Hello from Grenoble

[Doddy]

Welcome, Lewis.

Re. an earlier question, elsewhere, on the back panel on the Z column - have you checked the exploded diagrams on Arc's site (spare-parts)? It's admittedly not very clear (it doesn't include the two bolts that are there). This is one area I've modded on mine - there's only one bolt there now (had to cut part of the casing to fit the Z-axis motor mount). My machine is bolted to my bench and levelled - if you struggle to get the cover off I can unbolt to investigate but I expect it'd be easier to check yours?, feel free to ask if you do need me to take a proper look (I'll have to unmount some of the control boxes that are bolted to the column through holes I drilled and tapped into the column for this purpose). I can't remember any significant problems working on the Z column.

This is a (poor) image of the back of mine when I had it in bits (with new ball screw/nut and a limit sensor)
