Comments sought on new build: A CNC Router for RC Gliders and Planes

**njhussey** · 05-09-2016

Had a good purchase from eBay last week, a Camvac for under 1/3 its retail price. Its like new and works well.

Made a rough dust shoe out of 12mm ply and a bit of draught excluder. Just got to test it works ok before working out how to fix it on so there's access to change the bits and do the probing...

Any ideas anyone on how best to do this? I'm leaning towards neodinium magnets holding one side on...

Put the home switches on X, Y and Z, wired back to the CSMIO IPM and set up in Mach3...all working as should but still need to put "targets" for them on the machine....

Ok so I've dome the homing switches and all work. Quick vid showing this.

Seems to work ok.....however I've had to reverse the Z axis to get it to home and now its all to cock....if I try to do a tool zero with my touch plate then it goes up instead of down....just looking at the settings in Mach3 to see what I need to reverse/do but if one of you experts could point me in the right direction id be eternally grateful

You're correct Clive, knew there had to be a setting but wasn't sure till I read the manual.

Set my park position too for changing bits and also for parking the gantry at the end of the day....slowly getting there with it.

Limits next, then enclosure, counter weight, proper dust shoe, LED lights...the list goes on!!

Neil are you sorted.?

Either Home neg are use the Reverse option but will depend on how axis is setup. one of them combo will sort you.

Sorted cheers Dean, I reversed the axis but then on doing the simple tool height routine in Ger's screen set it sent the Z into the hard stop...a bit of reading the manual and "Home Neg" sorted it.

Set the touch pad for the 2010 screenset autoheight and toolchange function...seems to work well. Might change the location but will see after some use. I now change tools at the park position at the bottom, saves bumping my head!

Ok so machine is getting there....thanks to Dean set ports and pins on Output#1 to port 10, pin 4 for output 12 on the CSMIO IP-M and all is good...

Below is a quick vid of the auto height routine and then air cutting...
