Ar last!!! Started my Gantry 3-Axis CNC Build

That one:

or just tram against the glass so that the spindle is correctly aligned relative to the glass?

Looking forward to seeing how this machine performs Mike, it's very similar to mine.

Thanks Lee - relative tramming!

Thanks Lee - relative tramming!

Assuming your going to be laying the glass on the bed, placing indicator base on this, then rasing and lowering the Z, adjusting the spindle as you travel to keep "0" ?

yes. Swinging the dial indicator left and right 180 degrees in the "Y axis" (short axis) direction, then front and back 180 degrees in the "X axis" (long axis) direction.

Hi everyone

Finally done the first cuts with the machine! I have a video posted on Youtube https://www.youtube.com/watch?v=TvKm...ature=youtu.be which shows the baseboard being levelled. I'm using a 1 1/8" (29mm) diameter bottom clearing bit @12000 rpm and 3000 mm/min feed and first pass at 0.75mm and finishing pass at 0.25mm

I did'nt realise how much dust would be created, so the next job will be the creation of a dustboot for the spindle and a cyclone filter system. I initially used my trusty Aldi ash can filter, but it soon got clogged up with the fine MDF dust. It will work better behind a cyclone system.

Also, I hooked up the Huanyang VFD to Mach3 using the VFD plugin by Sebastien here
This worked first time, but when I tried cutting in anger I got and e-stop near the end of the first cut, so had to abandon it and set the spindle by hand. I'm sure the problem is due to some electrical noise somewhere so need to add an EMI filter to the VFD and earth the shield on the RS485 connection to PC running Mach3

Overall really pleased, but still spending money on this.

Thanks to all you have advised me over the years (Jazz, Jonathan, John, Lee and others) and those who have encouraged me in the build (routercnc, kingcreaky, clive s and others) . If I've missed you off the list - i'm sorry - your help has been appreciated! - I'll have more to show in the coming weeks

Regards

Mike

The cyclone cones you get off eBay are good, just hooked one up to my machine and works brilliantly, I'd highly recommend one Mike.



What you see in the bottom of the CamVac (virtually nothing) is after machining plastic for an hour and hoovering wood dust up off the floor.
