3DR "Simple" Delta Printer I have a Printrbot Simple I haven't used since I got my MendelMax 2.0 up and running. So I've been thinking about what to do with it. Then RichRap introduced his [url=http://forums.reprap.org/read.php?178,230812]3DR printer[/url]. I thought this would be a lot of fun to build, and figured I'd use the vitamins from my Simple for the new delta. RichRap's delta uses 6mm rods, and the Simple uses 8mm rods, which means I have eight LM8UU bearings. I thought about just buying new LM6UU bearings and being done with it. But I like to design things, so I thought I'd modify his designs to work with 8mm rods. Well, I much prefer to work in SolidWorks than in Sketchup, so I figured I would build new parts from scratch for the top and bottom, and the carriage. The idea is to use all of his other parts without modification. Well, I couldn't leave well enough alone. I figured that since I was designing new parts, I could also change from straight lines to curves. Here is what I have so far: [img]http://forums.reprap.org/file.php?178,file=18758,filename=Progress_2.JPG,download=1[/img] https://reprap.org/forum/read.php?178,244826,244826#msg-244826 Thu, 05 Mar 2026 09:41:46 -0500 Phorum 5.2.23 https://reprap.org/forum/read.php?178,244826,647392#msg-647392 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,647392#msg-647392

So some design implements on the Simple Delta, First after printing either set of stl files (6 piece / 12 piece), which are still on John_sl 's github, for the top and bottom, omit the smooth rod, just use the 2020 aluminum extrusion then second, print a set of carriages and effector head for the kossel those have everything needed for the GT2 belts and the rollers ride nice in the 2020 t slots, you can just increase/decrease your arm length accordingly.
I'm not quite sure what you mean by omitting the smooth rod? I already have the bottom pieces for the 3DR simple printed (9 pieces, I'm not sure where you got 12 from).

Will the files provided by Funkymonk also work for converting the 3DR to GT2 belts?]]> Darkblade48 Delta Machines Sat, 02 Apr 2016 01:24:55 -0400 https://reprap.org/forum/read.php?178,244826,647391#msg-647391 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,647391#msg-647391 ProfessorBean Delta Machines Sat, 02 Apr 2016 01:20:19 -0400 https://reprap.org/forum/read.php?178,244826,645784#msg-645784 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,645784#msg-645784 Darkblade48 Delta Machines Tue, 29 Mar 2016 10:12:15 -0400 https://reprap.org/forum/read.php?178,244826,634576#msg-634576 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,634576#msg-634576 ProfessorBean Delta Machines Thu, 03 Mar 2016 00:18:47 -0500 https://reprap.org/forum/read.php?178,244826,614182#msg-614182 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,614182#msg-614182 docdawning Delta Machines Fri, 22 Jan 2016 23:57:09 -0500 https://reprap.org/forum/read.php?178,244826,402135#msg-402135 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,402135#msg-402135

Hi John. Excellent work. Thank you. I may take the plunge soon.

For John or anyone,
I understand the intent to keep things small and "simple", but could this design be adapted to use extrusions to connect the corner pieces instead of the printed mid sections? I am thinking this would allow one to scale the print diameter.

Thanks.

Of course, you can do anything :-). Seriously, though, what you're describing is basically the Kossel design: [reprap.org], which is an excellent design with a lot of builders and support.]]> JohnSL Delta Machines Mon, 01 Sep 2014 22:12:51 -0400 https://reprap.org/forum/read.php?178,244826,402125#msg-402125 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,402125#msg-402125 DNA Playset by emmett, published Feb 10, 2012!]]> rhmorrison Delta Machines Mon, 01 Sep 2014 20:12:45 -0400 https://reprap.org/forum/read.php?178,244826,400839#msg-400839 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,400839#msg-400839

"The 3DR was a fun experiement and started me down the delta platform but I think tha'ts all it will be. I just can't bear the thought of printing an entire third frame to fix the issues with it without knowing if that's all that was wrong with it."

Yes, me too. Just finished taking the 3DR Simple apart. Now I have all the parts to build a Smartrap by Smartfriendz.
I will cut the 50cm rods to 30cm.
Use the Ubis hot end, printrboard, endstop switches, etc. Just need to build another extruder, since I move the Greg's Wade over to my Kossel.
The 3DR Simple is not scaleable like the Kossel and Smartrap designs.

If the Smartrap works, I will probably convert my Printrbot Simple to the Smartrap with 30cm rods. Then I will have two Smartraps and a kossel.

I printed DNA parts, the nucleotides ATGC with the international approved colors, A is green, T is red, G is black, C is blue. Then snapped them together and made a helix.

Richard,
I found the issue with my 3DR simple, I believe. I gave up on it for a while and built a MK from ultibots that prints fantastically. During that build, I decided to print a "torture test" model on the Cupcake CNC that I had used to print both of the frames on the 3DR simple. Well, after the torture test model was complete, I examined it and found that the square box was out of square. My X and Y axes aren't square to each other. It's a real punch in the gut to know that this has existed. I think I will build a Z-probe for it and attempt to use Rich Cattel's auto calibration firmware. If that doesn't work then I'll print a new frame on the MK and try one last time! IF that doesn't work then the parts are going into a Tantillus!
for what it's worth, I was able to calibrate the MK in about an hour manually. I haven't fine tuned it like you have yours. I just don't see that I have a need to get that good with it.

Great! Good to hear your insightful problem solving skills are working for you.
Unfortunately, I don't believe the Auto Calibration will help you with the XY axes being out of square. But I've been known to be wrong. The auto calibration is to make sure you have a level/flat printing plane across the whole surface.
Not being square could be a structural issue, or a steps/unit calibration setting in firmware.

not sure whether to upgrade my Printrbot Simple to XL or to build a new Delta/Kossel with parts from 3DR Simple and new parts, like Azteeg X5, 2020 to go bigger and stronger, sliders by Jay Couture.......

Take Care

From what I understand, the autocalibratoin in RichC's firmware will determine tower errors and make corrections. I'm not interested in it, though. I believe I will be taking apart my 3dr simnple and making either another MK with 2020 extrusions and printed sliders or I'll build a CoreXY printer.

(I've since moved the extruder closer to the center of the printer to reduce the length of the Bowden tube, and made other changes which you can see in some of the pictures below)

I ended up going with an E3D hot-end and needed to make several modifications to the effector:




You can download the design here.

I also made a blower fan mount and blower duct that work great with the new effector.



I also made an adjustable mount for attaching an LCD:




I also made a quick-but-suprisingly-effective mounting adapter that allows me to mount the RUMBA electronics to the top of my 3DR Simple:



Thanks John for coming up with this 3DR variant! I've quite enjoyed building it.

And, finally, self replication:

I have a question. My motors are 1/16 step. w/ a4988s. I use Rich's spindles. When I try fine adjusting the z in Repetier using manual controls. If I am say lowering the Z with the 0.1mm arrows. I can observe maybe 2 or 3 movements then upon the next click no movement at all. Someone said that the steps are not fine enough to handle 0.1mm? In Jay's video he is tuning to the next decimal. 0.XXmm. Am I not understanding the resolution here?

Should every 0.1mm click on the z axis register 0.1mm?

Yes,the motors stop and thehot end drops, all the time, every time, yet this is not important to the results.

when printing the motors are always "on"
when you are leveling the print plane with the nozzle the motors should always be "on" and the nozzle "HOT" because it gets longer/closer to the print bed when hot.

look on Youtube for Jay Couture videos about calibratin and leveling the print bed by printing part of one layer of a square.
This way you can get it down to 0.02mm but only after you have done the paper test with a hot nozzle and the motors on.

Thank you. A fellow Delta guy was helping a newbe (me) to calibrate my 3DR. The he set it to go to 3mm off the bed. But after a bit of a chat it had dropped. He suggested the problem was my spindles slipping, even though they are amazingly tight, and there was vurtually no forces on the motor. We did change that motor timeout in configuration.adv.h from 60 to 400.

I was concerned that maybe my Spectra needs to be tighter? But if you say that the motor will shift a few degrees upon losing its power, I won't worry about that.

I was told that because it was doing that, he could not calibrate it for me.

So close. I've been working on this thing for 8 months. I figure I'm at 98%. I have a J-head issue to resolve, This calibration and I should be printing soon.

Thanks![/quote]

Weird, what do we do when we get advice that turns out to be misdirection? We learn?

You should be able to get within 0.1mm using post-it notes. I use mini-post-it notes. Then....
Use this youtube video and you will get within 0.02mm across a flat print plane.

edit: Almost forgot to mention -- I'd love to be able to run my 3DR simple as a standalone unit when I bring it around for demos, but doing so will require adding a LCD with input. I already have a Printrbot LCD screen, but I don't see it supported in the Marlin firmware unless I missed something. Anyone have pointers for getting a LCD added quickly?

Hi!

I'm running: Ramps 1.4 w A4988. Spectra line with Wantai Nema 17 Stepper Motor 42BYGHW811 70oz-in 48mm 2.5A.(Same a Rich used on his from the blog).

Is this normal?

I did some testing. If I do the paper calibration, I bring my nozzle to the bed and I have just enough clearance. I can still move the paper. If I cut the power, I can no longer move the paper, or slip it under the nozzle. the nozzle has dropped.

I did increase the DEFAULT_STEPPER_DEACTIVE_TIME to 400 from 60.

If I G28, then cut power it does drop a tiny bit. Maybe 1mm? The effector will very easily stay in the top position. In fact it still requires some force to manually push the effector down.

I can't measure the difference, but I'd say it is 3-4 times harder to push the end effector up as it is to push it down (without power).

Prior to trying to calibrate this today. My end effector was parked at the top. It did not appear to be slidding down, even after a couple month of no power. So, it's not as iff it is slowly rolling down to the bottom. What is obvious now is that tiny (1mm?) drop at the removal of power.

So, I don't believe it is the firmware, I corrected the timeout
I don't think it is the spectra .

And these are supposed to be good motors. Same motors RichRap used.

Any thoghts?

Thanks

Maxi



And my end effector is pretty light.]]> disneytoy Delta Machines Thu, 26 Jun 2014 15:59:04 -0400 https://reprap.org/forum/read.php?178,244826,371837#msg-371837 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,371837#msg-371837 6 all the same for 3 on top and 3 on bottom.

Anyone had problems from slightly warped parts or too tight a fit?

My towers ended up slightly angled, since i had to force them into sockets.
Is that a common kind of problem with the design?
Maybe add some bolts to secure them in an initially more wobbly socket ala rostock (to allow for adjustments)?

The frame itself (4 bolt per link version) appear quite rigid, definitely more so than my wood + smooth rods rostock variant that wobbles at any interesting speed.

It took me about 9 hours (morning to evening), to print the 9 parts of the base on two printers running at 20 mm/s and 40 mm/s, with 0.4mm layers.]]> Artlav Delta Machines Mon, 09 Jun 2014 15:46:55 -0400 https://reprap.org/forum/read.php?178,244826,367362#msg-367362 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,367362#msg-367362
I have finished reprinting my frame pieces and will begin moving everything over to the new frame. My previous frame pieces were not that great quality wise due to slicer and printer related issues. The new parts are some of the best parts I've ever made.

For what it's worth, I transitioned away from Kapton tape on glass to just hairspray on glass. The ABS sticks like mad when the plate is hot and just pops right off as it cools down. The surface finish is a nice matte finish and I had ZERO issues with warping because the first layer stuck so well to the hairspray/glass.]]> umdpru Delta Machines Mon, 09 Jun 2014 07:53:58 -0400 https://reprap.org/forum/read.php?178,244826,367021#msg-367021 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,367021#msg-367021

Very nice!

I'm quite jealous, actually. Did you have any difficulties calibrating it? What did you use to print the parts in the first place?

I had a thought last night that my steps/mm for the three axes could be causing my problems ( I left them at 55.5 default). I calibrated those and everything is very close so that wasn't it. I'm back to waiting to finish printing a new frame.

I'm seriously hoping that the frame is the issue.

Took a bit of tinkering to figure out how to calibrate it (described in the previous pages of this thread, I believe). Parts were printed on a RepRapPro Mendel in ABS, although that took some effort as well because it's not an enclosed unit so I was fighting warping issues.]]> PierreB Delta Machines Sun, 08 Jun 2014 12:55:50 -0400 https://reprap.org/forum/read.php?178,244826,366077#msg-366077 Re: 3DR "Simple" Delta Printer https://reprap.org/forum/read.php?178,244826,366077#msg-366077
