Well I am starting the build of my control box. I have been simulating this circuit and it looks good. Here's the pic
The pump below is based on the Mariss’s circuit at http://www.artofcnc.ca/ChargePumpSafety.pdf. The circuit turns off in 1 millisecond, but it is turn on delayed 4 milliseconds in order to avoid a false triggering. It has spindle on/off control and three limit switches pairs that shuts down de geckos supply when are activated.Update 07-26-2007
