Having referenced the spindle head, it can then be moved to the WCS zero ready to run a job. I turned an eccentric ‘top hot’ to fit on this screw to activate the microswitch.įitting the switches has now made setting up more repeatable and it consistently goes to 0,0,0 when doing a Reference All. There was a protruding M3 screw holding the interface connector in place which was acting as a crude carriage stop. I slipped up with the +Y back stop switch in that I mounted it on the cross plate without realising that the interface cabling to the umbilical connector fouls the movement. I had to add extra wiring to the cable forms both on the machine, through the connector cable to the control box and inside the control box. I made 3D printed mountings for the switches and covers for these. (Mach3 just looks for a break in the circuit relevant to the function being asked of it – it knows when it is homing and it knows when it is running and looking for a switch break). The same switches also perform the home reference function. Any switch when activated will now break the loop and create an alarm condition. I connected one end of the loop to the Input 2 terminal on the card terminal strip (Port 3) and the other end to ground. I fitted 6 microswitches and wired them in series via their normally closed contacts to create a loop. Having been used to homing the Tormach I decided that adding limit switches to the 3040 would be a good thing. If anyone needs screen shots of these setups send me a message. I had to make changes to the Mach3 Config for this. Once this was sorted the motors responded to keyboard directional commands with the arrow keys and page up/down.

The first problem was the RnR USB interface card and trying to work out which port was which on the card connections. As a result of this Mach3 does take a bit more getting your head around and there is a lot more under the hood settings and adjustments that you have to address. Mach3 is not like PathPilot but then it is an all things to all machines software whereas PathPilot is dedicated to the Tormach family. Progress has been good in getting the 3040T running.
