yes, he uses the csmio-ip-a that links to the PC with an ethernet cable.

Its alive !!!!

Still got to mount the spindle, wire some limits, tidy, PID tune, test. But getting there.

So I tried to do the 'double up' with the limit switch for X. Make it home and limit. It goes home, but then when you try and drive the machine manually it says 'limit hit'. I know there is a manual override on the settings page, will try that.

Holly Jaws!!!

you are almostthere!

So, managed to make a small cut, nothing exciting. I need to sort the table. X and Y limit switches mounted and wired in. Having an issue with my Y motor holder, its not 100% level and causing issues, will sort.

Any thoughts on what I could use as a table? Ive seen alu T plates and similar for sale on ebay.

Argh, good progress, getting tuning right and then with the limits / home switches I was doing some test. I ended up somehow going past the X ++ endstop which has fortunately only cost me lost time as I now need to repack the ballnut and some of the cart bearings. Could have been a lot worse. Not sure why it ignored the limit switch.

I was setting the X and Y axis to be reversed as they are the wrong way around ( + and - direction ). Do people normally do it on Mach 3 or reverse either the -10 to 10V or swap motor leads (and encoder feedback)?

Bad luck Chaz

However I do seem to remember posting this about a week ago (post #283)

"However my personal preference on big powerful machines is to have the home switches inside the boundries set by the limit switches, and have the limit switches trigger powering off of the drives. Also to have the limit switches within the boundries of mechanical stops that limit travel before ball screws over travel."

Hi Andrew, would a latched relay be suitable to perform the functions you describe?
