Hey, A2. I've been following your post regarding your DLP printer and was wondering if you could share with me how I could build a z-axis using v slot alu profiles, lead screw, and stepper motor. OpenBuilds.com has a 8mm acme lead screw (currently out of stock), do you think this would be strong enough and good enough to achieve 10micron layers? Also, with regards to the VAT bottom what materialby NewKidOnTheBlock - General
QuoteA2 Print speed is determined by how many lumens your projector has, and the Z-axis mechanics, it can be as high as 50 mm/hr, but I think most are around 35 mm/hr. I'm considering 26 mm/hr with a 0.10 mm Z-axis resolution. One full step (no micro stepping) of the stepper motor advances the Z-axis: .02623 inch/200 steps/revolution = .00013 inch, (0.00330 mm). That's over kill on the Z-axisby NewKidOnTheBlock - General
What is the required ansi lumens rating does a DLP projector need to be in order to be able to cure resin?by NewKidOnTheBlock - General
QuoteA2 QuoteNewKidOnTheBlock What's the biggest build envelop possible for a DLP SLA printer without sacrificing resolution? XY resolution is dependent on the size of the projection, and the number of pixels, and the Z axis resolution is determined by the mechanics of how you drive your zed axis. So you have to determine what resolution you require to determine the maximum XY print size. I'mby NewKidOnTheBlock - General

At what point does hysteresis not become a factor when using a bowden style filament extruder? Werner: Could you please list the vitamins that are required to build a BerryBot?by NewKidOnTheBlock - General
Eric: Those pictures you posted above really help with understanding the different zones in a hot-end. What would be the best set up (using the pictures from above as reference) to ensure no jamming or other common hot-end issues?by NewKidOnTheBlock - General
Thanks for the update, Eric.by NewKidOnTheBlock - General
Thanks, Eric. I saw the pictures of their prints on their website also. I'm really curious to hear about people's personal experience with the PICO hotend. They make it sound perfect and flawless... Would like to get more feed back from people that have experienced the PICO to see if it's worth the money.by NewKidOnTheBlock - General
Any new reviews, pictures of prints, etc regarding the PICO hotend?by NewKidOnTheBlock - General
QuoteSublime It is a small program that allows you to change extruders for different sections of a print. It currently lets you select which extruder is used for (outer perimeters, inner perimeters, sparse infill, solid layers, support and support interfacing) as well as changing the retraction value for each nozzle since each plastic type has different properties. It also adds a prime pillar soby NewKidOnTheBlock - General
Sublime & bobc: You both are very well experienced individuals in the 3D print world. Please, let's let the past be done with (water under the bridge) and let's focus on helping everyone else grow the reprap world. Both of you offer much needed and appreciated knowledge. bobc: I would love to learn more about your experience with the Kraken, and if you wouldn't mind sharing some pictures ofby NewKidOnTheBlock - General
QuotemrPrik kraken looks awesome I would agree, from a technical stand point the Kraken seems to be an awesome unit but does anyone here have any actual real-life experience using it? Would love to see some pictures of prints with the Kraken.by NewKidOnTheBlock - General
QuoteRP Iron Man QuoteNewKidOnTheBlock Vinny: Where did you purchase your magnets from (they look super strong), and with regards to geare- stepper motors, does a bigger differential difference mean better for filament extruder (ie, 10:1 > 5:1)? There is a trade off between torque and speed. I think vinny is talking about the 5:1 geared Nema 11 steppers that Werner uses for his direct driveby NewKidOnTheBlock - General
Quotevinny I did order up some magnets though because even if I don't use them on a printer, magnets bring out the child in me and they are just plain fun to fiddle with. Just to illustrate the strength of these little bad boys, here's a picture I snapped earlier. Just for reference, I have huge hands so these things dangling from a magnet force through my finger is no small feat. Very impressiveby NewKidOnTheBlock - General
Wayne: That is a sweet machine you got there. What's the highest resolution you are able to print with your berrybot?by NewKidOnTheBlock - General
Eric & garyhlucas: I appreciate your emphasis on knowing how to utilize 3D modeling to make life easier when it comes to building something. Will keep you guys updated with the process of my build.by NewKidOnTheBlock - General
Wayne: Thanks for answering my question. Eric: Not everyone has access to expensive software and knows how to 3D model, and despite all that great things are still made by those people. I'm not arguing that learning how to utilize software to assist in 3D modeling isn't a good thing, I'm simply stating that believing that you absolutely must know how to 3D model via software first before buildby NewKidOnTheBlock - General
QuoteRP Iron Man QuoteNewKidOnTheBlock garylucas: Are you actually trying to say that I need to know how to use 3D model software first before I can build a 3D printer and start printing stuff? That's like saying I need to know how to write code before I can put together a computer tower LOL. Anyway, back to business.

Quotegaryhlucas By the way. You want to do 3D printing. Unless you want to only print stuff other people designed then you are going to need a program to produce 3D models. So really that should be your first purchase not the last. If you get that first you will be able to answer all your questions before you build stuff that won't work at all.

Quotegaryhlucas New, You want a big build envelope for big parts. So it is likely you'll need an enclosure to control temperature. So you will find that you either need to put the three columns very far apart or make your enclosure a hexagon. My calculation comes from the 3d model I've done in Solid Works for the printer I am building. This one is for a friend and if it comes out well I hope to sby NewKidOnTheBlock - General
Quotegaryhlucas New, If you 3D model a Berrybot for a build size like you said you will find out that you can't enclose the triangle without losing a huge amount of your built area. So to get the size you want with 3 towers and enclosed it won't fit through a standard 36" door opening! Just a thought.

RadRacer: Are you saying that NEMA17's are better than NEMA23's? I thought NEMA23's are more powerful, no? Also, what profile of aluminum extrusions do you have on your BerryBot for the main pillars 20x40 or 40x80? What would you suggest for pillar extrusion thickness if I am planning on building a similar machine but with a build envelop of 20"x24"?

First and foremost thank you for sharing your innovative upgrades to the Delta design. You have built a beautiful machine, Werner. I was wondering if it is possible to upgrade this current design to utilize the E3D Kraken 4-nozzle hotend for mutiple material/color printing?

Awesome job on replicating the BerryBot. Your machine looks sweet. Just out of curiosity, is it possible to upgrade this current design to utilize the E3D Kraken 4-nozzle hotend? Also, if one was to scale up the BerryBot design to have a build envelop of 18"x24" (DXH) what would need to change besides the print surface and longer pillars?

Quotezelogik @Newkidontheblock: So have so much question, that only you can response with your experience and calculation etc... The more easy to you is to draw your project/frame on inventor/solidworks/cao program and simulate deformations, moments, constraints. For the shaking, it's because I have put too soft vibration dampener for the foot, and it's the complete "tower" that shake. Thank yby NewKidOnTheBlock - CoreXY Machines
