Gantry style CNC mill

**routercnc** · 25-07-2017

Nice work so far. Can you show the detail behind the Z axis top covers. I'm guessing servo drive via belt to the top of the ATC spindle pulley?

Also, are the gantry ends just covers, or machined from solid (!)

I've looked at that skyfire spindle many times before and been very tempted. Let us know how you get on with it.

Ive also considered the skyfire spindle. I may pull the trigger on one and report back.

looks brilliant!

hello everyone!

the gantry ends (and all other parts) are machined from solid 7075 T651 but those are covers as well.
i'm including some images without the covers for clarification

Updates
this week iv'e FINALLY got my UDOO x86 single board PC which will be paired with Dynamotion's Kflop motion controller to create what i hope
is the best hobby solution today for machine control. (more updates on this soon)

Hi giladv,
Very interested in your project as I am thinking of building something of similar compact size in the near future and your design looks great.

I also use Kflop with my CNC mill and I love it.

One question, the 1.8 spindle servo, can you tell us what servo you are planning to use? Is is a dedicated spindle servo for higher revs or just the usual 3000 revs?

thanks!
regarding the spindle: the ac servo should be 3500 rpm max (with the driver itself i was able to go only to 3000rpm).
but there is a 1:1.87 gear ratio between he spindle and the motor. so i'm planning on around 6000-6500 rpm at the spindle tip.

best,
Gilad
