So I have everything I need to build the pre-treater, so a few more questions:
1. I'm building the base out of OpenBuilds V-Slot Gantry Set and V-Slot Linear Rail coupled to 1 1/2" PVC Schedule 40 pipe. I will T the pipe to build the riser extensions but wonder where I should place those extensions in relation to the the V-Slot which is 39" long. I'll be using/making a platen that is 18" wide and 24" long.
2. The Start and Purge buttons. Does the polarity matter when connecting to the Pre-treater board?
3. bStop = Limit Switch?
4. Length and Speed buttons. With the buttons facing with the terminals up, from left to right, would that be minus, ground, plus?
