 I couldn’t get UGS to install on it a few weeks ago - can’t remember what the problem was (possibly required an administrator password?) I’ve been running everything on my own laptop. I’d also like to get a copy of Fusion360 or FreeCad or something on there. I know very little about MacBooks, so this may be annoying, and I may have to work out what the administrator password is (different to the log in password written on the MacBook).<br>

 I flipped over the spoil board and found approximately 100 pronged T nuts in the existing spoil board. I removed them, and have been able to reclaim approximately 80. I will replace them in appropriate positions and purchase botls for the nuts. I believe the nuts were M5, but I will re-check this prior to purchase

 The current enclosure is packed very tightly. A new enclosure would help reduce EMI (and hence the cut-out issue. Enclosures seem to be about £200 to buy a metal one (plastic are cheaper but provide less shielding). Cheaper option - repurpose old PC case.

 Plexer has contacted Lightburn about getting in on the beta test for their new CNC control software. Currently not open, but are on the waiting list. <br>
 Craig has suggested getting the makerspace licence for VCarve. I have been using my copy of VCarve to make my inlays, and have found it intuitive and user friendly. The licence is £100 per year, and members will have access to a version to use at home. The big advantage would be that we could set up guideline parameters for new users to flatten the learning curve and risk of damage to equipment. https://www.vectric.com/products/makerspace/

 I am making/ intend to make 2 kinds of clamps, most of which will consist of scrap wood. This will hopefully minimise damage to the CNC and cost when collisions occur. This design https://www.youtube.com/watch?si=2aUY7xtjrpurt9U1&v=O-rqf4uSXRE&feature=youtu.be<br>

 Considered adding slots to spoilboard to utilise t-slots on aluminium base, but decided against this for ease and to avoid damaging the base in case of collision with head. I intend to use roofing nuts due to the low price point (approximately £0.05 per nut in Thorns DIY, likely cheaper elsewhere), though other but types (wing nuts, T-nuts) would work too. I’d require approximately 54, at a spacing of 75mm per hole, to alternate with the dog holes, plus some bolts (think there’s plenty in the workshop) and some plywood scraps to make the hold down clamps.<br>
