Send it all back, and build you own, the OX Machines build or drive is not tough enough to do anything other than a laser cutter or a 3d printer.
If you do keep it send back the crap electronics and get a uc300 and the hg08 breakout card from cnc4you.co.uk if you are in the UK

Also the Z axis, i am not sure its good enough for anything, I had to replace the whole z axis for one that wasn't Cr@p
on the plus side the extruded ally rail is ok, just get that and make your own without using those cr@p wheels, i am sure there are plenty of engineers on here that will help you design another one.

Good Evening All.

i am very new to the cnc world, This time2 weeks ago i new NOTHING about a cnc, not one bit , i run a small family business and decided to buy a cnc machine to see what all the fuss was about, i brought the open build OX machine and to be honest its wrecked my head ever since, even tho i haven't used it yet ( still working on putting it together) i love learning new things. but i am getting great satisfaction in putting the machine together step by step, basically its like building your own machine you have to do everything all your self,

this is the bit where i am stuck, i have the machine all connected and the control box is a LED TB6600 on the control box i have all the navigation keys Y- Y+ Z- Z+ X- X+ when i press the button they all work as they should and after tweaking the wires had them all going the right way,
Now heres my problem i brought the mach 3 license downlaod and installed ect ect set my port and pins enable my motors sorted the emergency switch out so it doesn't blink press the tab key to try and move my motors and NOTHING... the numbers on the TB660 and on the PC move like its moving but the motors ant moving, they only move if i manually do it on the control box can some one please advise a newbie.

thanks in advance Gary

everything else works ok, the machine will always go back to working zero fine, and I never have any unexplained stops, so there is no problem with noise

I have just updated the driver and firmware just in case.

If I disable the slave axis, and unplug the motor it works fine

General Mach Discussion / Homing using Ref Home
« on: October 19, 2014, 11:59:12 AM »

My Machine works well now, except, when homing the slaved axis.

The Y axis has a homing switch, agh Axis doesn't, when i select Ref Home the machine homes and then moves away from the switches, all seems well.
The problem is:  the A axis is slightly out of sync with the Y axis, and each time i ref home the error it is out by the same amount again, its about .6mm out each time i hit ref home button.

The machine is pulley and belt driven so if i Ref home 7 or 8 time in succession, the machine jumps a tooth on the pulley.

Could the Y axis motor not be in sync with the A axis motor?

If not any ideas?

I am using a UC300 controller from cnc4you

I think its down to a process hogging interrupts or processor time on your pc, like anti virus, it doesn't matter how powerful your machine a lot of software is written so poorly and with no regards for other software running

As for the machine homing, just home it after you have run the job and have finished

My A axis homes well now
