General Mach Discussion / Power cut caused mach3 problems

« on: November 24, 2011, 06:54:31 AM »

Hi,

Had a Power cut while Mach 3 was open and the PC switched off suddenly. When started back up the home and fixture position was different. Also the X axis has switched, i.e. when jogging X go's in the opposite direction now. Also I have a 'Normal Condition' LED flashing on the Home Page ( when clicked it says 'Axis are not re-fed to normal position').

Any help or suggestions of how I get back to normality greatly appreciated. I am a newbee and only in my first few days of Mach 3.

General Mach Discussion / Newbee needing some advice on v-carve circle coming out as an oval :-(

« on: November 18, 2011, 10:00:40 AM »

Hi all,

I am James, just got a secondhand cnc router working manually and I can also send v-carve generated .txt files to mach3 and they run and cut.

Problem is that all data seems to stretch in height (Y-axis). if I do a circle in v-carve software it comes out as an oval when cutting on the wood.
I do a 20mmx 20mm square it comes out as a rectangle.

When I did a sign which was imputed as a JOB SIZE 100 x 250mm in v-carve the letters when cut were central to the 250mm but not central to the 100 mm height.(positioned high)

Any ideas what is wrong and how I can correct it??

Any help will be greatly appreciated.

James
