    Hi all
    I'm sure that you have heard similar before....
    I've just completed my ox build, wired and ready to run however i'm now stuck.

    I use Vetric 2D cut desktop, and then save my tool path as a Grbl file 0.8 (mm). I then use Universal G-Code Sender to send to my machine.
    I have a machine mounted CNC Xpro V2 when using the control panel in UGS all the axis operate and move accordingly

    The problem i have relates to when i send a file to the machine, it seems that the measurements increase ten fold increasing the size from the original as designed in 2d cut

    if any body has any ideas????

    Thanks in anticipation

    Thanks Flash22 , i'm new to this and i'm not to sure.

    I initally took the settings as listed on the Ox Build page, not realising that there had been a changed from 6mm to 8mm Acme screw thread size. That i believe is the only setting which maybe at doubt as the motors, pulley and belts are all the same as the original build.

    At the sound of seeming lazy... are you aware of a set of generic Grbl settings for the Ox as configure with the X pro board that, i could possible use as a reference?

    i haven't really referenced any other literature as such other than whats supplied from the kits manufacture, which didn't list any details about the controller setup as such

    I have rewired and reprogrammed the unit now and still it all seems out of scale i would estimate by a factor of ten

    Iv'e really enjoyed the build, just struggling with the electronic at the moment, i'm sure its something simple that i'm mising

    I'm not a ox user but have the c beam, there are various threads on here with the info you require, I had the same issue - I had forgot to set the micro stepping on the board

    the board just has default settings and you need to change them to suit your build

    have a look here.

    Yes these are the setting i refer to in my last reply. I been experimenting this morning with the stepper motors and i think the problem may be with the board as i see no change in the problem when i increase or decrease the step size! i will keep on persevering. many many thanks for your input and comment

    Is that by the physical microstep jumper on the board ?

    UGS if you jog the table with the buttons what sort of movement do you get (make sure its set to MM first as it defaults to inches)

    Hi Flash,
    I have just uploaded the firmware, and i think it may be OK.. not sure just plugged in a few settings and the x and y look OK, can't believe it, its been a long day and i'm turning in. I will keep you posted, if interested, just like to say thanks for all your help, time and suggestions. Not there yet but making progress

    Paul
