Been a long time.
My 525 build has been sitting on its side for a couple years in the basement. Now I’m trying to upgrade to Primo, but I have a hard time sourcing the parts, much harder than 525.
I got the 10mm GT2 pulleys and M5 nylocs from the shop I bought my first printer from, but I have trouble finding the other parts. M5x30 machine screws are most difficult. Home Depot only carries up to M5x25, Lowes and others only sell in packs of 2 to 7 and no one store has 65 all at once. Three maker shops I checked with do not have them in the right length. Fastenal will not do cash sale, no idea about Grainger, and I just cannot find a place in Toronto where I can buy them in boxes of 50 or 100. M2.5 for the endstops I think Sayal has, but #3 screws are nowhere to be found. I have to stick with 5/16 instead of moving to M8 so I can reuse my previous box of 5/16 nylocs, not to mention M8x40 costs more than 5/16x1.5 at HD where I bought them. I also may have to keep my 525 feet and its 6-32 screws so less for me to worry. I also can’t find the exact 10mm GT2 idler, to the point I may have to make do with 6mm idler and not upgrade the belts. Print myself some spacers.
I really miss the 525/Burly composition where parts are easier to get from one big box store run. Now I have to go look for curtain rods or metal shops and order from multiple places, and success is still not for sure.
I need pointers around Toronto.
Belts I can wait until I finalize the size. This time I want to have about 350x200x200mm, sized after the Wanhao i3 I have, but with extra X so I can mill a bezel for my low profile uATX case.
4th axle and aluminium are in my future.
