If you have 13 to 40 and then 40 back down to 13 then you would have 1 to 1

Hi Moto, check post # 1, timmy states that he's got 13 on the motor driving 40 on the jackshaft. Then on the jackshaft he's got another 13t gear (chain sprocket) driving the chain. No mention of the second 40t. If he had what you mention in post #13 then you're right, it would be 1:1, as such he might as well have put the motor directly onto the chain.

ok so its been a while, its end up yes everyone is right it does still stay three to one, i hooked up my motors and with 1/8 step mode i end up with 1000 steps per inch, not the best resolution but probably ok for my plasma i do have different gears so i could get 7-1 which i may try out, i do have a question about 1/8 step on a xylotex board is there any plus to using it?? or any downfalls?? thanks for the replys

1/8 step is microstepping and really helps smooth the motion and reduces problems with stepper resonance which can cause lost steps and certain feedrates.
