“This is a custom solder paste dispensing head that can be added on an existing CNC machine. The CNC machine, for which the dispensing head is currently developed, is a FABtotum multipurpose device (https://opentotum.github.io/fabtotum.com-backup/):
CAD files for dispensing head come from a remix of TwinTeeth’s dispensing head (http://www.diyouware.com/node/174), adapted onFABtotum carriage.A remix of CAM software rpt2pnp (https://github.com/hzeller/rpt2pnp) was adapted to fit the needs of FABtotum supported gcode commands.The PCB on which tests were made is an FTDI circuit (http://archive.fabacademy.org/2016/fablabsingapore/students/98/exercise06.html) designed with KiCAD (1206 Imperial).The PCB is milled with FABtotum using FlatCAM. An 20G 0.6mm ID 1.5” dispensing needle is used to dispense diluted solder paste with IPA.”
