 ;D finally some sucess.
i re-installed it on top of its self and got the same result of nothing working.
i then tried the driver test again and got the same.
then i tried just clicking on the driver files to see where they were in the properties section and couldnt see anything out of order, while rerunning the driver test between each driver file i tried. the driver test kicked into life after i looked at the "specialdriver.exe" file. dont know if that is what brought it to life and i dont really care because i have full movement in all 3 axis's and at a much better rate than i expected. i am getting around 3000mm/min out of x and y 1500 out of z. rather fast when the travel is only 100x60x60. thanks for your help  ;D
will talk again soon

Yes probably was the special driver that cured your problem. Great you are up and running now and hope you have good limits switches if your table is that small and you use these rapids ;D

it really doesnt matter yet as the machine is only a toy. i will soon have a new hafco hm45 to play with which will get setup properly.
any suggestions on stepper motors? i have been looking around but cant seem to get any good comparisons. was looking mainly at the one xylotex flog with there kits, 425oz. i havent had alot to do with electronics and am not sure if they are too big or not. the hm-45 have a table of 600x300x300 approx 1500w spindle motor mt3 spindle. is there a rule of thumb for this stuff?

Not familiar with the mill but from what you describe 425 should be plenty. Just get your steppers from the cheapest place you can find, they will all most likely be made in the same factory in China :)

thats about what i thought they are only $50us a piece which is about half  the nearest price i could find. want the run encoders too. not have with the open loop system ive got at the moment. have you had a go at making them or would you get off the shelf stuff?

Encoders will not make it closed loop. Mach is open loop. You can get a board from Ron Rogers that will interface with encoders and if steps are lost it will halt motoion but dont think it will correct on the fly.

Oh and US Digital sells nice wee encoders for a decent price.

so i guess that the 4 encoder inputs are for manual hand wheel inputs rather than position feedback?

No the MPG inputs are for handwheels. The encoder inputs are for encoders, they will be displayed within Mach so Mach can be used as  a DRO on a manual machine.

ah i see now. that sucks a little :)
i will just have to slow it down and hope then. do you know if i will have motor troubles if i only run 12v instead of 24v
