Clearing the memory,

[CharlieM]

I believe there is a Code to put at the beginning of a program that clears the memory of commands in previously run programs. It looks like my Kellyware program is remembering the feed rates in an earlier program and ignoring the new feed rates.

Any help is much appreciated.

I guess you are talking about KCam?

What G and M Codes does KCam support?
KCam supports G00, G01, G02, G03, G04, G45, G73, G80, G81, G83, G90, G91.

KCam supports M01, M02, M03, M04, M05 and user defined M codes.

I write all my programs manually, when useing my old "Master 5" program I could put ( Z-.25 F.75 ) on a line and the quill would go down .25 at a rate of .75 inches per minute, on the next line I would put ( Z.0000 F12 ) and the quill would retract back to its home at a rate of 12 inches per minute. with the "Kcam" program, it ignores these comands and does something that it has learned from a previous program, or I don't know where it got it's information! Surely, "Kcam" can duplicate this feat if the right kind of commands are given to it. Now I can go into the table setup and put the max feedrate for the Z at .75 and the quill will drill at .75 but retract at .75 also, well I can't wait for that kind of performance.

Another question, Kcam supports G45 and G73, what do these commands mean?

[CharlieM]

never mind about G45 and G73, have sence learned what they mean.

I learned a long time ago that if your control is ignoring feed changes, re-iterate the "G" command at the beginning of the line where the feed is changed, even if you are doing the same motion. For instance, if you are feeding in a straight line (G1 or G01), at 10 ipm and want to change to 12 ipm on the next line, re-iterate the G1 (or G01) on that line with the new feed code. In some controllers, you can use a "." (decimal point) at the beginning of the line to make the controller "notice" that line, no matter what. The lines beginning with a decimal point are usually referred to as "definition blocks" as they "define" something important. They are often used to set "sticky" values, such as spot-drill dwell time, and such (i.e. .G04/dwell time code), but will make some controls pay special attention to whatever follows the dot, regardless. Of course, that would force you to make every feed change line a definition block, so try the G-code reiteration first.
