Isel CPM 3020 - run with mach3?

Feedback:
digital drives cwd556
cant afford ip-m so have gone for KK01 BOB
will upgrade to ESS next pay day but will get it moving on this.

power supply - currently using the 29v supply after learning how to get it all back together again. This will be upgraded to a new cap and transformer for a bigger supply when I can afford it.

Currently the machine is running and I'm pleased I've got this far. I'd like to wire up the limits and home then it's on to spending money for motion control and supply.

Information regarding homing was off YouTube, move vids seem to home to the centre.

Im still confused by home switches. I don't see why you need a home and you can't just hit the limit switches as a corner home. Or even hit the limit switches for position and then find a software based home. I must be missing something. Also, most people seem to home to the centre of the bed. What is the best way to mount these switches and have them triggered as I guess they will mechanically get triggered a lot when the machine is actually in action?

On a full size 'proper' cnc machine the limit switches will lock out the controller until someone with nouce can determine if it is safe to re-set them.

Remember you are playing with tiddly little stuff, but a full size machine can have several kilowatts of axis drive power that can shift things pretty fast and do very much damage.

On my Beaver Partsmaster the previous owner screwed up the Y limit switch setting, and it had managed to destroy a VERY expensive 40 mm ball screw and nut - if only those students hadn't fiddled ! (ex Bristol University)

On my Traub lathe the mass of the tool turret and slide mechanism is huge with servo drives of commensurate size - you don't mess with the limits on those unless you have very deep pockets http://madmodder.net/Smileys/default/confused0068.gif

Good practise dictate that you have separate limit and home switches

The cnc machine is now up and running. I`m blown away with how fast and how accurate it is and how well it did with a 4mm cut depth in brass cutting some text.

It has no motion control on it yet and just the 25v supply.

Hi Chris,

I hace buy a ISEL CPM 4030 this week without software.
Looking how I can use the CNC I found your topic, very interesting.

Can you send me more details about what you changed on the Milling machine to let it work?

Saturday I get the CNC and I can look the internal components.

Regards,
Philippe

did you wire the 8 wire motors b polar parallel

I have a full licenced copy of the KAY software for sale including the instruction manual. This will enable you to feed the machine from most any Cam system with an "Isel" post processor. E.g. Fusion 360, Estlecam etc.
Let me know if you would be interested

some one made me a pair of 65mm motor mounts for mine, he is on here

you can get mini vfd's now

it might quieten it down from 90 db to 65
plus you won't have to have the door open to switch yours on

Hi,

I have test the Kay (demo-version) and it's working, It dhould be nice to have a full version.
I'm interested into your offer.

Regard,
Philippe

Hi very interesting, I bought the day before yesterday a CPM - 3018 from a place in Harwarden for a offer of £100 plan on using a elderly PC i have in shed and https://charter-controls.com/product...rollers/g251x/ drives no idea what breakout board as PC dose not have a pparallel port

when i get it home tomorrow i will run a demo software on it to ensure it moves, dont see why not it seems to have had little use

Attachment 22452
Attachment 22453

Still have the licenced Kay software if of any interest?

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

Hi

cant remember what parts i used for mine i will have a look in sunday when im back in workshop and let you know

Steev

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 :(

Attachment 24427

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

Attachment 24432

Well I got everything wired up as far as limit switches and motors / drivers go.. everything moves and stop when a limit switch is touched..

tonight ill be installing the relay (router control) and maybe make the first chips..

Well I'm all done with this conversion..

https://youtu.be/sR1u89dEdgc

Thanks for helping!

Hello do you still have kay soft + licence?
Br.Dariosh

Sorry - Sold some time ago.

Well I thought I was done, but it seems like the microstepping I have set aren't working right.. This is also going to be a pain since the lead screw is in metric, but we use imperial on this side of the pond..

Anywho.. I thought I had everything configured properly, but the x axis keeps skipping a step randomly..

Attachment 24474

Are you sure all vectors are connected/joined together?

Phill

I am interested to buy license for kay cnc. Br : Dariosh

The picture appears to show Stepper Online DM542Ts.

https://www.omc-stepperonline.com/di...or-dm542t.html

I have the GALAAD license so i don't know i must test if the original board on the machine it move fast enough, if is slow version, then i will update to mach3, i wait for the USB to rs232 adapter to come, to do some tests

Steppers motors are STP-57D13-01 1.8 DEG/STEP 2.5V 3.0A

Hi guys,
the subject is a little dated, but I am looking for information and especially help.
I just bought an ICP4030, same machine but bigger and more resent.
I want to do the exact same retrofit : UC400ETH + BOB + UCCNC

I am looking for information on how to wire the machine
Someone to help me ?
@mchipser ?
@Steve-m ?

Thks !!

Don't do any modifications, it works fine, i use mine with galaad and old desktop with serial port. All you do you make the design on any pc and you load and run the file from older pc with serial port connected to the machine, there is a schematic in pdf for whole pcb, if you google it, you will find it, check images and all when you google, like search type all, and images

Thks MarMix, but i'll do it.
I don't have Galaad, and I would rather pay for a UCCNC license than Galaad.
I have the pdf of the pcb, but it does not bring me anything.
I'm looking for how to identify the wires that go from the Nema to the drivers.
