My 3d printer (work in progress) Hi everyone, I currently design and building my own 3d printer from scratch. The first fews tries failed with the x and y axes. I tried the ultimaker-style, but leveling linear guides was nearly imposible (and first I tried it with leadscrew [one linearguide per axis replaced with leadsrews]). So I try now the h-bot design, but I wait for a few printed parts to be printed (I don't have my own printer, so this is my first 3d printer). But I thought I upload the files for the printer. The chassis for the printer is made out of 4mm din a4 plywood. I will upload photos as soon as possible. There are no mounts for the xy steppermotors because I work on them for the moment. But maybe you can reuse parts of the current design for your printer design and maybe i have succses this time and it works. Everything is done in openscad. https://reprap.org/forum/read.php?397,821461,821461#msg-821461 Wed, 19 Aug 2026 13:53:54 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?397,821461,865439#msg-865439 Re: My 3d printer (work in progress) https://reprap.org/forum/read.php?397,821461,865439#msg-865439 A clock maker that showed precision could be done by hand tools
and he went on to get Longitude prize.

One of his clocks has been running with great accuracy for 300 years

He taught his neighbors to file gear teeth and produce gears

So .... a lot can be done with simple tools to make a great project

Also design, design, design

The printer printed one Test-piece fine, but after this print it doesn't want to work. The z-axis doesn't want to move correct. It skips a lot of steps now (especially by low speeds). It's more like stuck. In the beginning it I used an M8 threaded rod made out of zink coated steel, wich I swapped for an stainless steel one. Still doesn't want to work. I fitted it with an TR8 Spindle. Still doesn't want to work. I tried tmc2130 stepperdrive instead of the allegro ones. Still doesn't want to work. Set the current on the tmc2130 on 1.2 A and run them in Spread cycle. Still doesn't want to work. Reduced the weigth on the z-Axis in many ways possible. Still doesn't want to work.

I decided to give up on this printer and start from scratch and use on it what I learned on this one.

I do not recommend it design a 3d printer based on these files]]> DocRaptor CoreXY Machines Tue, 31 Dec 2019 18:24:10 -0500 https://reprap.org/forum/read.php?397,821461,856228#msg-856228 Re: My 3d printer (work in progress) https://reprap.org/forum/read.php?397,821461,856228#msg-856228 the_digital_dentist CoreXY Machines Mon, 08 Jul 2019 17:50:00 -0400 https://reprap.org/forum/read.php?397,821461,856225#msg-856225 Re: My 3d printer (work in progress) https://reprap.org/forum/read.php?397,821461,856225#msg-856225

After some calibration I got it working. The prints, well let us say they aren't the best, but I can work with them. I started to print some mounts for 8mm aluminum tube profiles. These parts will mount to the axis mounts to reinforce the printer. I upload this part. Also I upload some of the files of new parts for version 2 of the printer. This includes: Axis mounts with integrated 8mm tube profiles mounts for reinforcing, corected belt pulley mounts with offset for 4x8x3 mm ball bearings to be used as pulleymounts, axis bearing and linear guide mount in the version for 12mm bushing and 10mm bushing, stronger mounting points for 4x8x3 mm ball bearings to be used as return pulleys, and corner pices for the bottom under the printer with integrated 8mm tube profiles mounts for reinforcing, which also provides mounting points for a controllpanel and an ac socket.

You'll have to show us some "trophies". It is cooler because you did it yourself and you'll learn a lot. My first printer was a kit, my second printer was scratch built using a CAD step file a friend gave me of his design. I have hacked and improved it over and over again based on what I have learned on these lists.
And learned things NOT to do as well. 8-)

have fun,

You can download the files here (this will be the last time I upload them here) and in the future under a website I reused for this: mad-devs.de .

You should go for some bigfoot drivers. youll be able to handle much higher current. though i would suggest a cooling fan for the drivers.

Or use Duet electronics, which has the TMC2660 high-current drivers on-board. The Duet doesn't normally need a cooling fan unless you set the motor currents above 2.0A.]]> dc42 CoreXY Machines Mon, 21 May 2018 17:58:49 -0400 https://reprap.org/forum/read.php?397,821461,822876#msg-822876 Re: My 3d printer (work in progress) https://reprap.org/forum/read.php?397,821461,822876#msg-822876 warbunniex CoreXY Machines Mon, 21 May 2018 11:03:20 -0400 https://reprap.org/forum/read.php?397,821461,822851#msg-822851 Re: My 3d printer (work in progress) https://reprap.org/forum/read.php?397,821461,822851#msg-822851

Are the design requirements:

Not to be based on any proven design
Use only hardware that is handy
Print should not be visible when printing (hole cut in plywood - would not make it much more flimsy)
Bed leveling next to impossible
Do not use bolts or screws of the proper length?
Do not cut bolts / screws to proper length?
Do not use lock washers or stop nuts

I wanted to take a picture of the bed leveling system with springs and knurled nuts (like most printer have), where the printbed sits (a mirror. These were cheap in 15cmx15cm for 12 peaces in my local hardware store), but I forget to put the sd card in to the camera (genius).
With the bolt and screw and a few other things: Most of the stuf I used is stuff I have liyng around.
With the print being not visible: I have no proper saw and the saws (electric) my father have, well he say: 5cm is a small tolerance.

Drywall screw thru plywood not too good (point sticking out will make you bleed) --- why not bolt and nut?


Z Axis extreme cantalever
Drywall screws holding Z axis bracket?
Tubes as Z axis guides -- how will they ever be straight -- perhaps outside should be polished for bearings
Z-Axis bearings what are they

7mm plywood (not even 7 layer Baltic) has to be constructed like furniture to be strong and orthagonal (right angles)

It may print --- but NOT well / consistant

Perhaps a look at designs at Open Builds
