I’ve been running a “fairly stock” 2017 XCarve for a while. It was 2016 when I got it, then I bought the 2017 upgrade with X-Controller, new solid makerslide for X axis, etc.
I’ve got aluminum Y axis braces I made as soon as I got the machine up and running as to combat the gantry from sagging along the Y Axis rails.
I’m about to embark on a huge undertaking of making 150 lidded boxes 70mm x 70mm x 35mm with 25mm deep pocket cuts and some adaptive clearing cuts for wedding favors at my wedding in 66 days. I designed the boxes in Fusion 360 and generated all my tool paths. I managed to get a fairly acceptable time of 14 minutes for a 55mm (Y) x 55mm (X) x 25mm (Z) with .125" radius corners pocket cut in soft maple. I decided that I can’t stand how loud the 611 router is, and the Z Axis is horribly sloppy with those V wheels and the stock Z rail too much chatter, so I ordered a linear Z Axis upgrade from CNC4Newbies. I am going to snag a spindle, and was thinking the 1.5KW water or air cooled 65mm x 188 (or 200) mm would be a welcomed upgrade to deal with what I feel is the weakest link on the XCarve.
I know the 1.5KW spindle is about 10 pounds, so I also ordered a 270oz NEMA 23 stepper for the Z axis just because I may as well do it all at once so I don’t have to do multiple tear downs.
Is 10 pounds for the spindle too much? I tried putting a 7 pound weight on top of the 611 to get an idea of any flex or twist in the makerslide. I didn’t notice anything while the machine was off, however that doesn’t mean while it’s running it won’t be too much.
Has anyone successfully installed and run a 1.5KW Spindle on their X-Carve? Most of what I can find references 800W spindles.
