i think it's possible to melt the tip of a metal wire with a high current and 'dip' the tip, so a droplet will add to the fabbed object - but the handling and uniformity of the placed volumes isn't so trivial. So try first with simpler/common methods and when this works, evolve further Viktorby VDX - General

Hi unfold, i think it's simply the wrong way from G-code back to the 3D-visialisation. Normally you have your 3D-object in the CAD programm which you can change, optimize and so on ... and when ready, the exporter generates the slices and/or paths for your reprap or mill. I sometimes reimport toolpaths back into my CAD/CAM for refining or adding some extras or simply reviewing, but then it's aby VDX - RepRap Host

Hi Vik, ... i've developed some actuating/driving methods scalable down to submicron dimensions - the most interesting is simply a surface with embedded shear aligned fibres (e.g. carbon nanotubes ), pressed on the counter-surface of the object to move and applying (two sorts of) mechanical oszillation. - the first 'coarse' (or longitudinal) mode is simply with linear oszillating the surfaces,by VDX - New Zealand RepRap User Group
... i'm thinking about a fold-out frame embedded in a suitcase - so it's highly mobile and can be stored everywere if not in use ... Maybe it's not so practicable for the standard-reprap, but my setup works with paste-dispensers for roomtemp fabbing and a diode-laser for laminating objects. Another point for a smaller frame is my special interest in high accuracy fabbing with <0.01mm resoluby VDX - Mechanics

Hi LS, ... die Lautstärke ist bedingt durch die Motoren, Geschwindigkeiten und Resonanzen im Gestänge.

... normal 3 pin RC modules have VCC, GND and PWM - you connect VCC and GND to the corresponding pins (or maybe better to a separate power-source). The PWM-pin of the RC module will be connected to a PWM output of the Arduino/Sanguino (with a separate PS you have to connect GND of the PS/module and the chip too). The PWM circuit in the RC module selects the direction of the servo by the pulse-rby VDX - Controllers
Hi Julie, have you tried with VirtualBox ( ) and a Linux- or Windows-client? They're supporting USB/RS232 and you can test with the 'iconoclastics' I'm running with a Vista-Host and Linux/Win2K/WinXP-clients for older CAD/CAM's and some special problems ... Viktorby VDX - RepRap Host
Hi Michael, ... as i understand, you have to exchange the "set HIGH" and "set LOW" lines. With "*step_output_reg[...] |= step_bitmask[...];" you set the corresponding step-pin to HIGH and with "*step_output_reg[...] &= ~step_bitmask[...];" to LOW. So you have to search every occurance of this expression and exchange "... |= ..." with "... &= ~..." and vice versa. For the first initialby VDX - RepRap Host
Hi Michael, ... maybe it's something like "*step_output_reg |= step_bitmask;" where instead of "AND" with an inverted value it should be "OR" with the bitset for staying HIGH. Look in the handling of bit-values and especially the operators "&" (AND), "|" (OR) and "~" (maybe INVERT) ... Viktorby VDX - RepRap Host
Hi Michael, the running software only inverts the step-pins on every occurance, so you have to initialise the pins at startup to HIGH and when stopping set them to HIGH again instaed of LOW as now. I don't have the arduino-IDE here, so out from memory: - somewhere in the end of the stepper-controller.pde you have to set the pins to LOW by something like "step_pin[] &= ~step" or such for eveby VDX - RepRap Host

Hi Michael, which version do you have? In all my versions in the function "do_step(byte step_pin)" you can invert the stepping polarity by exchanging HIGH v. LOW (a.v.v.) in the lines "digitalWrite(step_pin, HIGH)" and "digitalWrite(step_pin, LOW)" Viktorby VDX - RepRap Host
... a magnetic 'levitation' setup is not rigid enough for a cartesian bot. I developed some micropositioning stages with magnets and ferrofluid as linear stages and actuators - it's friction free and highly precise until nanometer resolution, but you need a position measuring feedback in the same accuracy and the behaviour is like a strong damping squid.
