Wow thanks craig, Yes i am aussie thanks for noticing  lol

As i was building i wanted to get the best i could afford hoping i could build something semi impressive but reliable haha

Just wanted to double check in the motor tuning tab am i still sticking to 400 counts per unit? or am i still way off.

Hi craig chucked in those assumptions and she is definalty moving a bit better.

I post a link to the driver spec sheet
http://oceancontrols.com.au/files/datasheet/lea/SMC-180_ES-Dhm_V1.1.pdf

I'm running the larger one and they are direct link coupled, i turned up a aluminium couple on my lathe and i can confirm they are 100% 5mm pitch ballscrews.

Ill watch some more youtube videos on g code but yeah i was just jogging to unit.

Hope that helps a little

Regards Dale

Also wanted to add in the wizard i have my settings as

1000 counts per unit
100 units velocity
10 acceleration units

no idea if these numbers are right but when i move 10 units it moves 63mm and when i try to input that new length the number gets amazing small and my machine is crawling along like a snail

Thanks for your help guys, i suppose ill start from the begining

On the stepper motor controller units i have it set at 2000 pulses per rev but im not really sure if that works as everything is moving at a snails pace now
and with 2000 pulses what does that equate to in my current steps per revolution just to give me a start point
