Many thanks Tweakie
Yes - the info was helpfull as it gave me a clearer understanding on how these things are programmed.
Have a hunch Mach 3 can do all the calculations for me as is designed for other machines aside from router tables - such as lathes etc - it's a case of finding out how it works!
I tried setting up another profile for wrapping only, but all the changes I did there reflected back into my router table profile....grrr!

I've just upgraded my Multicam router engraver (8ft x 4 ft) with Mach3 and am delighted with the result!
Am now trying to figure out "wrapping" using my 4th axis and would like to connect up with with other guys using similar set up.
My current frustration is trying to draw a wrap in V Carve pro - seems to be an issue getting the Z set right - have figured that the  cutting depth is homed at material centre (Y), but not getting a 360 degree wrap and in the  3D view. I'm having to set material thickness at half so only see half the material in 3D preview......Grrrrrr!
Also trying to figure out calibration of  4th axis - logic tells me it would have to work on degrees rather than a lineal measurement, but can't see how to do it.
Have been in the CNC  game for over 10 years and can see great benefit in sharing ideas etc. I operate a 3D signage manufacturing business here - shopfront signs, light boxes, engraved timber signs and so on.
Look forward to connecting up with similar 3D chomping operators around the world......Cheers!

General Mach Discussion / Re: Mach 3 Upgrade issue - for a frustrated Aussie

Many thanks tweakie

That sorted the problem. Something I still don't understand though - the spindle control (inverter) when operating direct it's rotating the spindle counter clockwise. In swapping the wires over as you suggested it got the spindle running clockwise from Mach 3 but the spindle control is opposite. It was doing this before I swapped the wires only it was counter clockwise from Mach 3 and clockwise from the inverter.  As I'll be running it from Mach 3 it's now OK

Appreciate your help

General Mach Discussion / Mach 3 Upgrade issue - for a frustrated Aussie

« on: March 04, 2011, 09:28:27 PM »

Hi folks - I'm a new bloke here - upgrading my router/engraving machine with Mach 3 and hoping to get it running over the weekend!
I'm just out of Sydney, Australia - we have 240v power here - unlike the yanks with their 115v. I've wired up my Perske spindle router through a Mitibishi inverter and is running OK - only arse about - or counter clockwise.
The manual tells me I can change to clockwise by using an M code, but I don't know, can't see how to do that.
Other option is to swap the power supply wires around - but not sure thats OK to do. In USA they connect 2 115V supply wires to each terminal - here we connect 240v to one and neutral to the other - have a hunch they are the wrong way round - can anybody help - I think the M code is the way to go - if only I knew how to do it!
