i purchased a 1999 model router with the aniheim 1/2 steppers and dos controller a couple of years ago, i was advised an did replace the drives and motors to keling, i went with the wincnc but mach 3 will work just fine, initially i used the keling drivers ( i liked the switching for power ) but have recently switched further to the gecko 201's they are smoother and i would recommend you do this for the same reason i did, " you will eventually have to do this" it was well worth it and now the reliability of that router is the last thing on my mind

Hey Jim
Good to see you are still taking care of me ,Thanks to all of you.
Is there a big difference between the gecko 201 drives and the 540, that includes 4 of the 250 drives?
I was hoping to get the completed control box from keling that includes the 540, a power supply. e-stop, on-off switch, all mounted in a box. They have it for sale for a little less than $500.00 US. Doesn't include the stepper motors but I was hoping to use the ones that are currently on the router, they seem to be nema 23's and have d9 connectors. If they don't work then I will buy new steppers. I know nothing about electronics and don't want to blow anything up and have to re-buy for the sake of saving a few bucks. Also I want to keep this as simple as possible.
What do you guys think? Am I on the right track?
:cheers: Ted

the nema 23s on the techno will work do they have a model number, you will need to know what wire is what phase. sounds difficult it isn't!! look for model number we can get specs from that. i am a fan of the 201's and basically because i have a few and they are smooth!! gecko has a forum here on cnc zone and marris (gecko) responds to it, he can tell you better than i call gecko as well they are very helpfull! i have also used keling and john is pretty knowledgable as well

Jim: there are a bunch of numbers off the steppers on post # 5 of this thread. Are one of these the model number? Or do I have to look further?

yes first it is a 2.4 amp motor i will see if we can find the wiring diagram

Zweiphasen-Schrittmotor 1.8
Art.-Nr.3460

Iw = 2.4 A Rw = 1.0 ohm

this has been discussed here before,

do not disconect your existing motors or drivers with out first photographing the wiring

if you can show us the wiring coming out of the motor and the wiring at the driver

we can tell a lot from that

Thanks Jim.
Will take pictures but can't till Monday. Have a good weekend.

This uses 9 pin connectors on the cable from the control box to the motors.

Its pretty cool that you have all of the wiring done for you! It looks like a unipolar motor wired in bipolar. You should take a resistance meter, or a DMM to the wires to find out which wires are paired up to the coils. Once you find out which wires go to the same coil in the motor, you can connect them to a gecko drive or some other drive.

You know how much current they can take so it should be easy to configure the motor controller!

[Tsooko]

Hi all
Aaahh, Good news.
At the risk of seeming a total nob, I have some questions. Which wires do I test as pairs and what readings am I looking for? What do you mean by unipolar and bipolar? Which is better?
So these steppers can be used with a different control box than the M-100 techno box I now have, means I won't have to buy new motors at lease for now.
On the gecko thread most guys have recommended the 203's for drivers. They are 201's that have been improved and seem to be bullet proof. They will run the nema 23's and can be used to run nema 34's if I have to upgrade. What do you think?
If I get these, it looks like I will have to build a box. Is that hard to do? Perhaps Keling will build me a box with the 203"s. I'll have to call them.

From being a Sholtz ( Hogan's Hero's, "I know nothing") I think I'm begining to catch on a little. Thanks!

You want to test the wires that are paired up in a row on the top of the motors. You are looking for low resistance between pairs of wires. If you have low resistance between two sets of wires that means that they are connected to the same coil. My DMM has a loud high pitched tone when the resistance is below 100 Ohms. I think, and this is a guess, that the resistance would be around 6 Ohms if you have the right pairs of wires. There should be an outrageously large amount of resistance if the paired wires are not connected to the same coil.

Bipolar and unipolar are just two diferent ways stepper motors can be driven. Bipolar, I think, is the better of the two. It produces more torque from the same motor. All gecko drives are bipolar.

I would choose the gecko 540, as it would simplify wiring. It has all of the cool features that the larger geckos have without the cost. Also it is more appropriate for your low current steppers.

With a 540 would be simple. Purchase a seven amp power supply that is just under 50 volts (48 would be perfect) Follow the wiring directions included with the gecko drive. Mount it all on a board or piece of sheet metal. With the 540 I don't think you would need a box!

pplug has the right idea, i would have thought that the wiring on the top shaft would have been to a servo, on mine the wires come out of the motor

Yea Bipolar will get the most torque with the smallest package. But he is also using round stepper motors so they arnt as powerful as the square motors.

Its no problem anyway.

Sorry to butt in on your thread Tsooko but I am just curious what are the 3 additional wires for? Are they for limit switches?

[Tsooko]

what are the 3 additional wires for? Are they for limit switches?

Hey bluy^ray.
Being a newbie I can't tell you the answer, good question, anyone else know?

After scoping out some of the other threads here on the techno machines I am begining to wonder if some of my comm port problems aren't related to a cable problem? Seems that one fellow got a used machine that someone had changed the comm port cable on and got one that was not "straight". After changing to a straight cable his "no communication " went away. Hmmm? The computer I got with the table was at a shop to be repaired, just maybe they changed it. I tried a second cable but perhaps it wasn't "straight" either. I wasn't going to mess with this part of the table any more but cables are only about $8.00. Well back to Memory Express, my computer geek store.

I am putting on a demo for RC model aiplanes this weekend as a part of our fall fair celibrations, so next week.

In the mean time I have decided to go with the gecko 540 drives built into a box by Keling, and may even get new steppers with it, Mach3 control software from Bobcad as they will make sure it will meld with the bobcad23 and bobart software I got from them earlier. Should about do me.

Oh yeah! I took in the bobart webinar they put on yesterday morning... in my opinion they do a great job on these presentations. This one was a little over my head ( preditor editor) but the others I attended were good. You can watch them for free from their website in the support section.

I also ordered the" Cnc Cookbook" from Amazon, the one advertsed here on cnc zone. It explains a little about "g" code and other things a newbie should know. 'nuff for now!

:cheers: Ted

[Tsooko]

Been a bit of time. The RC plane demo went well. Lots of people went through. We were using the curling rink to fly our indoor planes and a couple of boys I helped to learn to fly brought their planes and flew them all day. Gave me time to go and get some cotton candy....yummm.
I guess that will give you a clue to some of the things I plan to cut with the cnc.

Hey Blue^ray, I got the tech manual from Techno for the m100 and it shows that the three wires are for limit switches. They are wired to pins 5, 8, 9, on the DB9 connector.

These motors are wired in bipolar parallel mode. I also checked to see if the wires in the connector cable were straight, they were/are. Thanks for the manual Techno!! So that's it for the old stuff!!!

Got the money for the 540 Gecko drive so will order it this week. Here are my thoughts on that: The old teckno box has a power supply in it already, so after I check it out I plan to gut the box keeping the on ,off switch, the emergency switch, the power supply, the connectors and of course the box... put in the 540 gecko drive and wire it all up. the techno power supply may only be 24 volts max but the gecko is rated for between 18 and 50 volts so it should work. Any thoughts on that anyone ???(group). Then after I get Mack3 it should work:banana::banana::banana:

Oh yeah! I ordered "The CNC Cookbook" from Amazon, you know the one advertized here on CNC Zone by E Hess,....Worth every cent I spent and time I waited. Aimed at new guys like me, it explains what all the parts of the cnc machine are, in an easy to understand and not too technical way and he even throws in a little humor. I have only read 9 chapters so far and have found it is also geared to the guy who might be looking at building his own machine, recommened by me. Enuff for now.

I have retorfitted 8 or 9 techno systems both stepper and servos. All for use with Mach3 . I haven't read all of the post but techo uses a fairly consistent wiring scheme.
On the DB9
Pin 1 is phase 1A
Pin 2 is phas e 1B
Pin 3 is phase 2A
pin 4 is phase 2B
pin 5 limit switch normally closed
pin 9 is limit switch common

I think the G540 would be fine for your system. I make a nice case machjined for the G540 or the G201 and also for the G203. Check out my web site at www.camtronics-cnc.com look at the stepper components.

To use the existing DB-9 connector you will need to make an adapter if used with the G540. If interested I can provide the pin out for the G540

Hey Dan:
Nice boxes. I ordered the g 540 from another place before I got your post. Too bad, your price is better by a small amount. Nice website. I'll have to see how things go when I get the gecko. We may yet do some deals. ( I like the scanner)
I am interested in the pin layout.
Your wireing description matches what is in the Techno manual, so I just need to know which motor wire goes to which pin on the Gecko. For now I am going to see if I can use the m-100 box, and I still need to buy the mach3 software. So it will be a little while longer yet. Waiting is a *****.
Thx for your help.

:cheers: Ted

[dmauch]

Thats easy take the two wires that are on pin1 of the stepper and connect them to pin 6 of the db9 that goes to the G540.
Pin2 goes to the db9 pin 7 of the gecko
pin 3 goes to the db9 pin 8 of the gecko
pin 4 goes to db9 pin 9 of the gecko
Use the gecko pin 1 and 4 for your current setting resistor.
Pin 2 and 3 are not used on the gecko db9
But you will need to run the Ground on the stepper motor (5) side fro the limit switch and connect that to thepower supply ground. Last connect the limit switch output pin 9 of the techno to terminal 1 of the G540 for the X axis, terminal 2 for the Y axis and terminal 3 for the Z axis

Thanks Dan:
The gecko has been shipped. I'm hoping it will be here by the end of this week as long as it doesn't get hung up in customs. So sooooooon!

:cheers: Ted

A little update: Got mach 3 today and the g540 should be here any day now. It is out of customs. and on it's way :banana::banana::banana:

Dan: What size resisters and what do they do?

Thanks :cheers: Ted
