RAMPS itu arduino-based: Arduino Mega 2560. Jadi di Software/GUI Arduino tinggal pilih board Arduino Mega 2560 jika mau flash firware. Banyak elektronik lain yang arduino compatible yg intinya berdasaran chip ATmega, seperti Gen7, Sanguino, Melzi dll. Hanya sebelum bisa muncul di GUI Arduino, kita perlu simpen file hardware definitionnya di folder Arduino. Ga terlalu susah sebetulnya, kecuali ben

Elektronik menentukan fitur untuk printer yg akan dibuat. Fungsi min Elektronik standar paling tidak ada:
- 4 stepper driver output untuk x, y, z dan extruder
- 2 heater: untuk hotend dan heat bed (bisa jadi tidak diperlukan)
- 2 thermistor input untuk baca suhu hotend dan heat bed
- 3 min endstop input untuk baca posisi home sumbu x, y, z. Ada juga yg hanya perlu 1 saja untuk z seperti Tantillus

@Bru: so you have successfully burn the boot loader, that is good. To upload the firmware using the usb-ttl adapter cp2012, I need to push the reset button when the Arduino just showing 'Uploading' the firmware message.
Well, I manage to 'practice' it several time until get it correctly.

Halo teman repraper,
Spool Holder adalah asesoris printer yang saya rasa sangat membantu agar kita tidak perlu setiap saat memastikan filamen masuk ke extruder dengan mulus. Saya beberapa lama menggunakan spool holder ini: , cukup baik. Namun saya perlu spool yang berdiri di tengah-tengah printer dan dapat berputar lebih leluasa searah sumbu X. Akhirnya saya bikin arm untuk spool hoder dengan op

Sudah coba cari di glodok tempat jual komponen elektronik? Pernah nemu di satu toko, kalo ga salah "ok" (dibaca: oka). Ada barang tapi dia ga tau harga jadi ga mau jual. Aneh kan? Ga tau sekarang ...
Alternatif: di LTC lantai atas tempat jual2 lampu ada satu toko yg jual sensor & controller dr merek Autonics, termasuk stepper motor. Sayangnya waktu itu hanya ada yg 5-fase. Kekurangan: harga

Mantap!
Siap-siap aja kecanduan Sampai sekarang sy masih seneng ngeliatin print-headnya itu begerak menari-nari dan juga 'nyanyian' suara motornya saat ngeprint; dan juga kagum saat ngeliat hasilnya )

Halo Teman Reprapers. Selamat Tahun Baru 2014!
Semoga di tahun ini makin banyak yang bikin / punya printer 3d.
Bagi Anda yang ingin membuat printer 3d Prusa Mendel i2, kebetulan saya punya 1 set printed part. Material adalah PLA warna putih, diprint dengan 0.25 mm/layer dan infill 50% dan 3 perimeter/shell untuk memastikan part-part-nya kuat, kecuali endstop holder yang tidak perlu kuat 'hanya'

Could that be due to motor resonance?
I had similar issue on my Prusa. Lowering the speed/acceleration only make it less visible but still there if taken look closely.
Then I changed my X Y motor to Sanyo Denki 0.9deg/step with a dumper in the back of the motor. It gives me far better result even at higher speed I used to have the issue.
You said tried DRV825 motor driver then back to A988. Is t

Tantillus
The issue is when the firmware configured to have both extuder and bed but you only use the extruder, sending M104 and then M116 then you will wait forever, because the firmware expecting a temp set for the bed. We can workaround just heat the bed a little though so M116 will return

Thanks Subro Dewa atas sarannya. Memang bagusnya pake komponen, apapun baik elektronik ataupun hw, yang gampang ditemukan lokal. Nanti saya coba lihat FT232RL itu. Sekarang sedang ngoprek firmware Teacup
Btw Teacup juga bisa dipake buat CNC tuh, dan ukurannya juga masuk buat atmega 328.

Another one though, on the real running firmware I am stuck with M116 as could never get the 'Temp achieved' after heating the extruder to a target temp and wait for it. I configure Teacup with both using extruder and heat bed. And apparently M116 expects both extruder and bed temp to be set to return 'Temp achieved' whereas I just only want to heat the extruder and leave

Salam kenal bro Dewa, seneng ada yang berpengalaman di bidang elektronik bisa sharing di sini.
Setuju dengan apa yang dibilang soal berurusan dengan mikrokontroller itu. Pengalaman paling susah memang deal dengan si mcu-nya: setting fuse, upload bootloader, dsb. Maklum kemampuan elektronik saya cuma abal-abal.
ISP Programmer atau any programmer buat si MCU harus punya kalo mau ngoprek.

Mantap Bro Herman. Saya suka yang dual extruder itu. Jadi tertarik nih ke depan untuk bikin printer yang dual extruder.
Beberapa minggu terakhir hanya print parts pesanan untuk Prusa dan menyelesaikan satu printer lagi, jadi tidak ada yang bisa ditampilkan kecuali satu saja ini: Zombie Head Hunter. Kebetulan diprint di printer baru dan nyoba speed tinggi: 80 mm/s perimeter dan 95 mm/s infill. Ha

I am running Teacup (master branch) on my machine and have this issue: It waits for target temp to achieve for every move, so the extruder just pause for a moment between moves.
Initially I suspect every move needs to check for waitfor_temp, but it is not; and waitfor_temp only set for the M116 or anything calling enqueue(NULL). So then I excerpt some of the gcode of the first layer and remove e

The question is, is this the code from the master or experimental branch. I'm not sure wether all fixes for a smooth lookahead ride are on the master branch, because there's a fundamental flaw in jerk calculation. On experimental it's fixed. Experimental will go to master as soon as it's reasonably sure it doesn't introduce new flaws.
I use the master branch. I thought the fix is

Bisa beli atau bikin sendiri.
Beli online juga banyak yg jual, paling gampang nemu yg jual di ebay. Sebelum beli ya perlu nentuin dulu elektronik yg mana yg akan dibeli, makanya perlu baca2 dulu. ada banyak elektronik yg bisa dipake, yg popular misal: ramps, melzi, sanguinololu, printrboard, gen6, gen7. Yang terakhir itu, gen7, paling gampang dibuat sendiri juga. printer saya satu pake gen7 yg bi

Thanks for the patch. I think I have embodied all your fixes in this patch:
Also in the mac-simulator branch.
Can you try it and let me know if it works ok for you?
Ya, it is working fine. I forgot to tell that compiler give warning on 'hot' and 'cold' attribute in this kind of statement:
./dda.h:205:63: warning: unknown attribute 'hot' ignored [-Wattributes]

Thanks for making this. Now I am trying Teacup and playing with the simulation.
When compiling the simulation on my mac book, the compiler complain about this kind of line: TARGET startpoint __attribute__ ((__section__ (".bss")))
It says that it needs comma separated, so then I change this line and others similar to something:
#ifdef SIMULATOR
#ifdef __MACH__
TARGET startpoint __attribute__ ((__

I tend to believe this due to the stepper motor. I am having this issue with my first Prusa. Pulleys are alu machined, belts are good tension and have this tensioning system. The wave apparent if printing over 45 mm/s, very bad at 60. I can only print good parts at 35 mm/s and lucky to not have or only 1 small wave.
Just recently, couple days ago I finished my second Prusa. This time is using re

Printing
Wow mantap Bro Herman. Saya juga pernah print object yang kecil, Yoda dengan ukuran 25%-nya dari yang pernah diprint sebelumnya. Ukurannya jadi hanya seujung jari saya dan kebetulan ada teman yang foto dengan kamera resolusi tinggi.
Sudah lupa spek printingnya. Yang masih ingat:
- Material: PLA
- Layer: 0.2mm
- Slicer: Slic3r
- Printer: Portabee

Thank you all for your inputs. Shawn is too generous with the feedback
Anyway it is true that ppl get difference experiences, some hold true for me but not for others. Before this I have been printing with glass on top of hbp with 55-60 degC and been great, some pla tend to stick less and curl up, and setting the temp and speed just overcome the problem.

Today i just tried printing pla on the famous blue tape. the tape is on a glass and i run the printer without heating the bed. the print just stick well, even too well that hard to remove. especially the big part. there are two big parts left i just could not remove by hand. I dont want to use force first before asking. once in youtube saw ppl spray something before remove any part and then getti

Rata-rata ukurannya segitu. Tapi sepertinya kalo tape bisa saja pesen yang lebih lebar, nanti dipotongin sesuai pesanan.

Saya sudah coba blue tape ini dan hasilnya sukses. PLA nempel ke tape dan tapenya juga nempel ke bed. Bednya adalah kaca 3mm dan tanpa dipanasin dan juga tanpa acetone / alkohol.
Memang waktu nyopot lebih susah dibanding dengan print angsung ke kaca + HBP.

Thanks for the info, this is excellent.
I am trying it now. Installation of simulavr is straight forward and flawless by just following the wiki.
Now getting into trying the debugger section, I got this:
(gdb) load
Loading section .text, size 0x47fa lma 0x0
Loading section .data, size 0x3c lma 0x47fa
Loading section .eeprom, size 0x20 lma 0x8101000
