What a week…
I started to place the order for the extrusions at OpenBuilds.com and found out the shipping cost to Canada would be 218$usd + customs. I then found a local supplier in Montreal and called for 3 days in order to get a quote. I finally gave up on this supplier and looked at imperial extrusions instead, which are way easier to find in north-america. I found a distribute for 8020 inc in Ontario and then decided to change the current design to use imperial extrusions.
While modifying the original design, I also spent some time trying to identify possible ways to make the design / construction easier. I then decided to change the bottom frame of the machine for one that would be easier and cheaper to construct.
- 7″ Z clearance below the beam
- 750mm x 1150mm work area
- Spindle extend 5.5″ outside the front of the frame in order to be able to work on vertical pieces
- Minimized / Simplified aluminum plates
- Working table cover tracks / lead screws
- There will be enough space in the back of machine (where the spindle can’t reach) to actually put all the electronics on-board (except VFD drive)
- Fixed position limit switches with moving skids on the axis (Min, Max, Home)
- Working table made of 10mm aluminium, holes on every 4″
