Turn Your Arduino Into an ISP. There are a few instances in which it is neccesary to program microcontrollers without a bootloader.
For example, if have run out of storage on a chip you can get an additional 2KB when you program without a bootloader. Another example, the one I will show you how to do, is to program chips that have no serial capabilities and therefore cannot use a bootloader. The ATtiny85 is one of these chips. To program the ATtiny85 using the Arduino ISP you must first add ATtiny85 support to the Arduino environment: * Download attiny45_85.zip * Unzip the folder * Copy the folder to the Arduino IDE's Hardware folder * Reopen the Arduino IDE, you should see the ATtiny85 in the Tools >> Board menu.
Skeinforge 40 + volumétrique de calibrage - Josef Prusa RepRap 3D tisk. Wednesday, June 8th, 2011 n this article I want to help you with SF40 calibration.
Main difference over older version is volumetric flowrate. It basically means that SF counts how much of the plastic its should extrude for given layer height and width of trace (height*width*lenght = volume). Most confusing on all this is to realize SF uses the length of filament which goes in instead of extruded thread which goes out. For that you need to set your e_steps_per_mm in your Firmware to count with filament instead of extruded thread. RepRapCalculator. Flux de production pour une RepRap. A l’issue du premier atelier RepRap & BBQ de cet été, nous avons testé une série de logiciels fraichement développés par la communauté.
Voici la liste des logiciels utilisés. Le résultat est très encouragent et contribue à unifier le flux de production indépendamment de la machine que vous utilisez. Le firmware (avec gestion de l’accélération et une régulation de température fiable) : Pour piloter la RepRap : Multiplateforme car écrit en Python et wxpython. Pour compiler les .stl : Mettre le dossier ensuite dans celui de Printrun et le renommer "skeinforge".Vous pourrez alors l’appeler depuis Pronterface l’interface graphique livréedans Printrun.
Pour calibrer l’extrusion C’est à dire mesurer la quantité de plastique qui entre dans l’extrudeur (Première chose à faire dès que vous obtenez uneextrusion fiable sur votre extrudeur) : Pour calibrer la géométrie (avoir des côtes correctes) Still Extruding: Configuring Sprinter Firmware. PCPowerSupply. Electronics prepared for PC Power Supplies Some RepRap electronics are already prepared to be used with PC power supplies units (PSUs).
There you can plug connectors already fitted to the PSU's cables directly into the RepRap board, no modification or opening of the unit required. The picture shows a PC PSU with 20 pin ATX connector into an electronics with ATX24 header as an example. Any combination of ATX20 and ATX24 headers and connectors work. Base Load Many PC PSUs (not all) require a base load on the 5V rail to work properly.
Wether you need a base load or not has to be tried. List of PC-PSU enabled electronics This one is a bit tricky, as some PSUs with identical specifications work better than others. In the RepRap forum you can find a number of power supply experience reports. Wiring the supply There are three types of PC power supply you will commonly encounter. You generally only need to connect a wire from black (ground) and yellow (+12V) to the RepRap.
Color coding Pinouts Steps. Burning the Sanguino Bootloader using Arduino as ISP. Sanguinololu Bootloader Burning Release status: working Burning the Sanguino Bootloader to the ATmega 644P using an Arduino as an ISP.
So you just finished soldering up your Sanguinololu, Gen7 or whatever board and are ready to test it to see if everything is working properly, but before you can upload any firm ware to the board you need to burn a Bootloader to the ATmega 644P. In this tutorial I will cover using an Arduino or Arduino clone as your ISP programmer. Sanguinololu12. Sanguinololu. Sanguinololu Release status: working Introduction Sanguinololu is a low-cost all-in-one electronics solution for Reprap and other CNC devices.
It features an onboard Sanguino clone using the ATMEGA644P though a ATMEGA1284 is easily dropped in. Its four axes are powered by Pololu pin compatible stepper drivers. The board features a developer friendly expansion port supporting I2C, SPI, UART, as well as a few ADC pins. The board is designed to be flexible in the user's power source availability, allowing for an ATX power supply to power the board, or the user can choose to install the voltage regulator kit for use with any power supply 7V-30V. Latest Updates Latest revision: Version 1.3a - Updated July 21, 2011 Version 1.3a has no software changes - the pin assignments remain the same and your 1.2+ compatible firmware should work here fine.
Latest posts in the Forum Features Small design - board is 100mm x 50mm (4" x 2") - barely an inch longer than a business card!
