I'd have just cut the tops and bottoms off of 30 gallon paint drums, stacked a few and sealed em up! Cool project, I'll try to follow along!by clearlynotstefan - Delta Machines
Assuming your tube needs to reach the top (during homing moves), the shortest distance is usually a hair above 50% between the bed and the endstops (the extra few percent are the bend required during homing), at the top requires a bowden length of 100% of the machine to reach the bottom, at the bottom requires 100 to reach the top during homing, half is the play. But seriously, for $5 worth of hoby clearlynotstefan - Delta Machines
Go with Haydn's rods. You can order them on ultibots, they're fairly priced and outstanding.by clearlynotstefan - Delta Machines
THe thing is, with a flying extruder, you're already adding that weight to the carrier anyway. and worse, you're suspending it from elastic which is going to bounce it around and exacerbate the effect it has, How much weight can you be adding by adding arms so it gets pushed where it needs to be instead of dangling in the air?by clearlynotstefan - Delta Machines
Yeah I'm sure the double delta idea would work well, but its a lot of work and money to fix a problem that doesn't even cause problems on my prints lol, more just a theoretical thing I think every time I watch my extruder swing around on elastic doing infill and think "that can't be good". It's better than a software option to keep it within a set distance, with my firmware I could set both motorby clearlynotstefan - Delta Machines
So I pitched this crazy idea in the duet subforum because the original iteration needed firmware to play nice, but it lead me to consider a simpler form that should work pretty well too I think. I'm a big fan of flying extruders on taller deltas to avoid the retraction issues that follow a long bowden tube, my current set up has my extruder suspended from the carriages by balloon animal balloonsby clearlynotstefan - Delta Machines
Please do, I'd love to understand what you're driving at because my bad understanding of your plan doesn't seem effective, I'm sure there's more to it! Lemme know how it goes if you try it!by clearlynotstefan - Duet
I'm not following how a second set of carriages holding the the extruder via fishing line is going to make the extruder follow the effector I guess. Also I don't think mass on the carriages is a problem at all, mass at the effector is bad news but I don't think steppers are struggling for torque moving the carriages and the effector, the problem is just where the weight is in my opinion.

Are you not familiar with flying extruders? I'm sorry I don't follow your idea really, might be misunderstanding it. I'm currently using a flying extruder that isn't all that different from yours. I don't really get the distinction between your idea and a typical flying extruder other than having a second set of motors and belts apparently. Maybe I'm misunderstanding, the problem with a typical fby clearlynotstefan - Duet
Thoughts on my idea? (Besides its obviously overkill) Anything I'm missing?by clearlynotstefan - Duet
Is it possible with a duet wifi to have two motors mirror each other? IE on a delta have 2 motors on each tower doing the exact same thing? I just came up with a crazy idea. Basically I wanna try making a decoupled extruder holder. Essentially I'd like to mount a second set of steppers facing out from the towers with carriages that ride along the backside (the outside) of the linear rail/extrudeiby clearlynotstefan - Duet
Just placed my order. Very excited. Is the piezo somehow integrated into the pcb? or do we sandwich one in between the bolt and heatsink? Do you have an stl for those carriages, or are they included with an order (The plastic parts, not the pcb)by clearlynotstefan - Delta Machines
Yes! I've been waiting to see how this turned out. I don't yet see it on Filastruder for US distribution. Will Tim be getting any in for us yanks? On your sales site, I was going through the checkout process to see what a final cost as configured would look like. I'm getting a mandatory field to purchase an e3d v6, but I already own a few and don't intend on purchasing another... The text impliesby clearlynotstefan - Delta Machines
Multiple nozzles create their own problems though, but I agree it's got use for nozzle diameter. However if you end up needing a prime tower between diameter changes, you'll lose much of the time you save, plus the oozing problems etc scares me. Shouldn't be that crazy to make a nozzle that twists to shrink the exit diameter, right?by clearlynotstefan - General
So I was considering the benefits and limitations of FDM/SLA etc. SLA trounces FDM in resolution but lacks in strength and is expensive in consumables (resin etc). I rather like the benefits of FDM though. I started thinking of ways of making FDM better. Resolution is improved with smaller nozzle diameters and layer heights, but that makes print speed unreasonably slow. I think as long as we're sby clearlynotstefan - Duet

Rather than using a typical resistance coil type heater for my bed, I'm considering something a bit more active, such as a ceramic space heater or modified heat gun pointing into the chamber. I'd basically leave the switch on, and splice and the power cord to an ssr to be controlled by the duet. My concern now is how adjustable are the pid/bangbang settings?

My build and bed-mounting solution is stable enough that I suspect I don't need to be calibrating for each print. How do I go about storing the results of a S8 calibration though? I can update delta radius, height, etc but how to store endstop offsets and X (deg) Y(deg) etc?by clearlynotstefan - Duet

I'm working on a part cooling fan and wanted to know which fans I'm looking for. I ordered these:2pack 50mm x 15mm 5015 12V Dual Ball Bearing DC Brushless Cooling Blower Fan BB5015H12 with 2 Pin Terminal UL TUV And they work great but don't respond to pwm at all,, they're binary at 100% or completely off.

Great, I'm not an electrical engineer so a few basic questions if you have a moment. Let's say it's a blown via. Can I create a bridge to replace it? I'd be afraid of bypassing all the stuff in between if I just jumped the solder pad to VIN. Next, if it is the regulator itself, or if the via can't be bridged, would getting a 5V power supply and setting the jumper pins accordingly allow me to compby clearlynotstefan - Duet

So I did some work on my effector and was changing my part cooling setup. I wired two 30 mm fans in series to always on fan one. Long story short my splice wrap came undone connecting hot to ground and melting the connector to fan 1, throwing a few sparks and shutting the machine down. Machine would only give me a blue led after that and I assume she was gone forever. But then a miracle happened,by clearlynotstefan - Duet
How bad can you rough these things up before they stop working? What if I pre bend them to a bit of a C shape and adjust the slots to retain that bend? Then I'd get bending force if they still work at all. The only reason I tried this approach is noting that they trigger if you tap them sideways on the bed, certainly not optimal, but might work. Now if they'll still work pre bent, that'd give meby clearlynotstefan - General
So here's the idea I've been playing with for an effector. I'd love to hear your guys input before I tinker too much with printing and adjusting it.

Hey DC, Quick question. I'm considering making something of a flying extruder and I'd like to know if my duet wifi could play nice with my idea and how to do it. My tall delta is so big that I'm having retraction issues with my top mounted extruder and crazy long Bowden. I can't side mount it as I'm enclosing the printer. I might try a standard flying extruder but I see some drawbacks there tooby clearlynotstefan - Duet
