Xylotex vs Probotics

[PsychoPig7]

Hi all
Does anyone out there have any thoughts about comparisons between Xylotex and probotics 269oz/in kits? Are they both comparable products, and/or what about reliability etc?
Cheers

After taking a quick look these are my thoughts,

Comparing the Xylotex 3 axis kit with 269 oz steppers, driver board and power supply $309

And Probotix 3 axis kit with 260 oz motors, three drivers, break out board and power supply. $310 + $20

Motors are much the same in both kits as are the power supplies.

Drivers are similar specs. Probotiix is three separate driver boards and Xylotex all in one.

Probotix for an extra $20 comes with a good isolated Break out Board. Xylotex does not.

Personally I would look further a field but for the money these are adequate options.

Have you thought about what size motors you need?

Greg, thanks for the quick response re: Xylotec vs probotics.
I am starting to build a router loosely based on the K2 design - but with several variations. I want to be able to cut both timber and aluminium. The x-axis will be about 1000mm, while the y-Axis is about 850mm. Still thinking about the z-axis but will probably stick to about 200mm. I am also looking at the 57hs hybrid stepping motors and m542 drivers from Leadshine/Ocean controls. These motors are rated at 311oz/in.
Cheers

If you are looking at Nema23 motors, most of them are 3amp.

I would seriously look at this new Gecko offering,

Thanks Greg - the 57hs stepper that I was looking at is the 8 lead, 57hs22 and according to the spec sheet it is rated at 5.7amps when wired in Bipolar parallel.
Another silly question - if i wanted to run three such motors rated at (5.7ampsx3) how big a power supply would I need?

[Greolt]

Probably need to run them in series. Unless you are going for big drives

A better choice might be,

KL23H2100-30-4B 382 oz-in $44

More oz/inch, less amps, slightly less inductance.
