HackerBot 3D printer has been presented at MakerFaire Rome 2013

hackerbot makerfairerome 1024x768 HackerBot 3D printer has been presented at MakerFaire Rome 2013

After a lot of months of work we are presenting right now the HackerBot at MakerFaire in Rome.

We have put a lot of effort in this printer and we’ve designed to be very versatile and strong. The head can get up to four heads and in this first release we have two bowden extruders (0,5mm and 0,35mm) and one drill.

The structure is all in aluminum with high quality profiles. We got also an heat bed and plexy covers on all the sides. The miss right now is a cover for the upside but we’re working on it.

The speed are quite impressive and the dual extruder works nice. We have done also some experiments on support material (HIPS) dissolved in the tasty lemonene.

Sunday 6 October 2013 we will at the MakerFaire Rome stand as OpenSourceHardware.it and as FabLabPisa and we will be happy to meet you.

 

se ya!

 

 

 

 

 

Opensource hardware Stepper motor driver. Big one.

The design of this stepper motor driver is based on an Allegro A4989 and IRLR024N Mosfet, like the powerlolu stepper driver from Alfred Bauer aka Fluidfred.

Theoretical amperage is 15A peak.. but is there a so big stepper motor?

Design files are on Eagle (freeware version), PCB is 105×80 mm.

The copper traces should be 105um at least, i used DB9 and MSTB connectors and i put the trimpot near the edge of the board. And a led.

I think that would be great to print a case (perhaps with DIN rail mount?) with a 3d printer.

Testing new extruder for RepRap

this is the very first prototype of extruder for geared stepper motor (reduction ratio 1:50)

Yes, it has metal gears and it’s very compact.

I’m going to test it, if you like or wish to test it just contact me

thanks icon wink Testing new extruder for RepRap

arcol 1024x768 Arcol.hu Hyena arrived!wow! @arcol_hu !! great hobbed bar.. very good job Laszlo

so Laszlo will reveal how he does such beautiful hobbing? icon smile Arcol.hu Hyena arrived!

 

 

 

Awesome Ramps 1.4 with 20×4 LCD and SD card

wpid 20130211 233403 Josh Awesome Ramps 1.4 with 20x4 LCD and SD card

I was amazed by the great possibilities of configuration and control of the LCD display.

In addition to show all the standard parameters and the option to change the feed rate is the option to change on the fly acceleration, jerk, maximum speed, the STEP UNIT on the axes, change the temperature, the PID parameters and of course load files to be printed directly from the SD card.

From now on it will be a must on all printers

In this config i’ve used a simple LCD 20×4, a SDCard kit from grrf.de, and an encoder (EC11E15244B2)

Marlin configured with #define NEWPANEL

 

BHead with knurling..

wpid 20130209 220202 BHead with knurling..

i’m testing the new nut with knurling and apart from the aesthetic factor nut is considerably lower thus improve the thermal behavior.

Also the thermal barrier is PEEK and hereafter will be only in PEEK.
