Introduction

RepRap Arduino Mega Pololu Shield, ou RAMPS pour faire court. Elle est conçue pour fournir toute l'électronique nécessaire au fonctionnement d'une RepRap avec un faible encombrement et un prix bas. La RAMPS s'interface sur la carte la plus puissante disponible chez Arduino (NDT : proposition à confirmer), l'arduino MEGA, qui dispose de nombreux emplacements d'extension. Le module embarque le driver pas à pas et le controlleur de l'extrudeur sur un Arduino MEGA "shield" pour faciliter la maintenance, le remplacement de composants, la possibilité d'upgrade et d'ajouts de nouvelles fonctions. De plus, plusieurs extensions Arduino peuvent être ajoutées du moment que le module principal RAMPS reste le module principal et soit placé "en haut" (NDT : hiérarchiquement) des autres.


La version 1.4 est constituée de condensateurs et résistances montés en surface (CMS ou SMD en anglais) afin de faciliter la mise en place d'un couvercle ou son intégration dans une boîte. Tout comme la version 1.3 afin de contenir plus de choses, la RAMPS n'est plus conçue pour être facilement gravée à la maison. Si vous voulez graver votre propre carte choisissez plutôt la version 1.25 ou la Carte Generation 7. En effet, les versions 1.25 et précédentes sont des cartes dessinées en "1,5 couches" (c'est à dire que c'est une carte double face dont un côté peut facilement être remplacée en soudant des fils souples) que l'on peut graver sur une RepRap ou imprimer par la méthode classique de transfert par toner.

Cette carte est majoritairement basée sur le projet Electronique Pololu d'Adrian et le travail effectué par Tonok. Copper etch resists methods suggested by Vik. Également inspiré par le travail de Vik avec EasyDrivers. La conception du circuit est principalement basée sur le modèle Electronique Pololu d'Adrian. Joaz de RepRapSource.com a fourni la définition initiale des broches et de nombreuses améliorations de conception. Ainsi l’inspiration, les suggestions et les idées de Prusajr, Kliment, Maxbots, Rick, et beaucoup d'autres dans la communauté RepRap.

Versions Personnalisées

Grogyans

Will have locking connectors for the motors. Uses the MAX6675 thermocouple sensor, which essentially replaces the AD595. Less vias, which should also increase building time. Bottom only, to enable the possibility of a RepRap or toner transfer method to fabricate the board. Moved the power LED to the front for easy identification. Providing the user has a proto-shield for Mega, there is plenty of pins left for them to play with. By using another tiered board, will alow the possibility of more extruders and LCD all of which can communicate over the I2C protocol.

Dépannage

  • Check List
  1. RAMPS shield firmly seated on Arduino MEGA
  2. No stray wires/metal to cause short
  3. All connections firmly seated, screws tight
  4. Power connection oriented correctly, connected to RAMPS shield (only USB is connected to MEGA)
  5. Thermistor connected to T0
  6. Firmware uploaded
  7. Stepper driver potentiometers to a sane setting (maybe 25% from CCW to start, adjust to enough power to drive axis + not overheat)
  8. Heater wires properly connected
  • Cannot connect?
    • Verify firmware and host software baud rate matches
    • Disconnect USB, reconnect, and retry
    • It may be a problem with the software you're using (repsnapper). Try using pronterface.
  • Stepper motor getting too hot?
    • Adjust the potentiometer (small screw) on the stepper driver in question by rotating the screw counterclockwise to decrease the current going to the stepper motor.
  • My fan is not working.
    • If you have RAMPs 1.3+ and sprinter firmware (set with the default pins for RAMPs 1.3), try attaching the fan to D9 output.
    • In pronterface, the fan can be turned on by using the M106 command and turned off with M107.

Stepper Driver Testing

If you are not sure whether you have a problem with your RAMPS or the stepper drivers you can test that the driver is getting the power and signals it needs to work.

  • Stepper motors getting too hot?
    • Adjust the potentiometer (small screw) on the stepper driver by rotating the screw counterclockwise to decrease the current going to the stepper motor.

Use a meter of some sort to test the signals at one of the motor drivers. Be careful not to short anything out. You can use a (-) pad in AUX-1 for ground and test the voltage on VMOT, VDD, EN, STEP, and DIR. If all of these are working correctly then the stepper driver is likely bad.

Question & Réponse

  • What power supply you recommend for your ramps board. I have just finished assembly and looking at the diagrams for a pc power supply and wondering about the separate amperages for the extruder and heated bed. Can they be higher amps without damage?

Yes, the power supply being capable of more amps than required is the desired configuration. The current shown are the max supported by RAMPS and is the minimum the power supply should be capable of. It is also OK to have both of the inputs on RAMPS connected to one PSU with enough capacity. If you are not using a heated bed the entire thing can run off the 5A side (D8 will just not work).

  • I got a RAMPS V1.3 as part of a kit, but it doesn't have any installation instructions - just a schematic. Can you point us to a good tutorial for connecting everything? (i.e. stepper motors, opto flag pcb's, power, data, etc) Some of it (like the single USB port) is obvious, but some of it isn't.

See RAMPS1.3 for instructions for version 1.3. There is a version navigation bar at the top of the RAMPS pages that allow you to jump to a specific versions instructions. There is a very helpful graphic under Final Check section.

  • For RAMPS V1.3 the power section of the schematic shows several places with GND/12V (C4/C6, X4-2/1, X4-4/3, VCC/D12). Which one is the GND/12V from the power supply? Is it the round power plug like a laptop power plug? Also, is the outside of that plug GND while the inside is +12V? My kit came with a note warning not to reverse the input power or it would cook the board . . . and a plug adapter with no labels that can be installed either way.

See the connecting power section of your version's page. The round plug is on the Arduino MEGA and will only power the MEGA. You need to power the green pluggable connector, it should not be reversible and the board should be marked (+) and (-). If for some reason your board is not marked you can follow the diagrams and pictures in the wiki.
