Newbie- can't get Mechine zero

[electric2u]

can some one help i'm trying to set up my table and can not get the table to set to zero i looked at the online stuff but what did i miss?

[Avion c130]

what kind of machine or control are you working with?

[ger21]

Can you explain a bit more what's happening? Are you using Ref All?

[electric2u]

yes i hit the relef all in the DRO part and the numbers will not go to 0 i type in 0 and still nothing ( i'm trying to set up my table not on a part setting the limits and home switches) and have the machine coord highlighted in red. i'm using mach3

[ger21]

Do the DRO's change at all when you click the Ref All button?

Is there an error message?

You can't type in 0 in the DRO when in Machine coordinates.

In the Homing Limits screen, do you have any humbers in the Home Offset column?

[electric2u]

ok i can get it to 0 now but when it hit the home switch i get and error (home switch hit home it and fix it) something like that. it won't home all three at one time. it stops at the first one with that error. one other thing i have two motors on the X i slaved the X to the A i had to set up the home and limit to the A axis. is that right? it works now, just can't get them all to home at the sametime.

new thing now, i did my fist cut of my name, but it cut reverse or backworks looks good it is just backwards. what did i do Wrong because something is not right

thank you

In Config/Ports and Pins go to Motor Outputs, and change the Direction pin (from High Active to Low Active or vice versa) of the motor that controls the axis your text is aligned to.

new problem if you can help, thank you for your help on that one

when i'm running a gcode my z axis seem to losing is calibration. it stepper don't change (in motor tuning) but when i tell it to move 3" to well move something like .40" and the z axis is moving alot fast to. now when it was cutting i did play with the feed rate. it has happen like three time now and everytime i have recalibrated the axis. i would like to trust it to put a good piece of wood in there but not there yet but getting closer.

thank you
