A well made flying extruder is probably 'best of both worlds' A short Bowden tube won't cause oozing and the weight of the extrudermotor is supported by the gimbal. You only risk resonance between gimbal and hotend/effector at certain speeds, but you can avoid it with propper slicer settings. ( The effect shows up mainly during infill, so it might be not critical )by o_lampe - CoreXY Machines
QuoteLFG Please bear with me I'm a civil engineer. I can calc you storm water and size a foundation but I have no idea what you mean when you say enable internal pullup resistors. Are you saying to un-comment the X/Y/Z min endstop pullup in the marlin code as shown below? // Enable pullup for all endstops to prevent a floating state #define ENDSTOPPULLUPS #if DISABLED(ENDSTOPPULLUPS) // Disablby o_lampe - Extruded Aluminum Frames
Those cables are fine, the fibre isolation will stand the usual heat bed temps. I'd be more concerned about the huge amount of power. The thermistor will reach target temperature in no time, but you should consider waiting some extra minutes to allow the cast bed to spread the heat evenly.by o_lampe - Reprappers
There is a Marlin section down the forum tree, where you probably find the answer. I'm sure you're not alone... When you can't revers extruder direction, you can always turn around the stepper connector on the controller board or switch the order of wires in the connector.by o_lampe - General
The difference in PCB endstops and simple switches is: the switches need internal pullup resistors enabled in Marlin. You can test them with the M119 command sent from a PC-host program like Pronterface or Repetier host. When they report 'triggered' although they are not pressed, you also have to invert the endstop-logic in Marlin. Even when you found the right coils from your stepperwires, youby o_lampe - Extruded Aluminum Frames
I wonder if it would make sense to buy the watercooled hotend kit and upgrade my existing Delta? Would it work with dc42's Smart-Effector? Is the flystruder gimbal 'universal' or would it only fit a Zatsit-frame? I'm afraid you will have a hard time to reach your campaign goal, now that the early bird kits are all gone. You could sell more of the above mentioned items, when you mention in kicksby o_lampe - Crowdfunding Projects Announcements

QuotePoorly made machine have their belt not tensioned enough ! Acrylic frame, extrusion not beefy enough, flimsy 3D printed parts etc... Agreed. That's why I prefer guiding the belt ( or cable ) through the slots: there are no sideloads on the extrusion...no matter how tight.by o_lampe - Mechanics

It would be great to find a method which produces Carbon from CO2. Preferably an exotherm reaction which needs no additional energy except for the start. Or extract the Carbon from a reaction between plastic, CO2 and saltwater. Abracadabra, there's something useful like sweetwater and fertilizer coming out off the exhaust.

If you are using a non standard hotend with a more powerful heater element, you have to run the PID tuning command. Also see M301, how to set the new found parameters in Marlin.by o_lampe - Prusa i3 and variants
Quotethe_digital_dentist The teflon in most (some?) doesn't extend down to the heater block- it stays up in the heatsink, so it never sees the high temperature. Except in all metall hotends, there is always? a short piece of 3OD x 2ID mm PTFE tube in the bottom of the heatbrake. Right where the heat is. But I can only refer to clones.by o_lampe - Reprappers
I wonder how a PTFE-liner inside the heatbrake will survive the 285°C treatment? I always tighten the hotend when cold. The only one leaking was the cyclops-clone, because nozzle and heatbrakes don't meet.by o_lampe - Reprappers
I thought the garbage collects in the middle of the Ocean, where wind and waves are calm or moddest? The island would tend to rotate with the current, but it's super slow ( rotation maybe helps growing crop? )by o_lampe - green talk
Maybe this design of my 'compact carrier' helps understanding? It is designed for 'Bosch slot5' extrusions and works surprisingly well on my Delta. They are made of PETG, which allows me to tighten the belt without breaking the clamping part. To connect open belt together in a 'twisted' fashion, I simply CA-glued them. That's strong enough, but only works on straights. No bending allowed.by o_lampe - General
I've also made experiments with fixed cable and the 'walking' issue was pretty neglectible for a 200mm travel. Now I think of a combination of the Cloverleaf drive and a fixed cable. That could eliminate walking and slip once and for all time. @TDD I agree with the cable stretch. I had to retension it very often in the beginning, because I didn't 'prestretch' it before use. Once it has stretcheby o_lampe - Mechanics
That's another problem: most of the plastic material drifting in the sea has an equal or higher density than water. It sinks down, until the density is the same. How would you make such plastic float? You can't just press a brick off it...and making reliably airtight containers from a mix of plastics is a 'wet dream' in a double sense of meaning.by o_lampe - green talk

The cure time of concrete is important in this type of construction. They usually let it cure over night to avoid cracks. If you had fast curing concrete, you'd have to mix it 'on the fly'.

A good fertile ground can't be made easily. We'd have to steal it from somewhere. Those garbage collections are far away from any current or coast. In the eye of the hurricane if you will.
