Mach3 / XHC Machmotion Ethernet card slave axis

[80gus]

So im currently running to machines with XHC mack motion card one is a 6 axis (Router 4 axis and salve) the other is a 4 axis mill, both working pretty well so far.
Just tone niggling issue with slave axis it just wont do what its surpossed to, i've tried every type of script i can find on the net, sometimes Slave axis overruns, sometimes it wont run, im getting really frustrated with it. supplier/ manufacturer aint coming to the party with help at the moment either. has any body managed to work out how to do it. ive tried turning off Homing Slave with master, tried A xis as slave, Ba xis as Slave. tried The Script they use for smooth steeper homing.

Some Chinese motion units do not support full use of the slave axis (or do so badly).
Would it be cheaper in the long run to buy an ESS and cut the hassle?

Would be nice to keep it obviously, as both the mill, and router are similar components , makes testing and repairs easy. ill work with it. was hoping someone else has found a way to get it to work.

OK i had it working, 100% working every time, slow process but and dances all over the joint, but this code was working correct there overrun issue.
Then i re power the machine and haywire again, never the same fault, its almost the luck of the draw.
XHC i hope you fix this, i will be harassing you until you do. Supports slave axis, homing and full support.


so maybe others in the same boat can try this.

OK did a bit of refining this seems to be working all the time, you have to jiggle the B and Y axis to trick it for some reason. but for anyone having dramas try this, its working all the time now, the only pitfall i can see is if you at the end of your travel before hitting the cycle it will drive past the 5mm, but i never home from there anyway. Hope this helps someone else cause it took me ages to get it to work! very important Y axis must hit the switch last.

NOW i cant get Y axis to step with the Slave, when in Jog mode it does exactly what i command, then i go into step, instantly the Slave is dropped off, then back to jog it works again. XHC Not impressed, works so well without slave.

[SkyDiverDown]

Have you had any luck with this 'contraption'...

I can't get A to slave off X during run cycle.. .. It manually jogs beautifully; then when I RUN code; BLAM!!.. *Hit on the head with a hammer*..

Does this card 'require' the homing switches for the slaving to work correctly? (just an odd thought)


Any quick suggestions?
