Upgrade? Chinese CNC Machine

Ok divide 200 ~ (the 'steps-per' that is set on the axis in motor tuning) by the cut measurement minus the cutter measurement(Dia 3mm as the software is running in metric mode 0r 1/8" if you require brain drain ), and then multiply by the measurement you told it to cut which was 100mm..

I get 1500.68 methinks I did summut wrong

Carl measure the pitch of the leadscrews

why not just follow 1 path at a time then the chap wont get too confused..

Agreed......

Just turned it over and measured the Y and I get 3 to a cm - whatever that works out to *shrug*

3 turns to a cm yes? What ever they are i suspect the pitch is not the same for x and y

Yep 3 to a cm the biggest problem with trying to measure the X is it is fully enclosed and I'd pretty much have to tear it apart to get to it but I shall attempt to get a close as damn first :)

Dont bother it can be worked out with the software al be it a little long winded..

well that was easier than expected, managed to get a 1cm wide flat file between the frame work and as near as damn the X is 3 turns as is the Z, so all the screws are the same size

confused but could be possible?

7.26TPI 0.13774" 3.499mm pitch is about as close as you could get to that. Stick with tuning it out for now like Rick said before. Imperial or not you would still like it working with what you have. Sorry i took this away from that.
