Xylotex vs. Stepperworld?

[kayakman]

Hi you all

I have had a little break in my homecnc prodject. Now I have to decide for which controller to use.

The candidates are!! Drums please!!

STEPPERWORLD SPECIAL $219 Complete System!
Model SP-3/HT (Hi Torque/Hi Top-speed)
Complete 3 Axis Stepper System

and

Xylotex XS-3525/8S-3 Stepper Motor Driver Board

It seems to me as the STepperWorld package is a tasty deal.

Does anyone have any information that can help me choose??

The electronics is to be used on the following prodject:

Hi Kayakman!

I looked at the Stepperworld Site it looks great, three nice steppers and driver just ~200 USD.

I also have looked at the Zoltar site and his links to a couple of German sites with very good drivers, Ok they are more expensive but I think they are very reliable, check Odin it is just so...

Another way to go is to buy Conrad SMC1500 with or without the option card, if you buy it without the option card, the cheap Lewetz software for Conrad hardware is just very nice, easy to understand and to manage.

BTW can you please give us more pic's from your work with the Zoltar clone.

I am not sure that the stepperworld driver is a true chopper board, or uses resistors.
I have the xylotex board, and I would not consider anything else. I get 46 IPM on 24V with 1/4-20 threaded rod as leadscrews. It generates very little heat, and runs the steppers smoooooth.

Kayakman,
From the other thread it looked like you were going to use acme screws "trapesgjänga". Did you check with ww.Solectro.se and ask them for their price on rolled ballscrews? It's not bad at all. I think close to 1K5 SEK.

These are low quality screws from Isel with radial adjustment of backlash. But still they do have the benefit of very high (around 90%) efficiency. This has the effect of doubling (more if you plan on acme with backlash elimination) the power of your motors and drive electronics. So you will easily save the extra cost of the ballscrews when you buy motors, drives and power supply!

To yukonho:

What is the difference between a true chopper board and one that isn't? I saw that the Stepper world driver was built to drive unipolar steppers and the Xylotex is built to drive bipolar. Is bipolar better then unipolar?

The Xylotex seeem very tasty with double stack 23 size steppers. The Guy at simply cnc who is Xylotex retailer in europe say that my kachine was very odd and large and he didn't want to give me any recomendation due to the fact that he wasn't used to this kind of router machines. He recomended me to get advice from other users like you guys.
The Machine has a table of 1300x800 mm and is to be used mainly to cut rc model parts in wood, plastic, plywood and sometimes in aluminium. I kno wthat a machine of this size will raquire quit large stuff if you want to get realy good speed but I can settle for medium good speed : )

Does anyone have any advice. Am I right when I'm thinking that Xylotex is the way to go?

To Esjavik:

I just surfed in at the Solectro website and they looks great. I have to do some thinking and then call them to get a price.


Please help me someone : ))

I just send my money order for the Xylotex driver. should be here some where next week

kayakman, I'm hesitant to offer much advice because this isn't my strength. But since you haven't gotten many responses, I'll tell you what I know (or think I know).

I own two Xylotex boards. They have the ability to microstep 8 steps per revolution. The Stepperworld is only capable of half stepping. This is supposed to translate into a smoother running machine. I think that this has something to do with the chopper feature.

The Xylotex is rated at 2.5 amps per motor and the Stepper world SP card is 1.25 amps. This means that the Xylotex can run more powerful motors.

I read somewhere that bipolar is better than unipolar, but I cannot remember why.

Search in this forum for Balsaman's 1st router. He used the heavier duty FT-3 cruiser and was very happy with the performance.

I feel that for your size of router, the Stepperworld package with the 80 ox motors is too small. The Xylotex should be your minimum size. (amps) and you might want to look at something larger.

I personally haven't used the Stepperworld product and cannot confirm its performance. The Xylotex works well when hooked up properly, but for an electronic novice like myself, it was incredibly easy to do things wrong and damage the cards. I found the directions confusing, but on this forum, someone made up some simple directions and I recommend following them.

Good luck

I have both boards. You might want to decide what motors you are going to buy first. If you get unipolar stepper motors, go with the NEW board from hobbycnc.com. If you get bipolar motors, go with the xylotex board. I used the stepperworld SP-3/HT system and was not happy at all.

The chopper (pwm) will only allow the set amps to the motor. This will allow you to run the motors at a higher voltage with out harm (aprox. 10-15 times the rated voltage) to the motor. You can use 12V computer power supply on ethier. For best use you should try to locate a 24v power supply (harder to find than motors or driver boards).

You might want to also look at the new hobbycnc chopper board. 3a and 44V, along with microstepping too. I just saw this, and don't now much about it. http://www.hobbycnc.com

Xylotex. Don't even consider the spht.

I have the Xylotex and had absolutly no problems with it. If you can read a picture book then you can wire this thing up. If you get confused there are always plenty of people to ask.

[kayakman]

I think that I will go with the Xylotex controller. Anyone have a suggestion on which size on the bipolar stepper motors I should use to get reasonable speed with the Xylotex controller and also what power source that should be used. Will any 24 Volt source that can give ?? amps do the job?
