3 Axis 900x500mm

[Wal]

A little more progress today - I might have got a bit more done, but there was a bit of a fire in my neighbours house while they were out walking their dog - I smelt burning plastic, saw a few wisps of smoke coming from an open window and called the Fire Brigade. A laundry basket left on the stove, apparently...

Firemen did a great job. Loads of smoke but no severe damage - I imagine that there'll be a fair bit of scrubbing to do over the next few days...



Anyway. I made a couple more of the L brackets, these needed slotting for a bit of built in adjustment - nice to have those extra long 5mm end-mills to hand...



Then it was on to the spacers. First I machined a channel for the L-bracket to sit in - the channel would also locate onto a fixture so that the reverse could be machined in order for the spacer to locate into the extrusion:





It's looking like it should work okay:



One thing I have noticed is that I won't have as much cutting area as what I say in the title of this build - despite the Y gantry being 670mm across, it's going to be more like 460mm rather than 500. I can see myself having to go lock to lock with the Y axis - and as a consequence I think it's a bit hopeful trying to squeeze in the limit sensor on a bracket of some sort. I'll take out the existing support and cut a section out to accommodate the sensor. Ideally the hole would be a bit lower, but bugger it - I'll make the targets a bit bigger.



That's about it for now - the other E-chain should be a bit more straightforward, so I won't bore you with progress on that one.

Wal.
