Isel CPM 3020 - run with mach3?

Thanks a bunch!!

So i started taking mine apart tonight, hoping it was going to be an easy wire up.. well this one is using different steppers.. Mine has these installed..

Also for some odd reason the wiring color does not match what the diagrams show :(

ok good news.. i think.. It looks like the 8 wires coming off of the stepper are already bundled together and only 4 wires are coming into the DB9 connection.. the other wires are the limit switches.. I think i might be able to finish wiring this thing up this weekend.. maybe..

Here is the wiring diagram I think it accurate based on the research.. hoping to start wiring it soon.. Don't judge the drawing :(

Ok i'm at the final point, i think..

but I am a little confused, i'm a newbie to setting up my own controller..

The BoB I has (+5V, EN, DIR, and STEP) the Drivers has (Pull + / -, DIR + /-, and ENA + / -)

I know the BoB EN = ENA on the Driver, DIR = DIR + on the driver and STEP = Pull + on the driver.. but what do I do with the extra 5V on the BoB?

Thanks for the help!

Hi guys,

Sorry for the lack of reply Steve. I just came on here to ask a question and saw your message.

I used the existing power supply. I didn’t need to rewire anything. I just chopped the wires (turned off of course!) and then used my multimeter to figure what voltage each of the lines were! I can’t remember what they were exactly but they were good enough for what I needed.

I have to say Steve that although I’ve taken on a few cnc projects I really am wading my way through murky waters! I can’t really help on the stepper wiring but I distinctly remember testing the wires (using s YouTube guide) to figure out which were the pairs. The motors work great for my needs!

Good luck with it, I’ll pop back on here but I’ve also just got your email so do email back if you need anything.

Cheers
Chris

I too, used the existing power supply. It had three different voltages available. Most useful. Similarly to Chris I coupled my 4 wire steppers to the original cabling inside the aluminium stepper covers and then again to my drivers in the control box. The logic is quite simple and straightforward. I am no sparky and was more worried before than after. Just go for it. Think you will find the Isel hardware is well worth preserving.Extremely impressed with the accuracy and repeatability of my 850/1000 machine.

I was able to get the X and Y axis running last night.. I will hopefully have enough time tonight to finish the Z axis.. I'm still not sure on how to setup the micro stepping and the motor velocity in mach3 (cause I don't know what values to use)

Anyway, here it is moving.. https://youtu.be/iSry6ZRe8bI
