Hello,
I am designing a 8020 aluminium frame CNC.
I will post someday pictures of the full machine I intend to do.
It is partly based on what Arbo has made, but adapted to european standards/shops.
For the moment, I have troubles with my Z axis design that you can see in pic 1.
For those who know, I have used carriages from Ahren Cncrouterparts.
My concern: how to get the maximum travel on z axis.
Lets have a closer to my design on pic 2
On this picture, I have put the z axis as low as possible.
For me, the available travel is min 30 mm (cf. picture), depending on the length of the bit I will use.
How can I increase this travel?
Fix my router further down on the interface plate? I fear cantilever...
For the moment the router is fixed 30 mm below the carriage (see pic3)
Can I increase it?
Other solutions you have used?
Like the one proposed by Ahren on his site, consisiting in fixing the carriages on Y axis & letting the 8020 of the Z axis move up & down? Any feedbacks on this?
Thanks
