I've not slaved the 2 side together yet just so i can confirm each side is working correctly. I've no tightened things up yet so there's enough slack in the gantry to allow independant movement of each side.

The pendant plugs directly in to the BOB, not the PC so commands as different and with this working i though jogging via Mach would be fine.

Well it turns out that the pendant does conflict with keyboard jogging commands. If i unplug the pendant it it's fine and both side jog via the keyboard. They're now slaved together and all is good in the world for now and i can tighten things up.

Mach doesn't know or care what's sending the signals, it could be keyboard, pendent thru the BOB or just set of buttons on a control panel.? To Mach they are the same, It's just watching for inputs and acting on them to do the assigned tasks.

Mach doesnt need to be running or the PC can be off for that matter to move the axis via the pendant. However you cant slave 2 axis together with just the BOB without wiring 2 drivers to the same output which isnt the best of ideas. So that rules out the pendant working independantly without the PC and/or mach. Its not a big issue but was a nice to have.

Ok I see.! So the pendant has a pulse generator built into it. Think you'll still be able to use the pendent but you'll have to set the Jog mode to shuttle mode so it uses the MPG(manual pulse generator) to output the pulses while jogging not Machs pulse engine.? .. . . I'm not 100% on this but think I'll be close.!!

So how many other people got a big cheesy grin on their face when their machine move freely for the first time?

I could have quite literally smashed it to bits last night!

It was binding up all over the place and when it did move couldn't lift my weight! Oh yeah its gone vertical now to save space.

So stripped it all down last night noticed the ballnuts weren't square with the rotating ballnut mount so that didnt help.

It's now all nicely realigned, tacked and clamped (ran out of mig wire) and moves freely under the control of mach. It lifts me and 2 kids together without breaking a sweat.

The pendant has been ditched for now.

Next on the cards is the X axis......or is in now Y.......oh I dunno......beer time

Nice feeling isn't it.!! . . . Just wait until you try cutting.??. . . You'll be chasing stuff like this for weeks, maybe months before your happy. It's all par the course but worth it.

About time we got some update pics.!
