right at the top of the tower.

@mrehorstdmd true <2mm would be massive. but that would also double the material use.
the prints im doing are just negative molds that get filled with plaster, so they just need to be stable enough to not deform under the weight of the plaster.

and yes ive also noticed that clean retractions with the bigger nozzles are hard. Specifically the de-retract. when the material rips of the from the rest of the material its just not a clean cut, so when the de-retract comes around its a bit messy. (and the z-hop doesnt help)

would be interesting to see if one could set a slicing behavior so that when the de-retract happens and the nozzle waits a tiny bit for the mess to be pressed into the below layer and only then continues its journey.

@o_lampe I like the hash printer gantry you build a lot. But I know that people who are looking for speed like the doubled torque of dual motors per axis, so each design has its place and its space.

Where is heater and thermistor?

No more oozing is quite nice. You close the nozzle instead of retracting filament. That allows using remote Bowden tube extruders.

I only hope it works smooth at different nozzle temps and in heated chambers...so many different material expansion-rates to deal with.

@dc42 yes, i contacted them also, they were a bit slow with the communication and 350 is a bit on the smaller side, but yes tractus is still on my shortlist.

@DIY-O-Sphere

Thanks for the hint of price range. I would like to go for a 500mm so my budget needs to be revised a bit if I read your hint right 😉

@alankilian said in LIDAR Bed Leveling:

@3Dreamer The sensor being discussed is not a LIDAR sensor, it's a LASER triangulation sensor, so it's nothing special technology-wise.

People use triangulation sensors for bed leveling all the time and it has it's good and bad points.

Hi alankilian,
you are right. I'll quote a paper in order to introduce readers to the differences:

3D ranging technologies generally fall into either position-based (triangulation) or time-based (LIDAR) approaches. Triangulation can provide much higher precision at close to mid-range but degrades quickly with the square of distance. LIDARs can provide reasonable precision over much longer distances but, unlike triangulation, they do not improve in capabilities at short range where precision and speed are critical for many applications such as autonomous rendezvous and docking, guidance and navigation, obstacle avoidance, and inspection.

So let's us speak about those technologies!

@alankilian
Thanks Alan,

This is not solved as it seems will have open a new thread there.

@gloomyandy said in Cura & RRF Power Supply (M80):

@cncmodeller Perhaps you could place your M80 in a start.g file, I think that gets run before any of the gcode in the file being printed....

For completeness this approach works great.

I also have a M81 S1 in my stop.g to shut off power after a print has been completed.

Thanks All,
Barry M
