General Mach Discussion / Jerky transition between inline arc movements
« on: October 29, 2011, 04:22:44 PM »
Hi,
I fairly new to Mach3 (but well versed in shopbot)
I have played around with CV settings, but cannot get my cnc to transition smoothly between arced paths that meet straight lines and each other in line using G02 commands in a tool path file. I have cv on with distance set to 2(mm), and find I need this to stop arcs forming around any angular change in direction (with a bit 4mm dia and over). The machine slows up like it were going round a sharp corner - but it isnt, but not on every transition.
The following code does it around 4 times, though it is cutting a single large circle:

General Mach Discussion / DRO font size
« on: August 21, 2010, 06:18:16 AM »
Hi, I am a complete starter with this program, just downloaded and set up, and just joined forum. I need to get up to speed on basic using as quickly as possible.
Is there a good site/forum for getting going and basic config?
My first issue is font size in DRO's, especially in the surfacing wizard, where I loose the values as the font is too big for the slot. I work in metric, with xp on a 1400  * 1050 screen. I have tried changing the font size in Function cfg's but it just goes back to 18. Can I reduce number of zero's after the decimal point? Can I change it so it justifies from the left? Any help on this most appreciated, as this is the principal function for a new machine we are getting in soon, and I would like to get it sorted and expand from there.

TIA,

Ralph.
