Steve ... I am finding it seems one needs to educate them selves thoroughly before buying this CNC gear. Oh well at lest i am learning while wasting a several dollars! FYI i look forward to seeing your new pulsed/MACH4/Ethernet based board in the coming months ... i will be one of your first customers! Comment about your design ... with the MX-4660 4 axis (expandable to 6 axis) driver system it comes with a breakout board built into it ... is there any though to making a version of your new controller with just the port outputs so i can connect directly to the Leadshine board via a ribbon cable (sorry being a bit selfish)? Anyway I am pretty good at LED power supply's but I am a stepper drive idiot so take my suggestion with my knowledge base into consideration.
Anyway back to my system
I will be using 4 Chinese ACT-Motor 23HS2430B to run this machine, they are 425 oz 3A 112mm ... FYI i will be gluing, testing and putting lens on lights, we do 20,000 unit builds at a time so i need speed! I need speed in X,Y,A and both speed and as much power as possible in my Z axis to snap a polycarbonate lens to a heat sink. Again not knowing the proper application for selecting motors these are what i purchased to date.
My plan is to use MACH4 and to customize it with some basic scripting to flip and read some inputs and outputs to run a few air actuated devises and a vacuum pump. I for one have never heard of Lua, but from what i read this language it the cats in the gaming world and for scripting. I hope at my age this old dog can learn it. I sure hope there is some individuals on this form who can give me some direction.
I have a few other questions which i would sure like some one with experience to educate me.
Q1. I notice the wires on these steppers are very small and the peak currents are fairly sized. Should I keep the wire from the stepper very short and connect to it using shielded say 18 gauge 4 conductor wire to the drivers?
Q2 How much is does noise play havoc with these systems? Does one need to add some input capacitance on the output of the supplies?
Q3 Are there much issues with ground loops in these systems?
Q4 Are there any best practices for connecting the various power supplies grounds.
anyway hope i am not out of line for asking so many questions
