General Mach Discussion / home and limits question
« on: May 23, 2007, 04:25:05 AM »
Hi all

When axis go home they hit the switch, decelerate then back off (as of course they should).
When an axis hits limit it stops instantly (which I think is normal) but... can Mach3 be configured so that they decelerate? (like home but obviously with no back off).

It just seems that if there's room for a decelerate after home switch hit, then why not after limit switch hit? I'm thinking it would be kinder to the machine.

Cheers

thanks chad - right on the money.

I'd switched off "output arcs as linear segments" in my CAM (RhinoCAM) which meant this was the first time I'd actually posted a real arc (G02 and 3) so this was the first time Mach3 cared about this setting.

Thanks both for your help

Many thanks Graham - problem solved - strange though, havn't had this happen before... Though I have just reloaded Mach3, but can't remember setting this before.

Anyway thanks again for your quick and spot-on reply

General Mach Discussion / arcs gone wild
« on: May 12, 2007, 03:55:11 AM »
Hi all

Has anyone come accross the problem of Mach3 getting the centre of G02 G03 arcs a country mile out? I have a simple toolpath to cut out a rectangular profile. Each corner (of the toolpath) is an arc which should have a radius of around 7mm according to the g-code. However Mach3 interprets the radius to be massive so I end up with a toolpath resembling a rectangle with huge "micky mouse" ears!!!

Sorry - can't seem to figure out how to attach images code etc...

Any comments, advice would be welcome.

Cheers

General Mach Discussion / general wizard problem

Hi all

I'm new to Mach3 (and this forum) but seem to be getting the hang of things - apart that is - from the wizards. It seems that whichever one I try they just won't let me set any of the values in the dro's. Soon as I defocus any dro the values return to their originals. I'm guessing I've missed some vital instruction somewhere but I've RTM and searched the forum with no luck. Any help would be appreciated.

Thanks
