What version of MasterCam are you using?

On mine it is stored in macx/mill/post

Mueller I've been using the original limit switches on my Bridgeport for around a year now, I've found them to be quite accurate but it does seam to depend on the speed that you home at.
Give them a try!

What doesn't work, the Boss_Mach3.txt, if so have you changed the .txt to .pst and if you've done that what's the problem, try and be as specific as you can and I might be able to help.

Thanks but I want to know if it's possible to alter what the G84 code actually does in Mach.

Graham

I have thought about using one but I'd still have to alter my program to do it which I'm already doing with my floating tap holders, yes it would save me reversing the spindle a few times and possibly cut the cycle time down but the ones I seen are fairly long so I'd have to drop my table every time I used it, the Z axis movement is very limited (bridgeport series 1).

I thought there might be a simple way of changing the way G84 works so it waits until it's seen spindle movement before feeding out of the hole, I've got a input from the spindle to tell Mach if it's spinning or not.

Here's a example of what I'm currently doing.

N1M00
N2(M4 TAPPING HEAD|TOOL - 34|DIA. OFF. - 34|LEN. - 34|TOOL DIA. - 4.)
N3T34M6
N4G0G90G59P10X-9.Y20.S100M3
N5G43H34Z5.
N6X-9.Y20.F70.
N7M98P001
N8X-45.Y8.
N9M98P001
N10M5
N11G91G28Z0.
N12G28X0.Y0.
N13M30

General Mach Discussion / How do G codes work and can they be changed

« on: February 12, 2007, 06:11:08 PM »

Hi

Is it possible to change a G code i.e. G84 or possibly make a new one.

My machine has a manual spindle start switch and a automatic spindle off via Mach so when you doing a simple tapping routine you can't use G84, as G84 for some reason asks to start the spindle, so you start the spindle it feeds down tapping the hole reaches the bottom of the hole stops the spindle, asks for a spindle start in reverse then feeds up before I've started the spindle breaking my tap, well it would if I let it run.

Thanks

Chris

I'm fairly sure it will work right if you regen the toolpath before running.

I think it is about right now, cheers.
As Joe said changing the tool offsets or work offsets and just running the program causes problem but it all seams fine as long as you Regen before running.

Thanks again

Joe

I'm running mine at around 2000mm/min (80ipm) but I fairly sure it would probably run faster I've just never tried as I'm happy with that, my machine also has different ball screws than yours so probably isn't comparable

It's a series 1 Boss 6.1 using the original drivers and stepper motors, It's a metric machine with 0.01mm steps.

Just out of interest do you reset all your tool offsets for each job or do you only do one job on your machine, I'm intrigued as to how you work?

Yeah version R2.0.011 to R2.0.014 where nearly there, there is just one slight problem with this version, if you use G2 or G3 codes you may have problems as reported a few post back.

I have a brigdeport boss machine with a knee so find it very usefull to set all the tool offsets as positive and use a Z work offset, this way I can do different jobs with different table heights without having to reset all my tool lenghts.

Cheers
