Good day guys

Hi ... - the meters are for the servo motors and for the spindle.

It's been a while since I posted but I was absent for more than 10 days and the work on the CNC has been slow... but we've picked it up again.

Pics of the progress - all of the mechanical work on the electronics is done, time for wiring. Yesterday we've got the table done (the slides for now). I hope in a couple of days to mount the lead screw and the motor.

Also we've started working on the spindle - pics of it soon.

Cheers smile

Looks great! Lots of parts, should be a good CNC machine! I got mine on hold, yet I know where to get all my parts finally.

Hope you can get it running up soon, Be nice to see how it runs :D

Hi guys

it's been a while since I last posted but a lot of work has been done on the mill. I got the servos running, the wiring of the electronics is 90% done, the Y-axis is almost completed. Last night we did some test and it reached 60 inch per minute but at half the supply voltage. So 80 even 100 inch per minute should be reachable.

Working on the covers and protective "belts" for the linear guides now.

Here some pics

Cheers smile

Very professional looking :)

Good craftmanship in hobbies and thoughtful construction is what makes a special project, looking forward to see some serious milling!

Hi guys

thanks for the kind words smile

The PTFE is quite hard. This one is specially designed for industrial air compressors(for the segments) .

We had a small incident - a screwdriver got between the support of the linear guide and the linear bearing - it got bent without even noticing it (and it is 6mm thick).

Also the nuts sit in a "clamp" - if the load becomes too great - they slide out of it. This was tested by deliberately "jamming" the axis - it worked perfectly.

Here are the pics of today's progress smile

Cheers :)

I am trying to figure out the purpose of the vertical blue sheet. The bottom one is to trap waste I assumed, but I can't think of a use for the vertical one.
