Duet3D PCB delta printer effector sneak preview
-
just hold off for a bit Lykle is still working on it with input from me as well.
He is adding the standoffs as part of the print we just need to get the hight correct first?
-
I think M3 screws make the job better. 2.9mm hole diameter is exact size of external dia of M3 thread so it seems that David chose this size for precize positioning with M3 screws, IMHO.
-
the fact that the PTFE Tube is locked in the bottom of the adaptor should locate it adequately
-
OK, after some work, and a nice discussion with Doug, I have wrapped up the design for the adapter.
It now features a nice set of integrated legs, 6.6 mm long as we want to make sure we do not bend the PCB when mounting the adapter. No idea if it will hinder the working of the sensor embedded in the PCB.
So the Shapeways model is now complete and ready.
The Thingiverse page holds the 2 models, the legless one and the legged one. (If you look at the adapter standing there you will realise why I am calling it the Grand Piano adapter)Shapeways http://shpws.me/OPLc

Precision could not be much. BTW I ordered the adaptor and it could be seen small feet on bottom of the adaptor onat the picture on the order status page. So it's possiblly no standoffs are needed.
-
yes indeed that is correct precise mount is important but the tube will locate it centrally anyway.

OK, you won. Your advices help me make another step building my delta so thanks anyway.

I think the Nimble is the way to go on a Delta, and after my aborted fiasco with the Distech Automation 2-1 effort im going with a nimble dual on my FT-5 too
I am impatient now !!!!!

Nice one Mark
Are you in Scotland?

I hav'nt included the part fan as I use the Berdair system
Dammit will you stop showing me all these nice pieces of kit, it seriously dents my wallet
That's the second time this forum cost me money, last time was showing the 20x40 kossel corners just after i had bought a 20x20 set…..

on you wiki there are only instruction for duet board
could you confirm us that it will be compatible with smoothie or marlin? -
It's designed to be compatible with other firmwares. The big question is whether the sensitivity will be suitable. The x256 stepper drivers on the Duet give low vibration levels, allowing the sensitivity to be set quite high without vibration from the motors causing false triggering. This might not be the case if you use stepper drivers with lower microstepping.
The sensitivity can be adjusted by sending a serial bit stream to the effector. So if support for sending that is added to other firmwares, any possible problems with vibration could be overcome.
The effector also requires a short delay between the end of a travel move and the start of a probing move, however I understand there are versions of most firmwares with this facility now.

This all looks fantastic. Can’t wait to order!
1. What’s the thickness of the carriage adapters?
2. Are some kind of technical drawings of the effector available (mainly for hole positioning), so I can make an adapter for my hotend?Thanks
-
1. 2mm
2. I'll ask Tony to do some.

How did you mount the berd air to the pcb effector?
Thinking of getting it myself

It is done by an adapter Doug has made up, I'm sure he will either make you one or share the .stl if you ask him.

I just amassed the parts to make one myself after seeing Dougal1957 name his.
The kit is $35.00 plus shipping but the cost of everything to make one myself via ebay cost me $9.54 including delivery
I bought the following
X1 24v air pump 4.5 litres a minute.
X5 meters of surgical tubing (very flexible so hopefully there would be no resistance to induce any effector tilt that stiffer tube might induce)
500mm of brass tube ( i will bend it and drill holes myself)I too would like to know the hole spacing of the ballstuds to allow me to print a bracket to hold the tube nice and close to the nozzle
-
Mark
The Ball spacing is 55mm on the tower side and 20mm on the short sideI Have Freecad design for a tube holder that I can share if you wish current variant is for a 3/32 inch OD Tube (The berdair one) but it can easily be modified for any size of tube. Do be aware however that there is an LED between the rods on the short side that needs to be able to shine thru the mount plate.
Let me know if you need the files and I'll find somewhere to put them.

It's 12mm between adjacent ball stud centres at each corner. You can find the design for the bracket I use to attach a print cooling fan at https://www.thingiverse.com/thing:2467663. The notch is to leave space for the illumination LED.

My Bad that's what happens when you go from memory!!
Mine for the tube is that spacing
