Acorn retroSharp NC OD Grinder

[acorn_automation]

Retro a Sharp NC OD grinder. Used Yaskawa Sigma 5 setup for pulse and direction.
Wrote custom macro programs for course & fine infeed with reciprocation; and plunge/dwell grinding.
Machine works to less than +/- 0.0001 finish on parts. First production run of 33 pieces all dead on the money, perfect.

When running the DRO shows 4 places after decimal; since working to 4 places, truncated or rounded-off position is confusing. Want to change DRO to show 5 places after decimal (0.00001). Parameter #143 controls DRO digits, currently set to default of 11.0; not sure how to set proper bit when parameter is shown in decimal. How to do

Thanks.

Please confirm you are using the correct manual for your version of CNC12 as DRO precision is controlled by parameter 263 in newer versions. The best way to set this would be in the Acorn Wizard under Preferences > CNC Control. Parameter 263 should be set to 5.0 to display 5 decimal places on the DRO.

In general, the parameters are all displayed as floating point values. For bit-mapped parameters, you need to ignore the decimal point and add the correct values to set the desired bits. For instance, if you are setting bits 1, 2, and 3 then you would add:

Code: Select all

2^1 + 2^2 + 2^3 = 2 + 4 + 8 = 14

and set this sum in the parameter.
