    Will be doing this morning when I can drag myself back to work, I have no homing switch on the Z so I manually home. Will need to buy bigger energy chain to sort, also need to make a better mounting plate for the energy chain on the Y axis which isn't straight and keeps coming apart. I suppose I can now use the machine to make that bracket but probably just measure, mark and drill.

    Very impressed with the cut from the 2 flute 6mm end mill on the laminate I was expecting mega chipping.

    Because I only clamped one side it wasn't even so the white wasn't milled out properly but it was only a test with some scrap so happy how it came out as soon as my clamps come (Ordered 4 toggles clamps going to use 2020 extrusion across the bed instead of steel.)

    Need to flatten the mdf bed as well, gong to get a 1/2" trend straight router bit to do this as it will be a lot quicker.

    Be quicker still with a 50mm https://www.wealdentool.com/acatalog/Surface-Trim.html or similar

    It came so fitted it, think I'll put it sideways on though so I access the flip for changing bits easier.

    There's 1 more piece to come

    60*60*3mm box section steel 2.1m lengths going to use this to upgrade my router so work isn't finished yet lol but it'll take me a few months to raise the money for 25mm Hiwin's, proper R&P for the 2m axis and I want to swap my gantry ballscrew to a 10mm pitch. So plenty of time to play with her for the time being. I'm thinking of taking my gantry and dropping it on a frame made from this. I have loads of 40*40*1.5mm box section I can use for bed supports (Again free, sometimes it pays to pikey everything you see lol even if you sit on it for 3 years)

    My favourite price free ;)

    This will offset the not free stuff I had to buy lol

    ordered a cyclone was going to homebrew but price was too good to bother.
    https://www.ebay.co.uk/itm/Cyclone-P...72.m2749.l2649

    and got a vacuum cleaner finally I had 3 2.2kw but wanted something a bit more reasonable to run so gone with a 1.2kw miele with power control can drop it as low as 250w cost free ;)

    I noticed that your cy cable to the spindle is not secured in that every time the Z axis moves the cable gets bent at the plug. This is a major fail factor and might destroy the VFD as has happened a few time here. Can you put a supporting bracket from the Z front plate to fix it.

    Yes I can, I had noticed of course but keep forgetting I actually unsoldered it and tried to sort it out but still ended up the same lol.

    Luckily there's a lot of scrap kicking around the yard so sure I can find something to do the job or actually desolder it get the cable in properly and resolder.

    I had to wire my control box like 4 times lol this is pretty standard for me although I am getting better each time.

    After blowing up a transformer it would be good if I didn't blow up the vfd lol.

    Every piece of advice you have given has turned out to be the correct choice so I've learnt to heed your advice lol just wish I'd spoke to you before I ordered my ballscrews.

    Been ringing round for quotes on steel and it seems for another £100 and with the steel I already have I could make a frame 3m*1.5m quite comfortably with bed supports (No legs). That started me thinking if I buy another 2* 1.5m of 15mm Hiwin rail I could have the end cuts straight and then butt them together to extend the travel. Then I only need R&P for the now 2.7m axis and probably some motor upgrades and I'm good to go. I might even be able to make some legs out the bits of aluminium left over when I strip Betty or from the 40mm steel. I have 20 1.5m pieces of that again free ;)

    But essentially I can convert to an 8*4 for under £1k but only with 15mm hiwin's.

    I can get nema 34's for free in fact I gave away ~20 last year, I've said it before and I'll say it again check your local scrap yards it's criminal what's being scrapped ;)

    Overnight made my decision Betty's getting upgraded but will take me several months at least, what scares me the most is the rack and pinion for the 3m axis someone on here hasa plasma cutter setup this way they are going to learn to hate me lol.

    15mm just seems too crap found 3m 25mm Hiwin's for $600+import tax I think this make sense and sell my 1.2m Hiwin's with ballscrews and motors.

    Nema 34 the R&P, use a 4nm nema 23 for the gantry and use my existing gantry. Will need to remake every plate but now I have the machine working that's no biggie.

    So to that end I spent this months budget on
    https://www.ebay.co.uk/itm/112394613868

    Now I need to work out how to fit lol, I have a vague plan of fitting the BK15/BF15 upside down with custom adapters I'll make so it lines up with the existing motor mount for the gantry. I also might need to remake a Z axis plate we shall see.

    Im envious of your drive (and time.. most of all time)
    Arent you atleast curious about your current machines limitations and capabilities?
    Understand me correctly now, if you learn more on whats failing on your current build you might get better insight on how to make it better? :)

    It'll take me 3 months to scrounge the parts so plenty of time to work out what I want to change but there's 2 things I already know.

    I need more travel 1.8*0.8m at least and I need it to work faster a lot faster:)
