Isel CPM 3020 - run with mach3?

**Steve-m** · 03-08-2017

Thank you may be of interest please pm me with a price, may help me to decide which way to go

Steve - I would think about £50 for disk, +licence + spiral bound manual. Works very well. You would certainly not want to pay what I paid for it!!!

No that was one of the reasons I was going other way, for not much more money I had a updated machine with up to date software I already have mach3, leave it with me and get back to you, may be a idea while I collect bits, unfortunately I don't have home until tomorrow to see if it even moves

HI Chris
Im modifying a simalar machine using all the same bits as you CHD556, a KK01 Bob, and a UC100 Motion control, PLEASE can you help with some pointers on some of your wiring of existing bits,

1/ how did you rewire the 8 wire stepper motors?

2/ what did you do with existing PSU how did you wire that?

Thank you

First let me say I know this is an old thread, but I just received the same CNC and was also wanting to do a mach3 conversion.. Gleaning from the previous post it looks like I can reuse the stepper motors and just need to replace the drivers and PSU, then a motion controller..

I ordered everything I think I need to get it done..

Shopping list:
x3 STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-step Resolutions for Nema 17, 23, 24 and 34 Stepper Motor
x1 LETOUR DC Power Supply 36V 350W AC 110V Voltage Converter DC 36V Adapter Aluminum Shell LED Power Supplies for Visual Doorbell, Brake Machine, Electric Driver (Silver) DC 36V 9.7A POWER SUPPLY
x1 SainSmart 5 Axis Breakout Board for Stepper Motor Driver CNC Mill
x1 C2G/Cables to Go 10338 DB25 Female Parallel Add-A-Port Adapter Cable with Bracket (11 Inch)

I already have a ESS (Ethernet Smooth Stepper) to use from a previous build..

Is there anything else you can think of?

Also to Steve-m, if you haven't figured out how to wire the motors I think they should be wired like the attached photo (please confirm if I am wrong).. this is based on the pdf here

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 :(
