Mach Screens / Re: reversing "A" axis rotation on toolpath display?

« on: March 20, 2013, 01:04:33 PM »

BUT you do have to remember what type of machine it is, the rules is for tool tip movement not always table or rotary movement.

For example knee mills are backwards to gantry mills and on rotarys you have to consider which way the tool tip moves NOT the chuck.

Just a thought, (;-) TP

IF you are not juggling offset you could probably run it as
T#101 M6

True but I was sticking with the OLD  definition of the Tool Call T#### .

It should work with all the variants of Mach3 (;-)

In General COnfig in MAch3 you will find teh setting for dwell as EITHER sec or MilliSEC.

Mach displays in conventional  axis configuration . IF your toolpath display is correct then your  G code is correct.

IF any of your axis's machines in reverse/mirror  then "it" is reversed to conventional setup. 

Just a thought. (;-)TP

OK I see whta is happening, a big ol OOPS in mach3. It does not accept the double #var assignment to the T#

What you can do is solve the T# as an equation. BUT you have to always use  numbers of 10 -90  as tool numbers

#101=10

T[#101 *100 +#101]   (= T1010)

Paul what part about the T#101 #101 is not working?

General Mach Discussion / Re: fastest way to drill.

« on: March 19, 2013, 05:47:23 PM »

You have to remember that every move has to accel to speed then deaccel to a stop. IF the move is so short that mach 3 cannot get to full speed then you are limited to the move's time base due to accell/deaccel.

Yes in this point Exact stop may be faster. YOUR moves are ONLY .5mm long but as you see you still run up against the time base of the short move. the machine will NEVER get any faster than it can start/stop on a short move.

Looking at the drilling feed speeds you are trying to "achieve" why can you NOT use a straight GO feed to do the drilling?? WHAT are you drilling?

At some point you HAVE to except the physical limitations of the machine and control software.

Are you by chance trying to drill holes with a 90deg adaptor on the Z using your VERTICAL machine as a horizontal machine??
