First off, a big thank you to everyone who has responded so far! QuoteTrakyan I can't pitch in much on the hotend side of things, since I've only used Mk. clones and V6 clones personally. And what has your experience been with the V6 clones? Good, bad? Do you ever wish you bought the genuine E3D?

Quotekapperi Also I have Tevo titan type extruder and had to change bigger stepper to it, now its working right. I have to test petg again with higher temp... I'm looking at using two Tevo titan extruders for my IDEX style 3d printer design. Do you have any specs for the stepper you needed to get the Tevo titan to work correctly, and on the one that didn't have enough power? It might save me fby Don McLean - Printing
I’ve been working on my 3d printer design and collecting parts for my upcoming build. I’ll be using two independent IDEX style heads. My original plan was to use two Chimera clones, for ease of mounting, and to only use one nozzle from each chimera. That, along with two Bowden style extruders. I have since realized that the Chimera clones all have PTFE liner all the way into the heat tube, soby Don McLean - Reprappers
deckingman, that's a good idea that I haven't considered. Here's a YouTube video I found of a tall narrow print So I've still been mulling around in my mind as to whether or not I want to experiment embedding continuous strand fiber in my prints at some time in the future. Not sure if it's worth the hassle, but also it won't be possible if I go for the vertical build. But I can do other reinby Don McLean - General
o lampe, that's an interesting suggestion. So would you pause the print after it has started in order to clamp the bottom of the print? I'm not sure how that would work? digital dentist, I've looked through your blog, thank you for sharing! I agree with you that a belt isn't a bad choice for a Z axis. I looked at your stretch calculations, and I think that the flex couplers that attach theby Don McLean - General
I was just looking at the CR-10S5. That thing has a build area of 20" x 20" and that's just some V-slot bolted together at right angles, and that could be stiffened significantly. Only 10 more inches to get to 30" in one direction, although I really wouldn't need the 20" in the other direction. So I think it is viable to modify an existing printer, although I haven't decided if that's what I wby Don McLean - General
QuoteDjDemonD I like your go for it attitude Don but in Olampe's defence 30" long parts are on the extreme upper size for reprap style printers. Thanks . Most reprap style printers use unsupported round rod of small diameter, like 8mm or 10mm. The deflection of a beam is based on the length cubed, so once you get to a certain size, they won't perform well. There are many larger reprap printeby Don McLean - General
Quoteo_lampe Wouldn't it be easier to ask a professional maker shop to print these things for you? I'm going to flip that around. Do you own a 3d printer? Why? Why don't you ask a professional maker shop to do all your 3d printing for you? Also, I'm pretty sure that having a pro shop that can do those lengths, well it would cost an arm and a leg, probably the same cost for me to make my own pby Don McLean - General
Thank you to everyone for the replies so far! dc42, that's good to know about the RPi. Let's say for argument's sake 2" x 2" x 30" as the worst case scenario. deckingman, yes, for a vertical build, a long Z axis that moves only in Z. Yes, I'm concerned about long parts being knocked over. DJ, yes, I hear what you are saying. Hopefully I can build a machine where I can modify it if needed wby Don McLean - General
Thank You everyone for your replies! I'm just so indecisive. Probably a big part of that is because this is my first 3d printer build. Also I want it to be my last 3d printer build, knock on wood. Unless it works awesomely, and I want another one so I can print two printers at the same time . So some of the issues that I am thinking about..........I found these videos on YouTube, I am not affby Don McLean - General
Let's assume that I will reinforce the printed parts with CF cloth afterwards so that the strength derived from the layer orientation isn't a factor. In this case, which would be a better machine to build?by Don McLean - General
Thanks for the reply! I don't know how much the strength will be affected by vertical printing of long parts that aren't particularly wide, but there may be a few simple ways to reinforce the parts if printed vertically. So that definitely influences if it will "work right" and it is unknown to me at this point. I assume that they would work right either way. If you're talking about print oriby Don McLean - General
I just can't decide what to do. I want to 3d print objects about 7" x 30" x 5" although I'd also like to print some things around 12" cubed but that isn't my main reason for building this . I was also thinking about using some Nylon X or similar nylon & carbon fiber filament. I have decided to go with an IDEX style dual print head.

QuoteTrakyan QuoteDon McLeanTrakyan, idlers typically have a bearing in them, or bushing, or something to help them spin. So no, I could just bolt them in place, perhaps with the help of a few spacers. At least that is my understanding. They are not the same thing. Sorry, my bad (wrong terminology/poor explanation). Not an idler pulley, just regular old pulley with a set screw. You'll be mounby Don McLean - General
Does anyone know if I can add a single servo control to any of the previously mentioned options? I'm not talking about a servo motor to spin a belt, I'm talking about a single servo the kind you might find in a radio controlled airplane, normally used to move a rudder or elevator or aileron on a RC plane?by Don McLean - General
I should also mention that I am considering a fixed gantry, either with a cantilevered short axis (I'm making a rectangle printer, not a square one) and moving bed in the Z, or like the makergear machines like the one in this review But much larger, and with two Z axis, one on each side.by Don McLean - General
Apologies, deckingman, I blame the holidays for making my brain frazzled. I actually did spend quite a bit of time on your website. Thanks for the info . I was wondering where all the build logs were for people who made their own printers? I'm wondering if I should do a design log here?

Quoteampapa Not that my opinion matters Your opinion certainly DOES matter. Thank You for posting in my thread. dc42, really impressive machine you made, also I'm very impressed by the dual level homing from the duet. amigob, thank you for the suggestion, I'm seriously considering it. QuoteTrakyan As for the dual independent print heads taking up a lot of space, they shouldn't take up muchby Don McLean - General
Thanks to everyone who has responded so far and for all the suggestions! It's taken me a while to research some things, but I still don't know what I'm going to do, so it's still a work in progress and I still need help. I was looking at the duet a bit closer. Yes, I found the Canadian distributor, it's $400 Cad + tax for the bare bones parts. It looks like it uses the trinamic drivers. www.by Don McLean - General
Quotedc42 So you want 7 or 8 independently-driven motors. One option for you is Duet WiFi or Duet Ethernet, plus DueX5 expansion board. That combination provides 10 stepper drivers with the possibility of 2 more external drivers. I'd definitely choose an Ethernet connection over Wifi. I've watched a couple videos about this controller just now, thank you for the suggestion, wow, seems very caby Don McLean - General
Thank you for responding to my thread. I'm not sure I explained it well. I would be replacing the bed with a larger bed, that would now be driven by two screws instead of one, and 4 linear guides instead of two, reusing parts from both printers. Many printers have a Z axis driven by two motors, with two screws, and multiple guides. The boxes would be extensively modified and reinforced so itby Don McLean - General
I've been looking at 3d filament printers. The ones that are commercially available just can't do what I want to do. The build areas are too small. Some have very tall Z axis, but this isn't a priority for me. It's not the build volume that is important. I simply want more movement in either X or Y. Also, for the cost of a new printer, I can build one with better linear components. I have sby Don McLean - General
I’m in the process of designing and implementing my 3D printing strategy. Woah! Yep, big words there. So I have bought a projector and I will be making a DLP printer. BUT, I have also realized that there are some advantages of a filament printer. In particular I’m looking at some of the materials available. So I am building a combo machine.

I made my first technical post here: I'm thinking of trying a 3LCD projector. I haven't seen anyone else do it, but also, I haven't seen anyone else try the modifications I suggest. Not sure if it's a great idea.by Don McLean - General
I may end up with a 3LCD projector. I've been thinking of how to modify it for resin printing. I looked at some examples of people who made their own 4K projectors using a single UHD LCD with good results, but this wasn't for 3d printing, just for viewing in UHD. For a printer, only monochrome is needed. So only one of the 3 LCDs would be needed. The white light is separated by wavelength filterby Don McLean - General
