Incredible 6 parts CNC plotter


Jay made the smallest CNC plotter made by Laser cut parts which according to his blog cost about $20 to re-produce, this is really amazing piece of engineering:

I do wonder if something similar could be adapted for solder paste syringe and to make small solder paste spit machine which to eliminate the need for stencils for prototype runs.

    One quick clarification – the parts all are 3D printed. 🙂

      thanks for the note! yes, I see these sliders are done with 3D printer, but probably could be done with two laser cut parts screwed together too 🙂

    Various X-Y-Z movements can be made in many extremely low-cost and simple ways. The problem with all of them is that unless one starts spending extremely _much_ money instead on the movement, their severely low precision makes them unsuitable for any actual work of any kind.

    That applies even more stringently in PCB-related work, where even the simpler store-bought hobby CNCs with precision linear bearings and ball screws may struggle to achieve usable SMD-level performance (I’m using one). I would expect a solder paste dispenser to have a similar level of requirements unfortunately – far, far out of reach of anything one can 3D-print. Even “self-replicating” 3D printers use printed parts as structural elements only, to hold the frame together: their movements are usually also precision rods and bearings.

    One way around that are the recently-becoming-popular delta-bots that have no linear movement at all – their catch is that the ball joints they use have to be equally (in not more…) precise; unfortunately, I have no idea how expensive such ball joints are.

      this is why I’m interested to see what will happen with metal laser cut parts done with less clearances than 3D printed parts
      solder paste usually dispenses drop at pad which is bigger and slight offset not in middle will be not problem as the paste have joining forces when heated and will come back to the pad even if disposed slightly off the pad

    Well, part of my goal here was to make the actual ‘bot dead simple for dirt cheap – even if that means sacrificing quality.

    Can somebody make a set of parts for me. I do not have a 3D printer.
