The Mrs aint gonna be happy about this little project!

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.!

You will spoil the photo if you tidy up!

Ok here's a few pics....

Main 70v PSU with 24v safety system and 5V for BOB mounted on a temporary board.


Frame layout. 60mmx60mmx5mm frame for rails with 100mmx100mmx4mm for the upright frame. One side fell over while i was realigning the other side and flattened me!


X rotating ball nut


X ball nut and stepper


X screw clamp. For some reason i asked for 10mm to be added to the mounting face of the stepper mounts. Cant remember exactly why but that's put the 2 screws out of line with the rails. No biggy.
The camp is made of 60mm box section with 2 aluminum wedges inside that clamp of to the screw when bolted together. They also wedge thigh inside the box section. 50mm box section is welded underneath and slide in to the main frame.


This is causing me a few headaches. My plan is to join the Y 2 bearing mounts with a 20mm plate and mount the ballnut mount to that. Im also going to increase the with to 200mm

Alternatively, and this is going to mean major surgery, move the plate joining to 2 X screws together to the back of the black box section and sink them 20mm further in to X uprights. The ballnut mount can be mounted directly to the Z backplate.
