If it helps when I was making the groovemount Piezo20 units I made the groovemount fractionally oversized, figuring it could always be filed down slightly to fit, rather than be too loose.by DjDemonD - General
For marlin try these settings: It does not matter if it triggers when moving or printing, only if it triggers during a probing move before it touches the bed (or fails to trigger when it touches the bed). You have a dual extruder setup and your piezo implementation is basic, but it possibly will work, these are very versatile devices.by DjDemonD - General
I think I've heard about it happening in the past perhaps once. And with 3mm yes. Don't worry if there is a little ceramic missing, in terms of function it makes almost no difference.by DjDemonD - General
Quotetekkydave QuoteDjDemonD Quotetekkydave Hi. Does the Orion use 2 separate piezo discs as opposed to a drilled one? The Orion uses Piezos soldered to a pcb. The pcb has a hole in it. So the filament isn't going through a hole in a piezo. I seem to be having issues with my PP20 where the filament is catching on the sharp edge of the drilled hole. Could be a good reason to upgrade to the Orionby DjDemonD - General

Drilled Piezos underneath the bed can work heat isn't as much of a problem as with fsrs and piezo are way more sensitive. That being said a carriage mounted plate can also work. Unless you intend to make your own circuit I'd suggest using our universal kit pcb and a selection of Piezos and see what works.by DjDemonD - General
Well you are going to lose 18mm. So there is maybe a way to put a sensor in the bracket that holds the hotend assembly to the carriage here is something I tried and it works, but its beta its not a turn-key solution it will take some time to get right for your setup. But its worth it piezo sensor are precise instruments but this means they take a little time to get right. You could also try anby DjDemonD - General
Quotehardy1234 Hi guys, what is the best position for the piezo? I'm not sure. Since I have a moving bed y axis. I have this printer. And this holder as dual Im not so good in redesign I hope you can help me thanks. I had already tried FSR sensors in stamps but these have lasted since I had them on the 3 stops from the moving bed. That was not good I hope this solution is a success Grby DjDemonD - General
QuoteJoeK1973 QuoteDjDemonD We haven't yet come up with a definitive solution for an original i3 mk2/3 machine mainly due to not having one to play with, but a mk1/1.5 rework type I3 can easily use the Piezo20 or the new Orion sensor, just insert it into the groovemount and insert the hotend into the sensor.

I've been thinking this way myself but haven't had the time to really fathom out how this would work.by DjDemonD - Delta Machines
I tried 1/64 and they were quiet, but they are quiet on 1/32 and I'm using an 8 bit controller so the number of steps/mm would be too high to achieve any reasonable speed at 1/64th. More microstepping does mean less noise. That's why tmcs with 1/16th interpolated to 1/256th is both super quiet and very fast.by DjDemonD - Stepper Motors, Servo Motors, DC Motors
Yes but the premise of this is which is better red tshirts or blue ones, when I'd say black. RRF on duet probably offers the best solution for delta printers, Smoothieware is also very capable. Marlin works too but I have not used repetier so can only say I am told it can generate more steps/sec than marlin so for 8 bit boards can achieve higher speed without sacrificing a graphical display.by DjDemonD - Delta Machines
No the delta kinematic (as implemented typically in 3D printing) is a mechanism using parallel rods to position an effector and attached tool in a defined 3d dimensional volume. The way it prints is exactly the same as a cartesian machine. However the print head, rods and carriages are optimised to be lightweight. The moving mass is therefore low compared with other schemes which enables consideby DjDemonD - Delta Machines

I've built a machine very similar to the one you show but using a cylinder as a frame. Definitely think about the steps/mm, mine runs 400 which does work fine, although I have not experimented yet with high speeds as I haven't had time. Perhaps using ballscrews offers a better chance of the screws being straight. As using smooth rods, especially long ones, will result in possible lateral wobble.by DjDemonD - Delta Machines
Beat me to it. LOL So for VR1 you can use normally a 0.4Mohm resistor.For underbed setups which are usually much more sensitive, you might consider soldering a second one on top if it's too sensitive to lower the resistance. For VR2 you need to be able to adjust it, there is no fixed value that will definitely work but something in the range of 0-100Kohm?? Idris?by DjDemonD - General
You'll still get some issues at 35 but it's better than room temp. 45 is better still and reasonably easy to achieve. Pro machines go up to 80.by DjDemonD - General
Some sort of standard connector would be very useful. It's conceivable that a hotend could have a 4pin plug with two 4A and two (four) much smaller connectors for a thermistor (or pt sensor). But having a universal unit for a print head is much more difficult it will need spare unused pins for any number of possible configurations of 1-4 hotends, parts fan, hotend fan, sensors, servos etc..

I stretched it and it stretched the same amount as the previous eBay special belt which was sold as fibre/neoprene. So I presumed it was not any "superior" material. It wasn't particularly expensive £3.99/meter.by DjDemonD - General
